"Reasons and Strategies for Privacy Features in Tracking and Tracing Systems-A Systematic Literature Review";
Sensors, 21 (2021), 13.

In the course of the digitization of production facilities, tracking and tracing of assets in
the supply chain is becoming increasingly relevant for the manufacturing industry. The collection
and use of real-time position data of logistics, tools and load carriers are already standard procedure
in entire branches of the industry today. In addition to asset tracking, the technologies used also offer
new possibilities for collecting and evaluating position and biometric data of employees. Thus, these
technologies can be used for monitoring performance or for tracking worker behaviour, which can
lead to additional burdens and stress for employees. In this context, the collection and evaluation
of employee data can influence the workplace of the affected employee in the company to his or
her disadvantage. The approach of Privacy by Design can help to benefit from all the advantages of
these systems, while ensuring that the impact on employee privacy is kept to a minimum. Currently,
there is no survey available that reviews tracking and tracing systems supporting this important
and emerging field. This work provides a systematic overview from the perspective of the impact
on employee privacy. Additionally, this paper identifies and evaluates the techniques used with
regard to employee privacy in industrial tracking and tracing systems. This helps to reveal new
privacy preserving techniques that are currently underrepresented, therefore enabling new research
opportunities in the industrial community.
