應用具不可追蹤性的RFID於住院病人配藥安全之研究

A study of applying untraceable RFID for inpatient medication safety

在台灣，2010年醫療疏失事件中，藥物疏失事件位居第一，嚴重危害國人的醫療安全。會導致藥物疏失事件因素很多，例如藥名相似、配藥人員的疏失、藥物不良、⋯等，如何改善醫療疏失事件，目前已成醫療安全重要的課題。其中，如何將科技導入醫療體系中，以降低發生藥物失誤事件的機率，已成有效解決醫療誤置之重要選項，例如藥物與病人都擁有各自的RFID標籤，護士利用RFID的識別特性可以幫助識別病人身份與其藥物，以減少醫療錯誤的發生。在本論文中，我們建立安全用藥的RFID標籤雙向驗證機制，提供不可追蹤性並抵擋無線RFID標籤資訊外溢及其他攻擊行為，提供用藥資訊之不可否認性等，來提高用藥之準確性與安全性以保障病人權益。

In Taiwan, medication errors which account for the major medical negligence incident in 2010 would seriously endanger people's health care safety. There are many factors that induce the medication errors, such as the similar names among the drugs, the negligent dispensation of drugs, adverse drug problems, and so forth. How to apply information technology to improve medical malpractice has become an important research topic. To build RFID technology into the overall health behavior in order to reduce the occurrence of drug blunders or negligence of the dispensing staff has become a very important option for the medical malpractice. Examples are, drugs and patients have their own RFID labels, nurse medical practices is certified by smart-card, and safe medical behavior is ensured and responded. In this paper, based on RFID's identification of patients' identity and associated drugs, we further establish a two-way authentication mechanism and untraceable messages among the RFID tags, and thus, withstand malicious attacks. The dispensing process is undeniable and the responsibility is therefore established. All this can protect patients' rights and improve the environment and quality of the patient's medical.
