| Abstract | In this paper, a new method has been presented by which an image can be effectively encrypted. Image encryption is a method of encoding a message so that eavesdroppers cannot read the information, only the authorized person can be able to decode the message. In this paper dual transformation is being used one is discrete wavelet transform (DWT) and another is the discrete Fourier transform (DFT). Instead of using Discrete Fourier transform twice different transform is used so that is can be more secure. Before the application of transform, a random phase encoding is done on the image signal by generating a random phase matrix between some range. It is very useful in secure multimedia communication. |
