Snowden-backed Haven app uses your smartphone’s sensors for monitoring


Haven for Android

Freedom of the Press Foundation where Edward Snowden is one of the directors and Guardian Project have jointly developed an open-source app called Haven for Android that uses a sensors on the phone to provide monitoring and protection of physical spaces. The developers say that the app has especially been developed for investigative journalists, human rights defenders, and people at risk of forced disappearance.

The app is for people who want to keep an eye out for intrusions into their home, office, hotel room or other private space. You need to install the app in a cheap Android phone to use it for monitoring and can access logs from other app or desktop.

The accelerometer on the phone detects phone’s motion and vibration, front or back camera is used to detect motion in the phone’s visible surroundings, microphone detects noises in the environment, ambient light sensor detects change in light and the phone can also detect device being unplugged or power loss.

The app only saves images and sound when triggered by motion or volume, and stores everything locally on the device. You can position the phone’s camera to capture visible motion, or set your phone somewhere discreet to just listen for noises.

You also get secure real-time encrypted alerts of intrusion events instantly and access the logs remotely or anytime later. These logs can be remotely accessed through a Tor Onion Service. It also supports SMS text notifications, if there is no internet connectivity. The app has several use cases. Since the app is still in beta, it might have some bugs.
