Identity continuous authentication method based on touch screen sliding behavior characteristics

Abstract

The invention discloses a continuous identity authentication method based on touch screen slip behavior characteristics. The method comprises the following steps: analyzing touch screen slip operation behaviors generated when a user operates touch screen equipment; classifying touch screen slip operations into four operation modes according to touch screen slip directions, extracting behavior characteristics under each operation mode, establishing a user identity model under each operation mode based on the behavior characteristics, and performing continuous authentication on the identity of the user of the touch screen equipment by use of a window average method. According to the method, the touch screen slip behaviors do not need to be memorized or carried, behavior data collection can be finished in a daily touch screen equipment use process of the user without cooperation of the user, and non-invasive initiative identity authentication can be realized; in addition, a method of respectively performing modeling and window authentication on different types of touch screen operations is adopted, so that the stability of the authentication model can be ensured, the touch screen behavior characteristics of the user can be better embodied, and the robustness and fault tolerance of continuous identity authentication are obviously improved.

Description

technical field [0001] The invention relates to the safety protection technology of touch screen equipment, in particular to a security identity authentication method for touch screen equipment users. Background technique [0002] With the advancement of social informatization and intelligence, touch-screen devices (such as smart phones and tablet computers) have penetrated into all aspects of people's lives, and more and more personal information (such as text messages, emails, pictures, etc.) and Sensitive information (such as bank account numbers, office data, etc.) is stored in touch-screen devices. In addition, the increasing popularity of business applications on touch-screen devices and the frequent occurrence of privacy information leakage incidents have gradually brought the security protection of touch-screen devices into the public's field of vision. [0003] Existing identity authentication methods for touch screen devices mainly include passwords, Jiugongge pat...

Problems solved by technology

However, the first two methods are vulnerable to observation attacks and guessing attacks, so that the attacker can steal the unlocking method; the fingerprint authentication method requires special hardware support; and these three methods can only ) for one-time protection, once the touch screen device is invaded, it will completely lose its resistance
