Abstract

Over the years, large amount of transferred information has been attacked by hackers; so it has been considerable to make all effort for securing data and encrypting the information. Color images represent a very vital and important type of multimedia; so many encryption techniques have been proposed to protect the color image against different types of attacks. In this paper two proposed techniques will be introduced which have had high robustness against complex composite form of attacks. Discrete Wavelet Transform (DWT) has been applied for image transformation in one method and Discrete Cosine Transform (DCT) has been applied in the other one. Six various chaotic maps have been used with different parameters to introduce the needed encryption keys for the proposed approaches. After many extensive comparisons with other traditional techniques it has been found that the proposed algorithms have given better performance against both friendly and hard forms of complex composite attacks.
