By Jessica Fridrich (auth.), Yun Qing Shi, Hyoung-Joong Kim, Fernando Perez-Gonzalez (eds.)

This ebook constitutes the completely refereed post-conference complaints of the tenth overseas Workshop on Digital-forensics and Watermarking (IWDW 2011) held in Atlantic urban, NJ, united states, in the course of October 23-26, 2011. The 37 revised complete papers provided have been conscientiously chosen from fifty nine submissions. convention papers are equipped in 6 technical periods, overlaying the themes of steganography and steganalysis, watermarking, visible cryptography, forensics, anti-forensics, fingerprinting, privateness and security.

Example text

2b. (d) Modifications between the cover image and the EALSBMR stego image. (e) The re-arranged version of Fig. 2d. embedding process can be modeled as the addition of additive noise (stegonoise) to the cover image. The more pixels get modified, the more the power of the additive stegonoise is added to the cover image. In this paper, The power of the stegonoise is referred to as the intensity factor of the embedding process applied to a pixel series. It can be concluded that the intensity factor in {xi } should be larger than that in {xi+1 }.

However, in the current stage, our method can not attack EALSBMR with Bz > 1. This is because that the reliability of the proposed method depends on the correct partition of embedding units with two consecutive pixels, while the rotation operation of EALSBMR with Bz > 1 prevents us to do so. How to construct efficient detector for EALSBMR with Bz > 1, it is our work for further study. Acknowledgment. The author would like to thank Prof. Yun Q. Shi at New Jersey Institute of Technology, New Jersey, USA, for providing us the test image set.
