THREAT 01 / VIDEO
Deepfake video
Face-swap and overlay tools can place a convincing face over someone else, live, during the call.
Forensic AI Hiring Playbook
Deepfake video and real-time AI assistants now let a candidate fake a remote interview. These forensic checks prove the person you hire is a real expert doing their own work.
The 2026 problem
Between deepfakes and AI assistants answering in real time, the traditional interview cannot tell a real expert from an imposter.
THREAT 01 / VIDEO
Face-swap and overlay tools can place a convincing face over someone else, live, during the call.
THREAT 02 / AUDIO
A hidden dashboard feeds the candidate polished answers the moment you ask a question.
THREAT 03 / ACCESS
If an imposter clears your interview, you are trusting your code and your data to someone who cannot do the work.
The forensic tests
Two layers: confirm the face on screen is live, then confirm the answers are theirs.
Run it on every candidate as a standard, neutral part of secure hiring.
Slowly turn your head 90 degrees to the left, then to the right.
Watch for Distortion around the ears or a blurry jawline.
Slowly wave one hand across in front of your face.
Watch for Overlays glitch where a hand crosses the face.
Lean slightly toward the camera, then back again.
Watch for The background warps during the movement.
Count to five out loud while showing the numbers on your fingers.
Watch for Audio and finger timing drift out of sync.
Once identity is confirmed, test whether the thinking is theirs.
Real people do not answer on a fixed rhythm. An AI assistant takes the same beat to surface an answer whether you asked their name or how to scale a database.
The tell Identical pauses before every answer.
Ask them to explain a technical concept with a local analogy, like traffic on the 401. A real expert laughs and pivots.
The tell An imposter freezes or gives a generic answer that ignores the metaphor.

FAQ
Yes. A short, neutral identity check is a reasonable part of secure hiring. Under Ontario's AI hiring disclosure rules you must tell candidates if you use AI to screen them, so keep it simple: explain that the check is a standard verification step and that final decisions stay human-led.
No. The video identity check takes about 60 seconds, and a clear fail gives you a documented reason to close a file fast, which actually helps you stay inside Bill 190's 45-day decision window.
Detection tools help, but evasion tactics evolve faster than the tools chasing them, which is why detectors keep falling behind. These physical and contextual checks are cheap, fast, hard to fake live, and they keep a human in the loop where the final call belongs.
Not always. Sometimes a pro passes the interview and a junior shows up for the work, so the playbook includes post-hire steps: hardware and biometric verification, a first-day re-check, and language-pattern checks.
