Were also studied methods of pattern search, pattern recognition characters, as well as methods of dealing with noise.The research program has been developed that allows users to recover chat history using screenshots of your desktop, the program have a learning function of the system. The developed software can use multiple computers to increase the speed of analysis. The method of search boundaries of the active window is a generic search method to improve the quality of character recognition method was used median filtering . The character recognition is performed using a pattern recognition method of characters.The program can be used to locate the source of leakage of corporate data .In the future planed to develop an algorithm that allows to use the program for the analysis of more programs , this improvement will greatly expand the scope and increase the performance of the individual modules.
