Binary decomposition-based image cipher algorithm with flexible method for key construction

<span>Image security is still one of the important fields in multimedia processing because it’s used our daily lives. Watermarking, steganography, and ciphering are three directions to keep an image secret. Encryption defined as process changing information (which called plaintext) into unreadable secret format cipher-text). A new algorithm based on binary decomposition codes conversion proposed this paper. The key constructed a flexible way size using some logical operations increase levels. Three test images different sizes were evaluate performance algorithm. results visual scene statistical factors proved that suggested method was with high security. work validated confirm its effectiveness. As conclusions, uses simple have given high-level Also, construction step face several types attackers.</span>
