Problems solved by technology

[0004] It can be seen that the current implementation of handwritten signature verification is only to collect and compare the movement trajectory of the user's handwritten signature. Illegal users often easily imitate the movement trajectory, so the security is low

Embodiment Construction

[0075] A kind of method that realizes handwritten signature verification is proposed in one embodiment of the present invention, see figure 1 , the method includes:

[0076] Step 101: Set relative data processing algorithm and matching degree algorithm.

[0077] Here, the relative data processing algorithm is used to perform relative numerical processing on the data of the user's handwritten signature, so as to effectively avoid problems such as the signing user cannot guarantee that the starting position of each signature and the size of the signature cannot be kept consistent, avoid interference from human factors, and ensure The signature data used for authentication is more accurate and effective.

[0078] The matching degree algorithm is used to give specific matching rules based on the data of the user's handwritten signature.

[0079] Step 102: Obtain the first main data and the first auxiliary data input on the touch screen of the electronic device when the first use...

Abstract

The invention provides a method and device for achieving handwritten signature verification. The method includes the following steps of setting a relative data processing algorithm and a matching degree algorithm, obtaining first master data and first auxiliary data input to a touch screen of electronic equipment when a first user handwrites a signature, processing and storing the first master data and the first auxiliary data according to the relative data processing algorithm, obtaining second master data and second auxiliary data input to the touch screen of the electronic equipment when the first user handwrites the signature again, processing the second master data and the second auxiliary data according to the relative data processing algorithm, and conducting first user signature verification according to the matching degree algorithm on the basis of the processed first master data, the processed second main data, the processed first auxiliary data and the processed second auxiliary data, wherein the master data comprise the movement track of the signature. The method and device for achieving handwritten signature verification can improve handwritten signature verification safety.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to a method and device for realizing handwritten signature verification. Background technique [0002] With the development of science and technology, the popularity of computers and networks has made people's interactions more frequent and more convenient, but the accompanying security problems have become more and more prominent. Therefore, how to accurately identify a person's identity and protect information security is a key issue that must be solved in today's information age. Currently, handwritten signatures are widely used in the field of information security. Compared with other identity authentication technologies, handwritten signature authentication technology has obvious advantages: compared with other biometric identifications such as fingerprints and voices, its cost is lower, it is easy to use, it does not require professional and complicated samplin...
