Patents

A system and method for authenticating records. Certification information may be encoded in graphical form. This graphical form, or design, may be referred to as an “Indicia.” The record at issue may be printed out by a computer or stored electronically and bear on it an indicia that relates to the authenticity of the document. The indicia (and record) may then be scanned and interpreted by the computer to authenticate the record.

Claims

1. A method for providing security with respect to who provided digital data at what time, said method comprising the steps of:

performing a serially chained certification process including:

a) forming a first interval certification at a first server including the server's identification, the start time of an interval chain in Coordinated Universal Time, the start time of the interval in Coordinated Universal Time, the stop time of the interval, a public key for the interval, a digital signature for the interval, signed by a previous interval's private key, and a digital signature for the interval, signed by the interval's private key;

b) upon expiration of the first interval, destroying its private key;

c) continuing steps (a) and (b) for second, third, and following intervals so that intervals are cross-chained with other servers to form a widely witnessed, temporal web of signed intervals of time; and
encoding certification information in graphical form to form an indicia that relates to the authenticity of the document.

2. The method of claim 1 further comprising the step of:

decoding the indicia to authenticate a document.
