摘要：

About the problem that the lower localization accuracy and the higher false alarm rate in the conventional quantization-based approaches, we proposed a semi-fragile watermark scheme for analyzing the tampered localization accuracy of existed mean-quantization. The probabilities of tamper detection and false alarm caused by area tampering in mean-quantization approaches will be, respectively, maximized and minimized by statistical analysis. The proposed scheme not only effective analyzes the tampered localization of the mean-quantization algorithm, but also made an objective evaluation index to quantitative analyze the performance of the authentication watermarking.
