METHOD FOR GENERATING AN ELECTRONIC SIGNATURE LINKED TO AN AUTHENTIC ACT AND AUTHENTICATION METHOD

摘要

The invention concerns a method for generating a digital signature related to an electronically written document, so that it fulfils the legal requirements with respect to electronic data, in like manner as a written signature on paper, and that it constitutes evidence of the deliberate will of the engagement. The inventive method consists in, simultaneously with the identification of the signatory by a device provided therefor, generating spherical co-ordinates to form points (A, B, C and P) whereof the dimensional value is derived from the conversion of identification data, of the identity and the set of characters and codes of services constituting the electronically written document. A certifying third party identifies and authenticates the document related to the signature while preserving confidentiality of its contents and its irreversibility, it archives the data of the original geometric figure capable of physical represented in three dimensions, for example in the form of a sphere (S) and a polyhedron. The invention is applicable to any executed document, requiring authenticity, through modern communication means.
