A Real-time Data Leakage Detection Method On The Local Side

The popularity and development of the mobile Internet has brought great convenience to all aspects of people's lives,but at the same time,in order to use these convenient functions,people need to transmit a large amount of private data containing personal information through the Internet.Data leakage caused by various reasons has also attracted more and more attention.This paper investigates and studies the existing data leakage detection technology.Through comparative analysis of related work,we can find that the current data leakage detection methods have certain deficiencies.On the one hand,most methods cannot guarantee the security of the data in the detection.On the other hand,some methods using the cloud computing resource may result in false positives and cannot guarantee the real-time detection.In order to solve the above problems,this paper proposes a real-time data leakage detection method at the local side,which studies the real-time detection and the security of the data in the detection.The main work of this paper is as follows:This paper presents a local real-time data leakage detection method.The method can be divided into three stages.In the preprocessing stage,the text data to be detected is received,and the text data is segmented into an appropriate length.During the data transformation phase,the text data and the locally stored private database for detection are transformed by XOR operation,and then the privacy database is reordered to restore all the private data.The operation at this stage can effectively protect The security of the data in the detection.In the detection phase,data leak detection is performed using an improved suffix array algorithm for text data.This article also optimizes all data processing flows in the entire approach to further improve performance.The paper uses Java to implement the proposed method,and tests its performance through comparative experiments and simulation experiments.The results show that the proposed method can guarantee the real-time detection under the premise of data protection,and has higher detection e ciency than the existing data leakage detection method.
