Using Healthcare Authority and Patient Blockchains to Develop a Tamper-Proof Record Tracking System

Abstract

Blockchain technology combines the openness of the Internet with the security of cryptography to provide a way to verify key information and to establish a trust in applications such as peer-to-peer payment services. Blockchain can be used to track the healthcare transactions and can ensure authorized access to patient records and compliance with the health information protection laws. In this paper, a dual blockchain model for the healthcare sector is proposed. The model combines healthcare authority blockchains and private patient blockchains for a tamperproof permission tracking system which ensures increased security and privacy while improving record and permission redundancy. The proposed model and its possible implementation are discussed in the context of Canadian healthcare privacy legislation in Alberta.
