Framework for Cloud Database Protection by Using Reversible Data Hiding Methods
Guan-Yu Wu, Che-Wei Lee · 2019
A new framework of data security for database numeric data by using reversible data hiding method is proposed. In the framework, reversible data hiding (RDH) methods are recommended to encode the to-be-protected numeric data in databases for hiding copyright information. Via the use of the proposed framework, not only the values of leaked numeric data are unreal but the copyright information can be extracted from the leaked numeric data to assert the ownership and disclose the illegal behavior. Furthermore, the real values of the leaked numeric data can be regained by performing the reverse process of the RDH method.
