Abstract:

This article proposes an encryption image algorithm possibly called the stream of modified Image Encryption to verify secure image transmission requests. This algorithm is based on the symmetric key encryption method. The system uses a neural network (NN) based pseudo-random number generator with back-propagation learning algorithm. This will provide the necessary nonlinear properties that increase the statistical properties of the pseudo-random generator randomness. The results of the computer simulation based on the MATLAB simulation were performed to demonstrate the effectiveness of the learning process to obtain the effective weights. The results also show several experimental and statistical analyzes to demonstrate the randomness of the pseudo-random generator as well as the proposed image encoding and decoding. The result reflects a simple and effective image security system.
