Embodiment 1

[0030] You can directly use hexadecimal for data representation, but this method directly doubles the storage space occupied by the data in the QR code. In the first embodiment, the space occupied by the encoding method of the present invention is slightly increased.

[0031] In an authentication application, a string of encrypted data needs to be stored in a QR code for authentication: the ciphertext (in hexadecimal notation) is as follows:

[0032] 96D36CA38854D4A1BC3E995ABFB620704BA06E3D8FC9D1E5E198C091035946BB01A83A6A91B9B06C

[0033] The above has a total of 40 bytes and 80 characters, grouped as follows:

[0034] 96D3 6CA3 8854 D4A1 BC3E 995A BFB6 2070 4BA0

[0035] 6E3D 8FC9 D1E5 E198 C091 0359 46BB 01A8 3A6A

[0036] 91B9 B06C

[0037] The corresponding conversion to decimal numbers is as follows:

[0038] 38611 27811 34900 54433 48190 39258 49078 08304 19360

Abstract

The invention provides a method for converting two-dimensional code contents into pure digital symbol codes. The method comprises the steps of storing binary data to be coded in a two-dimensional code as a byte array; performing division by taking two bytes as a group, and if one byte is left finally, enabling the final byte to serve as a separate group; and according to the groups, defaulting low address bytes in each group to high value bytes of digits, defaulting high address bytes in each group to low value bytes of the digits, converting each group of bytes into decimal Arabic digits, and combining conversion results into a string of Arabic characters. According to the method, a mode of transcoding first and coding second is proposed, so that the problem of high crash probability or unfriendly display of a universal two-dimensional code scanning device during two-dimensional code scanning is avoided, namely, binary contents unreadable for naked eyes can be converted into common Arabic digits; and original data is subjected to format transcoding, and a transcoding rule is determined, so that the occupied space is expanded a little after transcoding.

Description

technical field [0001] The invention relates to the field of two-dimensional codes, in particular to a method for converting content of two-dimensional codes into digital symbol codes. Background technique [0002] With the development of science and technology, there is an urgent need for barcodes to express more information in a limited space to meet the needs of various information transmissions, and two-dimensional codes have emerged as the times require. The two-dimensional code technology uses specific geometric figures to be arranged in the two-dimensional direction according to certain rules to form a special graphic mark, so as to realize the transmission of information. Two-dimensional code is a large-capacity two-dimensional code developed based on one-dimensional barcode and image processing technology. The content of two-dimensional code can store various characters and data, such as pictures and videos. With the rise of smart handheld terminals, QR codes have ...
