Giving back the power of informed decision during pandemic or other crisis

Ensure social, economic and health trust by implementing a “feel safe” data system that will enable people to make a decision before visiting public or commercial spaces or selecting a tourist destination

During this hackathon, we worked to create a solution that will empower social and health trust through the development of an open-source modular sensor system & a secure data layer that enable people to make a decision before visiting public spaces/ tourist destinations.

Inspiration / What it solves

What inspired us the most was the possibility to use A2W to strengthen the power of decision, the right to liberty and recover the perception of community safety. We want to give these “powers” back to people and by people we mean decision-makers, business people, managers and above all to all citizens

We live in a tourist region that is deeply affected by this pandemic at economic and social level, scenario shared by countries with a high percentage of their economy being driven by tourism. However, we wanted to develop a solution that helps tourist regions to recover the trust of both locals and visitors, while at the same time having a broader scope applicable to all societal challenges.

Our project solves many problems at different levels:

1. Contributes to a faster recovery of the economy;
2. Contributes to a happier, healthier and safer lifestyle for citizens and visitors;
3. Empowers individual citizens by giving them back the freedom and the power to make “safe” choices;
4. Provides governments with reliable data to act immediately in critical areas;
5. Enables constant monitoring of trust and safety;
6. Creates a trust relationship between governments, organizations, businesses and people.

The A2W System main advantages

1. It’s scalable and evolutive to monitor other pandemics, local epidemic diseases or even global and societal challenges, namely climate changes;
2. It’s localized into multiple languages;
3. It has open source features to enable developers worldwide to implement and contribute to its development;
4. Enables circular economy;
5. Promotes the digital economy.
6. Promotes territorial resilience;
7. Protect people, communities, economic activities and businesses;
8. Encourage responsible practices and choices;
9. It stimulates the innovation ecosystem at different scales and the co-promotion.

Impact to the Crisis

The A2W’s versatility, accessibility and scalability can have an impact in the following areas.

Economy: -Applicable to both small and large businesses, regardless of number of staff and customer base. -It can provide both customers and staff with enough data and educative content to reassure any concerns. -This reassurance is bound to increase sales, productivity and overall revenue.

Government:

• The anonymously collected data can help officials to manage public spaces, contagion trends, and redistribution of resources
• Some applicable measures include the closure or disinfection of specific public spaces (instead of widespread lockdowns), the indiscriminate notification of citizens who might have been in a contagion zone, or the deployment of funds or other resources to cities or regions displaying early signs of mass infections.
• Local and central governments can use the data to engage in targeted educational or informational campaigns.

Society & Cohesion:

• Return the autonomy and the rights that citizens lost to the emergency measures and lockdowns (for example, freedom of movement).
• Contribute to the combat of discrimination based on gender, race, class or physical attributes. This results from the anonymity provided by temperature readings, A2W’s widespread reach through smartphones or phones (via government), and audio-visual cues in locale.
• Actively curb economic hardship via job maintenance.
• Preserve the social pillar of democratic nations by assuring that schools, courts of justice, parliaments, or hospitals (to name a few) will be able to work with an extra layer of protection.
• Protect society’s most vulnerable populations by monitoring interactions in soup kitchens, food banks, elderly homes, orphanages, or refugee camps (among many others).

What it does

The A2W System empowers social and health trust through an open-source modular sensor system & a secure data layer that enables people to make a decision before visiting public spaces/ tourist destinations. Our system was conceived with due regard for all the existing regulations concerning hardware certification, data protection compliance and data encryption.

In essence, our A2W Project has two main goals in a complementary and co-responsible process:

Governmental level The A2W System allows the data collected anonymously to be used by Governmental Entities to monitor their countries and enables them to make timely decisions by interacting with specific places, cities, regions and feed an app based on maps solutions to inform people about the “safest places” to go and enable them to make a decision.

Public & Commercial level Implementation of AW2 Pods in public accesses will remind users that they have to have their masks on, perform hand hygiene before entering the place, put shoe covers if required, etc. Moreover, it will use its proximity sensors to control the number of people that are getting in and out of the place. By doing so, at the same time, it uses the infrared sensor to measure the temperature of the person using the gel dispenser. This measurement is anonymous, since the station only registers a temperature and sends it to a cloud on the internet via an encrypted connection.

How we built it

This project has been built with the skills and knowhow of a multidisciplinary team, a lot of motivation to help others, and resourcing to different languages, hardware, libraries and frameworks available:

A2W EuropeChain Backend development:

The AW2 EuropeChain back-office for admin purposes should be built to manage and control all the B2B stakeholders and the subscription system. Connectivity to secure public clouds/blockchain should be managed here as well.

Data sent from pod to EuropeChain:

• Geolocation.
• PAX Counter.
• Air Humidity.
• Number of Thermal Cases.
• Timestamp.

Europechain can handle 10.000 requests per second. We will balance the amount and periodicity of the transfers to maintain system stability.

Programming Stack for intermediary database:

• Python and Django.

Database and data encryption:

Data is anonymous but authenticated and validated, with the blockchain and the cryptographic proof that the information is stamped at a specific time and place.

Europechain - https://europechain.io / Blockchain

API

Secure connection from the pods to EuropeChain, from europechain to apps and national healthcare database.

National Healthcare and Contact tracing ( Apple / Google ) connectivity:

This connection will be done through a secure channel via EuropeChain and the national healthcare database.

Considering National Services Mobile App,if connected to Google and Apple contact tracing database could warn people that were in the proximity of the pods that someone infected was at the same place at same time.

Mobile App Development

The Mobile app should inform and empower citizens to make educated decisions about population density and high temperature cases in a map and decide how and where to go.

• Flutter.
• Maps Solution:
• ArcGIS ( open source ).
• Wizzimaps.

Hardware Prototype:

Hardware connects to the cloud via our A2W OS, this system is built on top of RaspianOS and with preset configurations for Arduino and the necessary sensors.

This code should be open source and with the ability to connect to Europechain.

A2W POD (see image in slider named A2W POD)

A2W Pod Diagram (see image in slider named A2W Pod Diagram)

The measurement pod is a compact device based on Raspberry Pi hardware. It collects data from sensors, such as temperature scanners, and uploads the measurement result to the public blockchain (Europechain). The pods are either using the local facility's WiFi connection, or LTE mobile network for uploading the data.

Each pod generates a private key securely, and the corresponding public key is certified on the blockchain, associating it with device location.

The device is constantly collecting the measurements, aggregating and sending transactions to the blockchain every few minutes, supplying the following data:

• device identifier
• observation interval
• estimated number of people by counting unique BlueTooth and WiFi devices
• number of temperature measurements
• number of people in each temperature range, such as [36.5-37], [37-37.5], [37.5-38], and so on, degrees Celsius.
• room temperature, humidity, other values as needed.

The measurement data is collected from the blockchain in real time and processed for displaying and real-time monitoring.

Challenges we ran into

The main challenge came from the quality of data gathered by the infrared temperature measuring station, as well as the challenges by facial recognition and people's privacy, so, considering this, all the data gathered is 100% anonymous. At all moments we were always aware of the issues related with data protection and all the legislation in force and implemented the system accordingly, keeping all measurements anonymous and implementing a secure data encryption process.

Accomplishments that we're proud of

We are proud of having been able to team up with a project that was already being developed by experts in the field of physics to add up social, economical and political aspects that will make the solution really global, scalable and evolutive due to its open-source code.

What we learned

We’ve learned that the impossible is possible when we put together a team of different skilled people, from different backgrounds and with different concerns around the same problem to find together a solution.

What's next for Algarve2W

We want to make this project global and have people from all over the world implementing and creating add ons that will grow this project to a worldwide level. We want to feel we are part of a solution that brings back normality to every citizen’s life, we want to see cities being live again, people feeling safe and happy and businesses growing. We are sure that this project is 100% marketable and that can be implemented in the short run.

There are many possibilities to implement this project further: Shops that have the device installed could incentivize the user/citizen to leave their contact details resulting in more services like: real-time downtime notification, discount on products, notification on protective equipment Municipalities can offer Social Coins to citizens that comply with policy not to visit crowded areas
