The rule comparison program 510' is then in the order defined by the rule set 509. The meta-array and cull specific characters or segmentation symbols 514 to compress the encoded information. In the above example, the Chinese address is defined by the rule set 509. The rule comparison program 410 is executed by the county, city, and road, and the address is cut into 950 Taitung County, Taitung City, Minghua Road, and 88th Lane 88, No. 88, and the information and words of each section. The word set 512 performs a word matching program 511 to determine whether it is an address-specific word 513. For example, the postal code number "950" and the "Taitong County" word are synonymous with the specific word '; the words corresponding to the specific word will be met. Word culling 514, replacing a specific word with a single or single word or one of the two: if the postal area code is used, 950" without taking, Taitung County, the word; Words, remove them, optimize the arrangement according to the address cutting information, and finally encode the address into the bit string 515. ° Finally, arrange the text, address and other information encodings to start the identification application, start 6〇丨The 2D barcode 602 image is obtained by the lens device, 12 1325235 is used as the input of the barcode reading program 603, and the barcode reading program 603 confirms whether it is the identifiable barcode 604 according to the barcode definition rule. The bar code is subjected to an error check code or an error correction code 605. If the bar code encoding information is correct, the result bit string of the bar code reading program 603 is used as an input of the decoding program 607 to perform a decoding operation, and the information combination program 608 decodes. The output of the program 607 is combined in a string, and the user can select the outgoing call 609, transmit the message 610, add to the contact 611, transmit the email 612 or cancel according to the output result of the information combination program 608, and finally end the 611 reading decoding. Please refer to FIG. 7 , which illustrates a system and method for encoding and decoding two-dimensional barcode information according to a preferred embodiment of the present invention, and relates to a decoding method for a decoding program. The decoding program receives a wait for decoding. The bit string 701 first determines whether the 702-bit string is decoded for the text according to the barcode blocking attribute. If yes, the code comparison 703 is performed to determine whether there is a predefined code 704. If so, the code is replaced by the program 705. Secondly, it is interpreted as address decoding 706. If yes, the rule set 707 is loaded, and the address information 708 is cut according to the rule to perform a specific word ratio. Yes, if there is a specific word defined by the word set 709, the address specific word is restored by 710, and then the address string 711 is combined according to the rule; finally, the block information is decoded according to the bar code definition, and each area is The block information is combined into a string 713, and the result is displayed 714 on the output interface.
