Bio-medical Image Encryption Using the Modified Chaotic Image Encryption Method

Abstract

AbstractProtection of personal data from unwanted access while assuring speed and precision is essential in today's information and speed driven world. Recent research on picture encryption methods have increasingly been based on chaotic systems, although in one-dimensional chaotic cryptosystems there are apparent disadvantages of a tiny key space and low security. The chaotic approach has been used to suggest a novel picture encryption algorithm to avoid the aforesaid limitation. A chaotic dynamic mechanism is employed in the synchronization of two chaotic systems and controllers. The picture is cramped by adding the chaotic sequence to the disturbance term associated with the plaintext. Then the dynamic index's cipher text feedback device is adopted at the diffusion stage. This means that the cipher text cipher index utilized to provide feedback is locative indexed. The proposed stenography with the chaotic map technology, as regards the time required to mark a certain collection of images and with greater space, smaller iteration times and high security analysis such as key space analysis, statistical analysis and sensitivity analysis, is simpler and more effective. Image encryption is accompanied with a confused logic to create a secret key. In addition, experimental findings like key space analysis, analysis of key sensitivity, differential analysis, histogram, entropy information and correlation coefficients reveal a safe and reliable image encryption technique with significant potential for application.KeywordsSteganographyChaotic logistic mapImage encryptionChaos shift keyingChaotic maskingSecret key
