Abstract: In reversible compressed image data hiding, the exact cover image is restored at approximate efficient rate after extracting the secret data from the stego-image. The improved version of the traditional histogram shifting method as proposed, prevents overflow and underflow to a greater extent. The primary objective of this paper is to develop a high data hiding capability in histogram-based reversible data hiding algorithm by introducing a relatively lower distortion after embedding the secret message.
