The 13th IWDW, International Workshop on Digital-forensics and Watermarking (IWDW 2014) is a premier forum for researchers and practitioners working on novel research, development and applications of digital watermarking and forensics techniques for multimedia security. This year, IWDW 2014 is hosted by National Dong Hwa University (NDHU) and National Taipei College of Business in Taiwan on October 1-4, 2014.We invite submissions of high-quality original research papers. Each submitted paper will be reviewed by at least two reviewers. Two prizes are to be awarded for the best paper and the best student paper, respectively. The proceedings of IWDW 2014 will be published on the Lecture Notes in Computer Science (LNCS) by Springer. (Special issues based on IWDW 2014 are to be published in Journal of Computers (EI indexed) and International Journal of Network Security (EI indexed).) The topics include, but are not limited to:

　* Mathematical modeling of embedding and detection
　* Information theoretic, stochastic aspects of data hiding
　* Security issues, including attacks and counter-attacks
　* Combination of data hiding and cryptography
　* Optimum watermark detection and reliable recovery
　* Copyright protection, DRM, and forensic watermarking
　* Large-scale experimental tests and benchmarking
　* New statistical and perceptual models of multimedia content
　* Estimation of watermark capacity
　* Reversible data hiding
　* Data hiding in special media
　* Data hiding and authentication
　* Steganography and steganalysis
　* Channel coding techniques for watermarking
　* Digital multimedia forensics & anti-forensics
　* Visual cryptography and secret image sharing
