Pretreatment Watermark Based on Chaos and Arnold Scrambling Technology

Xu Min Sun Ying (Suzhou Vocational University Suzhou 215104)  
Pretreatment watermark was the first pivotal step in the process of dealing with the watermark.Making use of scramble technology can enhance secrecy and safety..Arnold scramble algorithin is simpleness and feasible,while chaos scramble technology can enhance anti-jamming of watermark.In this paper,pretreatment robust watermark and fragile watermark by Arnold scrambling,and chaos technology are introduced particularly.
