A Secure Data Embedding Technique In Image Steganography For Medical Images

Abstract: Steganography is an art and science of secure information communication where the secret data or confidential data is hidden in host file. It is used in different useful applications like secure data communication, healthcare and military. Confidential information’s are commonly stored in digital media and transmitted via internet due to the rapid growth of internet. If the information’s in images are altered then this may lead to wrong assumptions. Certain medical applications require information exchange over an insecure network where a small piece of medical information is modified intentionally for certain illegal purpose which may lead to wrong diagnosis. Therefore protection of integrity, reliability and confidentiality of the secret medical data in images are the important issues. To protect the secret medical information cryptography technique can be used where the secret medical data is altered, even if the attackers get to know the data it won’t be of any use without knowing the algorithm. According to the survey not all issues are satisfied by the single method. In this paper a brief introduction is presented later related works followed by proposed algorithm, results and conclusion.
