Hiding of Image using N-Queen Solution Matrix and DNA Sticker
نویسندگان
چکیده
This paper presents a technique of staganography where hiding of secret image done by LSB substitution and N-Queen matrix act as key. Key used to indicate pixel position of Cover image where substitution will take place.Memomy complex (Memory strand and DNA stickers) used to represent N-Queen matrix so that key isn’t understandable to unauthorized user. Size of NQueen matrix relate with no. of bits in Secret Image. To make N-Queen matrix reasonable size, Secret image embed after compression.

Solving N Queen Problem Using Various Algorithms – A Survey
Combinatorial optimization problems form a set of problems which need a considerable effort and time to be solved. Their difficulty lies in the fact that there is no formula for solving them exactly. Every possibility has to be examined in order to find the best solution and the number of possibilities increases exponentially as the size of the problem increases. In this paper we discussed abou...

In this paper, stickers are used to construct a solution space of DNA for the satisfiability (SAT) problem. Simultaneously DNA operations are applied in the sticker-based model to develop a DNA algorithm. The result of the proposed algorithm shows that the SAT problem is resolved with biological operation in the sticker-based model for solution space of sticker. Furthermore, this work presents ...
متن کاملImproving security of double random phase encoding with chaos theory using fractal images
This study presents a new method based on the combination of cryptography and information hiding methods. Firstly, the image is encoded by the Double Random Phase Encoding (DRPE) technique. The real and imaginary parts of the encoded image are subsequently embedded into an enlarged normalized host image. DRPE demands two random phase mask keys to decode the decrypted image at the destination. T...
