METHOD AND APPARATUS FOR TRANSMITTING 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 RGB values. 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.
1 . A method for transmitting encoded data, said method comprising:
encoding a challenge response within a code series composed of a bit pattern sequence of color images, each of said images constructed from a combination of red, green, and blue color values ranging from a minimum value corresponding to black to a maximum value corresponding to white;
arranging said challenge response into a recognizable format with a message protocol;
transmitting said challenge response to a physical decoder adapted to decode said message into a challenge response; and
applying said challenge response to a challenge query.
2 . The method of claim 1 wherein said minimum value is greater than or equal to 0.
3 . The method of claim 2 wherein said maximum value is less than or equal to 255.
4 . The method of claim 1 wherein said transmitting step includes decrypting said challenge response.
5 . The method of claim 4 wherein said encoding step further includes encrypting said challenge response within said code series.
6 . The method of claim 1 wherein said defining step comprises a calibration sequence of at least one image adapted to normalize said color values.
7 . The method of claim 1 wherein said challenge response includes a challenge message comprising alphanumerics.
8 . The method of claim 7 wherein said decoder displays said alphanumerics.
9 . The method of claim 8 wherein a user manually inputs said alphanumerics as said challenge response.
10 . A method for transmitting encoded data, said method comprising:
defining a code series composed of a bit pattern sequence of color images, each of said images constructed from a combination of red, green, and blue color values consisting of a value corresponding to white;
encoding a message within said code series;
arranging said message within into a recognizable format with a message protocol;
transmitting said message to a physical decoder, with a sensor adapted to detect characteristics of said images, including intensity, adapted to decode said message into a unique challenge response; and
applying said challenge response to a challenge query.
11 . The method of claim 10 wherein said transmitting step includes transmitting said message to multiple physical decoders adapted to decode said message into a challenge response.
12 . A system for providing a light based token response, said system comprising:
an electronic visual display adapted to, and with a frame rate sufficient to, transmit a series of sequential color flashes corresponding to information in a recognizable format with an information protocol, said color flashes constructed from red, green, and blue color values ranging from a minimum value corresponding to black to a maximum value corresponding to white; and
a physical decoder, with a sensor adapted to detect a characteristic of said color flashes, configured to decode said information based on said series of sequential color flashes and convey said information as decoded.
13 . The system of claim 12 wherein said information includes a challenge response token component.
14 . The system of claim 13 further comprising a secured device bearing a challenge query.
15 . The system of claim 14 wherein said secured device includes said electronic visual display.
16 . The system of claim 15 wherein said decoder is adapted to convey and apply said challenge response to said challenge query.
17 . The system of claim 14 wherein said decoder is adapted to convey and apply said challenge response to said challenge query.
18 . The system of claim 12 wherein said sequential color flashes include a calibration sequence of at least one flash adapted to normalize color values of said color flashes.
