Abstract EN
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 propose an improved ESRDH method using code division multiplexing and value expansion.
At the beginning, each pixel of the original image is divided into several parts containing a little signal and multiple equal signals.
Next, all signals are encrypted by Paillier encryption.
And then a large number of secret bits are embedded into the encrypted signals using code division multiplexing and value expansion.
Since the sum of elements in any spreading sequence is equal to 0, lossless quality of directly decrypted signals can be achieved using code division multiplexing on the encrypted equal signals.
Although the visual quality is reduced, high-capacity data hiding can be accomplished by conducting value expansion on the encrypted little signal.
The experimental results show that our method is better than other methods in terms of the embedding rate and average PSNR.
