Security Mechanism for Image Authentication Based on Pixels Adaption

Information security is a very important and need desperately in the exponential growth of internet technology. Encryption is one among many techniques to secure useful information with help of sensitive keys. In this paper, a logically sophisticated image encryption scheme is proposed which is based on pixel adaption. XOR (Exclusive-OR) and mod operators with a random key generators are the key parameters for Pixel adaption. Performance is being evaluated through histograms. Encryption implementation is evaluated for different images using MATLAB. Reverse process of encryption is Decryption. Experimental results proves that the scheme is highly key dominated and shows a high immune to brute-force and statistical attacks.
