Embodiment Construction
[0025] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the accompanying drawings.
[0026] A method for realizing power-on protection of a mobile terminal, as attached figure 1 As shown, the method includes:
[0027] Step 001, receiving and storing the preset power-on password input by the user;
[0028] Step 002, when the mobile terminal enters the boot interface, load and execute the boot protection program, prompting the user to input the boot password;
[0029] Step 003, verify the power-on password input by the user, when the input password is consistent with the preset power-on password, load and execute the boot program, that is, start the operating system, otherwise go to step 004;
[0030] Step 004: Detect whether the number of consecutive input of the power-on password has reached the preset limited number of times, if not, prompt the user to continue to enter the power-...

The invention relates to a method for implementing start-up protection on a mobile terminal, which comprises the following steps: receiving and storing a preset start-up password input by a user; when the mobile terminal enters a start-up interface, loading and executing a start-up protection program and verifying a start-up password input by the user; when the start-up password is inconsistent with the preset start-up password and continuous input times of the start-up password reach preset limited times, loading and executing an unlocking program and prompting the user to input an unlock code, and when continuous input times of the unlock code reach preset limited times, a system enters a permanent dormant state; updating an operating system and writing an awakening code of the permanent dormant state into the operating system. According to the invention, not only can the valid user still normally use the mobile terminal by inquiring and inputting the unlock code to carry out unlocking when forgetting the start-up password, but also the leakage of personal information of the user can be avoided and the loss of the user is minimized.
Description
technical field [0001] The invention relates to the field of information security, in particular to a method for realizing power-on protection of a mobile terminal. Background technique [0002] With the rapid development of communication technology, mobile phones have become widely used and indispensable electronic products in people's lives. And along with the continuous increase of mobile phone functions, it is no longer just a simple communication tool, but more and more involves fields such as people's leisure and entertainment, file transfer. The mobile phone often stores a large amount of contact information of the user, and may even store the user's private information, important business information, etc., so once the mobile phone is stolen, the user will lose far more than the value of a mobile phone. Data loss may cause users to suffer immeasurable losses. [0003] Therefore, a power-on protection program is generally set in current mobile phones. Generally, th...
