Embodiment Construction

[0074] In order to reduce the operation complexity of the verification process and ensure the verification accuracy, in the embodiment of this application, various sensors are used to collect user behavior data in real time in advance, and then the user identity verification device uses a specific algorithm to collect The various collected user behavior data are integrated into the benchmark user characteristic information, so that when the user triggers the user identity verification process, the user identity verification device can generate current user characteristic information based on the user behavior data collected in the second period, and pass the current According to the matching degree of the user characteristic information and the benchmark user characteristic information, it is judged whether the user authentication is successful.

[0075] Preferred embodiments of the present application will be described in further detail below in conjunction with the accompanyi...

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 ...
