java code for [b] relational database watermarking [/b]

Abstract:

Proof of ownership based on the safe embedding of a strong irreversible watermark in relational data. We prepare watermarking of relational databases as a limited optimization problem and discuss efficient techniques for solving optimization problems and handling obstacles. Watermark decoding is based on a threshold-based technology that is described by optimum threshold which reduces the possibility of decoding errors. We implemented our watermarking technique to implement the concept of concept and experimental results showed that our technique is flexible for deletion, transformation, and inclusion attacks. Watermark describes such information that can be used to prove the ownership of the data, such as the owner, origin, or recipient of the content. We develop an efficient technique for identifying watermarks, which is based on an optimum range. The optimum threshold has been reduced by reducing the probability of decoding error.
