To meet the requirement, our system repeatedly embeds watermark information into the DCT domain with significantly high watermark strength. On the other hand, to keep high image quality, only one DCT coefficient is used for each watermark bit. Thus, the system adds spike noise (or salt-and-pepper noise) to the DCT domain at embedding. The experimental results show that the watermarking system satisfies the IHC criteria ver.3 and achieves high performance in the contest categories called highest tolerance and highest image quality. Specifically, in the highest tolerance category, the embedded watermark information is detected without error even against compression reducing the file size by 0.5 of its original size. On the other hand, in the highest image quality, PSNR is not lower than 41 dB without error against the specified compression ratio, namely, 4%.","PeriodicalId":117756,"journal":{"name":"IWIHC '14","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129967673","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we propose a watermarking scheme robust against the JPEG compression and a clipping attack using the DCT-OFDM based watermarking method. Robustness against the JPEG compression can be achieved by embedding watermark information into the low-frequency components. We employ the QIM method to the DCT-OFDM modulated signal. By embedding a synchronization signal, we attempt to recover the synchronization loss from a clipped image. In a preliminary experiment, we can detect the embedded synchronization signal around a correct synchronization point because the synchronization signal is mainly embedded into the low-frequency components in a spread form. Then, we determine the center among the detected points as the correct synchronization point. We evaluate the performance of our method by computer simulation. It is revealed that our method satisfies the evaluation criteria determined by IHC Committee, while maintaining high image quality.","PeriodicalId":117756,"journal":{"name":"IWIHC '14","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125867684","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At present, many kinds of information hiding algorithms have been designed and applied in real-time VoIP communication, and the most widely used algorithm among them is the LSB (Least Significant Bit) hiding. However, it is difficult to detect the LSB matching steganography in real time. In response to this challenge, this paper raised a structure of system, which is able to capture the VoIP streams on the Internet and detect the real-time subliminal channel in them. We also designed a new steganalysis algorithm for the system which is aimed at the LSB matching steganography algorithm. It used the feature extraction method based on correlation and SVM (Support Vector Machine) classification. The experiment results demonstrated that while the embedding rate was over 50%, the new algorithm raised the accuracy of detecting the LSB matching by about 20% compared with existing algorithms. At the same time, the length of the samples cannot obviously affect the accuracy of the new algorithm; it can detect the information hiding in the samples whose length is only 3s. From this point of view, the new algorithm has good real-time performance.","PeriodicalId":117756,"journal":{"name":"IWIHC '14","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130579714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While histogram shifting offers many advantages, it suffers from relatively low payload, which restricts its applications significantly. In this work, a new reversible data hiding technique based on the modification of the histogram of prediction errors is proposed. The proposed method employs an adaptive strategy to vacate multiple bins as the embedding venues in order to increase the effective payload. The histogram bins are shifted dynamically based on their magnitudes. To maintain high quality for the output image, the distance of shifting is minimized for smaller prediction errors. On the other hand, the distance of shifting is allowed to be larger for larger prediction errors, which are of lower occurrences, to create more space for embedding. The proposed data hiding method is able to reversibly hide larger number of bits into the host image while achieving comparable output image quality when compared to the conventional histogram shifting based methods. The experimental results suggest that, on average, the proposed method is able to embed 0.247bpp into various standard test images, while still maintaining the visual quality at satisfactory level of ~48.9 dB.","PeriodicalId":117756,"journal":{"name":"IWIHC '14","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121638178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
