Project Overview

Help us stop COVID-19.

COVID Safe Paths is a mobile app for digital contract tracing (DCT) sponsored by Path Check a nonprofit and developed by a growing global community of engineers, designers, and contributors. Safe Paths is based on research originally conducted at the MIT Media Lab.

Privacy Preserving

What’s truly special about Safe Paths is our strong commitment to preserving the privacy of individual users. We're building an application that can help contain outbreaks of COVID-19 without forcing users to sacrifice their personal privacy. For example, if a user chooses to use Safe Paths to maintain a record of their locations use a time stamped GPS log, which stores 14 days of data in 5 minute increments. The location log is stored on the user's phone. The logged data only leaves the device if the user chooses to send the information to an authorized public health authority (PHA) as part of the contact tracing process.

Multiple Capabilities

Safe Paths is designed to support a range of DCT and public health use cases. Currently the main build uses GPS for location tracking. Our roadmap includes adding support for other location and proximity technologies, symptom tracking, and communication with PHAs.

Multiple Implementation Strategies

The Safe Paths app is being developed to support a variety of build 'flavors' of the application around core health and tracing functionality. Reach out to our team to discuss creating a flavor for your use-case.

Path Check Release of COVID Safe Paths

Safe Paths is available as an app published by Path Check in the Apple App Store and the Google Play App Store. Any authorized pubic health authority can use Safe Paths.

Custom Builds

We welcome public health authorities and other organizations implementing digital contact tracing strategies to create custom builds for their specific needs, incorporate Safe Paths features into their applications, or create downstream projects that stay linked to the Safe Paths project. If intending to fork the repository and develop off of it, be aware that this comes "at your own risk" for continued maintenance.

End-to-End System

Safe Paths is designed to work with Safe Places, a tool for contact tracing teams to work with location data in the course of contact tracing interviews and to publish points of concern. Without having to sharing their own location history, a Safe Paths user can download the points of concern from their PHA to identify if they have had risk of an exposure.

Broad Non-Developer Community

One of the important aspects of the Safe Paths open source project is that it's supported by a large community of volunteers in addition to the open source developer community. Spanning as diverse domains as product management, user research, cryptography, security, compliance, design, and videography more than 1,400 Path Check volunteers are working together to support Safe Paths and help drive adoption around the world.

Development Overview

Safe Paths is built on React Native v0.61.5

Contributing

Read the contribution guidelines.

If you're looking for a first ticket - please check out the backlog for a bug or first story JIRA project.

Architecture

View the architecture diagram for a basic overview on the sequencing of generalized events and services that are used by Safe Paths.

Developer Setup

First, run the appropriate setup script for your system. This will install relevant packages, walk through Android Studio configuration, etc.

Note: You will still need to configure an Android Virtual Device (AVD) after running the script.

Linux/MacOS

dev_setup.sh

Windows

dev_setup.bat

Environment

Populate the following .env files. View an example file at example.env

.env.dev
.env.staging
.env.release

You can configure AUTHORITIES_YAML_ROUTE against https://raw.githubusercontent.com/Path-Check/trusted-authorities/master/staging/authorities.1.0.1.yaml.

ZENDESK_URL can be omitted in development, and the Report Issue page will throw an error when submitting.

Running

Note: In some cases, these procedures can lead to the error Failed to load bundle - Could not connect to development server. In these cases, kill all other react-native processes and try it again.

Android (Windows, Linux, macOS)

yarn run-android ## for the location enabled app

Device storage can be cleared by long-pressing on the app icon in the simulator, clicking "App info", then "Storage", and lastly, "Clear Storage".

iOS (macOS only)

First, install the pod files:

yarn install:pod ## only needs to be ran once

Then, run the application:

yarn run-ios ## for the location enabled app

Device storage can be cleared by clicking "Hardware" on the system toolbar, and then "Erase all content and settings".

Privacy settings can be reset by going to Settings > General > Reset > Reset Location & Privacy

Release Builds

Generating a release build is an optional step in the development process.

• Android instructions

Debugging

react-native-debugger is recommended. This tool will provide visibility of the JSX hierarchy, breakpoint usage, monitoring of network calls, and other common debugging tasks.

Tooling

TypeScript

This project is using typescript.

Run the complier with:

yarn tsc

Not every file needs to be written in TypeScript, but we are preferring to use TypeScript in general.

Note that for React-Native projects, TypeScript complication is handled by the metro-bundler build process and there is no need to emit js code into a bundle as one would do in a web context, hence the inclusion of the --noEmit flag.

Prettier

This project is using prettier.

We have a local prettierrc file, please make sure your development environment is set to use the project's prettierrc.

Husky

This project is using husky to automate running validation and tests locally on a pre-push git hook.

If you ever need to push code without running these scripts, you can pass the --no-verify flag on git push.

ESLint

This project is using eslint.

We have linting checks on CI, please make sure to include the checks locally in your IDE.

Testing

Tests are ran automatically through Github actions - PRs are not able to be merged if there are tests that are failing.

Static Testing

To run the static analysis tools:

yarn validate

Unit Test

To run the unit tests:

yarn test --watch

Snapshot testing is used as a quick way to verify that the UI has not changed. To update the snapshots:

yarn update-snapshots

e2e Test

Note: Right now, there is only e2e test support for iOS.

e2e tests are written using detox. Screenshots of each test run are saved to e2e/artifacts for review.

To run the e2e tests:

yarn detox-setup ## only needs to be run once
yarn build:e2e:ios ## needs to be run after any code change
yarn test:e2e:iphone{11, -se, 8}

Manual Device Testing

Mobile devices come in many different shapes and sizes - it is important to test your code on a variety of simulators to ensure it looks correct on all device types.

Before pushing up code, it is recommended to manually test your code on the following devices:

• Nexus 4 (smaller screen)
• iPhone 8 (smaller screen)
• Pixel 3 XL (larger screen)
• iPhone 11 (screen w/ notch)

safeplaces-dct-app's Issues

Put notification if location is not getting logged

The location might not be getting logged due to the location turned off through settings or some other reason. We need a rigorous way of testing it.

FEATURE: Restore the WebView

Restore the webview in the LocationTracking.js and have it point to https://privatekit.mit.edu/mobileportal

Combine and curate location data

Have the location data store under single object, not as independent pieces.

Basic operation logic:

locs = []
if ("loc_data" exists)
   temp_locs = load("loc_data")

   # Curate
   for (i=0; i < len(temp_locs); i++)
      if (temp_locs[i] < 28 days old)
         locs += temp_locs[i]

...

# After every snapshot
save(locs)

Play Store says App incompatible with all your devices[One Plus 5T, Android 8.1.0]

Update branding

Once the name is finalized, update the repo name, app strings, and any documentation that references "mobileapp"

Prettier throws warnings for incorrect formatting

Import Module: Load waypoints and path points from Google's Take out file

Google has several semantic ways to log lat, long. The current implementation only imports placeVisit.locations.

BUG: App beeps regularly

When installed on a real phone, the app beeps every time it captures a GPS coordinate. Very irritating and a sure way to get uninstalled!

iPhone 11 - 13.3 doesn't allow

Feature - Localize the app to support various languages

What is the feature -

Setup Internationalization framework to make the app multilingual.

What this feature can do -

1. detect the user language
2. load the translations
3. optionally cache the translations
4. etc

Why is it needed -

When the app will reach millions of people around the globe, they will prefer to have it in their local language.

Improve Google Location Data import experience

The Import functionality is great, but still tricky to use. It might take a few iterations to get it to what we want, but here are some thoughts:

Break the Import into three stages, kinda like an old-school Wizard.

1. "Intro" page.
   Explain what this does and give instructions to log in and start the process w/Google.
   Q: Can we explore the DOM on the webview? It would be cool to watch for an indicator that the request for a takeout has happened, then move to the "Waiting" step described below.
2. "Waiting on Google takeout" page
   If the user returns to Import page, show a message that we are still waiting on the takeout file.
   Include a "Start over" button to go back to Step 1 in case something fails.
3. "Import Complete"
   After an import completes, the results of the import should be remembered and displayed. E.g.
   "28 day of data imported from Mar 1 - Mar 28".
   Also have an "Import again" button that goes back to step 1.

During Step 2 the user should be be able to leave the app or go back to the main page. We should have a background task look for the takeout file when one is pending, so you don't have to go back to Import. The app should show a notification when the takeout file is found and process completes.

Discussion is welcome. I expect the implementer will find challenges and opportunities to improve this sequence. For instance, there might be a step 2.5 that helps with the download of the Takeout file.

Import Locations from Google on iOS: Browser opens the Zip file in the Webview.

On Android, the app saves a file in the Downloads folder.

On iOS, the WebView shows the zipped binary file in the app itself.

We need to figure out a way to either download it to a file and then open with the SearchAndImport function or keep it in memory (500MB in memory?) and pass it to the SearchAndImport function.

Refine Share

The basic Share functionality works, but it could use some refinement. Specfically two things:

• Improve the filename. Currently it is ".null". Change it to be "PrivateKit_.json"
• Add a message body. Try:
  Here is my location log from Private Kit.
• If titles are supported, make it: "Shared PrivateKit_.json"

No indicator during Location service failures

There are several reasons that location information might not be working properly:

• GPS has been turned off
• User disabled the permission under settings
• Under iOS, app was shutdown in the background
• Probably others

We need to validate access to GPS and notify/prompt the user when this happens.

FEATURE: Add Face/Pin/whatever unlock on open

Use the operating system's current unlocking mechanism to open the app and show the data. The idea is to minimize snooping without the permission of the phone's owner. A good example of good implementation is the unlocking feature of Signal's Messaging app.

Implementations have to work on iOS and Android.

Apple Rejection: Do we need Motion Tracking?

We noticed that your app requests the user’s consent to access their motion but does not clarify the use of the motion in the applicable purpose string.

Next Steps

Please revise the relevant purpose string in your app’s Info.plist file to specify why the app is requesting access to the user's motion and location. You can modify your app's Info.plist file using the property list editor in Xcode.

To help users understand why your app is requesting access to their personal data, all permission request alerts in your app should specify how your app will use the requested feature.

FEATURE: Verify application freshness

Add a mechanism to remind the user to update if they have turned off auto-updates on their phone.

The first version can be a simple notification when the app is outdated.

Add webview

The "Info: N/A" needs to become a webview

The location settings alert box is not consistent

Right now for the phone versions which don't show 3 options for location (while using, always, never) but instead 2 options (always/yes, never), the location prompts up for them unnecessarily. We will have to dig deep into the response numbers by the geolocation api.

BUG: iOS version not building from 'develop'

Currently you cannot build the iOS version of the app. The error reference the 'tripleblind' app, so it is likely that it has to do with renaming packages.

Can test against the first release off of the 'master' branch, which I believe did function.

Clicking on privatekit link during welcome screen throws error

My guess is it just needs to load one library responsible for this. Didn't look into detail, this got popped up while fixing some other issue.

Bring up the location data collapse PR changes back

FEATURE: Import of location data from Apple

Looking for suggestions about pulling in info from Apple like Google Takeout. If this requires Apple's assistance, we have some connections.

Show a loader while the WebView of Import is Loading

Currently there comes a white screen and it stays for 7-8 seconds

Average users will go back in the meantime

Need to test on iPhone

So far this hasn't been run on iOS at all. Especially interested in the location service and if it runs in the background properly.

Back button will go to the Welcome screen

If you log in, Start Recording, then hit the Back Button it should exit the app -- not got back to the Welcome screen.

Pressing back from homescreen should exit the App

Right now the app goes back to the first Welcome screen if we press back.

VERIFY: Backfill Stationary point captures if needed

The BackgroundGeolocation library has the ability to only report changes in location when the user moves. This saves power in some cases, e.g. if the phone is sitting on a charger and not moving, the accelerometer shows it is stationary. The library saves power by returning a Stationary point.

Verify the behavior around this. I suspect it only generates a callback once, then stops calling until the phone moves again. If this happens, upon the move we should backfill so that we have the same point reported at 5 minute intervals until that next point report.

Example:

@3:01 - I set my phone down on the desk
@3:02 - The BackgroundGeolocation callback triggers and we save a coordinate
@3:40 - I move my phone
@3:40 - The BackgroundGeolocation callback triggers and we save a coordinate

If the above does occur (which we need to verify), we should save the same reported coordinate from 3:02 at 3:07, 3:12, 3:17, 3:22, 3:27, 3:32, 3:37 and then save the new 3:40 coordinate.

Battery Usage is high

Not unexpected but I think we can do better.

iOS doesn't record location even if the application is running in foreground.

The first two points were logged, nothing afterwards.
Devices

• iPhone11 - 13.3

EDIT -
Seems like it is only happening when it is stationary. If I use bike riding simulator, it stops.

Stop recording location does not remove the notification bar

When the location logging is not on, even then the notification bar keeps showing the location is getting recorded.

Debugger warnings when loading app (require cycles)

I am getting a lot of these warnings when opening the app.
Xcode 10.2 and iOS 13.3.2 simulator (iPhone 8).

I'm not an iOS developer, but I can try to fix it if needed.

iOS build fails with yarn install

In my setup, I required to perform pod install as well in order to get npx react-native run-ios running successfully.

Xcode 11.3.1

** BUILD FAILED **

BUG: Application installs under the name "Tripleblind"

The icon needs to get the name of the app "Safe Paths". (At least that is the working name for now)

iOS not building on develop (45fc937419069a94dab3d4dd11deab4f33b080a0)

I am getting this error on the iOS build for develop 45fc937

It gets stuck on a white screen and the app fails to load. I tested release v0.5 and it worked.

Device iPhone 8 - iOS 13.3.1

Improve the saved point description

Currently the Export page shows some basic info about the saved data. It displays:
Points to be shared: 6134

We should expand this into something more friendly. Describe number of points, oldest date, and how recently it was updated.

Example:

Log has 22 days, 345 points, last updated 4 minutes ago.

Once that is possible, we can see it if will fit on the main screen, updated each time a new point is saved.

NOTE: Be aware that the stored datetime info is in UTC. Should be able to just subtract the first point's time from the current unixtimeUTC, then do division to figure out the number of days saved.

Check and prompt if the location is disabled

This should be helpful -

Google Import should expand logged points for duration

During the import of Google data the time is imported a single time/coordinate. However, the Google data has durations, so we should use that to expand points. This will be useful later in the intersections.

Basically, the Google data contains something like:

[ 
 {"placeVisit": {
      "location" : {
        "latitudeE7" : 423936728,
        "longitudeE7" : -710802770,
      },
      "duration" : {
        "startTimestampMs" : "1583085476383",
        "endTimestampMs" : "1583086992817"
      },
   }
}
...
]

The start time is: Sunday, March 1, 2020 5:57:56.383 PM
and the end time is: Sunday, March 1, 2020 6:23:12.817 PM

That is 26 minutes of the user at the same point, so import it in 5 minute intervals so it looks like:
[
{ startTimestampMs, latitudeE7, longitudeE7 },
{ startTimestampMs + 5 minutes, latitudeE7, longitudeE7 },
{ startTimestampMs + 10 minutes, latitudeE7, longitudeE7 },
{ startTimestampMs + 15 minutes, latitudeE7, longitudeE7 },
{ startTimestampMs + 20 minutes, latitudeE7, longitudeE7 },
{ startTimestampMs + 25 minutes, latitudeE7, longitudeE7 },
]

Don't stress too much about overlap between places, we can work with having time segments that are narrower than 5 minutes. But we will likely have issues intersecting in encrypted space with a timespan between points that is > 5 minutes.

Additionally, the transit points aren't being imported. It would be nice to import waypoint data.

Address security alert: minimest

The main repo has a warning:
https://github.com/tripleblindmarket/private-kit/network/alerts

Feature request: self-reporting features

From conversations with @ericlavigne on the MIT TR article:

1. Due to the delay in testing, it might be better to implement self-reporting of previously visited locations (via pinpoints, not long/lat). The users would be able to populate at least some of the data not collected because they didn't install the app at the time, the app crashed on some days, etc.

2. We could implement the possibility of checking for negative results/ absence of symptoms, when distributing warnings to contacts. Might be useful to trace secondary contacts and refine predictions.

View overflows on small screen

The top part just goes away if the screen size is small.

FEATURE: Import Google Location data

It would be valuable to have a button that will reach out one time to import the user's Location history from Gogole. This would give them an instant 28 day cache moments after installing the application.

TESTING: Verify logging resumes on reboot

Like the title says! Please note in comments if you see it work under iPhone and under Android.

Security scan: OWASP Mobile Top 10

We should scan the v1 release candidate to make sure we haven't introduced any obvious security problems. OWASP Mobile Top 10 is a good start.

FEATURE: Export trails

Look into using a QR code to either hold the location trail or hold the key to decrypt a version uploaded to a public drop URL (any anonymous drop).

Redirect to settings in iOS for always on location settings

In iOS, we haven't found a way so far to have always on location settings enabled through pop-up which comes on the app. So for now, we will redirect the user to location settings where they can click on always on.

Add info on what trails exist

Display very simple information on the status of trails. E.g. at the bottom of the main app:

    Trails:  12 days, last updated 2 minutes ago

PLAY STORE: Entry not available in India

Android: App Crash

App Crashes when Denied permission for "location" access permission when started app for the first time.

Audit licenses

We need to audit the licenses of all plugins in. Note any that require a visible attribution. If we have any, we will need to create an About page that shows that.
