A simple image encrypting algorithm based on permutation by number theoretic application is presented .The original image can be retrieved without any loss in the spatial domain by using some keys. The schemes are especially useful for encryption of large amounts of data, such as digital images. This method is very easy to implement. It has a remarkable level of security against the full search attack for cryptanalysis.
