摘要

本論文提出基於Ubiquitous healthcare(U-healthcare)觀念之生理訊號監測系統。我們將電子血壓計之信號藉由藍芽技術傳送至PDA後，再以適當方式回傳至後端伺服器。為了使受照護者的隱私及確保量測的生理資訊受到保護，本論文利用了DES及RSA之聯合加密演算法，分別針對受照護者資料以及DES演算法所設定之金鑰加密，使加解密速度及資訊安全達到適當的妥協。相對於過去護理人員以抄寫的方式記錄病人的生理量測的數據，回到護理站再以手動輸入至電腦做記錄。本論文所提出的方法將可有效改善其量測生理訊號之效率、正確性及安全性。

In this paper, the authors propose a measuring system of physiological signals based on the concepts of Ubiquitous healthcare. By using the Bluetooth technology and the physiological signals can be transferred to a server appropriately via personal digital assistant (PDA). In order to protect the patients’ privacy and preserve the security of the large number of measured signals, we use DES and RSA joint algorithms to encrypt all the data of the cared people and the key of DES algorithm, respectively. It provides the well-compromise between the speed of encryption/decryption and the information security. In contrast to the conventional nursing, that is, the nurses record the physiological data via hand write and input the data to a computer when they go back to the nursing station. Our proposed approach can effectively improve the efficiency, correctness, and security.
