摘要

过去几年,信息技术在各个领域都取得了长足进步,许多行业都从纸质媒介过渡到电子媒介。然而,共享电子病历仍是一项长期挑战,尤其是当患者处于紧急情况下时,很难获取和控制他们的医疗信息。以往的研究提出了参与者有限的许可区块链,或允许预先指定的参与者共享紧急医疗信息的机制。然而,许可区块链需要医疗机构的事先参与,而限制共享实体则限制了潜在合作伙伴的数量。这就意味着,如果病人失去知觉且离家很远,比如在国外旅行时,就不可能与当地急救医生共享医疗信息。为了应对这一挑战,我们为全球电子医疗信息系统提出了一个紧急访问控制系统,该系统可使用公共区块链共享,任何人都可以参与。我们提出的系统假定病人佩戴一个具有防篡改和生物识别认证功能的吊坠。在病人失去知觉的情况下,急诊医生可以代表病人进行生物识别,让家庭医生通过使用 Diffie-Hellman (DH)密钥交换协议的安全通道与急诊医生共享健康记录。挂件的生物识别认证功能可防止挂件被盗时的非授权使用,我们还测试了使用公共区块链的区块链费用,证明所提议的系统是实用的。

Emergency Medical Access Control System Based on Public Blockchain

IT has made significant progress in various fields over the past few years, with many industries transitioning from paper-based to electronic media. However, sharing electronic medical records remains a long-term challenge, particularly when patients are in emergency situations, making it difficult to access and control their medical information. Previous studies have proposed permissioned blockchains with limited participants or mechanisms that allow emergency medical information sharing to pre-designated participants. However, permissioned blockchains require prior participation by medical institutions, and limiting sharing entities restricts the number of potential partners. This means that sharing medical information with local emergency doctors becomes impossible if a patient is unconscious and far away from home, such as when traveling abroad. To tackle this challenge, we propose an emergency access control system for a global electronic medical information system that can be shared using a public blockchain, allowing anyone to participate. Our proposed system assumes that the patient wears a pendant with tamper-proof and biometric authentication capabilities. In the event of unconsciousness, emergency doctors can perform biometrics on behalf of the patient, allowing the family doctor to share health records with the emergency doctor through a secure channel that uses the Diffie-Hellman (DH) key exchange protocol. The pendant’s biometric authentication function prevents unauthorized use if it is stolen, and we have tested the blockchain’s fee for using the public blockchain, demonstrating that the proposed system is practical.

期刊介绍: Journal of Medical Systems provides a forum for the presentation and discussion of the increasingly extensive applications of new systems techniques and methods in hospital clinic and physician''s office administration; pathology radiology and pharmaceutical delivery systems; medical records storage and retrieval; and ancillary patient-support systems. The journal publishes informative articles essays and studies across the entire scale of medical systems from large hospital programs to novel small-scale medical services. Education is an integral part of this amalgamation of sciences and selected articles are published in this area. Since existing medical systems are constantly being modified to fit particular circumstances and to solve specific problems the journal includes a special section devoted to status reports on current installations.
