“…The information can be hidden in many ways in images. To hide information, secret message insertion may encode every bit of information in the image or selectively embed the message in noisy areas, which draw less attention [15], [23]; those areas where there is great deal of natural color variation. The message may also be scattered randomly throughout the image.…”

Steganography is one of the vital topics in the field of information security. In this paper we propose, a new Steganography algorithm that generates and brings out steganographic secret information hidden in images. In the proposed algorithm, the cover image is partitioned into four non overlapping blocks and the confidential data bits are also divided. The data bits are embedded in scattered way into the four blocks. In each pixel either single colour channel or two colour channels are used to embed the confidential data bits depending upon the size of the data bits. The proposed method generates low MSE value and high PSNR value. The experimental outcome shows, the algorithm can overcome drawbacks of many existing algorithms.

“…These approaches can be implemented with or without a key. The approaches like using raster and random scan, space filling schemes [15] like Moore, Hilbert, pixel indicator [14,18]and MSN randomization [19] etc. fall under randomization techniques.…”

“…But this system cannot forestall the unintended users to identify the transmission of message. STEGANOGRAPHY [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19], a sib of the previous technique evolved later which hides the message in unsuspicious cover and provides better security by making the communication invisible. In fact the term steganography in linguistic form is in use centuries ago which cites the usage of Invisible inks, wax tablets etc [17].…”

Digital data protection turns out to be the most essential constituent in the cyber world where digital crime is mounting to its worst. To establish secured data communication a technique called Steganography, one of the fruitful attempts for data hiding, has evolved. The rationale of this scheme is to blot out the message in to an innocuous cover media. For good stego system imperceptibility, randomization and capacity are the important considerations. In this paper we propose a novel keyless random algorithm in image steganography which induces an enhanced security by incorporating "counting-out" embedding. It uses message bits embedded in the current pixel which acts as a key for the next pixel to which data is to be embedded. This method provides adaptive randomization without affecting the imperceptibility and capacity.

“…for effective image steganography. Therefore most steganographic methods [1,2,3,4] focus on these requirements, and the embedding and extracting algorithm etc. In steganograpahic system, however, the receiver, who received the massage, wants to know whether the extracted message has integrity or not.…”

“…In addition to that, the proposed method is able to verify the integrity of the secret information extracted from stego image. Our system is to add a module that verifies the integrity on our previous steganographic method [4].…”

Abstract:We propose a novel steganographic system that is able to provide a high quality stego image in spite of the high capacity of the concealed information. The number of insertion bits in a pixel is different according to each pixel's characteristics. In addition to that, our system is able to verify whether if the secret information was sent from the sender correctly or if an attacker forged the secret message. We use two frequency coefficients in DCT domain to generate the symbol code to check the integrity of secret information.
