Abstract: Considering blindness in information security, image scrambling method is defined as a procedure by which an image is turned into an absolutely different meaningless image through a reversible transformation. By scrambling an image, the ability to resist against unauthorized attacks and accordingly, augmenting security can be obtained effectively. In this approach, a quantum representation of a digital scrambling algorithm is investigated for quantum NCQI color images. Experimental consequences encompassing histogram diagram, entropy rate, correlation coefficient and number of pixels change ratio, which are analyzed in MATLAB environment, indicate a good performance, showing that the proposed method is much more secure and applicable than the previous one currently found in the literature related to the quantum image disordering methods.
