Mechanisms¶
- Spoofing & Counter-Forensic Challenge
- The claim rests on the recording's electric network frequency trace — the tiny fluctuations of the mains hum, which drift in a way that can be matched against grid records to time-stamp a recording.
This sourceShows that a recording's ENF trace can be matched against reference-frequency records to test or identify its recording time.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Not recorded. The single citation of this work carries no recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
