[0003] Although the password or PIN code of the mobile terminal can prevent the mobile terminal from being used illegally, anyone can see the interface where the password needs to be entered, so as to know that the mobile phone has been locked. At present, there is no hidden password to protect the mobile terminal. not used

Embodiment Construction

[0021] The main technical idea of ​​the present invention is: set the built-in lock activation password and unlocking password for the mobile terminal in advance, input the built-in lock activation password in any state after the mobile terminal is turned on, the mobile terminal enters the built-in lock lock state, and the mobile terminal stops the key operation at this time In response, in the built-in lock state, when the mobile terminal receives the correct unlocking password input by the user, it can return to the normal working state. The invention is a supplement and improvement to the protection mechanism of the internal storage information of the mobile terminal in the prior art, and meets the requirement of the user to protect the mobile terminal by using a concealed password.

[0022] The specific implementation process of the present invention will be described in further detail below in conjunction with each accompanying drawing.

[0023] see figure 1 , this figur...

Abstract

The invention discloses a protection method of the internal storage information of a mobile terminal and the mobile terminal. The protection method comprises the following steps: the mobile terminal receives and stores a dormant lock starting code set by a user and decodes the dormant lock code; after the mobile terminal receives the correct dormant lock starting code input by the user, the mobile terminal enters a dormant lock locking state and stops responding to keyboard operation under the dormant lock locking state, and after the mobile terminal receives the correct decoding dormant lock code input by the user under the dormant lock locking state, the mobile terminal recovers to a normal working state. The mobile terminal comprises a code storage module, a locking state trigger module and a judging module. After the protection method is adopted, the mobile terminal externally provides no responding information in the state converting process from a normal state to a locking state to an unlocking state to the normal state so that external world can not obtain the encryption operation of the user, the secret keeping property of the mobile terminal is enhanced, and data of the user can be effectively protected.

Description

technical field [0001] The invention relates to mobile terminal technology, in particular to a method for protecting information stored inside a mobile terminal and the mobile terminal. Background technique [0002] In order to prevent the leakage of information stored in the mobile terminal or the illegal use of the mobile terminal, the password or PIN code provided by the mobile terminal is usually used to provide protection. Generally, the password or PIN of the mobile terminal can be opened and set through the setting function password, so that when the mobile terminal is restarted next time, it will enter the password or PIN code input interface of the mobile terminal. If the password or PIN code is entered incorrectly, it cannot be turned on or the corresponding function cannot be used. All mobile terminals currently on the market already have this function. [0003] Although the password or PIN code of the mobile terminal can prevent the mobile terminal from being us...
