Electronic signature verification method, verification server and user terminal

Abstract

The invention discloses an electronic signature verification method, a verification server and a user terminal. The electronic signature verification method comprises steps of receiving a hand-written signature request carrying personal identity information which is transmitted by a user targeting one matter through the verification server, enabling the user terminal to obtain a hand-written signature interface, enabling the user to provide a corresponding hand-written signature targeting the matter based on the hand-written interface, receiving the hand-written signature which targets the matter and is transmitted by the user terminal and data correlated to personal identity information, extracting a stored verification sample of the hand-written signature correlated to the personal identity information, calculating similarity between the hand-written signature and the extracted verification sample, if the calculated similarity is greater than a first preset threshold value, passing the hand-written signature of the user which targets the matter, or, if the calculated similarity is smaller than or equal to the first preset threshold value, refusing the hand-written signature of the user which targets the matter. The electronic signature verification method, the verification server and the user terminal can automatically verify electronic signatures.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to an electronic signature verification method, a verification server and a user terminal. Background technique [0002] With the continuous development of science and technology and the popularity of smart terminals, more and more people will rely on smart terminals for their work and life, so as to improve work efficiency and the convenience of work and life, and bring people easy and convenient experience. For example, in many fields that require user signatures, most units use electronic signatures to complete signatures, that is, electronic signatures are used on smart terminals to replace the traditional handwritten signatures on paper. [0003] An electronic signature is not a digital image of a written signature. It is similar to a handwritten signature or an electronic seal. It is an electronic signature of an electronic document through cryptographic techn...

Problems solved by technology

In the actual electronic signature process, there are usually cases where the image or text signed by the user is not the required target text. The existing processing method is to verify the electronic signature by manual review. This verification method time-consuming, waste of resources
