ACM Workshop on Digital Rights Management (ACM DRM 2011) Chicago, USA, October 21, 2011 http://drm11.cased.de/ held in conjunction with ACM CCS 2011 The ACM Workshop on Digital Rights Management is an international forum that serves as an interdisplinary bridge between areas that can be applied to solving the problem of Intellectual Property protection of digital content. These include: cryptography, software and computer systems design, trusted computing, information and signal processing, intellectual property law, policy-making, as well as business analysis and economics. Its purpose is to bring together researchers from the above fields for a full day of formal talks and informal discussions, covering new results that will spur new investigations regarding the foundations and practices of DRM. This year's workshop, the 11th in the series, continues this tradition. Topics of interest include but are not limited to: - Content identification including digital watermarking and fingerprinting - Anonymous publishing - Privacy and DRM - Architectures for DRM systems - Security issues, including authorization - Supporting cryptographic technology including traitor tracing, broadcast encryption - Software tamper resistance, obfuscation, plagiarism detection - Trusted computing, attestation, hardware support for DRM - Usability aspects of DRM systems - Attacks against DRM systems - Web services related to DRM systems - Implementations and case studies - Regulatory authority for DRM, interoperability - IP protection - Business models for online content distribution, risk management - Copyright-law issues, including but not limited to fair use - Digital policy management - DRM and consumer rights, labeling and competition law Important dates: - Submission deadline: June 27, 2011 - Notification of acceptance: August 5, 2011 - Camera-ready copy for proceedings: August 25, 2011 - Registration deadline for authors: August 25, 2011 - Conference: October 21, 2011
