1.1.2Main functions

1）Unified user management service. Unified users management provides services of centralized user information management, user account maintenance, password strategy management, and authorization management for applications of many businesses, which ensures the synchronization of the only ID account information and the account information of multi-application system within the unified users management system. Unified users management is the foundation for the realization of user’s ID sharing, unified ID authentication and multi-applications’ single login. Unified users management can get internal users and external users’ basic information through the tax human resource system and comprehensive collection and management system.

2）Unified ID storage service. Unified ID storage uses LDAP and supports relational database pattern, which is the major data storage resource of tax users’ ID information. It provides users’ ID information storage, application users’ accounts, authentication methods and authorized information storage for the unified users’ management. It also offers unified synchronization of users’ information for all application systems, provides authentication data of authorized users and ID authentication for the unified ID authentication service. It also is responsible for the synchronization and maintenance of users’ ID information for all levels’ storage systems.

3）Unified ID authentication. Unified ID authentication provides unified user ID authentication service and approves data based on the users’ ID information in the unified ID storage. Unified ID authentication service supports multiple authentication patterns, which include static password, digital certificate, dynamic password and SMS, to meet the needs of multi-security. After passing the ID authentication, users can access authorized application systems through single login service, realizing the ID authentication sharing among different application systems.

4）Single login. Single login service solves the multi-identified issues when accessing the multiple application system. Single login provides the users the access of all application systems’ service within the right of authorization through one time of authentication, which supports the crossing area authentication between central department and province department (“roaming”). Single login should support the working doors of the central department’s business.

5）Digital authentication application service. Digital authentication application service is based on the public key infrastructure (PKI), which supports the digital certificates signed by the three stage golden tax project’s authentication system and other digital certificates signed by other authorities which fit the requirements of the nation and taxing, providing the services of digital signature authentication, digital certification’s ID authentication, data coding and decoding, secure accessing and coding of distribution channels for the application system.
