Abstract
A file signing and confirming method based on client screen video fully uses the video capability of intelligent equipment, when a party needs to sign an electronic file, a content page of the file to be signed and a field face video of the party are enabled to synchronously appear on a screen of the equipment through a technical system, the whole operation process of the party on the file is recorded in real time through a screen recording method, and meanwhile, the signing and confirming of the electronic file with high anti-repudiation performance is completed through a human-computer interaction random authentication technology. The invention does not need to rely on intermediate media such as digital certificates and the like, and the signing confirmation is directly completed by the principal on site; the whole process of video screen recording ensures the real signing process of the signer, and has high-strength resistance; the random authentication adopted by the signing confirmation is highly associated with the content of the file, so that the electronic file is effectively prevented from being maliciously replaced.
Description
Technical Field
The invention relates to the field of electronic document signing, in particular to a method for realizing reliable and anti-repudiation signing confirmation of an electronic file under the condition of no third-party digital certificate authentication, and specifically relates to a file signing confirmation method based on a client screen video.
Background
The common signing of the electronic document is widely established on the premise of having similar Ukey or other digital certificate intermediate media and random code verification, the digital certificate is obtained by carrying out identity authentication on a user, when the user needs to sign, the user is signed by the certificate, or the identity of the user is verified by the random code, and the correct verification code is input to represent the signing completion; whether the digital certificate or the verification code is adopted, the signature behavior is separated from the entity of the user, all related sources need to be established in the reliability degree when the digital certificate is authenticated and issued, and the user only controls the private key of the certificate, only under the condition that the user performs safety management and only control on the private key, the signature is technically presumed to be completed only by the user, and for the short message verification code mode, the short message verification code mode is established on the basis of absolute trust of a short message sending and a verifier, and in fact, the establishment of the trust is not difficult.
How to make the signing behavior of the electronic document not depend on intermediate media such as a digital certificate or a short message verification code and the like is very practical, and the method is just like paper signature in a physical environment, and has great practical significance for directly finishing reliable and repudiation-resistant document confirmation.
Disclosure of Invention
The invention aims to solve the problems, provides a file signing and confirming method based on client screen video, fully uses the video capability of intelligent equipment, enables a file content page to be signed and a field facial video of a party to be synchronously displayed on an equipment screen through a technical system when the party needs to sign a certain electronic file, records the whole operation process of the party on the file in real time through a screen recording method, and completes highly repudiation-resistant signing and confirming of the electronic file by using a man-machine interaction random authentication technology.
The technical scheme of the invention is as follows:
the invention provides a file signing and confirming method based on a client screen video, which comprises the following steps:
