A survey of passive technology for digital image forensics

Frontiers of Computer Science, 2007
Over the past years, digital images have been widely used in the Internet and other applications. Whilst image processing techniques are developing at a rapid speed, tampering with digital images without leaving any obvious traces becomes easier and easier. This may give rise to some problems such as image authentication. A new passive tech- nology for

Passive Forensics Method to Detect Tampering for Double JPEG Compression Image

2011 IEEE International Symposium on Multimedia, 2011
A passive forensics method to detect tampering for double JPEG compression image is proposed. In the proposed method, inconsistency of quality factors is used to detect double JPEG compression, and then a passive forensics approach to detect tampering and locate tampered area for tampered JPEG images is proposed.

A MCEA based passive forensics scheme for detecting frame-based video tampering

Digital Investigation, 2012
Without the use of digital signature or digital watermark, video passive forensics only utilizes the statistical characteristics of digital video to verify its integrity and authenticity. For frame-based video tampering, it usually suffers from double MPEG compression.

A DWT-DCT Based Passive Forensics Method for Copy-Move Attacks

2011 Third International Conference on Multimedia Information Networking and Security, 2011
A passive forensics method for detecting copy-move attacks was proposed. In the proposed method, tested image was segmented into non-overlapping blocks, DCT and DWT are applied to each image block to extract features, and then compare the statistics of each image block to detection replication regions.
