The team developed a real-time end-to-end system called PHADE to allow this process, known as private human addressing. While traditional data transmission protocols need to first learn the destination's IP or MAC address, this system uses motion patterns as the address code for communication. The smartphones then locally make their own decisions on whether to accept a message.

The PHADE system works using a server to receive video streams from cameras to track people. The camera builds a packet by linking a message to the address code and broadcasts the packet. [...] the mobile device automatically delivers the message to its owner.

PHADE can be used in places such as at a museum, where visitors can receive messages with information about the artifacts or exhibits they are viewing. [...]
"PHADE may also be used by government agencies to enhance public safety," Cao said. "For example, the government can deploy cameras in high-crime or high-accident areas and warn specific users about potential threats, such as suspicious followers."

Did they get the idea from the TV show "Person of Interest"?

No clue. I can imagine: "Citizen, your body language indicates anger. What's up with that?"
