Fractional order Liu-system synchronization and its application in multimedia security

This paper proposed a method to achieve the projective synchronization of fractional order Liu-system. Based on constructing an approximation integer order system for the fractional order Liu-system, a control algorithm is proposed to improve on the projective synchronization in the new integer order systems. The synchronization method is adopted to realize the generalized synchronization of 2.7 order Liu-system, and the simulation result verify the effectiveness. This control scheme can be used in some multimedia security and information transmission based on Internet.
