由于現(xiàn)今功能強(qiáng)大的圖像編輯軟件很容易就可以得到，所以對數(shù)字圖像進(jìn)行操作和編
輯變得非常的容易，在一幅圖像中添加或移掉一個重要的人或物并且不留任何痕跡是很有可能的。如果這些篡改圖像用在媒體或法律上，對社會將造成很大的影響。隨著數(shù)碼相機(jī)和攝像機(jī)的不斷普及，驗證數(shù)字圖像變得越來越重要了。文章利用數(shù)碼相機(jī)的兩個固有特性對圖像進(jìn)行篡改檢測，對多幅圖像進(jìn)行操作，實驗證明有不錯的檢測效果。

Abstract: Digital images are easy to manipulate and edit due to availability of powerful image
processing and editing software. It is possible to add or remove important features from an image without leaving any obvious traces of tampering. These forgeries, if used in the mass media or courts of law, can have an important impact on our society. As digital cameras and
video cameras replace their analog counterparts, the need for authenticating digital
images becomes more and more important. This article uses two inherent attributes of the
digital camera to detect the forgery. The performance of the proposed method is demonstrated on several forged images and has been proved to have good effect.
