植基於 ID-PKC 電子書數位所有權
An ID-PKC-Based Scheme for Digital Ownerships of e-books
摘要
現今電子書已經逐步的取代了傳統的紙本書籍。人們已經逐漸的習慣閱讀電子書。在透過數位科技和網際網路幫助下，電子書可以讓許多作者以快速、方便、有效率的方式分享其知識和資訊。但電子書有一個嚴重缺點就是非常容易被拷貝。雖然有一個數位版權管理(DRM)的計畫被提出來。該計畫規定需要使用特別的軟、硬體設備才能讀取電子書或數位多媒體並對其做存取控制。但DRM依然無法解決數位檔案容易被複製盜版的問題，時至今日仍沒有一個有效的方式來防止這類型的非法行為。所以電子書的實際應用裡，非法複製一直都是存在著的困難問題。在這種情形下，電子書要保護的重點應該是電子書的所有權，而不是在於電子書本身的內容。換言之電子書擁有者需要有一個方法可以向其他人證明其的擁有的電子書檔案是合法。所以在本篇論文所提出的計畫裡，使用每個電子書擁有者的個人身份辨識碼來產生，電子書的數位所有權並結合使用公開金鑰的方式來證明該電子書檔案擁有者數位所有權是合法的，該計畫裡也包含著數位所有權的轉換方式，可用於租借轉讓。本論文產生數位所有權的方式是使用一種名為變色龍雜湊函數的方法，我們會證明該方法產生數位所有權和提出的計畫是安全和有效的。
並列摘要
Nowadays, e-books gradually replace the traditional paper books. Peoples become accustomed to read e-books, increasingly. Via digital technology and Internet, authors can distribute knowledge and information to readers through e-books more efficiently and conveniently than paper books. However, the e-book has a severely defect that it can be easily copied. Although a digital right management scheme is proposed that the scheme is an access control method by a special software and hardware. But the scheme cannot effectively remedy the problem of illegal copy. Till now, there is no effective technology to prevent such an illegal action. Thus, illegally copying is a hard problem of e-book application. In this situation, the e-book protection must focus on the e-book ownership, not the e-book content. One can prove that she/he has ownership to the copy of an e-book. Such an e-book copy is a legal one. In other words, e-book owner needs a method that can prove the ownerships of her/his e-book copy to others. Therefore, the presented paper proposes an ID-PKC-based scheme to prove the digital ownership to a legitimate copy of e-book. The proposed scheme supports the ownership transfer of an e-book copy. Based on the properties of chameleon-hash, we can prove the proposed scheme is secure and efficient.
