Steganography, which means “covered writing” in Greek, is the art and science of
invisible communication. It is employed in various useful applications, e.g., copyright control of
materials, companies‟ safe circulation of secret data, and in Medical Imaging Systems.
Steganography can be achieved by hiding information in cover media. For most of the current
steganography techniques, the information hiding process modifies almost all cover components. In
this paper, a new method of steganography within digital images is presented. The method is a
characteristic region based steganography using Speeded-Up Robust Features technique (SURF).
The proposed technique embeds the binary secret message into the more robust characteristic
regions in transform domain. Steganography synchronization is first achieved by the characteristic
regions, which can be extracted using SURF technique, and then data embedding is achieved in a
content based manner by modifying the wavelet transform coefficients. Experimental results show
that the proposed algorithm allows hiding data invisibly with an accurate retrieval in the presence of
lossy compression. In addition, the scheme is robust to noise interference.
