Method for detecting privacy leakage on basis of context information

The invention discloses a method for detecting privacy leakage on Android platforms on the basis of context information. The method comprises the following steps of: 1, carrying out static taint analysis on software to obtain a taint propagation path; 2, carrying out static function analysis on the software to obtain a software function calling map; 3, constructing a mapping relationship between Android authorities and APIs, and collecting a system and UI event information at the same time; 4, integrating data collected in the steps 1, 2 and 3, and constructing privacy-related API function context information; 5, intercepting privacy-related API functions used in the software, and constructing dynamic execution context information; 6, carrying out privacy leakage detection on the collecteddynamic execution context information and the privacy-related API function context information constructed in static analysis; and 7, if a similarity in the privacy leakage detection in the step 6 isgreater than or equal to
