Abstract: A system obtains content access attributes associated with content presented at a user interface at a particular physical location. The content access attributes indicate intended accessibility of the content presented at the user interface at the particular physical location. The system obtains entity authorization attributes determined for an entity detected by sensors configured to obtain sensor data associated with entities positioned at the particular physical location. The entity authorization attributes are determined based upon the sensor data obtained by the sensors. Based upon the content access attributes and the entity authorization attributes, the system determines an interface security action for implementation at the user interface at the particular physical location.
