Abstract

One or more embodiments of this specification provide a method and apparatus for detecting information leakage of a third-party library, including identifying a source point for acquiring information about an application in a third-party library called by an application; starting from the source point, tracking the processing of information Path, determine the sink point of the information; if the sink point is located in a non-application, determine that the information is leaked through a third-party library; output information leakage prompt information. According to the method in this specification, it is possible to detect whether there is information leakage in the third-party library, and realize the security detection of the third-party library.

Description

technical field [0001] One or more embodiments of this specification relate to the field of information security technologies, and in particular to a method and device for detecting third-party database information leakage. Background technique [0002] With the popularization of smart terminals, the number of applications that can be installed on smart terminals has not only increased dramatically, but also has rich and varied functions, which has greatly improved user experience. The function implementation of some applications depends on third-party libraries, and the application functions are enhanced by calling various tool libraries. However, there may be malicious code implanted in the third-party library, and important data can be obtained illegally when the third-party library is called, resulting in the leakage of key information. Therefore, the detection of the third-party library is a key technology to ensure information security. Contents of the invention [...
