    @Override
    public void onSensorChanged(SensorEvent event) {
        // Process accelerometer data
    }
}

privacyIDEA (Python):

class TokenClass(object):
    def check_otp(self, otp, options=None):
        # Validate one-time password
        return self.check(otp, options)

Haven is primarily focused on personal device security using sensors, while privacyIDEA is a more comprehensive identity and access management system. The code snippets reflect their different purposes, with Haven processing sensor data and privacyIDEA handling token validation.

DuckDuckGo Android App

Pros of DuckDuckGo Android

  • Focuses on privacy-centric web browsing and search
  • Larger user base and more frequent updates
  • Comprehensive mobile app with additional privacy features

Cons of DuckDuckGo Android

  • Limited to web browsing and search functionality
  • Less customizable for specific security needs
  • Not designed for physical security or surveillance

Code Comparison

Haven:

public void startMonitoring() {
    mIsMonitoring = true;
    EventTrigger.getInstance(mContext).start();
}

DuckDuckGo Android:

fun onCreateBrowser(tabId: String, query: String?) {
    viewModelScope.launch {
        command.value = Command.NavigateToNewBrowser(tabId, query)
    }
}

Haven focuses on event triggering for security monitoring, while DuckDuckGo Android emphasizes browser creation and navigation. Haven uses Java, whereas DuckDuckGo Android is written in Kotlin, reflecting their different purposes and development approaches.

Both projects prioritize user privacy but in different contexts. Haven is tailored for personal security and surveillance, while DuckDuckGo Android aims to provide a privacy-focused web browsing experience. The code snippets highlight these distinctions, with Haven's code centered on monitoring and DuckDuckGo's on web browsing functionality.

About Haven

Haven is for people who need a way to protect their personal areas and possessions without compromising their privacy. It is an Android application that leverages on-device sensors to provide monitoring and protection of physical areas. Haven turns any Android phone into a motion, sound, vibration and light detector, watching for unexpected guests and unwanted intruders. We designed Haven for investigative journalists, human rights defenders and people at risk of forced disappearance to create a new kind of herd immunity. By combining the array of sensors found in any smartphone, with the world's most secure communications technologies, like Signal and Tor, Haven prevents the worst kind of people from silencing citizens without getting caught in the act.

View our full Haven App Overview presentation for more about the origins and goals of the project.

Announcement and Public Beta

We are announcing Haven today, as an open-source project, along with a public beta release of the app. We are looking for contributors who understand that physical security is as important as digital, and who have an understanding and compassion for the kind of threats faced by the users and communities we want to support. We also think it is cool, cutting-edge and making use of encrypted messaging and onion routing in whole new ways. We believe Haven points the way to a more sophisticated approach to securing communication within networks of things and home automation system.

Project Team

Haven was developed through a collaboration between Freedom of the Press Foundation and Guardian Project. Prototype funding was generously provided by FPF, and donations to support continuing work can be contributed through their site: https://freedom.press/donate-support-haven-open-source-project/

Safety through Sensors

Haven only records when triggered by sound and motion and stores everything locally on the device. You can position the device's camera to capture visible motion or place your phone somewhere discreet to listen for noises. Receive secure notifications of intrusion events instantly or access logs remotely later.

The following sensors are monitored for a measurable change, and then recorded to an event log on the device:

  • Accelerometer: phone's motion and vibration
  • Camera: motion in the phone's visible surroundings from front or back camera
  • Microphone: noises in the environment
  • Light: change in light from ambient light sensor
  • Power: detect device being unplugged or power loss

Building

The application can be built using Android Studio and Gradle. It relies on a number of third-party dependencies, all of which are free, open-source, and listed at the end of this document.

Install

You can currently get the Haven BETA release in one of three ways:

or add this repository manually in F-Droid's Settings->Repositories: https://guardianproject.github.io/haven-nightly/fdroid/repo/

You can, of course, build the app yourself, from source.

If you are an Android developer, you can learn more about how you can make use of F-Droid in your development workflow, for nightly builds, testing, reproducibility and more here: F-Droid Documentation

Why no iPhone Support?

While we hope to support a version of Haven that runs directly on iOS devices in the future, iPhone users can still benefit from Haven today. You can purchase an inexpensive Android phone for less than $100 and use it as your "Haven Device"; leaving it behind whilst you keep your iPhone on you. If you run Signal on your iPhone you can configure Haven on Android to send encrypted notifications, with photos and audio, directly to you. If you enable the "Tor Onion Service" feature in Haven (requires installation of "Orbot" app as well) you can remotely access all Haven log data from your iPhone using the Onion Browser app.

So, no, iPhone users we didn't forget about you and we hope you will pick up an inexpensive Android burner today!

Usage

Haven is meant to provide a smooth onboarding experience that walks users through configuring the sensors on their device to best detect intrusions into their environment. The current implementation has some of this implemented, but we are looking to improve this user experience dramatically.

Main view

The application's main view allows the user to select which sensors to use along with their corresponding levels of sensitivity. A security code is required to disable monitoring, which must be provided by the user. A phone number can be set, to which a message will be sent if any of the sensors are triggered.

Notifications

When one of the sensors is triggered (reaches the configured sensitivity threshold), notifications are sent through the following channels (if enabled):

  • SMS: a message is sent to the number specified when monitoring started
  • Signal: if configured, can send end-to-end encryption notifications via Signal

Note that it is not necessary to install the Signal app on the device that runs Haven. Doing so may invalidate the app's previous Signal registration and safety numbers. Haven uses normal APIs to communicate via Signal.

Notifications are sent through a service running in the background that is defined in class MonitorService.

Remote Access

All event logs and captured media can be remotely accessed through a Tor Onion Service. Haven must be configured as an Onion Service and requires the device to also have Orbot: Tor for Android installed and running.
