Data security method of memory card

Abstract

The invention relates to a data security method of a memory card. The data security method includes that a mobile terminal acquires identity of the inserted memory card so as to judge whether the memory card is used for the first time or not, if yes, the mobile terminal can be bound with the memory card, if not, all data in the memory card can be eliminated; the mobile terminal can cut the data to be secured in the internal storage space into the memory card. When the mobile terminal monitors power failure of the memory card, the data in the memory card can be eliminated. By the data security method, data on the mobile terminal can be effectively isolated, and data security and safety are ensured.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a data security method of a storage card. Background technique [0002] At present, the use of mobile terminals by governments and enterprises to handle affairs increases, and the issue of data security and confidentiality on mobile terminals has been paid more and more attention. However, both office applications and private applications are running on the same mobile terminal. Once the mobile application reads and modifies government and enterprise data without authorization, it may cause government or enterprise secrets to leak and pose a security threat. There is an urgent need to effectively control the reading and processing of government and enterprise data stored and processed on mobile terminals to ensure its security and confidentiality. [0003] There are currently two confidentiality schemes. [0004] 1. In my country's existing MDM products, mobile terminal data p...
