ENF Signal Extraction for Rolling-shutter Videos Using Periodic Zero-padding

Abstract: 

Electric Network Frequency (ENF) analysis is a promising forensic technique for authenticating digital recordings and detecting tampering within the recordings. The validity of ENF analysis heavily relies on high-quality ENF signals extracted from multimedia recordings. In this paper, we propose an ENF signal extraction method for rolling shutter acquired videos using periodic zero-padding. Our analysis shows that the extracted ENF signals using the proposed method are not distorted and the component with the highest signal-to-noise ratio is located at the intrinsic frequency. The experimental results show that our proposed method can generate more precise ENF signals than those from the state-of-the-art method.
