Abstract

A device verification method includes the steps of providing a device including a memory and a print pattern generator communicatively coupled to the memory, the print pattern generator generating image data based at least in part on a first value actually stored in a first memory location in the memory; printing the image data to produce a printed verification pattern; scanning the printed verification pattern to generate a verification value; reading a memorized value purportedly stored in the first memory location of the memory; comparing the memorized value with the verification value; and evaluating the device based on a result of the comparing step.

Claims

AMENDED CLAIMS
[Received by the International Bureau on 18 August 2004 (18.08.04): original claims 1-43 replaced by amended claims 1,3 and 4; claims 2 and 5-43 unchanged ( 2 pages)]
! . A device verification method, comprising the steps of: providing a device including a memory and a print pattern generator communicatively coupled to said memory, said print pattern generator generating image data based at least in part on a first value actually stored in a first memory location in said memory; printing said image data to produce a printed verification pattern; scanning said printed verification pattern to generate a verification value; attempting to read a memorized value purportedly stored in said first memory location of said memory, wherein if an intrusion apparatus is present, then a false memory value, stored in a memory associated with said intrusion apparatus, is read; comparing said memorized value with said verification value; and evaluating said device based on a result of said comparing step.
2. The method of claim 1, wherein said evaluating step comprises the step of determining whether said memorized value corresponds to said verification value.
3. The method of claim 2, wherein if said memorized value corresponds to said verification value, then said device is verified as valid.
4. The method of claim 2, wherein if said memorized value does not correspond to said verification value, then said method comprising the further step of performing a verification failure sequence for said device.
5. The method of claim 1 , wherein said print pattern generator generates said image data hy modifying received print data using said first value actually stored in said memory.
6. The method of claim 1, wherein said device is a printhcad.
7. The method of claim 6, wherein said memory and said print pattern generator are formed integral with said printhead.
22
8. The mctliod of claim 1, wherein said device is a circuit.
