The background module is used for being responsible for code generation condition query service of a user, wherein the code generation condition query service comprises the step of querying a third party payment channel whether the user has code generation capability or not, including whether the user is a wind control user, whether the user has arrears, whether balance is sufficient or not, and whether the user is in a blacklist or not;
the key management module is used for authorizing signature data management service, wherein the authorizing signature data management service comprises the steps of recording the condition that a user acquires authorizing signature data and the acquisition times of the authorizing signature data on the same day, and setting expiration time of the authorizing signature data;
the key issuing module is used for authorizing signature data issuing service, and the authorizing signature data issuing service comprises the steps of acquiring and sending user data, a user public key and authorized signature data expiration time to an encryptor;
The encryptor is used for authorizing signature data to generate service, and is used for generating authorizing signature data according to the information sent by the received key issuing module.
5. The public transportation-based identification code transmitting system according to claim 1, wherein: the code generation client comprises an account management module, an identification code generation module and a mode switching module;
the account management module is used for enabling a user to register and log in an account;
The identification code generation module is used for acquiring authorization signature data or emergency authorization signature data from the main code generation module or the emergency code generation module to generate an identification code;
The mode switching module is used for monitoring the code generation condition query interface and/or acquiring the authorization signature data interface, if the code generation condition query interface and/or acquiring the authorization signature data interface are/is not responded after the preset time is exceeded, or the code generation condition query interface and/or the authorization signature data interface is/are detected to be abnormal, the mode switching module is switched to an emergency mode, the emergency code generation module is started, and the emergency code generation service is acquired from the emergency code generation module to complete code generation.
6. The public transportation-based identification code transmitting system according to claim 1, wherein: the identification code is a two-dimensional code.
