System allows surveillance cameras to ‘talk’ to the public through individual smartphones
Purdue University researchers have created a technology that allows public cameras to send personalized messages to people without compromising their privacy.
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.
