%X In order to authenticate an image,a fragile watermark scheme based on parity of pixels is proposed. In the proposed method, some pixels are selected. Bit information of the watermark is embedded by judging and adjusting the parity of pixels. According to the extracted watermark, we can authenticate the tested image and locate the illegal modification. Experimental results show the proposed scheme has some advantages such as security, high sensitivity and exactly locating the modifications, while still keeping high quality of the image.
