This app is a smart picture privacy mediator for in crowded spaces. It allows the user to individually specify for each picture if he/she agrees on its usage.
Therefore, the app automatically generates low-res thumbnails of shot photographs in background and asks potentially pictured individuals for their consent (they also need this app).
The system works without any central server or tracking of users' positions. Phones detect their vicinity via WiFi Direct and exchange messages via google cloud messaging. No GPS, no login nor user account (Google or other) required.
This app has been supported by a netidee grant from the Internet Foundation Austria (IPA).
Hint: to see how this app works, you will need multiple devices with this app installed. Then, take a picture using the standard photo app and wait a few seconds. Please visit our web site for detailed information about this project, incl the source code.
