We investigate a robust way for image content retrieval based on singular value decomposition to improve the performance of content discrimination. The singular value is used to gain robustness against geometrical variance. To gain higher robustness against other signal processing modifications, an adaptive image thresholding method is used as a preprocessing to SVD. Our experiments are based on 1,000 original images (with different contents) and their 23,000 modified versions, showing improved results of discrimination ability for image contents.","PeriodicalId":272579,"journal":{"name":"2006 International Conference on Intelligent Information Hiding and Multimedia","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127962200","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}

Based on the fact that the statistics of stego signal have a higher jump after sequential embedding, the method effectively indicates the jump in low frequency embedding through adjusting the log likelihood estimator, namely, increasing the power of the standard deviations and introducing the modulating factors, and then develops a new cumulative sum detector. Experiments show that this method still can estimate the secret key in the low frequency embedding even though the message strength is as low as 0.3.","PeriodicalId":272579,"journal":{"name":"2006 International Conference on Intelligent Information Hiding and Multimedia","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121633435","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}

Appropriate alterations, however, should be allowed for some signed documents in practical use because of security requirements other than the integrity of the document. For example, when administrative documents are disclosed, based on the information disclosure law, in such documents, sensitive information, such as privacy information or national secrets is masked in advance. If this procedure is applied using existing digital signature technologies, the original digital signature becomes invalid when part of the document is sanitized. This problem is called the digital document sanitization problem and digital document sanitization schemes have been proposed as a solution to this problem. However, these schemes have disadvantages, such as a lack of flexibility in selecting sanitization blocks or inability to detect illegal sanitization by the sanitizer. In the present paper, we propose a digitally signed document flexible sanitizing scheme (DDFS) that can answer requests for flexible changes in the sanitized sections of a document without compromising security.","PeriodicalId":272579,"journal":{"name":"2006 International Conference on Intelligent Information Hiding and Multimedia","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115861860","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}

The vehicle is guided to follow a path consisting of nodes learned in advance, which include the information of travel distances and turning angles provided by the odometer. A vehicle location method using house corners is proposed to estimate vehicle location which can be used to correct vehicle location, thus preventing mechanic error accumulation in long-distance navigation.

Experimental results validate the effectiveness of the proposed technique with better performance than the popular MD lattice vector quantization proposed by Servetto, Vaishampayan and Sloane (known as SVS technique). Especially the presented technique can effectively alleviate the gap between the central and side distortions in SVS technique.","PeriodicalId":272579,"journal":{"name":"2006 International Conference on Intelligent Information Hiding and Multimedia","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134449986","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}
