In this paper, a novel chaotic fingerprint images encryption scheme is proposed combining with shuttle operation and nonlinear dynamic chaos system. Firstly, a new image total shuffling operation is employed to shuffle the positions of image pixels in the spatial-domain. Then the discrete output signal of the nonlinear dynamic chaos system is preprocessed to confuse the relationship between the shuttled image and the cipher-image. The results of several experimental, statistical analysis and key sensitivity tests show that the proposed image encryption scheme provides an efficient and secure way for fingerprint images encryption and storage.
