The corona-app: how it works, and know about your privacy

The Dutch corona Corona Detector app from being tested today by several hundred residents of Twente. RTL News tech journalist Daniel Verlaan the app and also answers the seven most pressing questions.

1. What does the corona app exactly?

The corona application monitors with bluetooth watch who you’ve been around and will only work if both people have the app installed. Based on Bluetooth signals or see the app, how long and how close you’ve been to another. The app could measure with a substantial reliability ‘if you were dangerously close to an infected person.

The app should help sort out the health authorities who corona patients have been in contact. Those people may be infected and can be alerted about the app. This allows them to more quickly isolate and prevent the virus they in turn pass on to others, hoping the government.

2. How does the app?

The app throws all the time ‘digital dice “and exchanged their results with other phones that have the corona app. Both users of the app and the Ministry therefore does not know who is who: they see only random numbers that give contact time proposals.

Once someone is infected, the person can choose to send their digital dice to a central server. That server then sends the dice installed again to all the people the app. Locally on the phone then check whether you have been in contact with an infected person. If so, you get a warning message.

The app starts showing some information screens. So Corona detector states that are not saved and location data is not stored your name or other personal information. Then asked if you want to turn on Bluetooth and to use the new Bluetooth technology from Apple and Google. This is called ‘COVID 19-exposure.

After that the app running and it runs in the background. In the app you can read what to do if you received a notification that you’ve been in contact with a person infected with coronavirus. You can also request a corona test and you sign yourself that you’ve corona

3. The others are out as soon as you’ve corona?

If you’ve had a corona test and you’re infected (tested positive), you can indicate this in the app. You have there the possibility of your dice of the previous fortnight upload. The GGD confirmed infection with a unique code that you find in the app, to prevent people spreading nepbesmettingen.

The people with whom you have been more than 10 minutes in the area will see an anonymous report in their app. In that report states that more risk of infection and that you should keep your complaints properly monitored. If you develop symptoms, you can get a corona test plan from within the app

But I did something about COVID-19 on my Android or iPhone?

That can be good. Apple and Google have developed a Bluetooth technology to record classroom. This technology has been rolled out for Android via an updated Google Play Services and is available for all devices running at least Android 6.0 (from 2015). IPhone is the technology with iOS reached 13.5 available, which works on all iPhones from the iPhone 6S and SE.

The Dutch corona app uses this technology. If this app does not have installed the Bluetooth tracking technology inactive.

4. How is privacy friendly Corona Detector?

Corona detector can access your Bluetooth connection and saves only the outcome of the digital dice locally on your device on. No further information is processed, according to the application. If you’re infected with coronavirus, you yourself can choose your dice to the server upload.

With Android devices is the slightly different: there needs Corona detector can access the location. This is necessary because apps have to ask also access the site scanning Android via Bluetooth to other devices. That Corona detector does not, but the message will get to see it.

The contact with the server also raises the necessary privacy questions. A phone has a traceable internet address for the device, known as an IP address. And ISPs could see who dice sends to the server. For Internet providers to fool the app sends sometimes nepdobbelstenen. That way they do not know who is actually infected.

In addition, IP addresses on the arrival of the server directly filtered and discarded, he said Ivo Jansch, the technician responsible for the technical back of the app, rather against RTL News.

5. How much battery consumes Corona Detector?

It is currently unclear, but it seems that the app will consume between 3 and 6 percent of the battery. It is especially to use, type of phone and the life of your battery.

6. Why do not European corona app?

Countries have chosen to each build their own app. The Dutch Corona detector must work together in some other European countries with other corona apps. Has given the European Commission’s mandate. The exchange of these digital dice only when the app chooses the same privacy friendly anonymous model, such as Germany and Italy.

In France, where the corona app in a few days, a million times is downloaded, the exchange does not work. The country uses a less privacy-friendly app.

7. When can I use the app?

The app is tested at the time by several hundred residents of Twente. From these test should show whether the app is easy to install and wording calls misunderstandings. Mid July – is expected July 15 – the Cabinet decision of Corona detector is rolled out nationwide and everyone is downloading. The app is not yet in the App Store or Google Play to download.
