SYSTEM AND METHOD FOR GENERATING A DIGITAL CERTIFICATE
First Claim
1. A digital certificate comprising:
- a sequence value, wherein the sequence value represents the number of digital records stored in a repository of digital records at a particular time; and
, an interval digital value, wherein the interval digital value is a component of a composite digital value generated by the application of a deterministic function to at least a subset of the digital records stored in the repository at a particular time.

Abstract
A system and method for generating a digital certificate is provided wherein a new digital record is received and is assigned a sequence value. A first composite digital value is generated by applying a first deterministic function to the digital records stored in a repository. The sequence value and first composite digital value are included in a first certificate. After the digital record is added to the repository, a second composite digital value is generated by applying a second deterministic function to the digital records in the repository. This second composite digital value, and a composite sequence value, are published. An interval digital value which is based upon the first and second composite digital values, and the sequence value, are included in a second certificate which thus verifies the authenticity and sequence value of the digital record.
