Blended Vector Matrix On Different Channels Of Image Encryption With Multi-Level Distinct Frequency Based Chaotic Approach To Prevent Cyber Crimes By Using Affine Transformation

摘要

Security attacks through Internet has proliferated in recent years. Henceforth, information security is a challenge of very serious global concern of the present time. The protection of image data from unauthorized access is very essential. Encryption methods are exceptionally valuable tools to secure secret data. In this work a Effective secret communication using image encryption based on affine transformation has been proposed. The multimedia encryption method which has partial encryption capability, very slight bit-rate overhead, acceptable security level and also which is robust to the lossy compression. Embracing diverse cryptographic algorithms in modern digital communication frameworks utilizing an assortment of techniques ensures confidentiality. These communications were military by nature, however today with the expansion of individual communication frameworks; communication secrecy has value in military as well as civilian communication scenarios. Digital encryption is the main element to ensure the secure transmission of a message. To overcome information security issue presents an effective secret communication in preventing cyber crimes using affine transformation in this work.
