SYSTEM AND METHOD FOR CREATING ELECTRONIC SIGNATURES

摘要

A system and method for generating electronic signatures is provided. A first server receives a digital representation of a document or other content from a workstation. The first server authenticates the identity of the entity seeking to electronically sign the document or other content and generates a unique first signature statement based on the contents of the document and the identity of the signing entity. The first server adds the unique signature statement to a sequence of such statements and at some time thereafter calculates a representation of the sequence of statements by performing a hash function on the sequence. The first server sends the unique representation to at least two second servers, which generate a verifiable cryptographic signature corresponding to the unique representation, and transmits the signature to the first server. Lastly, the first server generates an electronic signature based on the unique signature statement, the sequence of unique signature statements, and the cryptographic signature from the at least two second servers.
