User authentication method and device

Abstract

The application relates to a computer technology, and discloses a user authentication method and device aiming at ensuring the accuracy of authentication while reducing the operation complexity of a verification process. The method comprises the following step: a user authentication device real-timely collects and stores a plurality of user behavior data of a first user through a plurality of sensors, separately generates corresponding user characteristic information based on two segments of user behavior data with different storage time, and then matches the two pieces of user characteristic information, and judges that the user is successfully authenticated when a successful match is determined. Thereby, according to a method for authenticating the user by using the user characteristic information extracted based on the user behavior data, the information leakage can be effectively avoided, the difficulty of password cracking can be increased, the possibility of stealing or copying passwords by third parties can be effectively reduced, the accuracy of authentication can be ensured, and the security of the system can be enhanced.

Description

technical field [0001] This application relates to computer technology, in particular to a method and device for user identity verification. Background technique [0002] With the rapid development of the times, smart devices, especially handheld smart devices (such as: laptops, tablets, mobile phones or other mobile terminals) are becoming more and more popular. These smart devices usually have built-in various sensors (such as: acceleration sensor, gyroscope sensor, gravity sensor, etc.). [0003] On the other hand, in order to meet the increasingly rich usage needs of users, various application service providers have developed a large number of application software to carry the core business of customers, which provides great convenience for users' life. Human beings have begun to rely more and more on smart devices, such as recharge, transfer and other operations related to vital interests. [0004] At the same time, there are also a lot of hidden dangers in the login ...

Problems solved by technology

[0006] The second hidden danger is: Hackers steal users' account passwords, log in to specific application software as users, spy on other people's privacy, steal money or virtual property, etc.

[0015] For CAPTCHA technology, there are already many ways to crack it, for example, machine automatic recognition of verification codes, human flesh distributed verification code recognition technology, network coding technology, etc. In order to cope with these cracking methods, some verification codes add many redundant elements, Even the human eye is difficult to identify, which seriously affects the user experience
