METHOD FOR SIGNING ELECTRONIC DOCUMENTS WITH AN ANALOG-DIGITAL SIGNATURE WITH ADDITIONAL VERIFICATION

摘要

There is disclosed a method of signing an electronic document using an Analog-to-Digital (AD) signature. The method is executable at a server. The method comprises: receiving, from an electronic device, via an encrypted connection of a communication network a signature generation request file, the signature generation request file having been generated by the electronic device by executing: generating a private key; receiving the electronic document to be signed; receiving an Analog-to-Digital (AD) information associated with a user of the electronic device; generating a first control sum based on the electronic document and a second control sum based the AD information associated with the user; generating a single numeric sequence based on the first control sum and the second control sum; encrypting the single numeric sequence using the private key to generate a digital signature; generating the signature confirmation file, the signature generation request file containing at least: an electronic address associated with the user, the electronic document to be signed, the AD information associated with the user, and the digital signature; generating a final signature confirmation file; the final signature confirmation file including a hyperlink to the electronic document to be signed and to the AD information associated with the user, both the electronic document to be signed and the AD information associated with the user accessible via the server; transmitting the final signature confirmation file to the electronic address associated with the user; receiving, from the user, a confirmation response; in response to the conformation response, transmitting, to the electronic address associated with the user, a file containing the digital signature.

1. A method of signing an electronic document using an Analog-to-Digital (AD) signature, the method executable at a server, the method comprising:
receiving, from an electronic device, via an encrypted connection of a communication network a signature generation request file, the signature generation request file having been generated by the electronic device by executing:
generating a private key;receiving the electronic document to be signed;receiving an Analog-to-Digital (AD) information associated with a user of the electronic device;generating a first control sum based on the electronic document and a second control sum based the AD information associated with the user;generating a single numeric sequence based on the first control sum and the second control sum;encrypting the single numeric sequence using the private key to generate a digital signature;generating the signature generation request file, the signature generation request file containing at least: an electronic address associated with the user, the electronic document to be signed, the AD information associated with the user, and the digital signature; generating a final signature confirmation file; the final signature confirmation file including a hyperlink to the electronic document to be signed and to the AD information associated with the user, both the electronic document to be signed and the AD information associated with the user accessible via the server; transmitting the final signature confirmation file to the electronic address associated with the user; receiving, from the user, a confirmation response; in response to the conformation response, transmitting, to the electronic address associated with the user, a file containing the digital signature.
