Nowadays, e-books gradually replace the traditional paper books. People become accustomed to read e-books, increasingly. Via digital technology and Internet, authors can distribute knowledge and information to readers through e-books more efficient and convenient than paper books. One of the e-books' features is the contents of them being easy to copy illegally. Till to now, there is no effective technology to prevent such an illegal action. Thus, illegally copying is a real problem of e-book technology. However, one can prove that she/he has ownership to the copy of an e-book. Such an e-book copy is a legal one. Owner needs to 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.
