【 摘 要 】

Over the past several years, many healthcare applications have been developed to enhance
the healthcare industry. Recent advancements in information technology and blockchain technology
have revolutionized electronic healthcare research and industry. The innovation of miniaturized
healthcare sensors for monitoring patient vital signs has improved and secured the human healthcare
system. The increase in portable health devices has enhanced the quality of health-monitoring
status both at an activity/fitness level for self-health tracking and at a medical level, providing more
data to clinicians with potential for earlier diagnosis and guidance of treatment. When sharing
personal medical information, data security and comfort are essential requirements for interaction
with and collection of electronic medical records. However, it is hard for current systems to meet
these requirements because they have inconsistent security policies and access control structures.
The new solutions should be directed towards improving data access, and should be managed by
the government in terms of privacy and security requirements to ensure the reliability of data for
medical purposes. Blockchain paves the way for a revolution in the traditional pharmaceutical
industry and benefits from unique features such as privacy and transparency of data. In this paper,
we propose a novel platform for monitoring patient vital signs using smart contracts based on
blockchain. The proposed system is designed and developed using hyperledger fabric, which is
an enterprise-distributed ledger framework for developing blockchain-based applications. This
approach provides several benefits to the patients, such as an extensive, immutable history log, and
global access to medical information from anywhere at any time. The Libelium e-Health toolkit
is used to acquire physiological data. The performance of the designed and developed system is
evaluated in terms of transaction per second, transaction latency, and resource utilization using
a standard benchmark tool known as Hyperledger Caliper. It is found that the proposed system
outperforms the traditional health care system for monitoring patient data.
