Abstract :

This paper proposes a scheme for Enhanced Separable Reversible Data Hiding in Encrypted images Using Side Match. In the first step the original image is encrypted using an encryption key. Then additional data is embedded into the image by modifying a small portion of the encrypted image using a data hiding key. With an encrypted image containing additional data, if a receiver has the data hiding key, he can extract the additional data. If the receiver has the encryption key, he can decrypt the image, but cannot extract the additional data. If the receiver has both the data hiding key and encryption key, he can extract the additional data and recover the original content by exploiting the spatial correlation in natural images. The accuracy of data extraction is improved by using a better scheme for measuring the smoothness of the received image, and uses the Side Match scheme to further decrease the error rate of extracted bits.
