Infection Alert Apps

Health apps can save live,
when connected to a network,
holding contact links and health status.

National trust centers
hold those contact lists
without any personal data.

Alert system process

See how the infection alarm system can save your life.

Basic principles

The XIAnet architecture is currently focussed on the SARS-CoV-2 virus and the Covid-19 disease. But the mathematical model in the server software works on key parameters from a disease database and can be also used for any other pandemic infection.

Technical features in a glance

How XIAnet is working

  • When an infection is reported or one checks his/her status, the current contact list is sent to the trust center.
  • Trust center crawls the contact chains, checking multi-level references to infected people.
  • If a contact belongs to another country (=trust center) the grid is going to share multi-country contact relations on a need-to-know basis (only directly connected contacts).
  • At no time a trust center is able to know to whom a contact ID belongs to.
  • The only information sent to the trust center is the anonymous unique ID, the contact’s IDs, the date and duration of the contact.
  • We value your data privacy! At no given point in time any party will be able to read your personal information, location or that of your contacts.
  • Based on infection status, severity, contact level and some disease key data, a personal risk score is calculated by a mathematical model.

Scientists collect date from international authorities of all concerned countries – which are WHO, CDC (USA), ECDC (Europa), but also from other regional sources.

Without containment activities

Contribute!

XIAnet can only work, when all infection alert apps communicate with the same trust center per nation.

Therefore we ask you to join the initiative.

We need you as partner no matter if you are

  • an app developer
  • a national health ministry or other national health authority
  • an end user who likes to use any of these apps.

Share!

We ask you to share this document.

App developer

Develop your corona killer app
  • build UUID on installation
  • collect contact data via bluetooth
  • store contact IDs (date and duration)
  • allow user to send infection status
  • and contact list to trust center

Health authority / Government

Provide trust center
  • get the free trust center software
  • set up trust center cloud server
  • (we can do this for you)
  • set up communication to other trust centers

App user (everyone)

We need at least 50% of active adult people to use the health apps
  • download & install any XIAnet app
  • let bluetooth switched on
  • live with normal behaviour
  • check status at least once a day
  • in case of an infection report your status asap

App developers

As an app developer you can create your app based on the principles below.

  • 1. Bluetooth
    Use bluetooth to share contact IDs, date and duration only when they are in infection range for longer than half a minute.
  • 2. Summarize
    Condense contact list per day and store locally in the devices secure store. Save only the contacts UUID, the date and the cumulated contact duration. And delete list entries elder then the maximum incubation period.
  • 3. Ask for Symptoms or a TAN
    Ask user for symptoms or a TAN provided by a test center or doctor. TANs are provided by the trust centers only to official test centers, doctors and clinics. The user receives an individual TAN together with the test result or the diagnosis.
  • 4. Send status and contact list
    Send the local contact list and the user status to the trust center using our API. In return you will receive the individual risk score and information about critical contacts. You should do this only by request of the user or cyclically when specified in the apps setup. The cycles should be more than 2 hours.
  • 5. Notification
    When the risk score exceeds a level entered by the user in the app setup, send a push notification to the user and give behavior advices according to the risk level and the recommendations of the national health authorities.
  • 6. Earn?
    You are allowed to make money with your app. It's your decision if you like to do so or if you like to donate the app.

Government / Heath authorities

As a national government or heath authority, it’s up to you to setup a national trust center. It will be a public cloud server serving as the backbone for the infection alert apps.

Governments can profit from this by increasing the test efficiency and detecting infection chains. The ability to warn users can support a better timed isolation strategy and help kick-start the economy earlier than expected.

  • 1. Discuss
    Discuss your strategy against infection spread with all responsible political actors.
  • 2. Get consulting (optional)
    Receive aid on how your national infection prevention strategy can be developed.
  • 3. Organize server hosting
    Find a hosting provider for your national trust center server.
  • 4. Set up server
    Use our free XIAnet backend software to facilitate your trust center server.
  • 5. Mesh / Grid
    Set up agreements with other countries to share multinational contact relations with their trust centers. Setup the technical connection on your trust center server.
  • 6. Publish
    Publish that your server is online and ready for use for mobile apps.

The XIAnet initiative

We are not selling any apps.

We are even not selling our national trust center software.

We just like to promote a secure and international solution to defeat pandemic infections.

You may support our cause by donations or by requesting consulting services. Or just by sharing the concept with a broader audience. Together we can build a better future and face the current virus (and any others to come) head-on.

We are IT professionals, we developed the server software and we can do even more…

Our main profession is project lead, consulting and developing software solutions for medium and big companies running SAP ERP or S/4 HANA.

Apps, running on XIAnet

Sorry

Currently there is no app running under XIAnet.

If you are an app developer, connect your app to your national trust center running the XIAnet server software and get your app listed here.
