About Simple Tracer

On the 31st of December 2019, the world as we knew it began to crumble. As we celebrated the beginning of a new decade, a deadly new virus was spreading in Wuhan, China. And it spread fast, one infected person could spread COVID-19 to thousands of people. As we built this project, we were still fighting the pandemic and the battle is very far from over. We've seen first hand, the effect a pandemic can leave.

One thing we've observed is the effectiveness of contact tracing as a utility to fight the pandemic. So we built a tool that allows for contact tracers to identify people who enter the same building. The idea behind it is that any administration could deploy it in under an hour. This means that if one person who entered a shop gets infected, the people who were at the shop get a message that serves a quarantine order and it is logged that they have entered quarantine.

Simple Tracer consists of five key components:

1. Flamingo, the app for residents to check in to buildings. Built with Flask as a PWA.

2. Hummingbird, a website that powers building registration and QR code generation. Built with Flask

3. Hornbill, a web app for contact tracers to identify contacts and issue quarantine orders. Built with Flask

4. Parrot, a python script for creating admin users for Hornbill.

Collectively, all of these can deployed with just a few clicks by following the guide below.

Deployment Instructions

🚩 Stage 1: Airtable

We use Airtable for a database. You can learn more about Airtable here. The free plan for Airtable is sufficient to demo this app, however to deploy this solution in production you will almost certainly need the Airtable Enterprise plan. You can learn more about it here.

The reason for using Airtable is that it can be built on top of extremely quickly and every day counts in a pandemic. This will allow you to build custom solutions.

1. To begin, we need to create a workspace. Here is a guide on how to do that.

2. Next you need to make a copy of the base template we have created. You can find it here. Click Copy Base in the top right corner.

3. So that your deployments will be able to interact with your Airtable base we will need to get an API key and the Base key. To do this you must:

   1. Go to this page.

   2. Find the API section and click generate

   3. Copy the provided key this is your API key.

   4. To get the Base key go to this page and click the base we created earlier.

   5. Use control f or command f to find 'The ID of this base is' on the page.

   6. The ID following that will be your Base Key

   7. Make sure to note down both keys.

🚩 Stage 2: Twilio

This can get a bit complicated, we'll let the people over at Twilio explain with this great guide. It will run you through the process of creating a Notify service in Twilio. You only need to follow the guide up to the Gather account information section.

Once you are done you should have the following information:

🚩 Stage 3: Hornbill

Now we want to deploy Hornbill, our admin tools system. This setup also uses Heroku and is similar to Eagle's.

1. Click this link.

2. Fill in your app name and a server location.

3. For the AIRTABLE_BASE enviromental variable, enter your Airtable Base Key.

4. For the AIRTABLE_KEY enviromental variable, enter your Airtable API Key.

5. For the KEY enviromental variable, we need to generate a key (unlike before we can't just use a random string of letters).

   1. To do this we will use Python, open your terminal and type python. Or use this site if you don't have Python installed.
   2. Next, type import os and click enter.
   3. Now, type import base64 and click enter.
   4. To end, type print(base64.urlsafe_b64encode(os.urandom(32)))
   5. Copy the result, if your result has b' at the start delete that as well as the ' at the end.

6. For the TWILIO_ACCOUNT_SID enviromental variable, enter your Twilio Account SID you made earlier.

7. For the TWILIO_AUTH_TOKEN enviromental variable, enter your Twilio Auth Token you made earlier.

8. For the TWILIO_NOTIFY_SERVICE_SID enviromental variable, enter your Twilio Service Instance SID you made earlier.

9. Click Deploy App.

10. Once the app is deployed, click View App. Welcome to Hornbill, but what is my password?

🚩 Stage 4: Parrot

Parrot is a simple command line tool that allows you to add admin users so you can login to Hornbill.

1. Write the following in your terminal:

mkdir parrot

cd parrot

git clone https://github.com/simple-tracer/parrot.git

python3 parrot.py new

2. This will start the process of creating a new user. Fill in the requested details, make sure the Secret key is the same as made in Step 5 of the Hornbill stage.

3. Now you have created a new user, you can login in on Hornbill.

4. To update a user's password replace new with update. To delete a user replace new with remove.

🚩 Stage 5: Flamingo

Next up we are deploying Flamingo, the tool everyday citizens use to check in and out of places. This setup also uses Heroku.

1. Click this link.

2. Fill in your app name and a server location.

3. For the AIRTABLE_BASE enviromental variable, enter your Airtable Base Key.

4. For the AIRTABLE_KEY enviromental variable, enter your Airtable API Key.

5. Click Deploy App.

6. Once the app is deployed, click View App.

🚩 Stage 6: Hummingbird

Lastly we are deploying Hummingbird, which powers place registration and QR code generation.. This setup also uses Heroku.

1. Click this link.

2. Fill in your app name and a server location.

3. For the AIRTABLE_BASE enviromental variable, enter your Airtable Base Key.

4. For the AIRTABLE_KEY enviromental variable, enter your Airtable API Key.

5. Click Deploy App.

6. Once the app is deployed, click View App.

🎉 Amazing! We've succesfully set up Simple Tracer!

Usage Instructions

Hornbill

Login

When first loading up the app, you will be asked to login.

Enter the details you generated with Parrort.

And you are in!

Issuing Quarantine Orders

Click this button to fetch contacts.

Enter the ID number, ensure this is the one used with Simple Tracer.

And here are the contacts, click on the boxes to expand and see more details. When you are ready click "Issue Quarantine Orders"

Clicking "Issue Quarantine Orders" will send them a text saying:

You have been in contact with a recent COVID-19 case. Please do not leave your residence, you are now required to enter 14 days of self isolation. If you are outside, return home immediately. Thank you.

And you've done it!

Parrot

Flamingo

To install Flamingo, users should go to your link and they will receive a prompt to install it as a PWA.

The first screen is this, it is a camera window which can be used to position the camera to see a QR code.

The user will then be asked for more details

The system will check if it has details for that account, if it doesn't it will ask for more. Otherwise this page will be skipped.

And success!! The person has been checked in.

To checkout, they just need to scan the QR code and enter their ID again.

Hummingbird

Coming soon.
