This paper focuses on two less common but increasingly used types of attack: crop attacks and merge attacks. Crop attack crops a fragment of the original map and uses the fragment as a new map. When the new map is much smaller than the original map, it is called massive cropping. Merge attack merges maps from various sources together to form a new map. Conventional watermarking techniques fail against these attacks either because they require global information from the whole map or they must add too many local watermarks and affect the usability of the maps. This paper proposes a novel quad-tree based blind watermarking scheme that partitions the original map according to the quad-tree and plants just one single bit in each sub-region of the map. The approach achieves almost 100% detection accuracy for moderate crop and merge attacks, and over 80% accuracy with more than 95% of the original map cropped and removed. Furthermore, the method introduces very little distortion to the original map: to effectively protect a 23.5MB Minneapolis-St.Paul map against crop and merge as well as other common attacks, only 423 bits or 53 bytes of watermark is required.","PeriodicalId":243756,"journal":{"name":"Information Hiding and Multimedia Security Workshop","volume":"133 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121301192","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}

A traitor should not be able to deny his responsibility of a copyright violation caused by him in such protocols. This feature is identified as non-repudiation in the literature. An efficient approach taken is through secure embedding of watermarks in an encrypted domain by using dither modulation and homomorphic encryption. To support non-repudiation along with collusion resistance, one needs an asymmetric collusion resistant fingerprinting code that is compatible with the watermarking technique. The design of such codes has not yet studied thoroughly with an exception of a recent work by Charpentier et. al. in [4].\u0000 In this paper, we propose an asymmetric binary fingerprinting code based on Boneh-Shaw code. When applied to the secure embedding of watermarks, we show that our code outperforms the code introduced by [4]: (i) we achieve constant communication round, (ii) we do not require any oblivious transfer protocol and (iii) we do not require any public Write Once Read Many (WORM) directory.","PeriodicalId":243756,"journal":{"name":"Information Hiding and Multimedia Security Workshop","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130444861","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 place 40 prints from different subjects on hard disk platters and capture them from three different indoor locations every week over 1.5 years, acquiring high-resolution time series (10 μm and 20 μm). In contrast to prior findings from Popa et al. (using glass substrates) we show that the ridge thickness of our very precise images does not significantly decrease over time (test goal 1). We furthermore show that pores exhibit a significant loss in contrast and contour, which might lead to the impression of becoming bigger and fewer (test goal 2). Computing the contrast based Binary Pixel aging feature (test goal 3), we observe very characteristic results, leading to the conclusion that the dominant aging property seems to be an overall loss of image contrast rather than a specific change of ridge thickness or pore size. Comparing our findings between three different indoor locations (test goal 4) and discussing them from a police point of view, we conclude that sweat composition, environmental influences and scan parameters have a significant impact on fingerprints long-term aging.","PeriodicalId":243756,"journal":{"name":"Information Hiding and Multimedia Security Workshop","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115445314","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}
