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.

“…A lot of research has been done in the context of IoMT in order to propose novel security systems based on multimedia data, e.g., retina or biometric scanning, voice recognition, and video surveillance systems [10]. In particular, video surveillance devices have become a key requirement for smart city application in order to ensure public safety for crime detection, residential or assisted living facilities [21], [22], industrial surveillance, and other critical spaces [23], [24]. In [21], an IoT residential surveillance system is designed.…”

“…Indeed, this concerns situations in which an attacker has already enough information and does not need to find vulnerabilities to bypass any protection mechanism. For this reason, the assumption of no background knowledge is commonly adopted in scientific literature [68]- [71]. Therefore, in our application context, through Assumption A.8, we assume that the attacker has no background knowledge about the monitored building (e.g., number of users in a building or area) or the users' movement habits inside it.…”

Anonymous Access Monitoring of Indoor Areas

Video surveillance of public spaces is a feature of modern society that has expanded quite quickly and in a pervasive way during the last decades becoming a fundamental need for both individual and collective security. But, as the sophistication of this type of systems increases, the concern about threat to individuals' right of privacy raises as well. Indeed, the video surveillance systems could breach personal privacy because location is clearly one of the most sensitive people information. Hence, preserving location privacy while achieving utility from it, is a challenging problem demanding the investigation of researchers. This paper tackles this non-trivial issue by designing a novel privacy-preserving architecture able to anonymously monitoring people access at the entrance of critical areas in an indoor space. At the same time our approach is able to provide full accountability in case of an accident or a legal requirement. Interestingly, our protocol is robust to server-side attacks and is efficient enough to be applied indoors through a set of IoT (Internet of Things) smart camera devices.

In this paper, we present a BeagleBone-based system to increase the security and safety level of critical environments by tracking people movements.Our solution is privacy aware, as it is possible to know who accessed a zone at a given time, with an uncertainty degree of accountability.The problem of accountability of people's access to physical environments is receiving great attention in recent times, also because of the emergent risk related to terrorism. Specifically, indoor tracking to allow a-posteriori identification of the authors of an illegal action is an important issue.Consider, for example, a security/safety incident occurred in a museum, which hosts thousands of visitors per day. Even though we have registered the entrance of all people and we are able to restrict the instant of the incident to a brief time interval, the number of suspects is so high that the adopted security measures are in fact ineffective. Besides video surveillance, an effective possibility of tracking people is based on the use of RFIDs, to have logs reporting people localization at any time and to restore precise information in a faster way than video surveillance. This kind of solution requires that people entrance in the surveillance environment is registered, but this is an acceptable (often already adopted) requirement in case of critical environments (e.g., government buildings, museums, safety-critical environments, tribunals).Unfortunately, in most cases, a similar solution is intolerable for privacy reasons, often not compliant with law requirements.In this paper, we study this issue by considering a surveillant environment in which people internal accesses must be logged for security purposes. However, a certain degree of uncertainty has to be introduced for privacy reasons. Specifically, it is required that, given an instant of time τ
