Privacy protection method and system for common database of Android mobile phone

Abstract

The invention, which belongs to the mobile communication and information safety field, provides a privacy protection method and system for a common database of an Android mobile phone. The method is characterized in that a user sets privacy data that are going to be stored into a privacy database, all privacy data are transferred to a designated privacy database from a common database after successful setting and are stored in an encrypted mode, and a designated common database are monitored dynamically, wherein the privacy database is used for storing privacy data that are designated by the user and need encryption protection. Any user of a mobile phone terminal has access to data in the common database; and only a user with successful identity authentication can access data in the privacy database. The privacy data include a short message, a call record, and contact information. The designated privacy database includes a privacy short message database, a privacy call record database, and a privacy contact database. And the designated common database includes a short message common database, a call record common database, and a contact common database.

Description

technical field [0001] The invention belongs to the field of mobile communication and information security, and specifically relates to a method and system for protecting the privacy of an Android mobile phone public database, which can protect user privacy data such as short messages, call records, and contact information on an Android mobile phone terminal that has not been rooted, and prevent Privacy data leakage. Background technique [0002] In recent years, with the rapid development of the mobile Internet, the market for mobile smart terminals is also developing rapidly. According to the research report of the Ministry of Industry and Information Technology, the sales volume of domestic mobile smart terminals in the second quarter of last year has exceeded 40 million units, and China has become the world's largest mobile smart terminal market. [0003] With the continuous development of technology and the rapid popularization of mobile phone applications, mobile phon...

Problems solved by technology

Then when the dynamic monitoring function of privacy behavior fails to work, the data in the public database will be exposed to other applications, especially malicious software will easily obtain the user's private data, resulting in the leakage of user's private data

[0007] It can be seen from the above aspects that the existing mobile phone privacy data protection schemes, especially for contact information, SMS records, call records, etc., are stored in public databases and are the most private data protection for users. imprecise

For Android phones that have not obtained root permissions, the scope of security enhancement of these existing mobile phone privacy protection schemes is limited to a certain extent.
