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. © 2022 IEEE.
