摘　　要：随着数码相机,数字打印扫描等电子设备的广泛应用,获取数字图像变得十分快捷;随着电子计算机的高速发展,图形图像处理软件功能的日益强大,使得伪造和篡改图像变得十分容易。如果不法分子将伪造和篡改的图像用于法庭证物、保险取证、新闻媒体、科学发现中,将会对社会安全稳定带来极大不良影响,因此对数字图像的鉴定取证技术受到相关人士的广泛关注,具有深远的科学意义和重要的政治价值。本文即针对基于数字水印的图像鉴定取证技术展开了研究,以期推动图像鉴定取证的进一步发展。With digital cameras,digital print scan electronic devices widely used,obtaining digital images become very fast. With the rapid development of computer,graphic image processing software function more powerful,it is easy to forge and tamper images. If the criminals will be forged and tampered with the image for forensic evidence,evidence of insurance,news media,scientific discovery,great adverse effects could be brought on socail safety and stability. So forensic techniques for the identification of digital image receive the extensive concern of the stakeholders,and has profound scientific significance and important political value. According to the aboved,the paper researches on the technology of digital watermarking based on image authentication,for promoting the further development of identification of evidence.
