Nowadays data leakage is the big problem in front of the different kind of institution, organization, and security firms. Everyone knows what is important of sensitive data .The unveiling of sensitive data in storage and transmission creates a serious threat to organizational and personal security. The system propose a privacy-preserving data-leak detection model for preventing accidental data leak in network traffic as well as focus on designing a host-assisted mechanism for the complete datarevelation for organizations. Here Human misstep is the primary reason for data leak. The advantage of this system is without disclosing the sensitive data, information owner safely assign the detection operation to a DLD provider. In this paper the system used data leak detection (DLD) on the basis of summaries of information and depict how Internet service providers can offer their clients DLD as an extra service. It can be outsourced and be deployed in a semi-honest detection environment. The evaluation results show that this approach can support accurate detection with very less number of false alarms under various data-leak scenarios.
