Isolation protection system and isolation protection method of private data in mobile phone

Abstract

The invention provides an isolation protection system and an isolation protection method of private data in a mobile phone, which belongs to the field of mobile communication and information security. The system comprises a privacy storage area, an ordinary storage area, a setting module, an analysis judging module and a processing module, wherein the privacy storage area is used for storing the private data to be isolated and protected; data in the privacy storage area is stored in an encryption manner; the ordinary storage area is used for storing non-isolated protection data; the setting module is used for setting an identity authentication way and selecting private data needing to be stored into the privacy storage area; the analysis judging module is used for monitoring a system event in real time, when a data writing request is received, the analysis judging module judges whether the data writing request is the private data to be isolated and protected or not and transmits the judgment result to the processing module; when a private data access request is received, the identity authentication is carried out on a user according to the set identity authentication way; the processing module is used for encrypting the data when the judgment result of the analysis judging module is the data writing request and is the private data to be isolated and protected and transmitting a writing request to the storage module.

Description

technical field [0001] The invention belongs to the field of mobile communication and information security, and specifically relates to a system and method for isolation and protection of private data in a mobile phone, which realizes multi-dimensional isolation and protection of personal privacy data in the mobile phone. Background technique [0002] In recent years, my country's mobile Internet industry has developed rapidly, and the scale of network users has continued to expand. According to data from the 2012 China Mobile Internet Industry Application Conference, Chinese mobile Internet users exceeded 370 million in the first quarter of 2012. At the same time, the mobile smart terminal market is also developing rapidly. According to a report from the Ministry of Industry and Information Technology, the sales volume of mobile smart terminals in the Chinese market has reached 42 million units in the second quarter of 2012, making it the largest mobile smart terminal marke...

Problems solved by technology

[0009] First, the existing privacy protection is all through setting a private contact, and then storing the SMS, MMS and call record information related to the private contact in the private space, so only part of the contacts that are set as private can be guaranteed. Data is not leaked

If the user wants to protect all short and multimedia messages and all call records in the text message folder, then all contacts in the address book can only be set as private contacts, which is cumbersome to operate, and even so, for those numbers that are not in the mobile phone communication The information generated during the communication process between the numbers in the directory cannot be protected, resulting in the omission of protection

[0010] Second, although the existing mobile phone security software can encrypt and hide files, it must specify specific existing files.

If the user wants to protect all the files in a certain folder, then these files must be generated, and then manually specify one by one for encryption protection, which is very troublesome, and when a file has been generated, the user is likely to You will forget to specify encryption protection, which will also cause data leakage

[0011] Third, in the existing mobile phone privacy protection methods, for the protection of mobile phone applications, the application programs are generally locked, but the user data generated during the use of these mobile phone applications is not protected. The levels are uneven, which can easily cause user data generated by applications that do not consider security well to be easily obtained by criminals, resulting in the leakage of user privacy data

[0012] It can be seen from the above aspects that the existing mobile phone privacy data protection scheme is not complete, not strict, and inconvenient to use
