  • Method and system for providing secure communications between a first and a second peer device
    Patent number: 8271786
    Abstract: A method and system for providing secure communications between a first and second peer device is disclosed. The invention includes allowing the first and second peer devices to verify the authenticity of each other only while each peer device is within an established zone of privacy wherein the established zone of privacy is an area close (for example, almost touching) to the peer device. Because the authenticity of the other device is verified only while each peer device is within the established zone of privacy, users can visually confirm that there are no potential interlopers within the zone.
