Improved Encrypted-Signals-Based Reversible Data Hiding Using Code Division Multiplexing and Value Expansion
Compared to the encrypted-image-based reversible data hiding (EIRDH) method, the encrypted-signals-based reversible data hiding (ESRDH) technique is a novel way to achieve a greater embedding rate and better quality of the decrypted signals. Motivated by ESRDH using signal energy transfer, we propos...
