ENF-EXPERT is a powerful forensic audio and video evidence authentication tool.
By expert experience Electrical Network Frequency pick-up is present in every third case of audio and video forensic examination. ENF pick-up is conducted by electro-magnetic influence of electric power supply network or any electronic equipment on the analogue chain of the audio and video signal recording.
Electrical Network Frequency is changing slightly during time as different network customers are joining or leaving the net. ENF change has always individual behavior and cannot be predicted. The ENF database keeps historical values of the mains frequency value and can be used for the search of the ENF trace extracted from the audio/video evidence matching to the certain period of time. If there is a match the audio/video evidence continuity and exact date and time of the recording can be verified standing as a proof of its’ authenticity.
ENF-TRACKER is the hardware equipment developed for the purposes of ENF database collection using precise measurements.
Metal shielded box reduces the impact of any other EM interferences. The system is compatible with all types of mains plugs, voltage and frequency parameters of local electric grid.
ENF-SERVER is the software part of ENF database collection and management. ENF measurements precision is 0.001 Hz. ENF-SERVER allows to navigate through the database and provides real-time ENF visualization over dynamic spectrogram.
ENF-EXPERT can be a module of VD-EXPERT or TD-EXPERT or a standalone application that extracts the ENF trace from audio or video signal of the media evidence and runs the search of the extracted ENF evidence pick-up through the ENF database, proving the exact date and time of the recording and verifying signal continuity.
