Method and device for recognizing user behavior based on prediction model

Abstract

Embodiments of the present application disclose a user behavior identification method and apparatus based on a prediction model. The method includes: first user operation data for triggering a start-up target service is obtained, and first user identification information associated with the first user operation data is determined; based on user behavior recognition model of the target service, a target us behavior class correspond to that first user operation data and the first user identification information is determined, the user behavior identification model is obtained by training sampledata for starting the target service, and the sample data includes at least the first user behavior sample data and the second user behavior sample data; the user authentication of the target serviceis completed according to the target user behavior category and the target service is started, or the user authentication of the target service is disconnected. By adopting the embodiment of the present application, the user behavior category can be determined based on the regression algorithm, the identification accuracy rate of the user behavior category starting the target service is improved,and the user data security of the target service is improved.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a prediction model-based user behavior recognition method and device. Background technique [0002] At present, as the functions of terminal equipment are becoming more and more perfect, users can handle various services through terminal equipment, which makes the relationship between terminal equipment and users' daily life increasingly close. In order to ensure the security of various businesses handled by the user through the terminal device, the terminal device can perform user authentication based on the user behavior analysis when the user handles the business when the user handles various businesses, including the user's operations and / or The information provided by the user when handling business is analyzed for user behavior to realize user authentication, and then the corresponding business can be started only when the user passes the authenticati...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, user authentication when a user handles business on each terminal device is generally a stand-alone machine that independently conducts data analysis and calculation of user behavior. Due to the limitations of factors such as the hardware conditions of the stand-alone terminal device, the stand-alone machine independently performs user behavior analysis. Data processing efficiency is low, user behavior recognition efficiency is low, and the scope of application is small, resulting in low security of user authentication for business
