Dynamic verification code generation method

Abstract

The invention belongs to the technical field of safety verification, and discloses a dynamic verification code generation method. The method comprises the steps that whether a dynamic verification code generation request exists or not is detected in real time, If yes, the current generation request is received and analyzed; judging whether the current generation request comprises a human face image or not, If so, obtaining the current human face image; obtaining a face area in the current face image and extracting a plurality of feature points; obtaining an initial password according to the plurality of feature points; obtaining request time and a first dynamic random code in the current generation request, and then performing encryption calculation on the initial password, the request time and the first dynamic random code to obtain a dynamic verification code. According to the invention, the targeted dynamic verification code is generated according to the different face areas in eachgeneration request, so that the dynamic verification code is prevented from being easily cracked, the information safety problem is further avoided, the safety requirements of the verification process with higher information safety requirements or privacy safety requirements can be met, and the method is suitable for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of security verification, and in particular relates to a method for generating a dynamic verification code. Background technique [0002] Identity verification is one of the basic issues in social life. The identity verification system not only has great application prospects in family life, personal entertainment, and enterprise applications, but also plays an important role in national security, judicial criminal investigation, and personal safety. At present, identity verification adopts traditional technologies based on carrying objects (such as IC cards, keys, etc.) or knowledge (such as passwords, passwords, etc.), and also uses computer automatic identification technology based on dynamic verification codes; among them, dynamic verification codes are currently distinguished. Whether the user is a computer or a public fully automatic program, it can effectively prevent hackers from making continuous lo...

Problems solved by technology

[0004] 1) The current dynamic verification code is usually garbled code directly generated by the dynamic token, which cannot be generated for different users. The password generation process of the dynamic token is easy to be cracked, resulting in low security of the verification process. The security requirements of the verification process for information confidentiality requirements or privacy confidentiality requirements cannot be met;

[0005] 2) Part of the current dynamic verification code is to complete the verification process on the server side by directly sending the user authentication information of the user terminal that initiated the verification request. Although the problem that the verification code is easy to be cracked is solved, the user terminal stored in the user terminal There is a risk of leakage of authentication information, and the problems of practicality and security cannot be considered
