Electronic signature verification method, terminal equipment and computer readable medium

Abstract

The embodiment of the invention discloses an electronic signature verification method, terminal equipment and a computer readable medium. The method is applied to the terminal equipment which containsa finger biological information sensor in a touch screen. The method comprises the following steps that: through the touch screen, collecting an input signature trajectory, and while the signature trajectory is collected, collecting a finger contact feature corresponding to the signature trajectory through the finger biological information sensor; verifying whether the signature trajectory is matched with a pre-stored signature trajectory or not; if the signature trajectory is matched with the pre-stored signature trajectory, verifying whether the finger contact feature corresponding to the signature trajectory is matched with a pre-stored finger contact feature corresponding to the pre-stored signature trajectory or not; and if the finger contact feature corresponding to the signature trajectory is matched with the pre-stored finger contact feature corresponding to the pre-stored signature trajectory, determining the signature trajectory passes electronic signature verification. By use of the electronic signature verification method of the embodiment of the invention, the use safety of the electronic signature can be improved.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to an electronic signature verification method, a terminal device and a computer-readable medium. Background technique [0002] With the continuous development of the economy and society, especially with the development of e-commerce, the use of electronic documents is becoming more and more extensive. Therefore, many terminal equipment manufacturers have launched the original handwriting signature function on the terminal equipment side according to the office needs of business people. When users When you need to sign your own name on documents or materials, you only need to enter the electronic signature in the electronic document of the terminal device. At the same time, in many occasions (such as when paying through the terminal device), it is necessary to use the electronic signature for identity authentication. [0003] However, the current electronic signatures are ...
