Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic credentials, and more particularly to an education electronic credential application method and system based on a blockchain. BACKGROUND

[0002] An electronic credential service system can provide comprehensive electronic credential services for schools and students in the education system, thereby helping to build an electronic credential application scenario from top to bottom and in a coordinated manner, which is of great significance and application value. The electronic credential service system includes all scenarios using entity proof files and various social scenarios requiring identity verification of personnel. Therefore, a trusted, accurate and automated electronic credential service system needs to be established.

[0003] Prior to the present application, existing electronic credential service systems are mainly designed for the encryption process of electronic credentials, but do not involve how to combine information accuracy and integrity to verify and chain the unified structure of electronic credentials and maintain information. This makes it possible for the electronic credential service system to have incorrect or incomplete information enter the blockchain system. In addition, since the traditional blockchain uses a broadcast method that may leak personal information, it is not clear how to adapt to the setting of the electronic credential broadcast method through the blockchain in the education system, which leads to the fact that an electronic credential service system based on blockchain technology has not been adapted to the education system.

[0111] S304. When the entered information is a verification level, the entered information is automatically uploaded to the on-chain query module as a to-be-verified certificate information.

[0112] In the embodiment of the application, the authority level is determined according to the entered information, if it is a query level, a query command is issued, and if it is a serious level, a certificate information update is issued.

[0113] Figure 4 is a flowchart of a method for applying an education electronic certificate based on a block chain in an embodiment of the application. After receiving the information update command, if the certificate error is below the preset range, the entered information is stored as to-be-chained information, a chain broadcast command is started, otherwise an information error command is fed back to the user.

[0114] As shown in Figure 4 in one or more embodiments, preferably, after receiving the information update command, if the certificate error is below the preset range, the entered information is stored as to-be-chained information, a chain broadcast command is started, otherwise an information error command is fed back to the user, and specifically includes:
