Method and device for destroying terminal data

Abstract

The invention discloses a method for destroying terminal data, which comprises that: a remote terminal sends a destruction command to a terminal; and the data destruction module of the terminal resolves the destruction command and destroys data according to the priority carried by the destruction command and the result of the resolution. The invention also discloses a device for destroying the terminal data. When the method and the device of the invention are adopted, the illegal acquisition of secret data is avoided, and the restoration of deleted data is prevented.

Description

technical field [0001] The invention relates to the field of electronic communication, in particular to a method and device for destroying terminal data. Background technique [0002] With the development of society and the improvement of people's living standards, mobile terminals, such as mobile phones, are becoming more and more popular and become an indispensable communication tool in people's daily life. At the same time, with the development of communication technology, some functions implemented on the computer will be implemented on the mobile phone, for example: the space of the internal or external storage device is getting larger and larger, etc. The development of this technology, on the one hand, facilitates users. Users can store files in the storage device of the mobile phone, which will also bring the risk of data leakage to mobile phone users. Even if the user has deleted the data on the mobile phone, because the deletion is not complete, it may be restored ...

Problems solved by technology

At the same time, with the development of communication technology, some functions implemented on the computer will be implemented on the mobile phone, for example: the space of the internal or external storage device is getting larger and larger, etc. The development of this technology, on the one hand, facilitates users. Users can store files in the storage device of the mobile phone, which will also bring the risk of data leakage to mobile phone users. Even if the user has deleted the data on the mobile phone, because the deletion is not complete, it may be restored by illegal users. illegal use

[0003] In the patent CN101600208, a system and method for automatically destroying data stored in mobile phones are provided, but this solution only deletes data, and there is a risk of illegal recovery of deleted data

In the patent CN200610060652.X, a kind of use of activation code matching is provided, and then the data in the destruction area in the terminal is destroyed according to the matching situation, and the relevant data is covered, but this patent only considers the destruction of the internal storage data of the mobile terminal, and does not Consider the destruction of data in external storage devices and Subscriber Identity Module (SIM, Subscriber Identity Module) cards. At the same time, the destruction of data in the destruction area takes a certain amount of time. When the data is not completely destroyed, it is forcibly cracked to obtain the data. possible
