A New Image Scrambling Algorithm Based on Queue Transformation
Haiyan Zhang · 2007
Information security is a hot issue at present. Digital image scrambling can not only be a usual image encryption, but also a pre-progress of digital watermark and image hiding. It is an important thesis. There are many image scrambling algorithms. Image scrambling algorithm based on queue transformation is a good method. But it has many disadvantages. So a new image scrambling algorithm based on queue transformation is proposed in this paper. This algorithm only needs one step instead of two steps to complete the scrambling. Meanwhile, reference point can change in every stage. If the attackers want to decode the hiding image, the step, the reference point and the direction should all been known. So it is difficult for the attacker to decode.
