Anonymity and security

How will ProteGO Safe version 4.0 based on Exposure Notifications ensure user’s anonymity and data security?

Distributed system:

1. Data is stored on users’ devices. All information (entries in the Health Journal), as well as the history of devices encountered are stored on users’ devices and analyzed there.
2. Data entered into ProteGO Safe allows users to remain anonymous. It is not necessary to register or provide any identifying information. In addition to installing the application, the user only provides his nickname, which can be any, and its only purpose is user comfort.
3. Only people who are medically verified as patients with COVID-19 will be able to initiate the process of sending their Diagnosed Keys (prior to this, Contact Center has to reach the Patient to get a consent to enable appropriate export gateway for data upload - it's required - this consent is made voluntarily by a sick person, thus Contact Center has no means nor rights to do so on behalf of the patient by itself) so that they can send a warning to other users.
