Abstract

The invention discloses a mobile phone data security protection method, and belongs to the technical fields of information security and mobile communication. The method comprises the following steps: a) creating a virtual disk file on a mobile phone, wherein the virtual disk file comprises a file head part and a file content part, the file head part comprises an encryption algorithm one and a key one, the file content part is used for storing data, the data is encrypted and stored through the encryption algorithm one and the key one, and the file head part is encrypted and stored through an encryption algorithm two and a key two; b) loading the virtual disk file on the mobile phone, and decrypting the file head part through the encryption algorithm two and the key two in the loading process; and c) after the virtual disk file is loaded, when reading the data stored by the file content part, decrypting the read data and outputting the data, and when writing data into the file content part, encrypting the data written in and storing the data in the file content part, wherein the encryption and decryption are performed through the encryption algorithm one and the key one. The method can be used for mobile phone data security protection.

Description

technical field [0001] The invention relates to a mobile phone, in particular to a mobile phone data security protection method, which belongs to the technical fields of information security and mobile communication. Background technique [0002] The security protection of data on mobile phones has attracted more and more attention. In the known prior art, there are many methods for protecting mobile phone information, but generally selected files or folders are encrypted. For example, the patented invention "Secret Processing Method of Mobile Information" (200710172338) is to select files or folder nodes on the file directory tree of the mobile phone to set encryption or de-encryption, so as to achieve the confidential processing of mobile phone information. [0003] With the promotion of 3G technology and the popularity of smart phones, the functions of mobile phones are becoming more and more powerful. Mobile phones are not only used for personal consumption, but also fo...
