Abstract
Summary 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 organised into various blocks. In steganography method, organise the cover image into various circular queues blocks. Dynamically adapted procedure is employed to assign secret cypher blocks to circular queues for embedding. Authorised receiver will determine the right plain text using private key in RSA decypherment. 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.
