Verification method, terminal and server for electronic signature

Abstract

The present invention provides a method for verifying an electronic signature, including: step 102, when the first terminal receives the electronic signature input on the touch input device, it records the graphic information of the electronic signature, and records the electronic signature on the touch input device during the signing process. Generated pressure information; step 104, send the pressure information to the server and send the graphic information and pressure information of the electronic signature to the second terminal; step 106, when verifying the electronic signature on the second terminal, the second terminal sends a verification message to the server Request, and by verifying the graphic information and pressure information of the electronic signature, to determine the authenticity of the electronic signature. Correspondingly, the present invention also provides a terminal and a server. Through the technical scheme of the invention, the authenticity of the electronic signature can be checked, the security of the electronic signature can be improved, the signature information can be prevented from being falsified, and unnecessary losses to users can be avoided.

Description

technical field [0001] The invention relates to the field of electronic information verification, in particular to a verification method for electronic signatures, a terminal and a server. Background technique [0002] The development of e-commerce has made the application of electronic signatures more and more extensive. Users can write signatures directly on devices with touch screens. For example, many mobile phones or smart terminals have touch screen functions, and then users send them to The other party confirms the electronic signature, but due to the handwritten signature on the touch screen of the mobile phone, the handwriting is easy to be imitated, and the electronic signature file is also easy to be copied. Once deceived, the user will suffer huge losses; at the same time, for the authentication of some e-commerce transactions, There are also relatively large loopholes. This kind of security problem is an important issue that currently plagues users and hinders t...
