Reversible (lossless) data embedding (hiding) has drawn lots of interest recently. Being reversible, the original cover content can be completely restored. This paper proposes a novel reversible data hiding scheme with a lower computational complexity and can be used in applications where both the image and the hidden information is highly confidential. It consists of three phases - AES image encryption, data embedding and data extraction/image-recovery phases. Here, the encrypted image is made highly secured by using an AES (Advanced Encryption Standard) stream cipher.
