The security is an important issue in watermarking. It has not, however, received enough attention yet. In this paper, we propose a secure fragile watermarking algorithm based on parameterized integer wavelet transform, and the rational range of the parameter is derived theoretically. Without the parameter of the wavelet base used for watermarking, it is hard for attacker to recover or attack the hidden watermark. Multi-resolution tamper detection is developed for the accurate detection. Both security and lower computational complexity of the generated fragile watermark are achieved.
