Abstract

Embodiments of the invention disclose an unlocking method applied to a terminal and the terminal. The unlocking method is used for improving the security of terminal unlocking. The method provided by the embodiment of the invention comprises the steps of acquiring X current sampling points along a current track of an unlocking pattern input by a terminal user, and obtaining coordinates of the X current sampling points; expanding the X current sampling points into N expanded sampling points by adopting an interpolation method according to the coordinates of the X current sampling points, and obtaining coordinates of the N expanded sampling points; calculating and obtaining an actual deviation D of the current track of the unlocking pattern input by the user relative to a reference track of the unlocking pattern by adopting a distance calculation method according to the coordinates of the N expanded sampling points and the coordinates of the N reference sampling points; and unlocking the terminal when a ratio of the actual deviation D to a reference deviation DM is less than or equal to a deviation value R.

Description

technical field [0001] The present invention relates to the communication field, in particular to an unlocking method applied to a terminal and the terminal. Background technique [0002] With the development of science and technology, mobile phones, as a kind of communication equipment, have become more and more powerful. With the advantage of being able to consult information anytime and anywhere, mobile phones have gradually become an important means for people to obtain information. [0003] Nowadays, the use of mobile phones is becoming more and more popular. In order to prevent the mobile phone from being abused by people other than the owner, causing the privacy of the owner to leak, the mobile phone allows the owner to set the authentication method when the phone is unlocked. For example, to set the unlock password, you can Input through the virtual keyboard or through graphics; other methods such as fingerprint unlocking can also be set. [0004] However, when the ...
