摘要：Ownership rights on outsourced relational database are very crucial issue in today抯 internet environment and in many content distribution applications, because the rapid growth of the internet and related technologies offered an unprecedented ability to access and redistribute digital content. In earlier existing systems the relational data will be watermarked and directly send to the client system, in these systems while sending relational data from server to client attacker easily copy the data and create same copy of relational data. Here there is no security to watermarked relational data. In our proposed system before sending the watermarked relational data to client side we encrypt the relational data and send it to the client side, at client side decryption will be done to get the original watermarked data. Because of using this encryption technique even an attacker copy the data he/she may not read the watermarked relational data.
