In this paper, we analyze the problems of vulnerability in the original multi chaotic systems-based image encryption scheme proposed by Huang and Nien [Optics Communications 282(2009) 2123-2127]. A selfsynchronizing method is proposed as enhancement measures to solve the problems and defeat cryptanalysis. Theoretical analysis and computer simulation indicate that the proposed encryption scheme is much more secure than the original one. At the same time, it holds the merits of the original scheme.
