Problems solved by technology
[0004] Although there are many permission management applications and mobile phone management applications on the market, the effect is not satisfactory.
Mobile phone management applications need to periodically kill resident processes by enabling multiple management services in the background. This method consumes a lot of performance such as memory and battery
Some applications refuse to provide privacy API interfaces to unauthorized programs by modifying the bottom layer of the system, but this method requires Root permissions, and may cause the program to fail to obtain permissions and crash, and the user experience is not good
Moreover, it is becoming more and more difficult to obtain Root permissions in many systems, because obtaining Root permissions is likely to bring more serious security risks, so mobile phone manufacturers have restricted them.

The invention provides a privacy information protection method and device based on a virtual application and a storage medium. The method includes: obtaining an application package and application information used for virtual application; constructing a sandbox for running the virtual application and creating a proxy service in the sandbox; installing the virtual application in the sandbox; creating a child process of the virtual application in the sandbox and replacing the child process with a proxy service process; intercepting the system API for obtaining user information by the virtual application and monitoring the behavior of the virtual application, and returning the system API called by the virtual application as the information set by the user or random information. The method ofthe invention enables the information obtained by calling the system API to be intercepted, has high protection degree and good stability, and the sandbox of the invention is not the virtualization ofthe instruction level, only the service of Android and the part of the Hook API are proxied, having little influence on the system performance, and needing no root permission.
Description
technical field [0001] The invention relates to the technical field of data security, in particular to a virtual application-based privacy information protection method, device and storage medium. Background technique [0002] With the continuous development of mobile communication technology, the market share of the Android system continues to increase. According to a report released by the market research agency Gartner in 2018, the data shows that the Android system accounted for 85.7% of the smartphones sold globally last year. . With the development of mobile technology, technologies such as mobile payment, online shopping mall, instant messaging, etc. have greatly facilitated our daily life. [0003] At the same time, in terms of mobile phone security, problems such as mobile phone viruses, malware, ad flooding, abuse of authority, privacy leaks, etc., seriously threaten Android users. At present, most applications on the market obtain a large number of application p...
