Abstract

A method for screen unlocking of a terminal based on fingerprint identification and a terminal are provided. User operation instruction on a designated unlocking area of the terminal is acquired. Press interrupt request is initiated when a strength value of a touch operation corresponding to the user operation instruction is greater than preset strength threshold. Fingerprint data on the designated unlocking area are collected while waiting for response to the press interrupt request during a waiting time period from initiation of the press interrupt request to respond to the press interrupt request. The fingerprint data are compared with fingerprint verification data pre-stored in an external storage space of the terminal during the waiting time period. A screen interface of the terminal is enabled and the terminal screen is lit up when a response instruction of the press interrupt request is received, when fingerprint data and fingerprint verification data are matched.
