摘　　要：随着图像篡改伪造技术的迅速发展，基于数字水印和数字签名的数字图像主动取证技术由于受到应用条件的限制，已经无法从根本上遏制图像篡改伪造的步伐，因此数字图像被动盲取证技术就成为取证技术研究的重点。本文详细的给出了数字图像盲取证技术的发展全貌，并根据不同的图像篡改类型，深入分析了不同取证技术的数学思想与算法原理，同时对各种取证技术的优缺点进行了对比总结，最后本文对数字图像盲取证技术的发展前景进行了展望。With the rapid development of image tampering technology, the active digital image forensics which is based on digital watermarking and digital signature technology has not fundamentally suppress the pace of image tampering, so the passive digital image forensics has become the focus of the research. This article gives a whole and detailed description of digital image forensics technology. In the meantime, depending on the different kinds of image tampering, we show the different mathematical thinking of forensic technology and algorithm theory in-depth analysis, while the advantages and disadvantages of various forensic techniques were compared. Finally, we draw the conclusion on the prospect of passive digital image forensics.
