Recently, reversible data hiding (RDH) techniques for JPEG images have become more extensively used to combine image and authentication information conveniently into one file. Although embedding data in JPEG image degrades visual quality and increases file size, it is proven to be useful for data communication and image authentication. In this paper, a data hiding method in JPEG image using a new coefficient selection technique is proposed. The proposed scheme embeds data using the histogram shifting (HS) method. According to the number of zero AC coefficients, block ordering is used to embed data first in the blocks causing less distortion. In order to further reduce the distortion, positions of AC coefficients are selected carefully. Finally, AC coefficients valued +1 and −1 are used for embedding, and the remaining non-zero AC coefficients are shifted to the left or right directions according to their sign. Compared to the current state-of-the-art method, experimental results show that the proposed method has higher peak signal to noise ratio (PSNR) and smaller file size.

“…However, there are other approaches that aim the modification of parameters such as: most insignificant bit [17], unused bits from files' headers [8], minor modifications of the compression level [20](in case of compressed files, especially multimedia ones), minor modifications of the content (the carrier itself), various conventions (such as: even length means "1", odd length means "0"). These techniques do not require a very complicated theoretical background nor high computational resources.…”

“…Digital steganography is a generic definition for all techniques that make possible the inclusion of various forms of information (text, image, video [3]) into various formats of carrier containers (static image or text files, video or sound files, network headers and other). Many studies [12], [13], [20] reveal the fact that multimedia files are preferred when steganography is implemented. This choice is based on particular characteristics of multimedia files [11], [16] that allow embedding information without a visible impact or modification of the carrier [17], [19].…”

For some people a science, for other people just an art, steganography is in fact an ancient method of embedding a message into an apparently uninteresting carrier. Aiming to protect information, steganography is considered to be a close relative of encryption although they have different approaches. While encryption scrambles the message based on a certain algorithm so it can't be understood by anyone that does not hold the unscrambling key, steganography works on hiding the message without the need to deteriorate it. Minor alteration of the carrier file is accepted since steganography does not affect its useful content. Actually, steganography exploits file redundancy, file headers or, in case of multimedia content, replaces information that can't be used or perceived by the human eyes or ears. In this paper, a combination of image based steganography with encryption is presented. The encryption and decryption are based on two different files in which, by steganographic means, important information is hidden. The original message (the secret message) can be restored only if both files arrive safe at destination. There are no constraints regarding the image file types. The most important contribution resides in how the original information is encrypted and embedded into different graphic files, sent to the destination through different channels and then restored. Comparative performance tests were performed.
