What problems can the unified identity authentication system solve?

Strengthen privacy protection: Unified identity authentication can help users protect personal privacy, because the user's identity information only needs to be authenticated once and can be shared in different applications and services, avoiding the risk of privacy leakage caused by multiple provision of personal information.

Unified identity management provides the full life cycle management of the system itself and business accounts, and solves problems such as user name information content, inconsistent format, and inconvenient management. Unified identity authentication and provide digital certificatesA variety of identity authentication methods such as books and dynamic passwords reduce the difficulty of business system access to strong identity authentication means.

Query personal education, medical care, transportation, social security, provident fund information, etc. Personal identity information: resident ID card information, household registration information, personal income tax, etc. Education information: student registration information, school grades, student ID cards, etc. Medical information: health files, medical record information, medical insurance, etc.

Provide unified user identity authentication and authorization management for other smart campus businesses. Help teachers and students realize "single-point login, multi-point roaming", change the management of a group of accounts into one account, realize "No.1 Pass", and solve the problems of account and password management difficulties for teachers and students.

For government agencies, by accessing the unified identity authentication platform,It can effectively reduce the time and effort cost of user authentication, and can better protect data security and user privacy. For enterprises, institutions and the public, using the platform can more conveniently access government services and improve efficiency.

What are the methods of system verification test?

There are two main methods of system testing: manual testing and machine testing. ( 1) Manual testing. Manual testing, also known as code review, is to find errors by reading the program. Its content mainly includes checking whether the code and design are consistent: checking whether the logical expression of the code is correct and complete; checking whether the code structure is reasonable. ( 2) Machine test.

The basic method of system testing is: recovery test. Recovery test mainly checks the fault tolerance of the system. When there is a problem with the system, can you correct the error and restart the system within the specified time interval? The recovery test first uses various methods to force the system to fail, and then verify whether the system can be restored as soon as possible.

System testing is mainly to improve the reliability of the software and detect whether the software system meets the requirements of users. The system testing methods mainly include the following: black box testing. System testingBlack box tests are mostly used, mainly including multi-tasking tests, critical tests, interrupt tests, equivalent division tests, etc.

Recovery test, as a system test, mainly focuses on various conditions that cause software operation failure, and verifies whether its recovery process can be executed correctly. 2) Security test Security test is used to verify the internal protection mechanism of the system to prevent illegal intrusion.
