CALL FOR PAPERS 7th Information Hiding Workshop (IH2005) Barcelona, Spain, 6-8 June 2005. Many researchers are interested in hiding information or, conversely, in preventing others from doing so or detecting and extracting the hidden data. Although the protection of digital intellectual property has recently motivated most of the research in this area, there are many other applications of increasing interest to both the academic and business communities. Current research topics include: * anonymous communications, * covert channels in computer systems, * detection of hidden information (steganalysis), * digital forensic, * information hiding aspects of privacy, * steganography, * subliminal channels in cryptographic protocols, * watermarking for protection of intellectual property, * other applications of watermarking. Continuing a series of successful workshops that brought together these closely linked research areas, the 7th International Workshop on Information Hiding will be held in Barcelona, Spain, from Monday 6th June to Wednesday 8th June 2005. Authors can submit their papers online at http://kison.uoc.edu/IH05 where detailed instructions are provided. Important Dates: * paper submissions deadline 17th January 2005, 11:59 PM GMT * notification of acceptance 25th March 2005 * camera-ready copy 10th May 2005 * Workshop 6th-8th June 2005
