| Summary: | 碩士 === 臺中技術學院 === 資訊工程系碩士班 === 99 === 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.
