Signature method and device

摘要

A method for signing a document to be transmitted between two correspondents, i.e. a sender and an addressee, including recording the sender and the addressee of the document for the allocation of a digital identity thereto; authorizing by the addressee a correspondence with the sender; ciphering the document; indicating to the addressee that the document is available; detecting an access to the document by the addressee; generating an electronic report indicating the delivery of the document, the document-delivery electronic report including a set of data associated with the transmission of the document to the addressee, the set including identification of elements concerning the addressee authentication, the sealing of the document, the access to the document by the addressee and the time-stamping of the access to the document by the addressee; and electronically signing, by a reliable third-party using the private key thereof, the document-delivery electronic report.

主权项

1. A computing system for managing legal signatures of electronic documents, the computing system comprising:
a processor coupled to a memory device, the processor and memory device configured to implement: a module for recording by a trusted third party of digital identities of users of said system and of electronic-correspondence conventions whereby said users mandate a documentary correspondence operator to administer a proof of legal signature; a module for on-line strong authentication by said trusted third party of the digital identity of a user, wherein said strong authentication is provided by real-time validation by the trusted third party of a one-time password received by the user on a second terminal on a second network, and entered by said user in a first terminal connected to a first network; a module for sending by the user of a validation signal for validating contents of an electronic document, the validation signal generated in response to the user providing in real-time of the one-time password received by the user on the second terminal on the second network and entered by the user on the first terminal connected to the first network; and a module for transmitting a confirmation signal by at least one of said correspondence operator and said trusted third party of said validation signal; wherein: the module for sending by the user of the validation signal comprises a sub-module for interpreting a command input by the user on the first terminal while the user visualizes the content of the electronic document in a non-modifiable format on said first terminal; and a record of the validation signal and the confirmation signal is sealed and stored by the computing system.
