Research on the Database Model Supporting the Setting and Sharing of Data Security Levels in Ubiquitous Smart Learning Spaces

In response to the need for learners in ubiquitous smart learning spaces to communicate with others while maintaining personal privacy, we propose a new model to address these issues. 1.How to ensure the security and reliability of data during transmission. 2.How to ensure the safe and classified storage of learners' data in space. This paper first analyzes the importance of data protection in the ubiquitous smart learning network space. Then, a four-level database model is constructed based on different permissions and encryption technologies for storing data, with each level of the database physically isolated. Learners can freely choose to store their personal data in the corresponding level of the database. Finally, the efficiency of the model was verified under simulated experimental conditions, and the security of this storage model was analyzed.
