Abstract: This paper presents two kinds of methods of digital image scrambling, the quasi-anti-order scrambling and quasi-dither scrambling. The effectiveness of these two kinds of methods is discussed according to the gray value space of digital image. Experimental results show that these two kinds of methods are valuable in the field of secret image storage and transmission.
