Authentication System of Online Student Profiles with Blockchain Algorithm

Nowadays, use of internet by more people made the demand towards online education increase. Together with the integration of education and technology, these trainings have become available as a new channel on digital platforms. Therefore, educational institutions, especially universities and private enterprises have started to offer courses they provide in physical settings in online platforms as well. Just as in the courses given in the physical settings, when the determined learning outcomes are achieved, this success is documented through certificates or diplomas. Although, the concepts such as educational content and student information in educational institutions' own information systems are not digitally portable and shareable, it still needs a lot of work flow based on manpower and physical documentation which carries qualities that lack behind the online technologies, unreliable and also not without integration problems. In the scope of this work, it is aimed to provide a system where the data of the educational background of individuals can be stored and verified using blockchain algorithms. Blockchain is a distributed recording system that can be shared by many parties, facilitating the recording of new processes while making it easier to monitor over the network of an unbreakable data set. Along with the fact that data security, verifiability and durability can be ensured in electronic form by using only blockchain, it also enables learning records to be stored and shared without a central authority. Another advantage of verifiability is to prevent imitation of the identity and documents of educational institutions and to protect the dignity of both academic and non-academic institutions. In addition to the basic facilities provided by the Blockchain system, the new possibilities and uses that come up with the combination of learning needs and technology are evaluated. It is an example of the fact that students are not limited to the educational opportunities of an educational iv institution but can also provide the educational resources of the fields they want to specialize from different educational institutions. The educational plans that can be obtained through digitalized data are considered as new advantages that can be offered to institutions and education designers. This study goes through an exemplary application design to address the assessments identified.
