An Implementation of Secure Data Exchange Ensuring Authentication and Authorization Using Color Drops

摘要

Secure communication is when two entities are communicating and do not want a third party to listen in. For that they need to communicate in a way not susceptible to eavesdropping or Interception. Here maintain user privacy, and preserve data integrity via Encryption and decryption technique. Using a trustoverlay network over multiple data centers to implement a reputation system for establishing trust between Sender and receiver is becoming mandatory. Cryptographic techniques protect shared data objects and ensure the security level data transfer process. These techniques safeguard multiway authentications and strengthen the security for accessing confidential data in both public and private. However the problem there is no guarantee that only the legitimate user is accessing the confidential data and maintaining privacy till the user quits the secured communication. Hence to overcome the problem the Data coloring and software watermarking techniques is established to provide the authenticity that is legitimate user only sent the data.
