Abstract
A system and methods by which a reconfigurable intelligent surface device is dynamically configured to control the reflection of transmissions made between an access point and one or more client devices so as to protect the transmissions from being properly received by an unauthorized device. These methods may be used to maintain data confidentiality, particularly for remote workers. The positions of the access point and client devices are used to configure the reconfigurable intelligent surface device to reflect the transmissions inward and avoid/minimize leakage outside a physical space.
