What are the ways for mobile apps to leak personal information?

Crossing the boundary to obtain privacy permissions

Mobile phone contact permissions. Data shows that in 2018, China's various mobile phone apps have become the hardest hit area for privacy violations. Six categories of apps, including social networking, video, and online shopping, accounted for more than 50% of access permissions, with the highest reaching 86.7%. The reason is closely related to the marketing strategy of mobile app manufacturers to promote social communication on the platform and build a community of acquaintances.

Read SMS permissions. App SMS read permission is often used to automatically extract user SMS verification codes, which helps users improve the efficiency of App SMS verification operations. However, when it comes to reading the rest of the user's personal text messages, the App's reading permissions are not effectively supervised or restricted. Some illegal apps may be able to use this permission to steal the user's SMS information. Data shows that the four categories of mobile information reading, social networking, financial management, and travel apps have call permissions accounting for no less than 30.0%, seriously threatening the security of users’ privacy information.

Get positioning information. According to the functions of mobile phone apps, map, travel, online shopping, and social networking apps have positioning functions. Obtaining user location information is conducive to providing more accurate services, which is a reasonable demand. However, investigations show that some mobile video, audio, information reading, and tool mobile apps still retrieve and abuse location information.
