Abstract—This paper introduces a proposed confusion algorithm based on Chen's chaotic system. Chen's chaotic system which used to obtain a proposed confusion algorithm is three dimension chaotic map system. A proposed encryption Algorithm is designated as PCACHS. It is applied on two different color's frequencies colored-images. A proposed algorithm (PCACHS) is used to shuffle the positions of pixels of the colored plain-image. PCACHS is applied on all color's channels of the image; Red, Green, and Blue. The expectant results of several experiments, statistical analysis, key sensitivity tests, and information entropy analysis will show that the proposed confusion algorithm (PCACHS) is a good algorithm to provide an efficient and secure method for confusing or securing colored images.
