以往電子病歷是上傳生理資訊到雲端，讓醫護人員更容易存取和管理資料，或者有效整合病歷。這些資料往往只提供醫護人員檢視，並且著重於管理電子病歷和傳輸資料為主。本論文提出於雲端環境執行且以病友為中心的個人健康紀錄PHR(Personal Health Record)的架構。由病友主動管理自身健康資訊，如就診的資料、健康報告，生理資訊…等，明確了解自己的健康狀況，並且採取更積極的態度維持健康。從病友的角度思考，由病友決定資料的開放權限，以及其使用期限。在雲端的環境中存放資料有助於降低成本、資訊分享，卻也伴隨潛在的資訊安全的威脅。因此本論文提出適用於多重使用者(如照護人員、病人本身，家屬…)的雲端環境安全傳送機制，使用者藉由本論文提出的傳送機制與伺服器端溝通，獲得欲取得的資料，並同時保障使用者以及伺服器端的隱私與安全性，同時也能提供多重使用者傳輸資料的過程中確保資訊的安全性。 Electronic medical records containing vital information were uploaded to the cloud, allowing medical crews more easy access and management of data and integration of medical records. Such data system provides relevant information to medical personnel and facilitates and stress on electronic medical record management and data transmission.A structure of cloud-based and patient-centered personal health record (PHR) is proposed in this study. Which enables patients to automatically manage their health information, such as appointment date with doctor, health reports, and a throughout understanding of their own health conditions, and a positive attitudes to maintain the health. The patients decides for themselves who has access to their records over a specific span of time specified by the patients.Storing data in a cloud environment could reduce costs and enhance the share of information, but the potential threat of information security should be taken into consideration. A cloud-based secure transmission mechanism suitable for multiple users (like nurse aides, patients, and family members) is proposed in this study.
