Secure Digital Rights Management in Gamified Personal Health Promotion Applications Using Attribute-Based Encryption

The rising prevalence of diseases linked to factors such as excessive alcohol and tobacco use, sedentary lifestyles, and poor nutrition has led to a greater focus on Personal Health Promotion (PHP) as a preventive measure. PHP emphasizes improving quality of life and well-being, driven by advances in medical technology, including virtual and augmented reality. However, as PHP systems grow in popularity, concerns over personal data security, such as account theft and information breaches, have become increasingly important. To address these concerns, this study proposes a game-based personalized health promotion system that integrates Key-Policy Attribute-Based Encryption (KP-ABE), key insulation, time-bound encryption. These methods ensure data security through hierarchical access control and dynamic time management, protecting personal health records and exercise prescriptions. The system also incorporates key insulation to enhance the security of private keys. This multi-layered security approach provides a robust solution for safeguarding sensitive data within PHP systems while accommodating dynamic subscription needs and legal access requirements.
