Custom training plans can significantly increase students’ athletic performance. However, the students’ private data, such as body index, is required to generate the training plan, during which there may be data leakage. This paper presents a Blockchain-aided Physical Education Information System (BPEIS), which is an Internet of Things (IoT)-based system for data security and management in physical education. B-PEIS seeks to provide a secure and flexible system that can be utilized in physical education (PE) for improving student fitness performance. To verify the system performance, an experiment is conducted. Experiment results show that the B-PEIS can meet the need of PE.
