Adaptive Circular Queue Image Steganography with RSA Cryptosystem

Publication date: Available online 3 May 2016 Source:Perspectives in Science Author(s): Mamta Jain, Saroj Kumar Lenka, Sunil Kumar Vasistha The major objective of the article is to supply the novel and efficient methodology of digital image steganography that describes individuality regarding secret transmission using the adaptive circular queue least significant bits (LSBs) substitution. The data structure queue is employed dynamically in resource distribution between multiple communication recipients and once secret information transmitted asynchronously. Here, RSA cryptosystem is employed for secret information confidentiality and authentication. The result of the cryptosystem organized into various blocks. In steganography method, organize the cover image into various circular queues blocks. Dynamically adapted procedure is employed to assign secret cipher blocks to circular queues for embedding. Authorized receiver will determine the right plain text using private key in RSA decipherment. Performance analysis is evaluated by using MSE, PSNR and maximum embedding capacity. Results are higher as compared with several of existing algorithms of image steganography.
