The hardest part of facial attendance isn’t detecting a face.

It’s proving the face is real and physically present.

I built a browser-based liveness system (no ML API, no server verification).

[Tomi Da Web Dev @TomiDaWebDev]

Why this works:
• Photos fail early (no motion)
• Videos can’t predict random step 4
• Requires real-time response, not replay
Built with face-api.js + pure JS geometry.
Detecting a face is easy. Proving presence isn’t.

Yaw ratio: yaw = leftEye_to_nose / (leftEye_to_nose + nose_to_rightEye)
MAR (mouth): MAR = vertical_mouth / horizontal_mouth
EAR (eyes): Used to detect blink via sudden drop across frames

[Tomi Da Web Dev @TomiDaWebDev]

4-step challenge flow:

1. Look straight
2. Turn left
3. Turn right
4. Random challenge: • Open mouth OR
• Blink eyes

Each step must be held across multiple frames.

I am building a university attendance system that uses your face as your ID.
No paper. No proxy sign ins. Here's how 🧵

[Tomi Da Web Dev @TomiDaWebDev]

The liveness check is the key part.
Look straight → turn left → turn right → open mouth.
A photo held up to the camera fails all 4. On purpose.

@dev_olayinka Nah my battery said till whenever I'm able to recharge

Still shipping. Still learning.

Every Nigerian university student knows this scene.
The lecturer passes around an attendance sheet.
You sign your name.
Your friend signs for you when you're late or absent.
Everyone has 100% attendance. Barely anyone showed up.

4. All four. At the same time. No shortcuts.

It's a full-stack web app, PHP, MySQL, Tailwind CSS, vanilla JS.
It runs in the browser. No app store. No install friction.

This is my answer to a problem I've watched go unsolved for years.

3. To mark yourself present, you must:
→ Be physically holding the phone (liveness detection)
→ Be at the correct location (GPS verified)
→ Know the session code (only shared live in class)
→ Match the face you enrolled with from day one

2. That's proxy attendance. It's been the norm for decades.
It's unfair to students who actually come. And it makes the record completely meaningless.

So I built a system that makes it physically impossible.

PC died but I still had to push to GitHub regardless… then I remembered I was on Android 🥱

@dev_olayinka Amazon did the same too.
