Information hiding ; 6th International Workshop, IH 2004, Toronto, Canada, May 23-25, 2004, Revised selected papers

All papers were divided into eight sessions: digital media watermarking, steganalysis, digital forensics, steganography, software watermarking, security and privacy, anonymity, and data hiding in unusual content. This year, the workshop included a one-hour rump session that offered an opportunity to the delegates to share their work in progress and other brief but interesting contributions.
