Abstract

The invention discloses an unlocking method and an unlocking device for a touch screen of terminal equipment, and belongs to the field of computers. The method comprises the steps that a touch locus input by a user on the touch screen is acquired; the touch locus is subjected to feature extraction; a locus feature of the touch locus is acquired; the locus feature of the touch locus is matched with a locus feature of a preset locus; and the touch screen is unlocked according to a matching result of the locus feature of the touch locus and the locus feature of the preset locus. The device comprises a screen input detection module, a feature extraction module, a feature matching module and a screen unlocking module. According to the method and the device, the touch locus input by the user on the touch screen is acquired, the locus feature of the acquired touch locus is subjected to the feature extraction, and the touch screen is unlocked according to the matching result of the locus feature of the touch locus and the locus feature of the preset locus, so that the possibility of accidental unlocking can be reduced, and privacy leakage of the user can be prevented.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a method and device for unlocking a touch screen of a terminal device. Background technique [0002] Mobile terminal devices have been widely used in people's daily life, for example, in mobile terminals such as PDAs (Personal Digital Assistants, personal digital assistants), palmtop computers, smart phones, and portable terminals. Touch is a commonly used human-computer interaction method, and users can input instructions and information by touching the screen. In order to protect the user's privacy and data, and prevent the user's misoperation, a locking method and device are often used for the touch screen of the above-mentioned terminal equipment. When the user uses the mobile terminal device, the process of unlocking the screen can be completed only by touching and unlocking the screen of the mobile terminal device. [0003] At present, the sliding unlocking method is comm...
