ENF Extraction From Digital Recordings Using Adaptive Techniques and Frequency Tracking

  title={ENF Extraction From Digital Recordings Using Adaptive Techniques and Frequency Tracking},
  author={Ode Ojowu and Johan Karlsson and Jian Li and Yong Liu},
  journal={IEEE Transactions on Information Forensics and Security},
A novel forensic tool used for assessing the authenticity of digital audio recordings is known as the electric network frequency (ENF) criterion. It involves extracting the embedded power line (utility) frequency from said recordings and matching it to a known database to verify the time the recording was made, and its authenticity. In this paper, a nonparametric, adaptive, and high resolution technique, known as the time-recursive iterative adaptive approach, is presented as a tool for the… CONTINUE READING
