For example, with respect to privacy, an App that implements Contact Tracing does not need to know Personally Identifiable Information such as the App User’s medical record number; while an App that implements Home Monitoring cannot be effective without the very same medical record number. So it would not be useful to establish a single baseline for global best practices without taking the specific features into account that an App implements.
- start with the assay for one of the App on this site;
- follow the links to the description of the features and implementation choices made by this App; and
- from there, you can investigate other implementation choices that the App Creators could have made, including those that currently constitute world-wide best practices on this subject.
For example, the German contact tracing app Corona-Warn-App shows it implements these main features:
and makes these key implementation choices:
Selecting one implementation choices, for example, “User is anonymous”, leads to a description of this choice, in relationship to other choices that the App Creators could have made instead:
These are documented with various pro’s and con’s, e.g. with respect to privacy or effectiveness.
