For real time secure image transmission over internet and through wireless network, many image encryption schemes have been studied. Main issue is to secure the image from the attacker. Major approach for protecting the image is encryption. There are many image encryption techniques. Chaotic algorithm has many properties like sensitivity to initial conditions on these which makes very desirable for encryption. Many researchers proposed image encryption algorithm based on low dimension chaotic functions, 2D. Here, due to many disadvantages, the 3D encryption algorithm was developed. For large image, data encryption standard is not suitable because of low level efficiency. With the advantages of high level efficiency, chaos based encryption used the 1D chaos system as logistic map, and also 2D chaotic, that is Arnold catmap is used. 1.
