| Abstract: | 近年來，隨著網路資訊的普及和個人隱私意識的提升，個人識別資料的分享和保護已經變成重要網路研究議題之ㄧ。資料存放在雲端環境上，因不同資料來源之間結構上的差異，我們將會面臨到如何建立PII的分享和保護準則，以確保滿足資料擁有者的隱私偏好。
本研究使用雲端運算做為多個資料源執行資料交換的環境，其好處在於擁有大量的網路存放空間、大幅降低了資料管理成本。舉例來說，我們可在雲端環境上存放大量的醫療資料，當使用者欲查詢不同來源的醫療資料時，可透過資料交換的方式從單一入口取得，不需兩端分別進行查詢，並利用雜湊函數的方式來處理個人資料匿名性的辨識，主要是在不揭露個人資料的狀況下，仍然可以判斷資料是否為同一筆資料。
另外，由於本研究以個人隱私資料做為研究之情境，所以在隱私保護上會以存取控管規範(Access Control Policy，ACP)、資料處理規範(Data Handling Policy，DHP)和資料釋放規範(Data Release Policy，DRP)，三種規範來說明資料保護、資料交換和資料揭露的過程。
最後，本研究主要是使用具有語意化技術本體論和規則的知識表達來解決跨資料源的資料交換，除了理論塑模之外並且利用兩家醫院的情境來加以展示。
Personal Identifiable Information (PII) sharing and protection have become one of the most important research issues for the Internet, especially for cloud computing infrastructure because of its widespread services. The challenge of sharing structured PII data in the cloud is to address the structure differences between data sources. In addition, we face the problem for how to establish the PII sharing and protection principles to ensure that its disclosure criteria are satisfied with the data owners` privacy policies.
In this study, we use cloud computing simulated environment as a multiple data sources exchange platform because of its spacious and cost-effective reasons. For example, we can outsource tremendous amount of electronic health record (EHR) administration services in the cloud without too much cost. Besides, data exchange provides a single point of data access instead of having accessed in a separate entry. We apply hash function of de-identifiable partial PII to enable record linkage services between data sources for data exchange without losing data owners` privacy.
Three types of privacy protection policies are proposed to achieve the data exchange and protection objectives in the multiple sources data cloud. They are Access Control Policy (ACP), Data Handling Policy (DHP), and Data Releasing Policy (DRP). These policies are represented as OWL-based ontologies and enforced as Logic-Program (LP)-based rules. We demonstrate the privacy protection policy concepts for medical record exchange between two hospitals. |
