New Approaches to Data Classification in DLP Systems

In this paper, we present possible ways of DLP system development in the future; we also make an introduction to current algorithms and methods widely used in DLP systems and demonstrate our techniques that are supposed to be a solution to some data leakage problems. We describe traffic classification and methods of its analysis depending on data types. We analyze application of specific algorithms and their effectiveness in the aspect of personal data protection. We evaluate our algorithms on our own corpus that we assembled from typical confidential documents; we also demonstrate the difference between the results of standard data processing approach and new data analysis algorithms.
