Method and system to provide multi-factor authentication for network access using light

An apparatus comprising:

• a network interface unit that enables network communications;
• a processor, coupled to the network interface unit, and configured to:
• receive a request from a device requesting access to a network;
• cause a code to be transmitted in light emitted by one or more light fixtures within a physical space in which access to the network is to be restricted;
• receive information from the device requesting access to a network;
• and
• determine whether to permit the device access to the network based on the received request and on whether the information received from the device is derived from the code transmitted by the one or more light fixtures indicating that the device is within the physical space.

A non-transitory processor readable medium storing instructions that, when executed by a processor, cause the processor to:

• receive a request from a device requesting access to a network;
• cause a code to be transmitted in light emitted by one or more light fixtures within a physical space in which access to the network is to be restricted;
• receive information from the device requesting access to a network;
• and
• determine whether to permit the device access to the network based on the received request and on whether the information received from the device is derived from the code transmitted by the one or more light fixtures indicating that the device is within the physical space.
