SYSTEM AND METHOD FOR GENERATING A DIGITAL CERTIFICATE
First Claim
1. A method for evaluating a digital certificate comprising at least a sequence value and a first composite digital value, comprising the steps of:
- providing for generating a second composite digital value by applying a deterministic function to at least a subset of the digital records stored in a repository;
providing for generating an interval digital value, wherein the interval digital value is based upon the first and second composite digital values; and
, providing for determining from the interval digital value whether the first composite digital value accurately reflects at least a subset of the digital records in the repository.

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.
