Secured Privacy Preservation for Sensitive Data Exposure by using Digital Envelope

Leakage of data has drastically take place in the recent year. Data leakage problem face by many security companies, analysis institutions and government companies say the survey. From the distinguishable of data leak cases, human mistake are responsible for the data leak from the data leak. Many researcher work on this issues for detecting inadvertent sensitive data leak occurred by the mistakes of human. In the existing system they solve the data leakage problem, existing method implement the method for detecting the data leak. But existing method does not provide the security to the data or the system. The existing method is not secured. Overcome this issue, introduced the method which provides security to the data leak detection system. Also we introduced the concept of digital envelope, in which encrypt the data and send to the DLD system. System used ECC algorithm for security purpose. Here also introduced the bloom filter system for storing the hash values of the data. Finally measure the experimental result plot the graph and compare the result with existing and proposed system.
