Summary:
The estimation of location based on the time varying Electric Network Frequency (ENF) is a new emerging technology in Information Forensics. This requires the extraction of the ENF signal from multimedia recordings and a comparison with already known power grid signatures. In this paper, we focus on ENF signal extraction and statistical modelling of ENF signals. We introduce a novel technique based on instantaneous frequency estimation using the Hilbert transform, which shows promising results.
