The number of data blocks occupies 1 byte (16-ary representation). The data content of each data block is encoded in the following format: the data content of each data block is divided into a plaintext coding Type, a class A encryption coding Type and a class B encryption coding Type according to the coding Type in the Type-Length-Value coding format.

The description of the Length first byte encoding is shown in table 3, wherein, when b8 of the first byte is 0, b7-b1 of the byte represents the Length of the Value field; when b8 is 1, b7-b1 is taken as the length of the following byte. The following byte identifies the length of the Value field.
TABLE 3 Length first byte encoding Table
In the embodiment of the invention, the binary code converted from the data identifier after the national encryption OID algorithm identifier 1.2.156.10197.1 is used as the algorithm identifier, the conversion standard accords with the series standard of ISO/IEC 8825, less than 3 bytes are complemented with 00H, and the plaintext is represented by 000000H. The coding of the OID accords with the OID identification specification jointly proposed by the ISO/IEC and ITU, and the specification of the application identification of the GM-T0006-2012_password can be seen. For example, the setting algorithm is identified as "000000H" for the plaintext type without encryption, and as "660000H" for the SM1 encryption algorithm.
For the algorithm additional information, two bytes are reserved as extension bytes to be described by applying the data encryption method. And encrypting the plaintext data by using the selected encryption algorithm for the encrypted data block to obtain corresponding ciphertext information, and determining the Value of the encrypted data block according to the coding format of algorithm identification, algorithm additional information and ciphertext information. For example, if the determined coding type is a type a encryption coding type, the plaintext information is "5130001000000017031280", the encryption algorithm is "SM4-ECB", the algorithm identifier is "680100", the algorithm additional information is "0000", and the encrypted ciphertext data is "7AC0CF055F8E9E3E02FC550a60a44427", the Value in the data content of the data block is "68010000007AC0CF055F8E9E3E02FC550a60a44427".
Setting the data Value of the Type A encryption coding Type to be 01, if the Length of the data block is 15, determining the data content of the data block to be '011568010000007 AC0CF055F8E9E3E02FC550A60A 44427' according to the coding format 'Type-Length-Value' of the data content of the data block.
If there is only one data block, i.e., the number of data blocks is encoded as "01", it can be determined that the service data is "01011568010000007AC0CF055F8E9E3E02FC550a60a44427".
In step 104, a cyclic redundancy check algorithm is used to calculate the service code and service data to obtain a check code.
In an embodiment of the present invention, the "service code+service data" is calculated using a cyclic redundancy check algorithm CRC16 algorithm to obtain a check code.
In step 105, the service code, the service data and the check code are combined to obtain two-dimensional code information for making a two-dimensional code image.
In the embodiment of the invention, the encoding format of the two-dimensional code information is 'service code + service data + check code'.
For example, if the service code is "020100", the service data is "010115a44427", and the check code is "EDE1", it can be determined that the two-dimensional code information is "020100010115a44427EDE1".
Fig. 6 is a flowchart of two-dimensional code generation according to an embodiment of the present invention. As shown in fig. 6, the method is divided into three parts of determining service codes, organizing service data and adding check codes.
For determining the service code portion, the service code is determined primarily based on the specific service category.
For organizing the business data part, the coding type is determined according to the security level of the plaintext information, and the corresponding data content is determined according to different coding types.
