Privacy Protocol Analysis based on Android Application

With the number of mobile applications increasing year by year, users may consciously or unconsciously provide personal information to the application, some of which have illegal access to and disclosure of user's information behavior, user privacy security is greatly threatened. And because the privacy protocol is too lengthy, users don't care about the content of the privacy protocol, so they ignore the problematic behavior. To solve this problem, we analyze and study the privacy protocol based on the Android application, and propose a method to detect the sentences related to personal information operation in privacy protocol documents. To help users quickly read the personal information-related content in the privacy protocol document, we create Verb List, Negative Word List, and Noun List related to the user's information operation, and combine them to detect the sentences related to the user's personal information.
