Detection · Display tampering
Detect display tampering in remote interviews.
Selective screen capture, overlays, extra monitors, and virtual displays let a candidate present a clean shared screen while prompts and answers stay visible somewhere the interviewer can't see. Capifiq surfaces display tampering and seals it as evidence.
The threat
A clean screen share, hiding the rest.
Screen sharing only shows what the candidate chooses to share. With a second monitor, a virtual display, selective capture, or an overlay, they can present a tidy, empty screen to the interviewer while the real workspace, notes, an AI overlay, a coding assistant, sits on a display that is never shared.
What the interviewer sees is curated. What matters is on the screen they don't.
Techniques in this category
- Extra or second monitors
- Virtual and phantom displays
- Selective window or region capture
- Screen overlays on the candidate's side
- Display-spoofing utilities
- …and new tricks as they appear
The blind spot
Why the shared screen looks clean.
Screen sharing transmits a chosen surface by design, so anything outside it is invisible to the interviewer.
You see what they share
Screen sharing transmits a surface the candidate selects. Anything outside it is invisible by design.
Extra and virtual displays
A second or virtual monitor holds the real workspace while a clean display is the one that gets shared.
A curated view
Selective capture and overlays present content that doesn't match what is actually on the candidate's screens.
What Capifiq surfaces
- Extra or virtual displays in use during the session
- A mismatch between the shared screen and the candidate's actual displays
- Overlays presenting content the share can't see
- Cryptographically hashed, sealed evidence for review
The coverage
Caught by the displays, not the share.
Capifiq surfaces when a candidate has extra or virtual displays, or when what is shared doesn't match what is actually on their screen, revealing content they can see but the share can't.
The finding is timestamped and sealed for the interviewer to review.
The full picture
On-device is only half of it.
Capifiq detects any unauthorized assistance running on the candidate's device. This is one of the common vectors, not a fixed list. And for help that never touches the device, the Question Engine builds questions it cannot usefully answer.
Hidden AI assistants
Desktop and web tools that feed answers on a hidden overlay.
Remote-control sessions
Another person viewing or driving the candidate's machine.
Virtual machines
A second environment concealing unauthorized tools.
Virtual cameras & deepfakes
A substituted or manipulated webcam feed.
Browser-based assistants
Extensions and web apps that generate answers.
Off-device cheating
Outpaced by the Question Engine: the second pillar.
Questions
Common questions.
Does having two monitors mean someone is cheating?
How is this different from a hidden AI overlay?
Can Capifiq see the display that isn't shared?
What about a new display-spoofing tool?
