Embodiment 1

[0092] image 3 It is a flow chart of a method for protecting terminal data applied to a sub-terminal according to an embodiment of the present invention. The following is combined with image 3 To describe a method for protecting terminal data applied to a sub-terminal according to an embodiment of the present invention, the method is applied to a sub-terminal, and a parent terminal is bound to the sub-terminal, and the sub-terminal establishes a corresponding relationship between data types and characters table, the data type is the type of data stored in the sub-terminal, such as image 3 As shown, the method includes the following steps:

[0093] S100. Collect current usage parameters of the sub-terminal;

[0094] S200, judging whether the acquired usage parameter satisfies a preset trigger condition, and if so, sending the corresponding relationship between the data type and the character and the preset character corresponding to the deletion of all data of the terminal...

Embodiment 2

[0110] Figure 4 It is a flowchart of a method for protecting terminal data applied to a sub-terminal according to another embodiment of the present invention, such as Figure 4 As shown, on the basis of including the above steps S100, S200, S300 and S400, this embodiment further includes:

[0111] S010, when receiving an instruction to bind the parent terminal, cut out an edit box;

[0112] S020. Receive the input terminal number of the parent terminal;

[0113] S030. When receiving the save instruction, bind the received terminal number with the terminal.

[0114]The terminal number of the parent terminal may be an IMSI (International Mobile Subscriber Identification Number) code of a SIM card used by the parent terminal, or an IMEI (International Mobile Equipment Identity) code of the parent terminal itself.

[0115] In the specific implementation of this embodiment, for example, under the setting lock function, an option of "Bind the home phone number" may be added. Whe...

Embodiment 3

[0118] Figure 5 It is a flowchart of a method for protecting terminal data applied to a sub-terminal according to another embodiment of the present invention, as shown in Figure 5 As shown, on the basis of including the above steps S300 and S400 in this embodiment, the above step S100 is specifically:

[0119] S110. When it is detected that the screen of the sub-terminal fails to be unlocked, count the number of consecutive unlocking failures;

[0120] The above step S200 is specifically:

[0121] S210. Determine whether the counted number of times exceeds a preset threshold, and if so, determine that the acquired usage parameters satisfy a preset trigger condition, and send to the parent terminal the corresponding relationship between data types and characters, as well as preset and delete all data of the terminal the corresponding character.

[0122] The above-mentioned preset threshold may be two times, three times or four times.

[0123] Considering that after someon...

Abstract

The invention discloses a mobile terminal, and a terminal data protection method and a device, which belong to the technical field of mobile terminals. The terminal data protection method is applied to a sub terminal, a master terminal is bound with the sub terminal, the sub terminal builds a corresponding relation table between data types and characters, and the data types are types of data stored by the sub terminal. The method comprises steps: current use parameters of the sub terminal are acquired; whether the acquired use parameters meet a preset triggering condition is judged, if yes, the corresponding relation between the data type and the characters and preset characters corresponding to all deletion terminal data are sent to the master terminal; characters returned by the master terminal are received; and according to the received characters, data of the type corresponding to the received characters are sent to the master terminal / all data stored in the sub terminal are deleted. The memory consumption of the mobile phone can be effectively reduced, the lasting capability of the mobile phone is added, and important data in the mobile phone are protected.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a mobile terminal and a method and device for protecting terminal data thereof. Background technique [0002] Mobile phones are currently an inaccessible communication tool in our lives. Losing mobile phones is sometimes difficult to find, which usually brings great inconvenience to our lives, because some people like to save important data information in mobile phones, such as using Documents, material photos, etc., or binding bank cards and other information through software, if they are picked up by illegal people, it may bring great trouble to our lives. [0003] At present, most of the existing methods to protect user data are to remotely delete the data in the mobile phone by enabling anti-theft software and then logging in to the corresponding associated website, or by sending deletion instructions to the lost mobile phone. This method requires the user to...
