Block-Based Image Reversible Data Hiding Based on the Visual Feature and Edge Entropy

Due to the widespread usage of the Internet, electronic information can be quickly altered, duplicated, and shared across interconnection. As a result, the unauthorized reproduction of digital material became a severe issue. Reversible data hiding (RDH) was a practical way of protecting digital media's copyright. This research presents an enhanced DCT-based RDH method that considers human visual features. A less uniform block was used for the information embedding to achieve high imperceptibility for a block based RDH technique. The testing findings of the suggested technique shown a better increase in robustness and non - repudiation under various kinds of image alteration procedures.
