面對高齡社會的來臨，利用資訊科技來強化高齡者照護之需求日增，許多健康照護相關之系統平台因應而生，以期針對高齡者提高更安全、尊嚴、舒適與便利的生活與照護品質。由於健康照護系統或平台涉及個人隱私且機密資訊，例如：個人居家環境、生理資訊等，因此電腦犯罪與隱私權侵犯所引發的資訊安全問題，將嚴重侵犯個人隱私，而且會影響高齡者接受照護資訊系統之意願。本文將考量健康照護系統之安全性、資訊交換的機密性以及個人隱私保護等，提出一個具安全與隱私保護之即時互動照護平台，讓家屬、高齡者以及照護者可以在一個安全且具隱私保護的即時互動平台上安心溝通，以提供高度的資訊安全保障。

Considering the demand of improving elders' healthcare by adopting emerging technologies, many healthcare systems are proposed recently. Much sensitive personal information will be transmitted on such systems. If the systems are compromised or the system managers are corrupted, it will reveal elders' privacy. This paper will first design two security mechanisms suitable for improve the security and the privacy of the interactive healthcare platform. A real-time interactive healthcare platform preserving security and privacy is also implemented using the proposed mechanisms. This platform allows carers, family members, and elders to communicate with each other in a secure and privacy way. No sensitive personal information will be compromised or revealed.
