Abstract:
1. A method for exchanging electronic information data, using a color barcode having a plurality of color values made of a combination of n-bit of red, green, and blue color parameters, in which the color values correspond to a plurality of predefined legend, the method comprising: (a) selecting the electronic information data from a first computer; (b) encoding the selected electronic information data into a barcode data containing a plurality of cyan, magenta, yellow, black (CMYK) values corresponding to the selected electronic information data; (c) transmitting the barcode data to a second computer; (d) printing the color barcode with a red, green, blue (RGB) only barcode printer, wherein the color barcode corresponds to the barcode data; (e) reading the color barcode with a barcode scanner; (f) detecting a plurality of optical wavelengths from the color barcode from red, green, blue (RGB) photo diodes collecting light signals from the color barcode; (g) confirming a start margin, a stop margin, a start character, a stop character, a data character, and a check character, by checking the detected photo wavelengths; (h) measuring a spectral diffraction intensity of light, which is emitted and reflected from a light emitter of the scanner as spectral diffraction intensity data by a 1,024 channel array detector; (i) arranging the measured 1,024 spectral diffraction intensity data to correspond to a plurality of optical wavelength values ranging from 380 nm to 780 nm; (j) calibrating a spectral diffusion intensity value of the array detector according to each of the plurality of values corresponding to the plurality of optical wavelengths; (k) organizing the calibrated spectral diffusion intensity value as a graph; (l) obtaining color values kX, kY, and kZ, and color coordinates x, and y; (m) setting up a corresponding variable value in accordance with a plurality of coordinates values having coordinates of CIE system of color specification; (n) determining a criticality value; (o) decoding the color barcode into a preferred data format which is secured by comparing criticality value and a rate of error; and (p) transmitting and printing out the electronic information data.
