In this paper, confusion algorithm based on three dimension chaotic map system will be proposed and presented. Chen's chaotic system is 3-D chaotic map system, which will be used to obtain a proposed confusion algorithm. A proposed encryption algorithm will be designated as CA3DCS. It will be applied on two different color's frequencies colored-images. A proposed algorithm (CA3DCS), which Contains Confusion procedure based on Chen 's chaotic system is used to shuffle the positions of pixels of the colored plain-image. CA3DCS will be 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 (CA3DCS) is a good algorithm to provides an efficient and secure way for confusing or encrypting the colored images.
