Authorship Proof for Textual Document

J. Wu and D. R. Stinson

Abstract

In this paper, we investigate the problem of how to prove the authorship of textual documents. First we define the basic functionalities of an authorship proof scheme (APS) based on natural language watermarking, and identify two essential security requirements for an APS to be secure against various attacks. We review existing natural language watermarking schemes, and we propose two new schemes with improved security.
