Detection of guilty agents by maintaining the confidentiality of the data on the web

A website is essential to publish and access information on the Internet. Website contains different web application programs, which has confidential data that needs to be secured. In business scenarios, company outsources some of their confidential data to other agents, these agents are called as trusted third parties. The owner of the data sends the confidential data to the trusted third party agents and there may be the possibility that any of the trusted agent can leak the confidential data. It is necessary to identify the guilty agent, who leaks the data to the unauthorized party. The existing system uses data allocation strategies and watermarking technique to add fake objects. But, it has some drawbacks, that watermarked data can be altered or modified. The proposed technique uses AES algorithm to encrypt the requested data. So that, unauthorised party is not able to view and access the confidential data. Thus it maintains the confidentiality of the data. Another technique used is Media Access Control (MAC) address to enhance the chances of detecting guilty agents.
