Abstract : This paper proposes reversible and reliable data hiding in images. Nowadays system encryption and security has become a challenging thread for the society. Thus, we have made a move towards understanding and developing an enhanced version of reversible encryption technique under critical scenario of design. The system aims to achieve a high threshold value analysis under a reduced SNR (Signal to Noise Ratio) and PSNR (Peak Signal to Noise Ratio) ratio of channel. The signals obtained are defined under a range of programmed and parametric values. This paper poses a scheme of secure data hiding in encrypted images using distributed source coding. After encrypting the original image with a stream cipher, some bits of MSB planes are selected and compressed to make room for the additional secret data. On the receiver side, all hidden data can be extracted with the embedding key only, and the original image approximately recovered with high quality using the encryption key only. When both the embedding and encryption keys are available to the receiver, the hidden data can be extracted completely and the original image recovered perfectly. Index Terms— Reversible data hiding, Signal to Noise ratio, Peak Signal to Noise ratio, Slepian-Wolf encoding, Secure data hiding.
