METHOD AND APPARATUS FOR TRANSMITTING, RECEIVING AND DECODING DATA USING ENCODED PATTERNS OF CHANGING COLORS

A system and method for encoding, transmitting and decoding data is described which defines a plurality of bit patterns into a predetermined color combination of red/green/blue colors. A message is formed from the plurality of bit patterns and the message is then arranged into a recognizable format with a message protocol. The message is transmitted to a decoder, which decodes the message and displays the message on a display. A use is provided to establish a two factor authentication mechanism to authenticate a user by a requester.
