Abstract: Optical wireless communication techniques are described and claimed. In one embodiment, the disclosure relates to method and apparatus to provide optical signaling with visible light having variable pulse position modulation (VPPM). The optical signal includes a Start Frame Delimiter (SFD) which indicates beginning of an asynchronous optical signaling. The VPPM signaling includes a lower frequency time varying amplitude component that when subsampled by a low frame rate camera results in alias induced flicker or blinking. Such signals are quickly recognizable as signals with modulated data. In another embodiment, the disclosure provides a system, device and method for decoding a Start Frame Delimiter (SFD) to indicate arrival of incoming VPPM optical data.

Abstract: Various systems and methods for identifying and performing authentication of visible light communications using optical camera communication techniques are described. In an example, an electronic processing system to authenticate a particular light emitting source includes electronic operations for: detecting, from image data, modulated light data emitted from a light emitting object, where the image data depicts the light emitting object, and where the image data is captured with an image sensor (e.g., of a camera); identifying, from the image data, the light emitting object as a source of the modulated light data; receiving an indication to select the light emitting object as an authenticated source of the modulated light data; and performing a command to process the modulated light data from the authenticated source, with the command performed in response to the indication to select the light emitting object as the authenticated source of the modulated light data.
