Modern information technology empowers education and infuses new vigor into educational innovation. However, current university diplomas are old-fashioned, not connected to information technology, and easy to copy. Two-dimensional code technology, widely popular in China because of its intuitive, simple, convenient, and other advantages, should be integrated into the field of education. Two-dimensional code technology is the advanced form of graphic code technology. However, through the analysis of the current situation of graphic code technology research and education applications including two-dimensional code, there are no actual cases of graphic code technology applied to graduation certificates, leaving a blank field of research. This is mainly due to the defects and limitations of the existing graphic code technology, so a new intelligent graph element technology (IGET) is proposed here. Intelligent graph element technology integrates the functional advantages of two-dimensional code and overcomes the issues of certificates being easy to forge and difficult to verify, by adding intuitive, discernible, and valuable new functions, suitable for the functional requirements of the graduation certificate. Based on intelligent graph element technology, a novel graduation certificate management system model is constructed here, and a graduation certificate is designed and implemented. Compared with the traditional graduation certificate, the graduation certificate based on intelligent graph elements has the advantages of being intuitive and readable, and having information security, a large amount of information, and intelligent anti-counterfeiting, verification, and traceability mechanisms. The application of intelligent graph element technology in the design and research of college graduation certificates opens a new window of digitization and informatization innovation for traditional college graduation certificates, and provides reference for other innovative applications of intelligent graph element technology in the field of education.
