Generation and verification method, electronic device and storage medium of a verification code

Abstract

Embodiments of the present invention provide a verification code generation, verification method, electronic device, and storage medium. The generation method includes: receiving a request sent by a terminal, and generating at least three random numbers; generating element expressions; each element expression One side is a mathematical operation expression composed of two different graphic symbol elements and mathematical operators, and the other side is a combined numerical symbol element corresponding to the mathematical operation result of the mathematical operation expression; according to the element expression generating a verification code, and controlling the terminal to display the verification code. The method, the electronic device and the storage medium provided by the embodiment of the present invention improve the security of the user account and the response speed of the server.

Description

technical field [0001] The invention relates to the technical field of data security, in particular to a verification code generation and verification method, electronic equipment and a storage medium. Background technique [0002] In order to ensure the security of the user account, when the user enters the account number and password to log in to a system, it is usually necessary to generate a verification code. [0003] There are many forms of verification codes generated by existing technologies, such as random combinations of numbers and letters, pictures containing specific text or specific elements, four arithmetic operations that randomly generate two elements, sliding verification codes, etc. The above-mentioned verification codes are all verified based on intuitive vision or simple calculations. There are the following problems: 1. The verification codes are easily recognized by machines and thus cracked. Malicious behaviors such as automatic batch registration can...

Problems solved by technology

The above-mentioned verification codes are verified based on intuitive vision or simple calculations, and there are the following problems: 1. The verification codes are easily recognized by machines and thus cracked, and cannot effectively prevent malicious behaviors such as automatic batch registration

2. Each type of verification code has a specific format. For example, the digital verification code is of fixed length. Based on the above problems, it can be determined that the existing technology has brought security risks to the user's account security.
