4 Basic Requirements

4.1 Compliance The organization that generates/assigns credit entity identifiers should have clear constraints on the allocation, use, query, and sharing of these identifiers. At the same time, a correction channel should be established to allow credit entities to raise objections and apply for correction of their identification information.

4.2 Dynamism Organizations that generate/assign credit entity identifiers should establish an information verification system and promptly update and record changes in the status of credit entities (such as enterprises). Information such as name changes or cancellations, name changes or deaths of natural persons, etc., enables dynamic management and traceability of identification information.

4.3 Normative A single credit entity can possess multiple types of identification codes simultaneously. All credit information systems should generate/assign identification codes to credit entities in accordance with these regulations. The identification information of credit entities should be entered and stored in accordance with the formats and requirements stipulated/defined by the relevant authorities, avoiding errors due to spelling, encoding, or formatting. Information mismatch can occur due to errors or other reasons.

4.4 Verifiability The agency that generates/assigns credit entity identifiers should support the rapid identification of credit entities through different categories/forms of credit entity identifiers. Cross-verification of retrieval and identity should be conducted, and technologies such as blockchain, big data, and artificial intelligence should be leveraged to improve information processing efficiency.

4.5 Security Organizations that generate/assign credit entity identifiers should establish mechanisms to securely control the use of these identifiers and prevent tampering. Misuse or forgery of identifiers may be addressed by using encryption, desensitization, or other measures to process credit entity identifier information when necessary.

5 Organizational Identification

5.1 Form Organizational identifiers include, but are not limited to.

a) Unified Social Credit Code;

DID allows organizations to have complete control over their identity information, deciding when and how to share it without relying on centralized institutions (such as governments, enterprises, or social platforms) for authentication.
