However, cloud computing presents an added level of risk because essential services are often outsourced to a third party, which makes it harder to maintain data security and privacy, support data and service availability, and demonstrate compliance.While existing cloud computing threat detection and prevention techniques are improving, they are still not effective enough to meet the needs of next-generation systems, such as secure dynamic resource pools, high usability, and secure virtual machine migration. This paper aims to provide an understanding of the different potential attack vectors created by virtualization in a public Infrastructure-as-a-Service cloud, in particular, the security associated with the live virtual machine migration of jobs. The vectors will be investigated, concentrating on the threats emerging from various potential attackers (internal/external) to cloud systems. The overarching aim of this study, therefore, is to design and develop a secure live virtual machine migration framework that enables a virtual trusted platform module for multiple virtual machines running on a hardware platform while maintaining the cloud system’s integrity.","PeriodicalId":398108,"journal":{"name":"2018 Eleventh International Conference on Mobile Computing and Ubiquitous Network (ICMU)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121933412","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 recent years, these systems have generally been implemented as a Web system using cloud computing. The configuration used for the safety confirmation system included a Web server and DB server, amongst others, and these resources can be easily procured by cloud computing. In addition, implementation in the cloud has many merits such as a shortened development period and accelerated service start time. However, cloud computing is a system on the Internet; thus, there is concern about the risk of illegal access from the outside and information leakage. The safety confirmation system requires a secure system infrastructure in which to store attribute information and users’ personal information. Therefore, a cloud-based safety confirmation system would need to be convenient to use and secure. In this paper, we propose to improve the safety by constructing the safety confirmation system in a virtual private cloud environment. The evaluation of the system showed that it was possible to prevent external illegal access and information leakage and to operate the safety confirmation system such that it was highly convenient to use.","PeriodicalId":398108,"journal":{"name":"2018 Eleventh International Conference on Mobile Computing and Ubiquitous Network (ICMU)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127112847","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}

Interactive video type CAPTCHAs that attempt to detect this attack by using delay time due to communication relays have been proposed. However, these approaches remain insufficiently resistant to bots. We propose a CAPTCHA that combines resistant to automated and relay attacks. In our CAPTCHA, the users recognize a moving object (target object) from among a number of randomly appearing decoy objects and tracks the target with mouse cursor. The users pass the test when they were able to track the target for a certain time. Since the target object moves quickly, the delay makes it difficult for a remote solver to break the CAPTCHA during a relay attack. It is also difficult for a bot to track the target using image processing because it has same looks of the decoys. We evaluated our CAPTCHA’s resistance to relay and automated attacks. Our results show that, if our CAPTHCA’s parameters are set suitable value, a relay attack cannot be established economically and false acceptance rate with bot could be reduced to 0.01% without affecting human success rate.","PeriodicalId":398108,"journal":{"name":"2018 Eleventh International Conference on Mobile Computing and Ubiquitous Network (ICMU)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128275229","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 propose a method to estimate low of pedestrians walking on the sidewalks. Our goal is to achieve high accuracy with wide area coverage at low cost. For this purpose, we use dashboard cameras (dashcams) recently wide-spreading for providing evidence on accidents, etc.Our method combines Deep Learning-based pedestrian detection and model-based tracking to overcome the challenges of frequent occlusion (overlaps of objects in images) and false positives. In pedestrian detection, faces and backs of heads are separately detected to understand moving directions of pedestrians as well as their existence by applying CNN (Convolutional Neural Networks) and LSTM (Long-Short-Term-Memory). Then, the trajectories of the detected bounding boxes are estimated based on location and color similarities with the knowledge about moving speeds of vehicles and pedestrians.Through the evaluation using real dashcam videos, we have confirmed that our method works well, showing within ±13.6% mean absolute error rate of bi-directional people low estimation.","PeriodicalId":398108,"journal":{"name":"2018 Eleventh International Conference on Mobile Computing and Ubiquitous Network (ICMU)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130140130","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}

Graphical User Interface (GUI) applications are frequently written in high-level programming languages, which provide automatic memory management: placement and deletion of memory objects is not performed manually; instead, an underlying software component called a Garbage Collector (GC) handles this. Nevertheless, the GC policies and algorithms that are best suited for large datacenters are not necessarily ideal for a small, embedded device. Therefore, in this paper, we present GUI GC, a JavaFX GUI benchmark, which we use to compare the performance of the four GC policies of the IBM J9 Java runtime on a resource-constrained environment. Overall, our experiments suggest that the default policy Gencon, outperformed its counterparts. Additionally, the region-based policy, Balanced, did not fully utilize blocking times; thus, using GUI GC, we conducted experiments with explicit GC invocations that measured significant improvements of up to 13.22% when multiple CPUs were available.","PeriodicalId":398108,"journal":{"name":"2018 Eleventh International Conference on Mobile Computing and Ubiquitous Network (ICMU)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134368777","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}

The purpose of behavior change is to improve people’s lifestyle pattern or to maintain the improvement for a long time aiming to achieve a goal of promoting health condition improvement. In order to achieve the foundation of a new lifestyle, it is necessary to recognize the daily life patterns of users and give triggers to users in their daily life for behavior change. To realize this, in this study, we construct an interactive signage which is able to positively talk to the passing user and try to induce behavior change by sending visual stimulation and auditory stimulation. In this paper, we report the result of the investigation on users’ reactions and feelings to the proposed interactive signage. As a survey experiment, we set up 4 interactive signage on a floor of our university and asked 15 participants to carry a name tag with a BLE beacon during their daily life. There are 4 different dialogue scenarios and a scenario is posted to the participants when he/she approaches the interactive signage. Participants can respond to these scenarios through a touchscreen. Based on the result of the experiment, it is found that the interactive signage can induce behavior change effectively.","PeriodicalId":398108,"journal":{"name":"2018 Eleventh International Conference on Mobile Computing and Ubiquitous Network (ICMU)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116320199","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}
