Our paper „Anonymized Counting of Nonstationary Wi-Fi Devices When Monitoring Crowds” got accepted at ACM MSWiM 2022! In the paper, we describe an approach to anonymously count nonstationary Wi-Fi devices (and only those!) when monitoring crowds. Previous anonymization approaches only allowed for the general counting of Wi-Fi devices, which included the counting of stationary devices such as printers or smart TVs. However, in crowd monitoring, only passengers should be counted via their nonstationary Wi-Fi devices such as smart phones to get accuracte counts. This is now realized for the first time through our novel anonymized counting method.
Welcome to the Safety-Security-Interaction Group!
The Safety-Security-Interaction group is concerned with the development of theoretically sound technologies for maintaining the security of IT systems in the context of safety-critical systems and the Internet of Things. The focus is on the development of security solutions that are tailored to the context-specific conditions and that take into account various types of user-interaction as well as the functional safety of the to-be-protected systems.
