摘　　要：造假图像准确识别技术是目前研究的热点。本文利用混沌系统的类随机性和遍历性的特点,采用半脆弱数字水印算法,通过给出水印生成和嵌入方式,将数字水印嵌入到原图像中,并从一部分待识别图像的子块中提取水印特征参数,另一部分嵌入提取的特征水印,通过嵌入原图像的数字水印信息对造假图像进行识别和篡改定位。仿真分析结果表明,该算法可以使正常压缩的图像通过检测,对非正常编辑图像进行有效判定,取得了理想的识别效果。False image accurate identification research was a hot topic at present.This paper used chaotic system＇s characteristics of random ness and ergodicity.A semi fragile digital watermarking technology based on image recognition method of fraud was proposed,the watermark generation and embedded were given,the digital watermark was embedded into the original image.The watermark characteristic parameters were extracted from the part of being recognized image, the other part of image embedded feature watermark which was extracted from the parts.The false image could be recognized and tamper localized by embedding the original image digital watermark information.The simulation results show that the algorithm could make normal compressed image through detecting,non normal edit image effectively recognized,satisfactory results had been botained.
