Research And Implementation Of Mobile Terminal Information Protection Technology Based On Intention

As mobile terminals occupy a higher and higher position in people's lives,the protection of user sensitive information on mobile terminals is becoming more and more important.In the process of user use,especially in high security scenarios,how to get a good protection effect and user experience,and get a good balance between them,is still a problem.In order to obtain good protection effect and user experience,sensitive information protection needs to focus on user intention.There are disadvantages in user intention analysis effect and user experience,and it is difficult to maintain a good balance between protection effect and user experience in the existing research of Android terminal sensitive information analysis and protection,especially in high security scenarios.This paper introduces the concept of trigger point to solve the problem.A sensitive information usage analysis method based on user intention and a sensitive information real-time protection method considering user intention are researched and implemented.The main work of this paper is as follows:1.The existing sensitive information analysis methods in real-time protection have their disadvantages and is difficult to get a good balance between the protection effect and user experience.This paper proposes an analysis entry point,the sensitive information user intention trigger point.The concept of the trigger point contribute to the balance between protection effect and user experience.Design an automatic extraction method of trigger point and an intention analysis algorithm based on deep learning which considers both image and text features in order to get the user intention.Compared with the existing similar methods,the training efficiency of intention analysis algorithm is improved by 6-10 times,and the precision rate,recall rate and accuracy rate are improved by 1.5%-4%.2.Aiming at the problem that the user intention analysis effect and the user experience have defect as well as the problem that protection effect against user experience in existing protection research,this research designs a real-time sensitive information protection method based on user intention analysis.This research ensure the analysis and protect effort through environment analysis,trigger point,third-party library analysis and multi-level protection.Through the technical means and the characteristics of trigger point analysis,the user experience is considered.
