VD Expert is a system for forensic video investigation – a set of professional instruments for video editing detection.
VD Expert is a set of special tools designed to detect video modification during forensic study when the video recording stands as evidence in a case: video stream authentication, revealing changes in the sequence of events or their content, image enhancement, identification of the video recording device.
device's storage examination reveals the features of the data sequences formation/ This allows to establish whether the video evidence was recorded using this device or copied to the storage device from an external source.
includes a detailed analysis of the file header and file structure verifying its compliance with the file format and recording format standards. The frame allocation map reveals the order of frames (and its violations). Metadata analysis reveals signs of editing using specialized software tools.
includes a set of tools for image authentication: collection of filters and research methods that reveal signs and features of image manipulations and editing via video frame images content.
represented by a set of tools that allows to establish the continuity of the recording. Nowadays, this is the most productive way to study video recordings for authenticity - the study of technical characteristics (extracted directly from the video signal) continuity changes. In most cases these technical characteristics are out of video recording operators’ control or the person who edits the original video material. Electrical Network Frequency (ENF) is an example of such a parameter. ENF database is provided by electrical power provider company. Comparison of ENF database and ENF trace extracted from the video signal proves the exact date and time of the recording, as well as its continuity.
includes the research of synchronization between audio and video stream of the evidence. Comparison of video and audio signals behavior reveals traces of editing and manipulation, complementing each other.
includes the recording device analog and digital features analysis by evidence and test video recording comparison. Every approach listed above provides its own contribution into recording device identification: FAT analysis, file header and structure analysis, intra- and inter-frame analysis, inter-stream analysis and PRNU analysis (revealing the individual video recording device matrix characteristics). The unique functionality implemented in VD Expert allows the user to extract and analyze video recording editing traces and to export the results to the expert's report.
