Design and Implementation of a cryptographic system for images using Random number generator

Abstract

In the present work the design and development of ciphering method on
colored images is studied. The method use incryption keys for ciphering and
deciphering, where a random number generation program is used to produce a
set of values that determine the incryption keys. In that mid point circles
generating algorithmis used to locate a number of interrelated circles so as to
determine the pixels to be ciphered.
