A Novel Biometric Image Integrity Authentication Using Fragile Watermarking and Arnold Transform

摘要：

A fragile watermarking scheme based singular value decomposition(SVD)and Arnoid transform is proposed for the integrity authenticatiOn of biometric images via computer network.We exploit singular values of singular value decomposition of biometric images to check the integrity of biometric images.In order to make authenticatiOn data.the singular values are changed to the binary bits using modular arithmetic.The binary bits of authenticatiOn data are embedded into the least significant bit(LSB)of the original biometric image.The pixels to be changed are randomly selected in the original biometric image.The advantages of this scheme are that 1)we can detect any modification of watermarked biometric images,2) the quality of watermarked biometric images is very high because only a feW bits of authenticatiOn data are embedded.ExperimentaI results show that the proposed fragile watermarking scheme can be applied to the integrity authentication systems based on biometric image.
