A Database Watermarking Algorithm Using Secret Sharing Technology
Considering the security issues in database joint owners authority management and in modification of databasewe put forward a database watermarking algorithm based on secret sharing technology.In the algorithmthe relational databases used secret sharing technology to embed the watermark in the databaseand n times of interpolation were implemented to the database watermarking using Lagrange interpolation formulathus to realize database watermark embedding and recoveryand the database owner could be jointly responsible for the security of the database and robustness.Simulation experiments showed that the proposed algorithm can reduce the redundancy of database enhance security safety of database watermarkand has certain robustness to watermark detection when some of the data in the database are deleted.
