Encryption Algorithm of Colored Watermark Image Based on Arnold Transform and Lorenz Chaos System
|
Abstract:
This algorithm uses the Arnold transformation and the color image scrambling definition, to solve the Lorenz chaos system's dynamic equation, to obtain three chaos sequences. Then it carries on scrambling processing after Arnold scrambling's each color component. The simulation experiment result indicated that this algorithm has overcome the Arnold transformation and the Lorenz chaos system's shortcoming, can resist many kinds of attacks, enables the high security of the colored watermark image.
