Development and study of content protection models for online courses

Abstract

The development and investigation of content protection models for online courses is an urgent task in light of the growing popularity of online education and the need to protect content from unauthorised access and distribution. The purpose of this study is to create effective and reliable models for protecting the content of online courses. To achieve the goal, methods of analysis of existing content protection systems and mathematical modelling were used. Models based on various security approaches, including cryptography methods, watermarks, and access rights management systems, have been developed and tested. The main result of the research was the creation of tools to protect the content of online courses, which includes a comprehensive protection system using cryptographic algorithms and watermarks. An access rights management system has also been developed, which allows restricting access to content only for authorised users. The results obtained confirm the effectiveness of using a combined content protection system and can significantly reduce the risk of unauthorised access and distribution of online course content. The practical significance of the study lies in the possibility of applying the developed models for protecting the content of online courses in practical conditions. They can be used in various educational organisations providing online courses, and in other areas where protection of digital content from unauthorised access and distribution is required. The use of the developed content protection models will improve the security level of online courses and reduce the risks of leakage of confidential information. Moreover, the developed models can be used as an example in the development of similar digital content protection systems in other areas. In general, this research has a high practical significance and can be useful for everyone involved in the creation, storage, and distribution of digital content.
