Overview
The recording used to be the fixed point
Verify identity on live camera networks, search recorded footage, and check whether a video, a voice or an online account is genuine.
An investigation has always leaned on recordings. A voice on a call, footage from a camera, a photograph sent between two phones. Whatever else was disputed, the recording itself was usually the fixed point everything else got measured against.
That is no longer safe to assume. A voice can be copied from a short sample, a face can be placed onto somebody else's body, and an account with years of apparent history behind it can be built in an afternoon. The damage runs in both directions: a fabricated recording can send an enquiry in the wrong direction for months, and a genuine one can be brushed aside by a suspect simply claiming a machine made it.
The checks below examine the material an investigation actually collects and return a graded finding with the reasoning behind it, showing what was noticed and where. That is what lets a line of enquiry be justified at the time and the work be reviewed later by a supervisor, an expert instructed by the defence, or a court.
