Method and system to contextually initiate synchronization services on mobile terminals in an enterprise environment
US 20060075075 A1
Abstract
A system and method are disclosed for providing security features to a wireless mobile device based upon its context when it establishes a wireless connection with different access points. A plurality of access points are connected to a connectivity server which includes a security context middleware. Each of the access points also includes a security context middleware. Furthermore, each mobile wireless device includes security context middleware. A context manager program in the server determines a context for a wireless mobile device from a signal received from an access point indicating that the wireless mobile device is wirelessly connected to the access point. A database connected to the server stores security feature data which is accessible by the determined context to implement a security process. The context manager accesses the stored security feature data based on the determined context and sends a command representing the security feature data to the middleware programs in the server, the access point and the mobile wireless device to implement the security process in the mobile wireless device.

Description
FIELD OF THE INVENTION:

The invention disclosed broadly relates to context-dependent services for mobile terminals and more particularly relates to context dependent security features in communication, to properly authenticate and secure communication links for short range RF devices based on the current context of the device.

BACKGROUND OF THE INVENTION:

Short-range mobile wireless devices frequently come within communicating range of stationary wireless devices, known as access points, which are connected to wireline local area networks (LANs) or wide area networks (WANs). The mobile wireless device can form a wireless link with a nearby access point to enable communication with network servers. The network servers can provide services to the mobile wireless devices, which can be customized to the particular access point currently nearest to and communicating with the mobile device. An example is a business enterprise's office building having a lobby area with an access point near the entrance and various offices and access points distributed within the interior of the building. A first access point in the lobby can provide to visitors copies of company brochures and office maps that are downloaded to their mobile devices from a network server. A second access point within a company employee's private office can provide copies of company confidential documents downloaded to the employee's mobile device from the network server. Clearly, there are different requirements for user authentication and document security in these two examples. What is needed in the prior art is a method to provide context dependent security features for short range RF devices based on the current context of the device.

Short-range wireless networks include both wireless personal area networks (“PANs”) and wireless local area network (“WLANs”). Both of these networks have the common feature of operating in unlicensed portions of the radio spectrum, usually either in the 2.4 GHz Industrial, Scientific, and Medical (ISM) band or the 5 GHz Unlicensed-National Information Infrastructure (“U-NII”) band. Wireless personal area networks use low cost, low power wireless devices that have a typical range of ten meters.

The best-known example of wireless personal area network technology is the Bluetooth Standard, which operates in the 2.4 GHz ISM band. Bluetooth is a short-range radio network, originally intended as a cable replacement. It can be used to create ad hoc networks of up to eight devices operating together. The Bluetooth Special Interest Group, Specification Of The Bluetooth System, Volumes 1 and 2, Core and Profiles: Version 1.1, 22nd February, 2001, (hereinafter “Bluetooth Specification”) describes the principles of Bluetooth device operation and communication protocols. Bluetooth devices are designed to find other Bluetooth devices and access points within their ten meter radio communications range.

The Bluetooth Specification describes the basic security features of the Bluetooth technology in its Chapter 14. The Bluetooth system provides usage protection and information confidentiality at the application layer and at the link layer. In each Bluetooth device and access point, the authentication and encryption routines are implemented in the same way, using the device's address BD_ADDR, two secret keys, and a random number which is different for each new transaction. What is needed in the prior art is a method to customize security features for short range RF devices and access points based on the current context of the mobile device.

In addition to the Bluetooth technology, examples of wireless local area network technology include the IEEE 802.11 Wireless LAN Standard and the HIPERLAN Standard, which operate in the 5 GHz U-NII band. The IEEE 802.11 Wireless LAN Standard is published in three parts as IEEE 802.11-1999; IEEE 802.11a-1999; and IEEE 802.11b-1999, which are available from the IEEE, Inc. web site http://grouper.ieee.org/groups/802/11. An overview of the HIPERLAN Type 2 principles of operation is provided in the Broadband Radio Access Networks (BRAN), HIPERLAN Type 2; System Overview, ETSI TR 101 683 VI.I.1 (2000-02). Another example of wireless local area network technology is Ultra Wideband (UWB) radio, a wireless technology for transmitting digital data over a wide spectrum of frequency bands with very low power. An Ultra Wideband (UWB) standard published by the IEEE 802.15.3a task group is a “classical” direct sequence version of UWB for Personal Area Networking.

What is needed in the prior art is a method to customize security features for short-range mobile wireless devices and access points based on the current context of the mobile device.

SUMMARY OF THE INVENTION

The invention solves the problem of providing customizable, context dependent security features for short range RF devices based on the current context of the device. In accordance with the invention, the mobile device, the wireless access point, and the network server in the network each include security context middleware that responds to the detected location of the mobile device to provide customized security services to the mobile device. The security context middleware enables detecting, authenticating and registering the mobile device and encrypting its communications based on pre-specified security feature descriptions stored in the network server. The system administrator or a system management program can assign particular security features to individual access points in the network. The security features can be pre-specified based on the location of the access point, the identity of the user's mobile device, other characteristics of the user or the user's device, ambient conditions, such as the time of day, and the classification of any services requested by the mobile device.

When a mobile device moves into the communication domain of an access point, its presence is detected by the access point, a basic connection is established between the device and the access point, and the presence of the device is registered at the network server. The network server can then classify any service requested by the mobile device, such as synchronization to applications residing on another server and consider such service request as a factor in establishing an appropriate security feature to apply to the mobile device. For example, if the mobile device has requested synchronization with a confidential email or calendar service to update the mobile device, a high security will be assigned to the wireless connection between the mobile device and the access point.

The network server can then access a security context database to obtain the pre-specified security features corresponding to the location of the access point, the identity of the user's mobile device, other characteristics of the user or the user's device, ambient conditions, such as the time of day, and classification of any service requested by the mobile device. The network server obtains a middleware command from the database corresponding to the pre-specified security feature. The middleware command then is transmitted from the network server to the access point and to the mobile device. The middleware command invokes the particular security processing routine in the middleware of both the mobile device and the access point to implement the pre-specified security feature. The middleware command can also invoke a corresponding security processing routine in the network server when the server needs to participate in providing the security service to the mobile device.

Some of the factors considered by the security context middleware in determining the context of the mobile device include the mobile device's address BD_ADDR, the location of the access point, other available information about the mobile device, and the time of day. Other environmental factors that can also be considered by the security context middleware in determining the context of the mobile device include day of the week, season of the year, temperature, light level, and other ambient characteristics. The security context middleware can also classify any service requested by the mobile device, such as synchronization to applications residing on another server, and consider such service request as a factor in establishing an appropriate security feature to apply to the mobile device.

The network server is also responsible for maintaining additional information for comparing the determined context of the mobile device with threshold values of services that are pre-specified for the mobile device. The network server can automatically synchronize the mobile device with email or calendar services, for example, on another server. The network server can generate triggering events based on the comparison and send notices to the mobile device for suitable services or directly push service messages to the mobile device. In addition, the network server can provide necessary information to third parties for initiating services to the mobile device based on the comparison. Third party services can be provided to the mobile device either through the connected access point or via a separate cellular telephone network connection.

The resulting invention solves the problem of providing context dependent security features for short range RF devices based on the current context of the device.

The invention can be applied to wireless personal area networks employing the Bluetooth Standard, and to wireless local area networks employing the IEEE 802.11 Wireless LAN Standard or the HIPERLAN Standard.

DISCUSSION OF THE PREFERRED EMBODIMENT

FIG. 1A is a network diagram according to an embodiment of the present invention showing a plurality of wireless access points 140, 140A, 140B and 140C. The local area network (LAN) 142 interconnects the access points with the connectivity server 180 which in turn is connected to the security context database 182. The user's wireless device 100 is shown at a first location A near first wireless access point 140A, and then at a later time is shown at a second location B near a second wireless access point 140B. Each respective access point has a corresponding coverage area 150, 150A, 150B, 150C, respectively. Bluetooth wireless devices have typical coverage area of a radius of 10 meters. IEEE 802.11 Wireless LAN devices and HIPERLAN Wireless LAN devices have a typical coverage area with a radius of 100 meters. A user's wireless device 100 in FIG. 1 includes the microbrowser 102, a key pad, and an application program 106. Also included, in the user's wireless device is security context middleware 10, which is shown in greater detail in FIG. 6. Each access point 140, 140A, 140B and 140C includes security context middleware 10′ which is shown in greater detail in FIG. 7. The connectivity server 180 includes a security context middleware 10″ which is shown in greater detail in FIG. 8. The connectivity server 180 further includes the context manager 14. The connectivity server 180 is also connected to the internet 144 which is connected in turn to the WAP protocol gateway 188 which in turn is connected to the GSM access point 186.

In accordance with the invention, the security context middleware 10 stored in a memory of the user's wireless device 100, has a plurality of security process subroutines 602, 604 and 606 of FIG. 6 which are selectable by a security processing middleware command issued by the context manager 14. Similarly, the security context middleware program 10′ in the access points 140, 140A, 140B and 104C, have a plurality of security process subroutines 702, 704 and 706 of FIG. 7, selectable by the security processing middleware command issued by the context manager 14. Similarly, the security context middleware 10″ in the connectivity server 180 has a plurality of security process subroutines 802, 804 and 806 of FIG. 8 which are selectable by the security processing middleware command issued by the context manager 14. Further in accordance with the invention, the context manager program 14 in the connectivity server 180 determines a context for the user's wireless mobile device 100 from a signal received from one of the access points 140, 140A, B, C indicating that the wireless mobile device is wirelessly connected to that access point. The security context database 182 connected to the connectivity server 180 stores security feature data which is accessible by the determined context from the connectivity server 180, to implement a security process. The context manager 14 accesses the stored security feature data in the security context database 182 based on the determined context of the user's wireless device 100 in the vicinity of the access points 140, 140A, 140B or 140C. The context manager 14 then sends the security processing middleware command representing the security feature data to the security context middleware program 10″ in the connectivity server 180, the security context middleware program 10′ in the access point connected to the user's wireless device 100, and to the security context middleware 10 in the user's wireless device 100. The security processing middleware command then invokes the security process in the addressed subroutine in the wireless mobile device, in the access point and in the connectivity server 180.

The security context database 182 and the security middleware commands table 182′ are shown in FIG. 5A. A system administrator or a system control program will initialize the data in the security context database 182 to establish particular security features 294 for each of the access points 140, 140A, 140B and 140C when they are respectively wirelessly connected to the user's device 100. For example, the security context database 182 will establish that the access point 140A, when its wirelessly connected to any user device, as indicated in 284, will have a type 1 security feature 294. The type 1 security feature will then invoke in the security middleware commands table 182′, basic Bluetooth security. The type 1 security processing middleware command will be transmitted by the connectivity server 180 to the security context middleware 10″ in the server 180, to the access point 140A and its security context middleware 10′, and to the user's wireless device 100 which is wirelessly connected to the access point 140A, for the security context middleware 10 in the user's wireless device 100. As can be seen by inspection of the security context database 182 of FIG. 5A, a system administrator has assigned security features 294 to each of the access points 140, 140A, 140B and 140C when they are respectively wirelessly connected to particular user wireless devices. Column 284 of the database 182 indicates which user devices are permitted to be assigned a security feature. Column 286 specifies whether other terminal data is to be required before security features are assigned. Column 288 specifies whether particular time of day intervals are required before security features are assigned. Column 292 specifies one or more services which are provided to the user's wireless device 100 when it is wirelessly connected to each of the respective access 140, 140A, 140B and 140C. As was mentioned before, column 294 indicates the security feature assigned by the system administrator to the respective access points and to the user's wireless device 100 when it is connected to the respective access points. The security middleware commands table 182′ enables the system administrator to programmatically change the security feature assigned to a particular access point and wireless device connected thereto. Five types of security features are shown in the table 182′. Type 1 is a basic Bluetooth security. Type 2 uses an acceptable address list with the specified wireless device addresses. Type 3 requires a link key and 128-bit encryption and a dynamic point-to-point protocol (PPP) user name and password. Type 4 increases the security from type 3 by providing a terminal key and an encrypted link key plus the 128-bit encryption and the dynamic PPP user name/password. Type 5 security feature is a public key infrastructure (PKI) security feature wherein there is a public key encryption of a random link and 128-bit bulk encryption.

FIG. 1B is a network diagram according to an embodiment of the present invention showing a modification in the topology of the network of FIG. 1A where the access points are distributed within an office building 148. The local area network (LAN) 142 connects the access points 140, 140A, 140B and 140C with the connectivity server 180. Several servers are shown connected by means of the LAN 142 to the access points, to provide business related services when signaled by the access points. A company confidential information server 190 and a company confidential information database 191 are connected to the LAN 142. An accounts department server 192 and an accounts department database 193 are connected to the LAN 142. A docking station server 194 and a docking station database 195 are connected to the LAN 142. A room lighting server 196 and a room lighting database 197 are connected to the LAN 142. The office building 148 has a front entrance 152 and a lobby coverage area 150A where is located the access point 140A. Next in the office building 148 is the office coverage area 150 with the access point 140. Next in the office building 148 is the office coverage area 150B with the access point 140B, which is a docking station. Lastly, the office building 148 has a coverage area 150C with the access point 140C which is a cashier terminal. A lighting control 198 is connected from the room lighting server 196 to the lights in the respective coverage areas of the office building 148, as shown in FIG. 1B. When the user's wireless device 100 enters the office building 148 through the front entrance 152, into the lobby coverage area 150A, the access point 140A establishes a wireless connection with the user's wireless device. As the user's wireless device proceeds through the office building 148 to the office 2 coverage area 150B, the mobile wireless device establishes a wireless connection with the access point 140B, for example, when the user places the wireless device 100 into the docking station.

Reference to FIG. 2 illustrates the sequence of operational steps that take place beginning at this point according to an embodiment of the present invention. In the preferred embodiment, the Access Point 140B periodically transmits inquiry packets to discover which mobile devices are in range, and determine the addresses and clocks for the devices. If a mobile device 100 that receives the inquiry packets is in the inquiry scan state, it will then enter the inquiry response state and send an inquiry response 202 to the Access Point 140B. The Access Point 140B can compare the received address with a list of addresses of devices that are authorized to receive services and can proceed to establish a connection with an authorized mobile device. The comparison can also be based on other information about the mobile device 100, such as the class of device (CoD) field, and the list can identify those devices that are to be accepted or alternately blocked from receiving certain types of services. After the inquiry procedure has completed, a connection can be established by the Access Point 140B with a paging procedure using the Bluetooth device address of the mobile device 100. The Access Point 140B having established the connection will automatically be the master of the connection.

In step 200 the user's wireless device sends an inquiry response 202 to the access point 140B and receives a page 204 from the access point. Correspondingly, the access point receives the inquiry response packet from user's device 100. After inquiry and paging signals are exchanged, basic connection is established between the user's wireless device 100 and the access point 140B. At this point, an initial request for services can be sent by the mobile device 100 to the access point 140B, such as requesting synchronization of received email or synchronization of a calendar. A signal is transmitted from the access point 140B over the LAN 142 to the connectivity server 180 where the asynchronous connectionless link (ACL) is validated in step 208. Step 207 can then classify any services requested by the mobile device 100 and pass the classification information to the next step 209 where it is considered as a factor in establishing an appropriate security feature to apply to the mobile device 100.

Then passing to the path 209 the connectivity server 180 accesses the security context database 182 for security features to apply to the connection between the user's wireless device 100 and the access point 140B. This is done in step 210 using the access point address, user's device ID, any required terminal information about the user's device, the time of day and the class of service requested by the mobile device. Referring for a moment to the security context database 182 of FIG. 5A, it is seen that these various factors are considered in the selection of a security feature, such as, specific identities of acceptable mobile wireless devices, other terminal data and time of day. When the corresponding security feature 294 is identified in the database 182, in this case it is a type 3 security feature, the corresponding security processing middleware command is sent on path 211 to the access point 140B. In step 212, the access point 140B implements the accessed security features in the security middleware 702 in the access point. The security processing middleware command is also transmitted over path 213 to the user's device 100 where in step 214 it implements the accessed security features in the security middleware 602 in the user's device 100.

Step 210 in the connectivity server 180 then proceeds to step 215 which generates a link key which is transmitted via the access point 140B to the user's device 100, as step 216 in the subroutine 602 of the security context middleware 10, where it initiates security settings. In the connectivity server 180, step 215 proceeds to step 225 which sets the link key for Bluetooth 128-bit encryption. This information is then provided to the access point 140B the step 222 in the subroutine 702 of the security context middleware 10′, to establish an authenticated and encrypted middleware connection with the user's device. Correspondingly, step 216 in the user's device 100 proceeds to step 218 to establish the authenticated and encrypted middleware connection with the access point over path 220. Step 222 in the access point 140B then proceeds to step 224 where the middleware connection is established and this information is then passed back to the connectivity server 180 step 226 which generates the dynamic point-to-point protocol user name and password for additional access control. The flow then passes to step 228 to forward the PPP user name and password to the access point and the user device. Step 230 of the access point 140B, forwards the PPP user name and password to the user device and also applies it to step 236. In the user's device 100, step 232 establishes the authenticated and encrypted IP connection with the access point and flow passes to step 234. Step 234 and 236 then establish over path 235 an authenticated and encrypted IP connection. Then the connectivity server 180 in step 238 accesses the context database 182 for services available to the user's device using the access point's address, the user's device ID, terminal information, time, and service requests. The network server can automatically synchronize the mobile device with email or calendar services on another server. Reference to FIG. 5A shows that for a connection between the user's device 100 and the access point 140B, services allowed to the user's device include lighting from the lighting server 196 and docking facility services from the docking station server 194 in FIG. 1B.

If the user's device 100 were now to pass to the cashier coverage area 150C in FIG. 1B, a wireless connection is established with the access point 140C, which invokes a different set of security features, as is shown in FIG. 3. Reference to the security context database 182 in FIG. 5A shows that the system administrator has assigned a type 4 security feature to the user's device 100 when it establishes a wireless connection with the access point 140C in the cashier's coverage area 150C. The flow diagram in FIG. 3 illustrates this different implementation of security features according to an embodiment of the present invention. Here it is seen that the subroutine 604 of the security context middleware 10 in the user's wireless device 100 is invoked by command type 4. Further it is seen that the subroutine 704 in the security context middleware 10′ in access point 140C is invoked by the command type 4. Further, it is seen that the subroutine 804 in the security context middleware 10″ is invoked in the connectivity server 180 in response to the command type 4. Steps 200-214 in FIG. 3 are the same as in FIG. 2, except that step 210 has accessed the context security context database 182 and has obtained a type 4 security feature which it distributes as a command type 4 to the access point 140C, the user's device 100 and the security context middleware 10″ in the connectivity server 180. Step 210 passes to step 302 which generates a terminal key which is transmitted via the access point 140C to the user's device 100 step 304 of subroutine 604 of the security context middleware 10, where the terminal key is stored. Step 302 in the connectivity server 180 passes to step 306 which constructs a random link key and encrypts it with a terminal key. The encrypted link key is then transmitted via the access point 140C to step 308 in the user's device 100 where the encrypted link key is opened with the terminal key. Then step 306 in the connectivity server 180 passes to step 310 which sets the link key for Bluetooth 128-bit encryption and this information is then passed to step 312 of the access point 140C. In the user's device 100, step 308 passes to step 314 which establishes an authenticated and encrypted middleware connection with the access point via the path 316. Correspondingly, step 312 of the access point 140C establishes an authenticated and encrypted middleware connection with the user's device. Then flow passes from step 312 to step 318 in the access point 140C where the middleware connection is established and this information is then passed to step 320 of the connectivity server 180 where the step generates a dynamic PPP user name and password for additional access control. Flow then passes to step 322 which forwards the PPP user name and password to the access point 140 and the user's device 100. Step 324 in the access point 140C forwards the PPP user name and password to the user device. Step 326 and the user device 100 establishes authenticated and encrypted IP connection with the access point. The flow then passes to step 234 where the connection is established over the path 235 to the corresponding step 236 in the access point where the connection is established. Then flow passes in connectivity server 180 from step 322 to step 328 to access the context database 182 for services available to the user's device using the access point address, the user's device ID, terminal information and time.

It is seen in FIG. 5A that alternate security features are applied to access point 140B when connected to alternate mobile devices. Additionally, alternate security features can be applied to access point 140 and the mobile device 100 based on class of services requested by the user's mobile device 100. As an example, if the mobile device 100 has requested synchronization with a non-confidential email or calendar service, a low security type 2 security feature is assigned to the wireless connection between the mobile device 100 and the access point 140. Alternately, if the mobile device 100 has requested synchronization with a confidential email or calendar service, a high security type 5 security feature is assigned to the wireless connection between the mobile device 100 and the access point 140. The requested synchronization with the email or calendar service can then be carried out in step 238 of FIGS. 2, 3, or 4 after the appropriate security feature is established for the wireless connection.

FIG. 5B illustrates the security context database 182, wherein the system administrator or a system control program has reprogrammed the access point 140C for public key infrastructure when connected to the user's device 100 according to an embodiment of the present invention. It is seen that a type 5 security feature is specified in the database 182 which corresponds to the public key encryption middleware command shown in the commands table 182′. FIG. 4 illustrates the flow of steps in establishing the public key infrastructure authentication and encryption for the user's wireless device 100 at the access point 140C which have a wireless connection established there between. In an initial provisioning phase, the connectivity server 180 distributes the public/private key pairs with certificates of authority in step 402 to the access point 140C in step 404 and to the user's device 100 in step 406. Then in the later connection phase, steps 200-214 are the same as in the FIGS. 2 and 3 except that step 210 accesses the security context database 182 and obtains the security feature for public key infrastructure and the corresponding command type 5 which it distributes over path 211 to the access point 140C and path 213 to the user's device 100. Then the step 212 of the access point 140C passes to step 408 which sends the access point's public key and its certificate to the user's device. At step 410 in the user's device 100, a random link key is generated and then in step 412, the user's device sends the user's public key and the user's certificate plus the public key encrypted random link key to the access point 140C. Correspondingly, the access point 140C forwards the user's certificate to the server 180 for validation and sends and acknowledgement back to the user in step 414. In the connectivity server 180, the user's certificate is validated in step 416 and the flow passes to step 418 which constructs a random 128-bit PIN for Bluetooth 128-bit encryption and this information is passed to step 420 of the access point 140C. Step 420 in the access point establishes an authenticated and encrypted middleware connection with the user's device. Step 422 in the user's device establishes the authenticated and encrypted middleware connection with the access point 140C over path 424. Flow then passes from step 422 to 426 to establish an authenticated and encrypted IP connection with the access point 140C over path 430 and correspondingly the access point establishes the authenticated and encrypted connection with the user's device. This information is then passed to step 238 in the connectivity server 180 where the security context database 182 is accessed for services available to user's device using the access point address, the user's device ID, terminal information, time of day, and services requested.

FIG. 1C shows an alternate embodiment for the network of FIGS. 1A and 1B, wherein a GSM cellular telephone communication subsystem is included in the wireless mobile device 100. This enables communication between the user's wireless device 100 and third party services server 190 for providing service to the wireless device via the cellular telephone communication's subsystem. Communications is maintained over the internet 144 via the WAP protocol gateway 188 to the GSM access point 186 which communicates wirelessly with the GSM antenna 105 of the user's wireless device 100.

FIG. 1C further shows a barcode reader 141 connected by means of Bluetooth communications software 143 and a Bluetooth RF link to the Bluetooth access point 140A to enable control and use of the barcode reader 141 from the user's mobile wireless device 100. As an example, the application program 106 in the wireless mobile device 100 is programmed to control and use the barcode reader 141 to read a barcode of an article, such as a universal product code (UPC), and to have the value read from the UPC forwarded via the access point 140A to the application program 181 in the connectivity server 180. In order to accomplish this example, application program 106 invokes the middleware 10 in the user's wireless device 100, the middleware 10′ in the access point 140A, and the middleware 10″ in the connectivity server 180. Appropriate context and security processes are carried out by the access point 140A and connectivity server 180, as discussed above, to authenticate the user's device 100 and the barcode reader 141 and establish their respective secure connections with the access point 140A. After secure connections are established between the access point 140A and the user's device 100 and between the access point 140A and the barcode reader 141, the wireless mobile device 100 can control the barcode reader 141 to read a barcode of an article and forward the value read from the UPC via the access point 140A to the application program 181 in the connectivity server 180. This feature of the invention to enable the user's mobile device to control and use a barcode reader can be extended to the control and use of other types of devices. For example, Bluetooth-enabled portable measurement devices can be controlled and used by an application program in the user's mobile device, to send their measurements to a server via distributed access points. An example is a Bluetooth-enabled portable air flow monitor to measure the air circulation in an office building and upload the measurements to a server via access points distributed around the office building.

A Bluetooth wireless communications interface 918 wirelessly interfaces with the mobile wireless device 100. A communications program 920 establishes a wireless connection with the mobile device 100 and also provides context information to the server 180 over the LAN 142. Also shown is the middleware program 10′.

FIG. 9 also shows some of the components of the connectivity server 180, which includes the computer 922 and the memory 924. The context manager program 14 determines a context for the wireless mobile device 100. The database 182 stores security feature data. The context manager 14 accesses the stored security feature data based on the determined context of the mobile device 100 and issues a command representing the security feature data. Also shown is the middleware program 10″ and the application program 181.

FIG. 1D is a network diagram showing another modification in the topology of the network of FIG. 1A, in which the access points 140A′ and 140B′ are mobile and include a GPS position locator to establish their current locations. A GSM cellular telephone subsystem in each access point enables it to communicate with the connectivity server 180 over a wireless wide area network 142′. The a cellular telephone communications subsystem can enable a third party to provide service to the user's wireless mobile device 100 via the wireless wide area network 142′.

In an alternate embodiment of the invention, at least some of the functions of the connectivity server 180 and context manager 14 can be contained within the access points 140A and 140B. Similarly, at least some of the functions of the security context database 182 can be contained within the access points 140A and 140B.
