Nowadays, mobile devices are the most important components in human life. With the help of various apps, we can interact with other people, play games to kill time, or perform online shopping activities. However, despite the convenience of mobile devices, most cross-institutional electronic medical record (EMR) sharing still needs some written forms and waiting time for application. Although some existing blockchain-based data exchange architectures have been proposed, most frequently used mobile devices have never been considered. This study integrates the mobile devices to develop a blockchain-based patient-centric EMR sharing system considering data security, data integrity, and patient privacy. Under the patient’s consent, the proposed system can support selective data sharing between different institutions through blockchain in real-time. Patients have the complete right to disclose what their EMR can share. Further, using mobile devices to scan the QR code provided by the doctor, patients can easily employ this public key infrastructure to achieve enhanced data security. The proposed system provides necessary functionalities (authentication, integrity, and access control) for EMR data exchange. It shows how mobile features (camera, notification, bio-authentication) can be favorable to fulfill patient satisfaction.
