摘要

網際網路日益發達，主要是其具有匿名和自由的特性，並帶動多元化的網路應用於服務及產業發展，使用者可以獲取更多、更便利的資訊。然而也產生許多不當的網路行為，利用隱匿與偽造身分的方式進行犯罪行為。為了安全，認證真實身分，實施網路實名制避免隱匿與偽造身分是重要的一環，但對於網路的匿名文化以及個人隱私權，網路實名制衍生了許多爭議。為了兼顧安全與方便，本研究植基於隱式憑證的概念提出「基於隱式憑證之可追蹤記名協定」，目的在折衷實名制和匿名制，結合憑證及數位簽章機制，在原本行為中規範身分認證的行為，提高偽冒身分門檻外，也可適度隱藏使用者真實身分實現匿名性，出現糾紛的時候，可透過特定的方式揭示使用者的身分資料。

Internet has already becomes part of most human’s life rapidly.Deal to the characteristic of anonymity and flexibility, Internet has tremendous potential and a lot to offer in terms of services. It is also an indispensable business tool, which all kind of the information can be shared world-wide.Internet makes positive social improvement.There are also growing concerns about media security, privacy and other related internet crime which the users are taking advantage of the anonymity of the Internet. In order to providea safe and convenient Internet environment, our research proposed the idea of implicit certificates which aims to strike a balance between Real-Identity and Anonymity by combining digital signatures and digital certificates mechanism.Therefore, the possibility of faking identity will be significantly deceased; meanwhile, it could keep certain degree of anonymity. The user’s identity could be reveal using specific procedures when conflicts arise.
