The rapid development of information technology opens up opportunities for the development of better services in the field of education. With internet services, the information that students have is not limited by space, place, time and distance. Created a network that does not have a service provider acting as a central authority and users have access to control information that avoids the presence of third parties. An alternative solution to today’s centralized networked learning systems uses the efficient and distributed Decentralized Online Educations (DOE). This platform uses blockchain technology as an educational data storage system that is used to solve academic privacy issues in a decentralized system. This study, created a manageable and auditable access control framework for Decentralized Online Education (DOE) using blockchain technology to discuss the definition of privacy policy.
