Image encryption algorithm using chaotic sequences and flipping

Image Encryption is a technique to make the image unreadable. This can be achieved by realigning the pixel value of image or by changing the pixel value of an image. In this paper, an image encryption algorithm has been proposed where pixel value is changed using logistic map (diffusion) and position of pixel value is changed using flipping (confusion). The simulation result shows that encryption algorithm is easy to implement, secure and time efficient.
