Security verification code generation method and system based on track drawing interaction and medium

Abstract

The invention discloses a security verification code generation method and system based on track drawing interaction and a medium. The method comprises the steps of formulating a security rule; enabling the client to request the server for identity authentication; enabling the server to generate a data token, a verification code question and a picture, and storing the related information into a database; adding the interference to the generated picture, and transmitting the picture to a client; enabling the client to recover and display the disordered verification code picture; recording track information drawn by a user, encrypting track information data and a data token, and transmitting the data and the data token to a server; and enabling the server side to judge the track information and return a result to the client side. According to the invention, the transmitted data is encrypted using an RC4 encryption algorithm; when the headless browser is detected in the JavaScript, the verification is rejected; the machine behavior is judged by using an algorithm for extracting human drawing trajectory feature design, the safety and correctness are improved by the technical means, and the cracking of an OCR picture recognition technology and the behavior of generating a trajectory by machine simulation can be effectively prevented.

Description

technical field [0001] The invention belongs to the technical field of verification code security, and in particular relates to a method, system and medium for generating a security verification code based on trajectory drawing interaction. Background technique [0002] In the process of user authentication, there are a large number of security verification operations mainly in the form of verification codes. However, most verification codes currently on the market have relatively easy cracking methods, and their security performance is low. However, a small number of verification codes with high security blindly increase the difficulty of recognition, which is difficult not only for machines but also for humans, and the user experience is extremely poor. [0003] At present, there are several mainstream behavior verification codes on the market, such as text input verification code and text selection verification code. Although these two types of verification codes are sim...

Problems solved by technology

In order to increase the difficulty of cracking, some verification codes blindly add noise to the background image. Although the difficulty of image recognition increases, it also increases the difficulty of human recognition.
