Proceedings of the 2020 ACM Workshop on Information Hiding and Multimedia Security

It is our great pleasure to welcome you to the 3rd ACM Information Hiding and Multimedia Security Workshop -- IH&MMSec'15 in Portland, Oregon. Portland is also where the 2nd Information Hiding Workshop (IHW) was held 17 years ago. Over these years, the field has developed tremendously by the relentless effort of many scientists and researchers all over the globe, and many of their research results have been implemented into useful products. In response to our call for papers, 45 excellent papers were submitted from the United States, Canada, Europe, Asia, and Malaysia. The best 20 of these papers were accepted (44% acceptance rate) and assembled into a strong technical program. The accepted papers cover the fields of steganography and steganalysis in digital media, digital watermarking of 3D objects, covert channels, watermarking and fingerprinting codes, digital forensics, biometric and authentication, encryption, and privacy. The technical program also features two invited keynote speakers. The first presentation is about the implications of cyber warfare, and it is given by Mr. David Aucsmith, from Aucsmith Consulting LLC. The second presentation is about the privacy of the Internet of Things, and it is given by Dr. Richard Chow, from Intel Corporation. As usual, the workshop is structured into three days with the afternoon of the second day devoted to a social event. The social event is designed to promote discussions and to help establish relationships for future collaboration among participants. Also, at the end of the first day, an hour is reserved for a rump session during which the participants are encouraged to share their work in progress, discuss unpublished results, demo new products, and make relevant announcements. A great team effort put together the technical program. The Program Committee assisted by 16 external reviewers provided timely and high-quality reviews. A double-blind review process was used to ensure fairness. Each paper was carefully read and appraised by at least three reviewers. To let the Program Chairs select the best quality and relevant work, papers with conflicting reviews were discussed at length. We expect the selected papers to be of wide interest to researchers working in the field and to participants from industry and from government institutions. We thank all participants for their help in putting together this great program.
