Proving possession rights on outsourced relational databases may be a crucial issue in today’s internet-based application environments and in several content distribution applications. In this paper, a mechanism is provided for proof of possession supported the secure embedding of a sturdy unobservable watermark in relative information. We formulate the watermarking of relational databases as an affected optimisation downside and discuss economical techniques to resolve the optimisation downside and to handle the constraints. Our watermarking technique is resilient to watermark synchronization errors as a result of it uses a partitioning approach that does not need marker tuples. Our approach overcomes a significant weakness in existing watermarking techniques. Watermark decoding is predicated on a threshold-based technique characterized by threshold based technique that minimizes the likelihood of decoding errors. In this paper a watermarking technique is implemented and shown by experimental results that the proposed technique is resilient to tuple deletion, alteration, and insertion attacks.
