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, interviewing methodology deters what no software can see.
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
Deterred with interviewing methodology — 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?
Get started
See the screen they didn't share.
Run Capifiq alongside the Zoom, Teams, or Meet calls you already do, and see what it surfaces.
