In this paper, an algorithm for image encryption using chaotic systems and techniques to change the pixel values are proposed for protecting digital images in an efficient and safe manner will be offered. In the proposed algorithm, the stochastic properties of chaotic Logistic system is used. To evaluate the performance of the proposed algorithm, we have implemented it in MATLAB using parameters such as visual analysis, key space analysis, histogram analysis. Implementation results show that the proposed algorithm, the algorithm is efficient and safe.
