Abstract

In this paper, we investigate the problem of how to prove the authorship of textual documents. We propose to use natural language watermarks to solve the problem. We identify two essential requirements for an authorship proof scheme (APS) to be secure against watermark erasing attacks. We evaluate the security of existing natural language watermarking schemes, and we propose two new APS with improved security.
