Abstract :
With an abridged introductory note on the discrete wavelet transform (DWT) and random shift cipher (RSC), this paper attempts to study a technique for color image encoding and decoding scheme using two stage random shift cipher (TSRSC) associated with DWT. In this approach, keys and the arrangement of RSC parameters are compulsory. The formula for total number of keys in encoding process of color image is given. The capability of this proposed technique can be analyse by conclusion.
