A Blockchain-Based Secure Inter-Hospital EMR Sharing System

Abstract: In recent years, blockchain-related technologies and applications have gradually emerged. Blockchain technology is essentially a decentralized database maintained by the collective, and it is now widely applied in various fields. At the same time, with the growth of medical technology, medical information is becoming increasingly important in terms of patient identity background, medical payment records, and medical history. Medical information can be the most private information about a person, but due to iss… Show more

“…The proposed strategy ensures that personal/critical user data is kept confidential, securely processed, and is exposed to the stakeholders on a need-to-know basis as per user-defined Access Control List (ACL) rules embedded in smart contracts. Chen et al [ 19 ] proposed a Blockchain-based secure inter-hospital system, which was used to share electronic medical records (EMRs) between different hospitals. Their proposed scheme is immune to data manipulation and data leak.…”

“…(4) Non-repudiation [5,6,11,12]: The data source cannot arbitrarily reject the behavior and content of the message. (5) Message irreversibility [13][14][15][16][17][18]: The corresponding plaintext cannot be traced back from the encrypted message. (6) Resist counterfeiting attacks [14][15][16][17][18][19]: By verifying the public and private keys, the correctness of the message source can be ensured.…”
