Problems solved by technology
[0005] 1) The writing of the privacy policy is not standardized, and for the mobile applications of the specified classification, it cannot meet all the content covered by the relevant standards, that is, the privacy policy is incomplete, and there are missing items and missing items;
[0006] 2) There is a discrepancy between the writing of the privacy policy and the actual behavior of the software, which may be caused by the fact that the privacy policy writer does not understand the actual behavior of the application, or may be caused by the asynchronous update of the application and the privacy policy;
[0007] 3) The writing of privacy policies is almost entirely done manually, and the different modes and styles of writing have brought difficulties in standardization and automated analysis;
[0008] 4) The existing mobile application security analysis mainly focuses on the analysis of the underlying data flow of the code, and does not combine user interaction components for collaborative analysis

The invention discloses a privacy protection policy-oriented APP privacy data consistency behavior analysis method. The method is divided into two steps to analyze the software privacy policy and the actual behavior of the software: first, using the privacy policy integrity analysis method to compare the privacy policy Whether there is a problem of missing items or missing items; then by analyzing the user interaction components of the mobile application, understand and classify the component types, combine the data flow analysis of the software to determine the use of sensitive privacy data, and finally compare the behavior results with the privacy policy, Generate the discriminant results of the consistency between the behavior of mobile application software and the privacy policy. Through the above methods, it is possible to detect the integrity of the privacy policy, determine whether there is a contradiction between the right to use and the right to use the software, and improve the security of users when using mobile applications.
Description
technical field [0001] The invention relates to the field of privacy policy analysis in mobile applications, in particular to a privacy policy integrity analysis and a method for judging behavior consistency of applications. Background technique [0002] In recent years, my country's mobile APP industry has continued to develop. According to relevant data, in 2019, the total number of apps installed per capita by mobile netizens in my country continued to grow to 60, and the number of users is expected to reach 500 million in 2021. With the continuous expansion of the mobile application market, application software is becoming more and more complex, user data is becoming more and more insecure, and there are more and more unauthorized and ultra vires behaviors in applications. [0003] In order to protect the security of user data, the country stipulates that mobile applications need to have special privacy policy regulations, describing the permissions related to user priv...
