What is DAVID19?
DAVID19 is a platform that works as a digital wallet aggregator. The app is part of an initiative led by the global alliance for the development of the blockchain ecosystem in Latin America and the Caribbean (LACChain). DAVID19 seeks to collect key information provided by each citizen in the fight against COVID19, privately and anonymously, with the aim of making the virus a visible enemy through the use of risk maps. The informational purpose of the platform in its deployment phase is similar to that of a survey: the more people who answer questions about symptoms or confinement, the smaller the margin of error and the more reliable the information. The goal is to have enough information density in each sector, city, state, country or region to have a more accurate picture of how the virus is progressing. However, the information provided should never be taken as the basis for health or other decisions at the personal or government level, until it has been officially verified by the competent authorities in each country.
What is LACChain?
LACChain is a regional program of the IDB Innovation Lab (IDB Lab) that was born with the purpose of accompanying and accelerating the development of the blockchain ecosystem in Latin America and the Caribbean, seeking to maximize the social impact and financial potential that the technology has to offer. In this program, the IDB Lab leads a global alliance with several of the leaders in blockchain technology at the international level.
How does DAVID19 work?
DAVID19 allows any citizen to download a free digital wallet to provide information anonymously regarding COVID19, such as whether or not they are isolated, or whether or not they have symptoms. The personal information remains in the person’s wallet, on their mobile phone, and only some part of the information is publicly displayed on maps and graphs so that it can be acted upon as the virus evolves.
What is a digital wallet?
Digital wallets are mobile applications that use sovereign digital identity protocols and standards, a new concept of digital identity, which allows users to control all their interaction on the Internet, own their data and protect their privacy. In the near future, digital wallets will allow for the storage of identity documents, digital property titles, digital diplomas, electronic money, and any other existing or future digital asset. At LACChain we are part of the growing belief that the future of identity lies in the use of digital wallets and digital sovereignty, and that the most secure and private way to share information is through decentralized registration.
What personal information is shared publicly?
The only personal data that is released from your digital wallet is your age, your gender (optional) and your location (which we make anonymous by reducing the accuracy to an area of one square kilometer near your position). This pseudonymous data does not let us see who provided it, and your real identity is known only to you. There is no database from the wallet provider or from the DAVID19 platform that can track any additional personal data from your wallet, such as your name, ID, or precise location.
How can DAVID19 help me?
DAVID19 allows you to access the world of self-sovereign identity (SSI) where, through a digital wallet (which is a mobile application), you can control all your information and interaction on the Internet in a safe and secure way, guaranteeing your privacy. In the first phase you will be asked to provide some information about your status in relation to COVID-19, to help us make the virus visible.
Who developed DAVID19?
DAVID19 is an initiative led by LACChain, a program of the Innovation Lab of the Inter-American Development Bank (IDB Lab). It was created and coordinated by LACChain with the support from everis, IOVlabs, World Data and Grupo Sabra as technology partners, and LLYC as the social communications partner.
When was the partnership for the development of DAVID19 formed?
The partners started working in March with the goal of protecting people’s privacy, unlike other similar applications. The alliance brings together different organizations and invites others to join in its open project model.
Why was DAVID19 created?
de identidad digital soberana. DAVID19 was created to confront our Goliath, represented by COVID-19. The growing health crisis in Latin America and the Caribbean, and even worldwide, requires a solution that is able to collect information and location of each person, while protecting their privacy and anonymity. DAVID19 is that solution, using blockchain technology and sovereign digital identity standards and protocols.
What is blockchain technology?
Blockchain is a technology tool that builds decentralized and immutable records of information. Each device, such as computers, connected to a blockchain network, is synchronized with all others and keeps a synchronized copy of the entire record. The information is recorded in the form of transactions that are grouped into blocks, thus the name blockchain.
What blockchain network is used?
The blockchain network used was developed by the LACChain alliance. This network is the first public-permissioned blockchain network offered in Latin America and the Caribbean at a regional level. The network is offered as a regional public good for any entity to deploy and use in any case that complies with the regulation, and is completely free of charge. The technology used is Hyperledger Besu.
What are the unique features of the platform?
- It is open, establishing an ecosystem of different digital wallets that can gather information and generate individual credentials for each person about their health status.
- It is anonymous, guaranteeing privacy and data protection of information through the use of protocols and standards of sovereign digital identity.
- It is trustworthy, as it registers pseudonymous information publicly on LACChain’s blockchain network.
- It is inclusive, because it works for everyone equally and its benefits will be transversal both for those who share their data and for those who are not able to do so.
How will DAVID19 make COVID-19 a visible enemy?
The tool will collect key information from each person, securely and anonymously, about symptoms or confinement status in order to have a real-time picture of how the virus is progressing.
What exactly does the app intend to show?
The objective is to build, without revealing personal data, a regional map of how the COVID-19 moves and evolves in real time. The idea is to collect the information provided to understand who has followed isolation measures, who has shown symptoms, and so on.
How reliable is the shared data in DAVID19?
The reliability of the data in DAVID19 depends on the truthfulness of the self-reported data of each person. That said, like a survey, the sum of data in a methodological way results in a mass of information that, as it increases, reduces the margin of error and gives greater reliability to the real-time picture that will be shown in the DAVID19 risk map.
Moving forward, DAVID19 has the functionality to validate this data with the appropriate authorities, also guaranteeing users’ privacy.
Is this data official or validated by the participating entities?
The aggregated data is not official, nor is it validated or supported by any of the participating entities.
What will the aggregate data be used for?
LACChain’s aggregated data should not be the basis for health-related or other decisions by participating authorities or citizens. If, in the future, the data is verified by the appropriate authorities, then decisions can be made on the basis of the data provided.
