Apple and google are still working on an app they want to be used worldwide to help fight COVID-19 infection, even today They went one step further by showing us the example of the application and how we would be notified of the potential exposure.
Apple has created the app as an example for all countries it accepts, its source code is available to download and use as the basis of the program that each country wants to develop, and that helps us know more about the effectiveness of this "monitoring" program that will let us know if we were exposed to who was infected with Coronavirus and so we may have an infection problem.
In the screens we see in the article it is shown how the person was found when found you must validate it in the application by using a unique code that you can verify that it is actually a real infection and not in the misuse of the application. After completing a series of details such as the date of the test and authorizing the app to monitor your most recent contacts, all those who have been in contact with this person will receive notification of necessary safety measures.
Not anyone who has crossed your path will receive that notice. Variations such as contact type, activity, time in which communications were kept and what happened will be appreciated. With all this data, risk levels will be established that will be used to assess the actual risk of these contacts., and only those who exceed a certain standard will be notified. The app will also be able to notify the number of contacts, depending on the initial accident rate, as can be seen in this picture.
Apple has also made it clear that privacy is guaranteed. For example, The app will not be able to use our geolocation at any timeHe will not know where we are or where the contact happened, only that it is happening. The identity of the participants in the program will not be known, and it will be a program that can only be used by public health organizations. Apple's view is that there is one app in each country, or it leaves the doors open for the app to be developed in the region instead of the rest of the world.
