“…Here, we consider the efficiency of a data hiding scheme to be based on two main factors, those are embedding capacity of the cover image and quality of its stego image [15,18,29]. Our schemes are the near optimal data hiding scheme (2,9,8) for gray and palette images with q color = 3, and the optimal data hiding scheme (1, 2 1, ) n n − for palette images with q color = 1.…”

“…where ( , ), ( , ), ( , ), ( , ), ( , ) B i j G i j R i j B i j G i j ′ ′ and ( , ) R i j ′ are the color value of the Blue, Green and Red components of a pixel at position ( , ) i j in the cover and stego image, respectively. For human's eyes, the threshold value of PSNR value is 30dB [8,15,18,29], it means that the PSNR value is higher than 30dB, it is hard to distinguish between the cover image and its stego image.…”

“…In addition to the three main factors, speed of the embedding and extracting functions also plays an important role in steganographic schemes. It is considered as a last constraint to determine efficiency of schemes [11,15,18,20,24,29].…”

In this paper, we introduce concepts of optimal and near optimal secret data hiding schemes. We present a new digital image steganography approach based on the Galois field () m GF p using graph and automata to design the data hiding scheme of the general form 2 (, , log) mn k N p     for binary, gray and palette images with the given assumptions, where , , , k m n N are positive integers and p is prime, show the sufficient conditions for the existence and prove the existence of some optimal and near optimal secret data hiding schemes. These results are derived from the concept of the maximal secret data ratio of embedded bits, the module approach and the fastest optimal parity assignment method proposed by Huy et al. in 2011 and 2013. An application of the schemes to the process of hiding a finite sequence of secret data in an image is also considered. Security analyses and experimental results confirm that our approach can create steganographic schemes which achieve high efficiency in embedding capacity, visual quality, speed as well as security, which are key properties of steganography.

<span lang="EN-US">Compression and encryption of speech signals are essential multimedia technologies. In the field of speech, these technologies are needed to meet the security and confidentiality of information requirements for transferring huge speech signals via a network, and for decreasing storage space for rapid retrieval. In this paper, we propose an algorithm that includes hybrid transformation in order to analyses the speech signal frequencies. The speech signal is then compressed, after removing low and less intense frequencies, to produce a well compressed speech signal and ensure the quality of the speech. The resulting compressed speech is then used as an input in a scrambling algorithm that was proposed on two levels. One of these is an external scramble that works on mixing up the segments of speech that were divided using Fuzzy C-Means and changing their locations. The internal scramble scatters the values of each block internally based on the pattern of a Sudoku puzzle and quadratic map so that the resulting speech is an input to a proposed encryption algorithm using the threefish algorithm. The proposed algorithm proved to be highly efficient in the compression and encryption of the speech signal based on approved statistical measures.</span>
