Embodiment 1

[0024] A method for multi-level locking and multi-level unlocking for mobile devices, the specific steps comprising:

[0025] (1) Multi-level locking: In the system settings of the mobile device, a module for user-preset locking methods is reserved. Users can preset the system's locking level, system-level password, startup password of each application and The list of applications that need to use the startup password under each locking level is stored in the system file. Different locking levels correspond to different system-level passwords and the list of applications that need to use the startup password; where the system-level password includes the startup password and Screen lock password, power-on password refers to the password that the user needs to enter when turning on or restarting the mobile device; lock screen password refers to the password that the user needs to enter when unlocking the screen of the mobile device; the system of the mobile device automatically s...

Embodiment 2

[0034] According to a method for multi-level locking and multi-level unlocking of mobile devices described in Embodiment 1, the difference is that in step (1), the locking levels of the system include primary locking, secondary locking, Three-level lock and four-level lock. When the first level is locked, when the user enters the power-on password or lock screen password to enter the system, all applications on the mobile device do not need to use the startup password, so that all applications can be accessed and viewed at any time. All materials; when the second level is locked, when the user enters the power-on password or lock screen password, some applications on the mobile device need to use the startup password and some applications do not need to use the startup password, which can protect the data of more private applications; the third level of encryption When locked, when the user enters the power-on password or lock screen password, all applications on the mobile dev...

Abstract

The invention relates to a multilevel locking and multilevel unlocking method for a mobile device. The method comprises the following specific steps: (1) multistage locking: a user presetting a locking level of a system, a system-level password, a starting password of each application and an application list requiring to use the starting password under each locking level, wherein the different locking levels are corresponding to different system-level passwords and the application list requiring using the starting password; (2) multilevel deciphering: 1) when the user inputs the password to power on the mobile device or unlock the screen, the system acquiring the password input by the user; 2) judging whether the input password is any one of the power-on password or the screen-locking password, if so, judging the locking level, and notifying all applications on the mobile device, judging whether the starting password requires to use. Through the adoption of the method provided by the invention, the data security of the mobile terminal under special scene can be protected, the specific scene is mainly the scenes that the mobile device is lent to friends and strangers or the mobile device is lost.

Description

technical field [0001] The invention relates to a multi-level locking and multi-level unlocking method for mobile equipment, belonging to the technical field of mobile terminals. Background technique [0002] In recent years, portable mobile terminals are developing toward high configuration and intelligence, and traditional keypad input devices have almost been replaced by touch screens supporting multi-touch. Mobile terminals represented by smart phones are playing an increasingly important role in people's daily life. In addition to traditional communication functions, they also have various advanced functions such as instant messaging, photography, data storage, and payment. At the same time, smart phones are facing more and more security problems, especially when the mobile phone is used by a stranger or lost, the private data in the mobile phone will be easily stolen by others. [0003] At present, the security mechanisms of mobile terminals mainly include power-on pa...
