Favent
product
After an event, each guest finds every photo they appear in by showing the app their face; the face is measured on their own phone or laptop and never uploaded.

What it does
The organiser points Favent at the event's photos and hands out a six-character token. The server finds every face and packs them into a small index.
A guest gives consent, shows the camera three frames, and their phone or browser searches that index itself. The face measurement stays there; the photos it finds are then fetched to show them.
A stranger can try it with no account: borrow a face from 140 photo-booth portraits the Rijksmuseum released into the public domain.
Measured
- 36 489faces in a 20 MB index of 52 GB of photos
- 3-4ms to search them with the Swift matcher, on a Mac
Where it stands
Runs on a laptop, in the browser and as an iOS app in the simulator; nothing is hosted or in a store, and its face models are licensed for non-commercial research only.
