System and method to prevent eavesdropping of IoT enabled object-user interactions

Abstract:

Disclosed embodiments provide techniques for data communication to mobile electronic devices utilizing nodes equipped with directional transmitters. The mobile electronic devices are classified as registered or unregistered. A current location for each mobile electronic device in an area is determined. A registered mobile electronic device is identified from a group of mobile electronic devices. Based on the determined location, a distance to a registered mobile electronic device from a transmitter is determined. The transmitter is a directional transmitter, capable of transmitting along a sector. A sector corresponding to the registered mobile electronic device based on an angle range and distance from a transmitter to the registered mobile electronic device is determined. Data is transmitted to the registered mobile device with directed communication from multiple transmitters, operating to create constructive interference to enable a suitable signal strength at the location of the registered mobile electronic device.
