An Efficient and Fast Digital Image Copy-Move Forensic Technique

Digital images consider as an active and natural media for carrying worth information over the world. With the release of high-resolution digital cameras, PCs, and developed photo editing applications, the digital images forgery becomes very popular. Therefore, the need for using the forensic techniques is increased, and the most active research subfield is the copy-move forgery detection. Through many existing techniques, block-based matching strategy provides good results but need to increase the processing time. To cope with this problem, an efficient and fast technique have been designed to detect and identify the digital image copy-move forgery without any prior information concerning the image under analysis. The performance analysis presents that the proposed technique is able to detect the duplicated-regions efficiently, with a minimal processing time.
