This paper explores the issue of data leakage detection. The unauthorized person transfers some important data to unknown person or outside the world from organization record. We developed data leakage detection software to overcome the important data leakage from organization. Data leakage detection is strategy for making sure that users do not send sensitive data or information to outside the world. In the organization, sometimes sensitive data must be handed over to trusted third parties from a user (guilty user). Distributor can easily accessible all information about guilty user for example: which file shares to fake agent from organization data records and there details etc. The main goal of the software is identify data leakages using some data allocation strategies and find out the fake agent and users who leak the important data. Data leakage prevention software also provides the essential security to data.
