Inter frame Video Duplication Forgery Detection: A Review
Identifying inter-frame forgery and tampering a video is a challenging topic in video forensics. Tampering involves falsification with video content in order to cause damage or make unauthorised modification/alteration. These tampering impacts need to be studied. Till now the studies employed a video authentication method that detects and determines both frame duplication and region duplication...
متن کاملAn Improved Fingerprinting Algorithm for Detection of Video Frame Duplication Forgery
Frame duplication is a common way of digital video forgeries. State-of-the-art approaches of duplication detection usually suffer from heavy computational load. In this paper, the authors propose a new algorithm to detect duplicated frames based on video sub-sequence fingerprints. The fingerprints employed are extracted from the DCT coefficients of the temporally informative representative imag...
متن کاملVideo Inter-frame Forgery Identification Based on Optical Flow Consistency
Identifying inter-frame forgery is a hot topic in video forensics. In this paper, we propose a method based on the assumption that the optical flows are consistent in an original video, while in forgeries the consistency will be destroyed. We first extract optical flow from frames of videos and then calculate the optical flow consistency after normalization and quantization as distinguishing fe...
متن کاملInter-frame Video Forgery Detection Based on Block-Wise Brightness Variance Descriptor
Video forensics becomes more and more important than ever before. In this paper a new methodology based on Block-wise Brightness Variance Descriptor (BBVD) is proposed. It is capable of fast detecting video inter-frame forgery. Our proposed algorithm has been tested on a database consisting of 240 original and forged videos. The experiments have demonstrated that the precision rate is about 94....
متن کاملVideo Inter-Frame Forgery Identification Based on Consistency of Correlation Coefficients of Gray Values
Identifying inter-frame forgery is a hot topic in video forensics. In this paper, we propose a method based on the assumption that the correlation coefficients of gray values is consistent in an original video, while in forgeries the consistency will be destroyed. We first extract the consistency of correlation coefficients of gray values (CCCoGV for short) after normalization and quantization ...
