Abstract:

A system for authenticating records without reliance upon a trusted third party. A first server provides a sequential series of certifications associated with discreet, non-overlapping time Intervals. The server can provide selected information to a second server which, in turn, incorporates the request and associated information in a cross-certification. The cross-certification is then provided to more other servers. Accordingly, a “chain-mail” of certifications among a variety of servers is provided. The system thus provides effective protection against a breach of security in any one server, resulting in increased reliability in the authentication of records.
