Abstract:

To ensure the authenticity and information safety of the image content, application areas of passive forensics techniques are stated. The ideas and main steps of some typical algorithms for digital image source device detection, splicing detection, copypaste detection, blur detection and JPEG (Joint
Photographic Experts Group)compression detection have been analyzed. The algorithm performance and feasibility have been briefly evaluated, and the future technical route and development direction of passive forensics techniques are prospected.

Key words: digital image, passive forensics, source device, splicing, copy-paste, artificial blur, joint photographic experts group(JPEG)compression
