Abstract EN
Personal health record system (PHR system) stores health-related information of an individual.
PHR system allows the data owner to manage and share his/her data with selected individuals.
The originality or tamper resistance feature is crucial for PHR system because of the irreversible consequence of incorrect information.
Blockchain technology becomes a potential solution due to its immutability and irreversibility properties.
Unfortunately, some technical impediments such as limited storage, privacy concern, consent irrevocability, inefficient performance, and energy consumption exist.
This work aims to handle these blockchain drawbacks and propose a blockchain-based PHR model.
The proposed model is built using the blockchain technology to support a tamper resistance feature.
Proxy reencryption and other cryptographic techniques are employed to preserve privacy.
Features of the proposed model include fine-grained and flexible access control, revocability of consent, auditability, and tamper resistance.
A detailed security analysis shows that the proposed model is provably secure for privacy and tamper resistance.
The performance analysis shows that the proposed model achieves a better overall performance compared with the existing approach in the literature.
Thus the proposed model is more suitable for the PHR system usage.
