Anti-Forensics and Countermeasures of Electrical Network Frequency Analysis

The electrical network frequency (ENF) signal is a time stamp that has been used by an emerging class of approaches for determining the creation time of digital audio and video recordings. However, in adversarial environments, anti-forensic operations may be conducted to manipulate ENF-based time st...
