发明名称 System and method for generating a digital certificate
摘要 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.
