A diploma is a document that certifies that a student has successfully completed his courses of study and has been granted by an educational institution (such as a college or university). Obtaining a diploma leads to a better job. However, in recent years, it has been observed that employers can hire unqualified individuals for specialized roles. Fake degree certifications are on the rise because of new technologies and are worth over a billion dollars. The two most significant and inventive technologies of the past ten years are blockchain and the Internet of Things (IoT). IoT refers to the gathering of connected objects with one another via wearable technology and software for online data exchange and communication with other devices. Blockchain technology, on the other hand, is one way to ensure that diplomas are authentic. Several distributed and cryptographic techniques and algorithms are employed by Blockchain, a distributed hyperledger. Overcoming security risks and vulnerabilities in the educational field is an essential prerequisite to developing a robust IoT-based Learning Management System. An IoT-based LMS is a revolutionized suggestion in the educational environment as it offers software programs or web-based technologies in a transformed learning system and also in the administrative system of an educational institution. An IoT-based LMS is promising security. The goal of this article is to demonstrate how to eliminate diploma fraud using a private blockchain and IoT-based secure decentralized learning management system (LMS).Our recommended algorithm using a machine learning model based on blockchain systems, has as a result the decentralization, security, invariability, and transparency of diploma verification data. The conclusions of our method ensure whether diplomas are authentic or fake, offering potential jobs to graduates.
