HCCB Data Encoding and Decoding Data from Mobile

A barcode is an optimal machine-readable representation of data relating to the object to which it is attached. Encoding data using barcodes enables a significant decrease of work in comparison with the amount of work involved when data is entered manually. In this paper, a high capacity color two dimensional barcode uses the colors to increase the barcode data density. This is proposed by encoding data in individual color channels. Data encoded in cyan, magenta, and yellow channels are estimated from red, green, and blue sensor channels of a scanner, respectively. Data is encoded by modulating the orientation of elliptically shaped dots. The orientation based data encoding provides beneficial robustness against printer and scanner tone variations. By encoding data in individual color channels, the capacity of color barcode is increased. The color interferences are avoided by using error correction methodology. The security is involved through modify extraction of geometric distortion signature from a printed barcode, which can be used to identify the type of source printer. User can view the data from the color barcode by using their mobile phones.
