Contemporary implicit authentication schemes operate at the device level such that they neither discriminate between data from different applications nor make any assumption about the nature of the application that the user is currently using. In this paper, we challenge the device-centric approach to implicit authentication on smartphones. We argue that the conventional approach of misuse detection at the device level has inherent limitations for mobile platforms. To this end, we analyze and empirically evaluate the device-centric nature of implicit authentication schemes to show their limitations in terms of detection accuracy, authentication overhead, and fine grained authentication control. To mitigate these limitations and for effective and pragmatic implicit authentication on the mobile platform, we propose a novel application-centric implicit authentication approach. We observe that for implicit authentication, an application knows best on when to authenticate and how to authenticate. Therefore, we delegate the implicit authentication task to the application and let the application provider decide when and how to authenticate a user in order to protect the owner's personal information. Our proposed application-centric implicit authentication approach improves accuracy and provides fine grained authentication control with low authentication overhead. Future research in this domain will benefit from our findings to provide pragmatic implicit authentication solutions.","PeriodicalId":360291,"journal":{"name":"Proceedings of the 15th Workshop on Mobile Computing Systems and Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115239879","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}

These efforts are motivated by the goals of lowering costs of data transfer, and reducing web latencies and device energy consumption. While these efforts have adopted different approaches to cloud-based browsing, there isn't a systematic understanding of the rich design space due to the proprietary nature of many of the solutions. In this paper, we take a step towards obtaining a better understanding by evaluating an extreme point in the design space that involves cloud support for most browsing functionality including execution of JavaScript (JS), and for compaction of data (e.g., image transcoding and compression). Our study is conducted in the context of Cloud Browser (CB), a popular commercially available browser that embodies this design point. Our results indicate that CB does not provide clear benefits over Direct (a device-based browser) either in energy or download time. For e.g. while CB decreases the download time compared to Direct for 38.87% of pages, it increases it by as much as 29.8s for other pages. Similarly while CB decreases the total energy by up to 20.77J compared to Direct for 52.7% of the pages, it increases it by up to 21.31J for other pages. Interestingly, even though CB does JS execution in the cloud, it increases the CPU and network energy for close to 50% of the pages. Overall our study indicates that cloud-based browsing is not always a win, and there are important trade-offs that must be carefully considered when moving functionality to the cloud.","PeriodicalId":360291,"journal":{"name":"Proceedings of the 15th Workshop on Mobile Computing Systems and Applications","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133636940","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}

Studies show that smartphone users are replacing their devices every 18 months, almost three times faster than desktop computers [1, 3], producing millions of discarded smartphones each year that end up lying in desk drawers, buried in landfills, or shipped to third-world countries where they are burned to extract precious metals, a process that damages both the health of those involved and the environment. Fortunately, the capabilities of discarded smartphones make them ideal for reuse. Instead of ending up in a landfill, a discarded smartphone could be integrated into a home security system or transformed into a health care device for the elderly. In this paper, we evaluate using discarded smartphones to replace traditional sensor network \"motes\". Compared with motes, discarded devices have many advantages: price, performance, connectivity, interfaces, and ease of programming. While the main question is whether their energy consumption is low enough to enable harvesting solutions to allow continuous operation, we present preliminary results indicating that this may be possible.","PeriodicalId":360291,"journal":{"name":"Proceedings of the 15th Workshop on Mobile Computing Systems and Applications","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125878355","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}

Currently, transparency into the power grid relies on utility companies and more fine-grained insight is provided by costly smart meter deployments. We claim that greater visibility into power grid conditions can be provided in an inexpensive and crowd-sourced manner independent of utility companies by leveraging existing smartphones. Our key insight is that an unmodified smartphone can detect power outages by monitoring changes to its own power state, locally verifying these outages using a variety of sensors that reduce the likelihood of false power outage reports, and corroborating actual reports with other phones through data aggregation in the cloud. The proposed approach enables a decentralized system that can scale, potentially providing researchers and concerned citizens with a powerful new tool to analyze the power grid and hold utility companies accountable for poor power quality. This paper demonstrates the viability of the basic idea, identifies a number of challenges that are specific to this application as well as ones that are common to many crowd-sourced applications, and highlights some improvements to smartphone operating systems that could better support such applications in the future.","PeriodicalId":360291,"journal":{"name":"Proceedings of the 15th Workshop on Mobile Computing Systems and Applications","volume":"251 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122391930","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}

But how should an app choose which network to use? There is no systematic solution to this problem today: in current practice the choice is almost always left to the user, who usually has no idea what's best. In fact, what's best for a user depends on the app's performance objectives (throughput, delay, object load time, etc.) and the user's constraints on cost and battery life. Besides, what's best for a single user or app must be balanced with what's best for the wireless network as a whole (individual optimality vs. social utility). This paper introduces Delphi, a transport-layer module to resolve these issues. Delphi has three noteworthy components: \"local learning\", in which a mobile device estimates or infers useful properties of different networks efficiently, \"property sharing\", in which mobile devices share what they learn with other nearby devices, and \"selection\", in which each node selects a network using what it has observed locally and/or from its neighbors.","PeriodicalId":360291,"journal":{"name":"Proceedings of the 15th Workshop on Mobile Computing Systems and Applications","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121385779","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}
