Reversible Data Hiding on Encrypted Digital Images

Kranti U. Patil, J. V. Shinde

Abstract: Recently, Reversible data hiding is a point of attention. Reversible data hiding in encrypted images is mostly used since it maintains excellent property that the original cover image can be recovered losslessly after the embedded data is extracted. By using this technique the confidentiality of image contents is also maintained. This paper proposes a novel reversible data hiding technique for digital color image. This technique guarantees effective retrieval of hidden data in color image without degradation in the quality of color image. The cryptographic methods are used to encrypt & decrypt the data to increase the security. The proposed method is enhanced from text data to any data type like text, video, audio etc. In this system only digital image is considered as cover for data hiding purpose.
