Reversible Data-Hiding Scheme Using Color Coding for Ownership Authentication

The concept of reversible data hiding (RDH) enables the full restoration of the cover image while simultaneously recovering the concealed data from a previously obscured image. Hence, it is the favored choice when complete restoration of the cover image is required in situations where the concealment of critical data is important. This work introduces a system that utilizes interpolation-based color coding method (CCM) to temporarily conceal data without permanent deletion. The refinement of the expanded form of the original image is achieved by the utilization of two distinct methods, namely enhanced neighbor mean interpolation (ENMI) and modified neighbor mean interpolation (MNMI). This procedure is conducted prior to the inclusion of any confidential data. The experimental findings indicate that the suggested approach has the potential to be implemented and exhibits superior performance compared to standard methods in relations of highest signal-to-noise ratio and data whacking size.
