New countermeasure against unwanted wireless surveillance

Smart devices are supposed to make our everyday lives easier. At the same time, however, they are a gateway for passive eavesdropping. To prevent possible surveillance of the movement profile within one’s home, researchers from the Max Planck Institute for Security and Privacy, the Horst Görtz Institute for IT Security at Ruhr-Universität Bochum and the Cologne University of Applied Sciences have developed a novel system for protecting privacy in wireless communication. The method, based on the technology of intelligent reflective surfaces, will be presented by the researchers on 24 May 2022 at the IEEE Symposium on Security and Privacy.
