Firstly, the research studies the coding rule of the PDF417 barcode and designs related computer code algorithm, with making it programmed, and completes the coding part of the system software. Next, the coding and decoding principle of Reed-Solomon error-correcting code is briefly introduced. According to thecoding and decoding principle in galois field GF(929), to analyze and study its practical application with emphasis in this topic. Then, the PDF417 barcode decoding process is analyzed and studied detailed according to the barcode coding principle, with the corresponding realization method designed, improving the design in theory aspect by using material example, at the same time programming the design method to complete the decoding part of the system. Finally, validated the system program in the practical application of image information aspect, by using the nonrepeatability and the randomicity characteristic of Julia mark shape artwork.
