The authentication of the smartphone is based on public-key cryptography. This requires that the private key is stored in a secure element or in a trusted execution environment to prevent identity theft. One of the basic requirement of our solution is the independence from third parties like mobile network operators, trusted service managers and handset manufacturers. Therefore, a SIM-based secure element as well as an embedded secure element (i.e. a separate hardware chip on the handset) were not an option and we had to concentrate on the remaining secure element architectures: Host Card Emulation (HCE) and a microSD-based secure element. We show that the HCE approach cannot solve the relay attack under conservative security assumptions and we present and discuss an implementation based on a microSD secure element that still allows the access points to connect to the authorization server upon every access albeit the access points are not connected with it.","PeriodicalId":268141,"journal":{"name":"Proceedings of the 13th International Conference on Advances in Mobile Computing and Multimedia","volume":"486 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124420127","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}

An accurate visual pose estimation is a common and important subtask. To quantitatively evaluate the accuracy, ground truth visual pose datasets are needed. However, the lack of inexpensive and easy benchmarking tool for mobile device based visual poses estimation makes it difficult, if not impossible, to quantitatively evaluate the estimated visual poses. In this paper, a novel and easy-to-implement experimental setup is proposed to generate ground truth visual pose data for handheld tablet-PC. The tablet-PC screen is leveraged to display a calibration pattern every time the on-board camera captures an image. The tablet-PC screen image is captured by another camera and is used to estimate the visual pose of the tablet-PC. An experimental environment is setup for parameter calibration and pose accuracy verification. Extensive experimental results with quantitative analysis demonstrate the accuracy and the generality of our tool.","PeriodicalId":268141,"journal":{"name":"Proceedings of the 13th International Conference on Advances in Mobile Computing and Multimedia","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133000137","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}
