BACKGROUND OF THE INVENTION
A two dimensional (2D) barcode is a graphical image that stores information both horizontally and vertically to significantly improve its storage capacity compared to a unidimensional barcode. The 2D barcode is widely used as a marketing tool to allow users to quick access its digital content by scanning and decoding it using a smartphone due to its fast readability and greater storage capacity.
However, the storage capacity of the 2D barcode code is still not able to keep up with the demands of market as the requirement for the digital content size is increasing. Accordingly, it would be desirable to provide a method and system for generating 2D barcodes in a way such that the huge digital content can transmitted in an efficient manner.
PRIOR ART Patent document US8235303B2 discloses a two-dimensional code having a rectangular region is provided. In the rectangular region, there are code blocks composed of a plurality of cells, a first specific pattern specifying the positions of the cells, and a second specific pattern separating the code blocks from a background of the code. The first specific pattern is located at a specified corner of the rectangular region. The second specific pattern is located along one or more of first borders along which the first specific pattern is located, the first borders being part of the borders of the rectangular region. The code blocks include error-correction code blocks, which are located along second borders which are different from a border of the borders along which the second specific pattern is located. The second borders are part of the borders. Compressed data code blocks are also arranged in the same way as the error- correction code blocks.
Another patent document US20040020989A1 discloses a two-dimensional code having data cells (referred to as DC) comprising two-dimensional data, positioning finder patterns (referred to as FP) and an alignment pattern (referred to as AP) is input, the positions of FP are detected by evaluating the proximity from patterns in three horizontal, vertical and inclined directions. The position of AP is detected by conducting the template matching after the rotation correction of part of the input image. The version of the code is determined by calculation of the number of cells from the widths and positions of FP. Coordinate conversion expressions for converting the positions of DC into their coordinate positions based upon the positions of FP and AP and the version are determined and DC are cut out. The array of the cut out DC is decoded for reading the two-dimensional code.

The admin device has a camera for capturing the 2D barcodes from the client device and it contains software modules for decoding the 2D barcodes. The 2D barcodes can include Aztec Code, Code 1, ColorCode, Color Construct Code, CrontoSign, CyberCode, d-touch, DataGlyphs, Data Matrix, Datastrip Code, Digimarc Barcode, digital paper, DWcode, EZcode, High Capacity Color Barcode, Han Xin Barcode, HueCode, InterCode, MaxiCode, MMCC, NexCode, Nintendo e- Reader#Dot code, PDF417, Qode, QR code, AR code, ShotCode, Boo-R code SPARQCode, VOICEYE, or any combination thereof.
Each of the mobile devices can be installed with an application to provide a graphical user interface for users to interact with their devices and to initiate the data transfer operation. Preferably, the mobile devices are but not limited to personal digital assistants (PDA), smartphones, tablets, laptops, netbooks, phablets, phoblets, and any suitable means which capable of processing data, displaying the generated 2D barcode images and capturing the generated images.
Referring to Fig. 1, a process of encoding and generating RGB colour model 2D barcodes is illustrated. In step 101, a fragmenting module splits a data block into multiple small blocks with chunk number and total chunks amount encoded therewithin. In step 102, a 2D barcode encoder converts data chunks into 2D black & white barcode images. In step 103, a 2D barcode RGB multiplexer converts white colour region of the black & white barcode images into Red, Green, or Blue and then superimposes a Red image, a Green image, and a Blue image into one. In step 104, a 2D barcode frame multiplexer converts series of the coloured 2D barcode images into an animation of alternating barcode image frames for displaying on a display unit.
Referring to Fig. 2, a process of decoding the animation of barcode image frames is depicted. In step 201, the animation is captured by a smartphone camera. In step 202, a 2D barcode RGB demultiplexer converts the coloured 2D barcode frames into 2D black & white barcode images. In step 203, a 2D barcode decoder decodes images into data chunks. In step 204, a defragmenting module combines multiple chunks of small data blocks to form the data block.
The present disclosure includes as contained in the appended claims, as well as that of the foregoing description. Although this invention has been described in its preferred form with a degree of particularity, it is understood that the present disclosure of the preferred form has been made only by way of example and that numerous changes in the details of construction and the combination and arrangements of parts may be resorted to without departing from the scope of the invention.
