Resum:	High capacity steganography is still challenging today in the field of information security. The demand for the exact retrieval of the cover media from stego-image after the extraction of secret data is also increasing. Using reversible information hiding techniques, the cover image can be recovered at the time of extraction of secret messages. Two techniques are proposed in this paper. In the first technique, the image is interpolated using a new interpolation technique and the second technique uses a High Capacity Reversible Steganography using Multi-layer Embedding (CRS) method for image interpolation. In both the techniques, the secret data are embedded in the cover image by Exclusive OR (XOR) operation. The proposed techniques give high embedding capacity and preserve image quality. The experimental results show that the proposed techniques offer better results over the existing techniques.
