Design And Implementation Of User Online Behavior Audit System Based On Mobile Internet

To ensure the security of mobile Internet, it makes sense to detect the suspicious behaviors in mobile Internet, trace the source of the mobile users, and provide different services according to the users’ different features and preferences, by analysis of user behavior on the Internet. The construction of a mobile Internet user behavior audit system is of great significance. Facing with massive amount of mobile Internet data, it was hard to identify such characteristics of mobile Internet behaviors, as well as identifying user’s identity in audit works.This paper is on the subject mobile Internet user online behavior audit, which summed up the problems encountered with the works of behavior auditing in Mobile Internet, as well as we made the disign and implementation of the Mobile Internet user online behavior audit system, refered to the researches and works at home and abroad. The main contents of this paper are as follows:First of all, this paper did the research on the technology of audit works on of online users’ behaviors, and summed up the methods and characteristics of the audit work, in order to do the theoretical basis for the system design. Further more, this paper designed the audit system for mobile user online behaviors, and proposed the system goal and the overall design framework. On the basis each function module was properly designed. Prticularly, based on the application of related technologies, this paper specifically designed implemented three features, which are as follows:the implementation of protocol analysis audit on user behaviors through deep packet detection technology; achieving the identification of the user’s mobile phone number through the analysis of Radius protocol of authentication and billing; achieving the web page title association and key words extracting, based on the Apriori algorithm and TF-IDF model. At the end of this paper, the audit system introduced, including the main functions of the system. The network behavior audit function were tested, as well. In this paper, we designed and implemented a Mobile Internet auditing system which has a good ability both on identification and data processing.The main results of this paper are as follows:first, we implemented the user online behaviors audit system which can identify a variety of user online behaviors in realtime, including more than 70 kinds of instant messaging applications; second, we implemented user’s identity identification, the system can efficiently bind the user’s identity to user’s behaviors; third, the system achieved the analysis of the user’s online behavior, which is prepared for data mining.Through research and analysis, this paper design and implement a mobile Internet user online behavior auditing system, the results show that this system can satisfy the system target proposed in this paper and the audit requirements of identifying the mobile Internet user online behavior.
