In this paper, encryption/decryption of color image is proposed by using Linear Canonical Transform (LCT). The color image is to be encrypted, firstly separated into its three primary channels: red, green, and blue and then each channel are encrypted independently using double random phase encoding technique. The parameters which generate the LCT domain during encryption / decryption are considered...
A random phase mask plays a significance role in encryption/decryption of color image. In this paper we are presenting a comparison between chaotic function and different random phase masks, which is used encryption decryption of color images, based on Fractional Fourier Transform (FRT). Random The different fractional orders and random phase masks used during the process of encryption and decryption...
