Description: Digital images are the most prevalent way to spread a message. So the authenticity of images is very essential. But due to advancement of the technology the editing of images has become very effortless. Copy-move forgery is most basic technique to alter an image. In this one part of image is copied, called as snippet, and pasted within same image and most likely post-processing it. Considerable number of algorithms is proposed to detect different post-processing on snippet of image. In this paper novel approach is proposed to detect combination of different post-processing operations by single method. It is analyzed that block-based features method DCT is robust to Gaussian noise and JPEG compression, secondly the keypoint-based feature method SIFT is robust to rotation and scaling. Thus by combining SIFT and DCT we are able to detect forgery under post-processing operations of rotation, scaling, Gaussian noise, and JPEG compression and thus the efficiency to detect forgery improves.

Description: SIFT算法大致有四个步骤:
1，尺度空间极值检测。在尺度空间通过高斯微分函数来检测潜在的对于尺度和旋转不变的兴趣点。
2，关键点定位。在兴趣点位置上，确定关键点的位置和尺度。3，方向确定。基于图像局部的梯度方向，给每个关键点分配方向。4，关键点描述。在每个关键点的领域内测量图像局部的梯度。最终用一个特征向量来表达。-SIFT algorithm roughly four steps:
1, the scale space extremum detection. In the scale space to detect potential points of interest for the scale and rotation invariant differential by a Gaussian function.
2, the key point positioning. In point of interest position, determine the location and scale of key points. 3, to determine the direction. Based on local gradient direction, the direction assigned to each key. 4, the key point description. Local image gradient measurements within each key field. With a final feature vector to express.
