植基於區塊鏈之醫療服務品質匿名評價評論系統

ANONYMOUS EVALUATION AND COMMENT SYSTEM FOR QUALITY OF MEDICAL SERVICE BASED ON BLOCKCHAIN

近來區塊鏈的出現帶起了一波的應用風潮，非常多的學者及研究人員紛紛提出了植基於區塊鏈之電子病歷與醫療數據的交換架構，這些設計的概念與所建置之系統極大程度地達到醫療資訊安全地分享的目標。事實上，除了醫療資訊之外，許多的患者也同樣非常在乎醫療人員專業能力及服務品質資訊的分享，因為這也是尋求醫療專業人士的病人可以參考的重要訊息之一。因此，植基於現有的電子病歷及醫療資訊交換區塊鏈之上，我們設計嵌入一套附屬的匿名醫療服務品質評價評論系統，這系統只允許受過醫生的門診、急診和住院服務的患者能提出匿名之評價或評論，但是如果醫療人員認為自身面臨惡意的評價或評論攻擊的話，也可以透過法院（公正的第三方）經由適當的機制將攻擊者糾舉出來，經由系統效能與安全性分析之後，我們也確認此架構的高效用度與安全性。

Recently, the emergence of blockchain has brought about a wave of applications. Many scholars and researchers have put forward an exchange structure of electronic medical record and medical data based on the blockchain technology. These design concepts and built systems have reached a great extent of the safe sharing of medical information. In fact, in addition to the electronic medical information, many patients also strongly care for the sharing of expertise and quality of medical service providers. This is because it is one of the important references while patients seek suitable medical professionals. Therefore, on the basis of the blockchain of existing electronic medical records and information exchange, we have designed and embedded an anonymous medical quality of service evaluation & comment system, which allows only outpatients, emergency patients and inpatients who have been served by a doctor to submit anonymous evaluations or comments. However, if the medical personnel think that he/she faces malicious evaluations or comments, the attacker can be rectified through court and the appropriate tracking mechanisms. After the system performance and security analysis is conducted, we confirm that the efficiency and security of this architecture is excellent.
