Abstract
OCML chaos systems to encrypt the iris identify code,and compound chaos encryption system(CCES)which combines Arnold transform and OCML,to encrypt iris image were proposed.Arnold transform was used to shuffle and confuse iris image,and utilize mirrored way to proceed the question of zero position invariable.The encryption operation was fininshed by OCML chaos system.The results show that the algorithm has such advantages:larger key space,better key sensitivity and better statistical characteristics,and the average encryption time is 70 ms.
