We design and implement a browser based tool that provides detailed measurements of online display ads, and develop analysis techniques to characterize the contextual, behavioral and re-marketing based targeting mechanisms used by advertisers. Our analysis is based on a large dataset consisting of measurements from 103K webpages and 139K display ads. Our results show that advertisers frequently target users based on their online interests; almost half of the ad categories employ behavioral targeting. Ads related to Insurance, Real Estate and Travel and Tourism make extensive use of behavioral targeting. Furthermore, up to 65% of ad categories received by users are behaviorally targeted. Finally, our analysis of re-marketing shows that it is adopted by a wide range of websites and the most commonly targeted re-marketing based ads are from the Travel and Tourism and Shopping categories.","PeriodicalId":203847,"journal":{"name":"Proceedings of the Twelfth ACM Workshop on Hot Topics in Networks","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116008164","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}

However, in this paper, we report a newly discovered class of attacks on MPTCP that may jeopardize and hamper its wide-scale adoption. The attacks stem from the interdependence between the multiple subflows in an MPTCP connection. MPTCP congestion control algorithms are designed to achieve resource pooling and fairness with single-path TCP users at shared bottlenecks. Therefore, multiple MPTCP subflows are inherently coupled with each other, resulting in potential side-channels that can be exploited to infer cross-path properties. In particular, an ISP monitoring one or more paths used by an MPTCP connection can infer sensitive and proprietary information (e.g., level of network congestion, end-to-end TCP throughput, packet loss, network delay) about its competitors. Since the side-channel information enabled by the coupling among the subflows in an MPTCP connection results directly from the design goals of MPTCP congestion control algorithms, it is not obvious how to circumvent this attack easily. We believe our findings provide insights that can be used to guide future security-related research on MPTCP and other similar multipath extensions.","PeriodicalId":203847,"journal":{"name":"Proceedings of the Twelfth ACM Workshop on Hot Topics in Networks","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116241636","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}

We propose Crypto-Book, an extension to existing digital identity infrastructures that offers privacy-preserving, digital identities through the use of public key cryptography and ring signatures. Crypto-Book builds a privacy-preserving cryptographic layer atop existing social network identities, via third-party key servers that convert social network identities into public/private key-pairs on demand. Using linkable ring signatures, these key-pairs along with the public keys of other identities create unique pseudonyms untraceable back to the owner yet can resist anonymous abuse. Our proof-of-concept implementation of Crypto-Book creates public/private key pairs for Facebook users, and includes a private key pickup protocol based on E-mail. We present Black Box, a case study application that uses Crypto-Book for accountable anonymous whistle-blowing. Black Box allows users to sign files deniably using ring signatures, using a list of arbitrary Facebook users -- who need not consent or even be aware of this use -- as an explicit anonymity set.","PeriodicalId":203847,"journal":{"name":"Proceedings of the Twelfth ACM Workshop on Hot Topics in Networks","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128625889","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}
