Abstract
The paper presented a method of digital image scrambling based on binary tree generated by chaotic sequences. First, conservative chaos system is iterated to produce chaotic sequences after given initial value and parameters. Then, binary tree is generated by chaotic sequences according to certain rule. At last, the order received by inorder traversing the binary tree is used to transform order of pixels. In this method of digital image scrambling the secret key is initial value and parameters. This method is flexible to use because the secret key is separated from algorithms. It remedies inadequateness of flexibility in other algorithms merely adopting fixed binary tree. Some evaluation indexes show that the method has good effect of image scrambling.
