With the fast progression of data exchange in electronic way, information security is becoming more important in data storage and transmission. Because of widely using images in industrial process, it is important to protect the confidential image data from unauthorized access. In this paper chaos based image encryption algorithm utilizes the good features of chaotic sequence related to cryptographic properties, such as pseudo-random, sensitivity to initial conditions and aperiodicity. The logistic mapping is used to generate chaotic matrix which is used to scramble the location of pixels in a digital image.
