The ease of capturing, manipulating, distributing, and consuming digital media (e.g. images, audio, video, graphics, and text) has motivated new applications and raised a number of important security challenges to the forefront. These applications and challenges have prompted significant research and development activities in the areas of digital watermarking, steganography, data hiding, forensics, media identification, and encryption to protect the authenticity, security, and ownership of media objects. Research results in these areas have translated into new paradigms and applications to monetize media objects without violating their ownership rights. The Media Watermarking, Security, and Forensics conference is a premier destination for disseminating high-quality, cutting-edge research in these areas. The conference provides an excellent venue for researchers and practitioners to present their innovative work as well as to keep abreast with the latest developments in watermarking, security, and forensics. The technical program will also be complemented by keynote talks, panel sessions, and short demos involving both academic and industrial researchers/ practitioners. This strong focus on how research results are applied in practice by the industry gives the conference its unique flavor.
