Abstract
This paper studies an observer-based finite-time scheme for two modified projective synchro nization modes, including the synchronization of multiple uncertain chaotic response systems to one drive
system and transmission synchronization. First, a finite-time super-twisting observer is designed to estimate
the uncertain terms. Then, a finite-time controller is proposed to guarantee the chaos synchronization, and
the numerical simulations illustrate the efficiency and robustness of the proposed strategy. Finally, the appli cations based on chaos synchronization which include masking encryption and secure communication of the
color image using DNA encoding are validated
