Abstract

Methods, systems, and apparatuses are described herein for improving the security of computer authentication using light communications data provided by, e.g., environmental Li-Fi light sources. A mobile device may receive light communications data from a light source, such as a Li-Fi-enabled light bulb in a physical environment of the mobile device. That light communications data may indicate a variation in a modulation of light intensity of the light source over a time period. That variation might be used to provide a time- and/or location-specific key. The mobile device may determine the key by processing the light communications data and transmit a request for content that comprises the key. Access to content may be provided to the mobile device based on the key.

Claims18

Dependent claims

A mobile device comprising:

one or more processors;
and
memory storing instructions that, when executed by the one or more processors, cause the mobile device to:
receive, via a light-sensitive device and from a light source in a physical environment of the mobile device, light communications data that indicates a variation in a modulation of light intensity of the light source over a time period by:
determining, using a Global Positioning System (GPS) module of the mobile device, GPS coordinates corresponding to the mobile device;
determining, based on the GPS coordinates, a predetermined framerate;
causing one or more cameras to record video at the predetermined framerate;
and
determining the light communications data by processing the video, wherein the light source is configured to transmit different keys on a periodic basis;
determine a key corresponding to the light source and the time period by processing the light communications data;
transmit, to a remote server, a request for content, wherein the request for content comprises the key;
and
receive, from the remote server and based a determination that the key is associated with the physical environment, access to the content.

10 more elements

One or more non-transitory computer-readable media storing instructions that, when executed by one or more processors of a mobile device, cause the mobile device to:

receive, via a Li-Fi receiver and from a Li-Fi transmitter in a physical environment of the mobile device, light communications data that indicates a variation in a modulation of light intensity of the Li-Fi transmitter over a time period by:
determining, using a Global Positioning System (GPS) module of the mobile device, GPS coordinates corresponding to the mobile device;
determining, based on the GPS coordinates, a predetermined framerate;
causing one or more cameras to record video at the predetermined framerate;
and
determining the light communications data by processing the video, wherein the Li-Fi transmitter is configured to transmit different keys on a periodic basis;
determine a key corresponding to the Li-Fi transmitter and the time period by processing the light communications data;
transmit, to a remote server, a request for content, wherein the request for content comprises the key;
and
receive, from the remote server and based a determination that the key is associated with the physical environment, access to the content.
