- W2381752385 abstract "A quantization-based semi-fragile watermarking algorithm for digital image content authentication is proposed. The algorithm is robust to incidental manipulations while fragile to malicious distortions. The tampered area of the watermarked image can be reflected in the watermarking difference map and a running window after the watermarked image is processed by common manipulations. The formulation of judging threshold is given from the point of probability theory. Experimental results show our semi-fragile watermarking algorithm is effective and practical for content authentication." @default.
