Problems solved by technology

[0005] Since the deleted data in the data partition of the mobile terminal may be restored, when the mobile terminal has saved data, it may be restored even if the data is deleted, which reduces the security of the mobile terminal, resulting in particularly sensitive data leakage or even a to cause significant economic losses, unable to meet the market's demand for mobile terminal security

Abstract

The present invention discloses a method and apparatus for safe deletion of data in a mobile terminal. The method comprises that when a deletion message is received, and if safe deletion of data is required, random data are generated and cover to-be-deleted space indicated by the received deletion message so as to achieve the safe deletion. According to the technical scheme, the already deleted data in the mobile terminal are prevented from being recovered, safety of the mobile terminal is improved, and requirements of the market on mobile terminal safety are satisfied.

Description

technical field [0001] The invention relates to mobile terminal technology, in particular to a method and device for realizing safe deletion of data in a mobile terminal. Background technique [0002] As we all know, with the widespread use of mobile terminals, users of mobile terminals store a large amount of important or private data (hereinafter collectively referred to as sensitive data) in the mobile terminal, such as important documents, private photos, and private videos. Usually, the operating system of the mobile terminal stores sensitive data in a built-in non-volatile memory or a data partition of an external memory card. Wherein, the data partition such as the secure digital memory card (SDCARD, SecureDigitalMemoryCard) partition of the Android (Android) operating system is used for based on a file system such as a new technology file system (usually called NTFS file system, NewTechnologyFileSystem) or a 32-bit file allocation table file The system (FAT32 file s...
