Tremendous effort, time and money have been spent to detect fraud where there are studies done on creating personalized model for each credit card holder to identify fraud. These studies claimed that each card holder carries different spending behavior which necessitates personalized model. However, to the best of our knowledge, there has not been any study conducted to verify this hypothesis. Hence, in this paper, we investigate the effectiveness of personalized models compared to the aggregated models in identify fraud for different individuals. For this purpose, we have collected some actual transactions and some other data through an online questionnaire. We have then constructed personalized and aggregated models. The performance of these models is evaluated using test data set to compare their accuracy in identifying fraud for different individuals. To our surprise, the experimental results show that aggregated models outperforms personalized models. Besides, we have also compared the performance of the random forest and Naïve Bayes in creating the models for fraud detection. Generally, random forest performs better than the Naïve Bayes for the aggregated model while Naïve Bayes performs better in the personalized models.","PeriodicalId":260515,"journal":{"name":"2012 Third FTRA International Conference on Mobile, Ubiquitous, and Intelligent Computing","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125882652","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}

WMSNs characteristics such as limited resources and restricted power in addition to multimedia specifications such as high-bandwidth and real-time constraints have made programming for such networks complicated. To provide a high-level interface for programmers and end users a middleware is needed between OS layer and applications to hide low-level details. None of the existing middle-wares has focused especially on multimedia ones. In this article, we propose a middleware named SAWM based on network architecture suitable for WMSNs. This Network architecture is a three layered one that is composed of infra-red sensors, visual sensors and smart cameras. SAWM is a service-oriented agent-based middleware. It looks at the network as a service provider composed of several services that programmers just need to put needed services in an order and create a relation between them to make an execution flow. As a result code updates can be easily done and less memory is used for keeping programming codes. The proposed model is evaluated using a case study trying to commit a monitoring task.","PeriodicalId":260515,"journal":{"name":"2012 Third FTRA International Conference on Mobile, Ubiquitous, and Intelligent Computing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128770356","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}

Youssef","doi":"10.1109/MUSIC.2012.20","DOIUrl":"https://doi.org/10.1109/MUSIC.2012.20","url":null,"abstract":"Traditional e-voting systems replace the paper-based process with an electronic one at official voting locations. Remote e-voting, where the voter can vote from any location, increases both participation rates in the elections and the user's satisfaction as it eases the voting process and saves time. However, having a remote e-voting system increases the security vulnerabilities. Those vulnerabilities include harder user authentication, possibility of malicious software on the user's devices, network malicious nodes, coercion, and vote-selling. We introduce UVote as a ubiquitous, convenient, verifiable, and incoercible democratic e-voting system. UVote works as a front-end to many of the current traditional e-voting systems, providing the user with a convenient voting solution with guarantees on security, achieving the best of both worlds. The key design principal in UVote is redundancy at system architecture different components, including voting devices, vote verification, and allowing voting multiple times. We present the UVote architecture and how it leverages redundancy to achieve its goals. We also analyze the different possible attacks and how UVote combats them. Evaluation of the system performance shows that these advantages come with minimal performance overhead. This highlights that UVote is a truly ubiquitous e-voting system.","PeriodicalId":260515,"journal":{"name":"2012 Third FTRA International Conference on Mobile, Ubiquitous, and Intelligent Computing","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115808883","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}
