“…Steganography [23]: Instead of embedding the secret information directly into the cover image, image realization has been proposed in this paper. Embedding of some mapping information related to the secret information into the cover image is done using Matrix Encoding Technique and the realization of the secret is done using a highly secured pass key.…”

“…Mapping of secret message, key generation and the embedding are done in the first phase followed by the extraction procedure in the next phase. One of the planes (red plane in [23]) of RGB image is used for creating the mapping matrix. The selected plane (C i ) is represented as the multiples of secret image and divided into different blocks.…”

“…The size of the secret information and the location of the matrix are extracted from the key and the retrieval of secret information is done by finding the difference between the matrix got from the key and the original matrix value. This technique is secure against Brute Force attack since the decoding key has a sufficiently large key space [23]. High securities against statistical attacks as well as histogram attacks are also the achievements of this method.…”

Steganography is the technique of hiding data in an appropriate multimedia carrier, e.g., image, audio, and video files known as Cover. Images are mostly used as the cover medium due to their pervasiveness in different applications and representation with high redundancy. This paper provides a review and analysis of many existing methods for digital image steganography in the spatial as well as transform domain. The performance evaluation of the algorithms with respect to the proposed analysis parameters are summarized along with their limitations inorder to throw some light on the utility of the algorithm as per the requirement of application.

Image Realization Steganography aims in devising techniques that realize a secret message from a cover image using a suitable cover-to-secret mapping with low embedding rates. This paper presents an Image Realization Steganography technique which maps a secret image as a Longest Common Subsequence of a given cover image. The cover image being a string of high degree of randomness and a very large length as compared to the secret image, the length of the LCS between them is expected to be close to the length of the binary string equivalent of the secret image. This enables the proposed technique to realize a secret image with very little or no modification of the cover. Experimental results validate this fact strongly. The results also indicate that any given cover image can be used to realize a secret image as large as itself thereby establishing the high hiding capacity of the technique.

“…As an alternative, a reversible reduction mapping capable of regenerating the payload in presence of a suitable decoding key can be considered to be a viable solution. Steganography techniques using map based realization are termed as Image Realization Steganography [11,12]. Parallel beam projection [13] of an image payload is observed to fulfill the requirements of such a mapping scheme.…”

Steganography techniques find importance in military applications because of their ability to communicate covertly. It is evident for any image steganography technique that if the payload can be represented in a smaller dimension than its original form, then the actual embedding requirement can be lessened thereby improving the statistical imperceptibility of the method. This paper presents an image steganography technique specifically aimed to be used for military covert communication which utilizes payload dimension reduction using parallel beam projection of images. Efforts have been given to ensure that the proposed technique conforms to high Imperceptibility and Fidelity which are the primary quality requirements for any image steganography system.
