Abstract

The invention proposes a dynamic decryption method used for a mobile terminal. The method includes the following steps: detecting whether a password input interface is entered; if so, further judging whether at least one character input button is triggered; if so, further detecting a fixed-character region corresponding to the triggered character input button; obtaining dynamic characters corresponding to fixed characters according to the fixed-character region until an input completion instruction is received so as to obtain an input dynamic-character sequence; judging whether the dynamic-character sequence matches a preset password; and if the dynamic-character sequence matches the preset password, unlocking the mobile terminal. The dynamic decryption method used for the mobile terminal is capable of preventing effectively that the password is peeped by others so that password leakage is prevented and thus the security of the mobile terminal is improved. The invention also proposes the mobile terminal.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a dynamic decryption method for a mobile terminal and the mobile terminal. Background technique [0002] The mobile phone password is used to prevent the operator from turning on the mobile phone or operating certain applications of the mobile phone when the mobile phone is not used by the owner. There are generally two settings for current mobile phone passwords: 1. Use numbers or text as passwords, such as figure 2 As shown, this method requires the user to input a string of letters or numbers each time before operating the mobile phone, so as to achieve the encryption function. 2. Use a specific connection pattern as a password. In this method, the user sets a certain pattern in advance, and the user is required to draw the same pattern to unlock when unlocking. [0003] At present, the above two encryption schemes can easily lead to leaks in public places. For exa...
