scope:

The present document provides a review of existing pandemic proximity detection methods, applications and other aspects of a pandemic contact tracing system. The similarities and differences of the various available or upcoming approaches are examined, particularly concerning but not limited to the degree of interoperability, security aspects, use of centralized or decentralized approach, use of particular proximity detection methods and technologies, support of different device platforms, epidemiological value and privacy aspects.

The review includes a grouping of various approaches into several similar types (e.g. centralized or decentralized system) and provides examples of initiatives to which the approaches apply. The present document is also neutral in terms of technologies and initiatives; however, the focus is on initiatives involving proximity sensing and networking using mobile devices, and the applications and other technical enablers which can be installed on the devices.

The present document provides a basis for the analysis of suitable requirements for a standardized solution as specified in ETSI GS E4P 003 [i.1]. It also relates to ETSI GS E4P 006 [i.2], ETSI GS E4P 007 [i.3] and ETSI GS E4P 008 [i.4].
