TERMINAL AUTHENTICATION METHOD AND DEVICE THEREOF

摘要

A terminal authentication method and a device are provided by the present invention. The method includes the following steps: a terminal senses pressure information through a touch screen; said pressure information includes a pressing strength value of a pressing contact point when the user presses the touch screen; the terminal compares the sensed pressure information, used as an authentication password, with an authentication password stored in the terminal; if said sensed pressure information matches with said stored authentication password, the terminal determines that the password authentication is passed; otherwise the terminal determines that the password authentication is not passed. The method and the device of the present invention perform an authentication on the terminal on the premise of high security and convenient authentication.
