The invention discloses a device and method for unlocking a pattern of a touch screen. The device comprises an interface display module, an information acquisition module, a track acquisition module, a state acquisition module and a password comparison module, wherein the interface display module is used for arranging a plurality of preset contact areas on the touch screen to form and display an unlocking interface when sensing an unlocking request; the information acquisition module is used for acquiring touch information when a user inputs a touch operation on the unlocking interface; the track acquisition module is used for acquiring a touch track of the touch operation on the unlocking interface according to the touch information; the state acquisition module is used for acquiring contact areas through which the touch track sequentially passes and touch states of the sequentially passed contact areas according to the relative position relationships between the touch track and the contact areas and employing an ordered contact area sequence including the corresponding touch state as an unlocking password; and the password comparison module is used for comparing the unlocking password with a pre-stored password and unlocking a pattern lock of the touch screen if the unlocking password is matched with the pre-stored password. By the method and the device disclosed by the invention, the safety of the unlocking pattern is strengthened; and the problem of information insecurity of touch screen equipment is solved.
Description
technical field [0001] The invention relates to the technical field of touch screen unlocking, in particular to a touch screen pattern unlocking device and method. Background technique [0002] A few days ago, on touch screen devices, especially smart phones and smart wearable devices, the pattern unlock function is a low-strength encryption method, which has the characteristics of convenient operation, easy memory and recognition. It has been widely used in operational scenarios such as testing. However, in the existing pattern unlocking scheme, the unlocking pattern is an easy-to-remember pattern that passes through fixed points in an orderly manner. When the user unlocks the pattern in a public place, it is easy to be peeped at the screen and leak the unlocking pattern, resulting in unsafe touch screen device information. technical problem. Contents of the invention [0003] The main purpose of the present invention is to provide a touch screen pattern unlocking devic...
