Self-indentifying one-way authentication method using optical signals
First Claim
1. A mobile device, comprising:
- an image sensor;
a wireless interface configured to communicate through a network over a wireless medium;
a processor coupled to the image sensor and the wireless interface;
a memory; and
software in the memory to be run by the processor, wherein running of the software by the processor configures the mobile device to implement functions, including functions to;
operate the image sensor to capture one or more images including a modulated visible light signal transmitted from a visible light source located within a space, wherein the captured one or more images include a pattern of stripes;
determine from the captured one or more images a width of one or more stripes of the pattern of stripes;
determine, based at least in part on the determined widths of stripes in the obtained pattern of stripes, information corresponding to a geographical location of the visible light source;
store the determined information; and
process the determined information to verify that a user of the mobile device came into proximity of the visible light source.

Abstract
In one aspect, the present disclosure relates to a self-identifying optical transmitter for broadcasting a one-way authentication code using light-based communication. The transmitter may include a memory for storing an identifier of the transmitter, a processor for generating a data signal including an identifier of the transmitter, a modulator for receiving the data signal and generating an electrical signal, the modular generating the electrical signal by modulating the data signal. The transmitter may also include a light source for receiving the electrical signal, converting the electrical signal into an optical signal, and continuously broadcasting the optical signal as an optical data transmission stream. The optical data transmission stream may be used to verify that a receiving mobile device is near the transmitter. The transmitter may also include an optical surface for dispersing the optical data transmission stream as the optical data transmission stream is emitted from the transmitter.
