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.<\/jats:p>","DOI":"10.3390\/s21134501","type":"journal-article","created":{"date-parts":[[2021,7,1]],"date-time":"2021-07-01T02:44:39Z","timestamp":1625107479000},"page":"4501","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Reasons and Strategies for Privacy Features in Tracking and Tracing Systems\u2014A Systematic Literature Review"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2430-0449","authenticated-orcid":false,"given":"Christian","family":"Jandl","sequence":"first","affiliation":[{"name":"Department Medien und Digitale Technologien, University of Applied Sciences, 3100 Sankt P\u00f6lten, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6619-6494","authenticated-orcid":false,"given":"Markus","family":"Wagner","sequence":"additional","affiliation":[{"name":"Department Medien und Digitale Technologien, University of Applied Sciences, 3100 Sankt P\u00f6lten, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9220-649X","authenticated-orcid":false,"given":"Thomas","family":"Moser","sequence":"additional","affiliation":[{"name":"Department Medien und Digitale Technologien, University of Applied Sciences, 3100 Sankt P\u00f6lten, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8142-0255","authenticated-orcid":false,"given":"Sebastian","family":"Schlund","sequence":"additional","affiliation":[{"name":"Institute of Management Sciences, University of Technology, 1040 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"394","DOI":"10.1016\/j.jfoodeng.2009.02.004","article-title":"RFID smart tag for traceability and cold chain monitoring of foods: Demonstration in an intercontinental fresh fish logistic chain","volume":"93","author":"Abad","year":"2009","journal-title":"J.
