A widely adopted identification technique, proposed by Lukas in [1], relies on the usage of the pattern noise left by the camera sensor as a fingerprint. This technique may perform badly when applied to images that have undergone lossy compression techniques, such as being saved as a low-quality JPEG image. In this paper, we firstly analyze the experimental performance of the identification technique by Lukas, when dealing with JPEG images saved using increasing compression rates. Then, we investigate if and how some of the enhanced sensor pattern noise extraction techniques proposed in literature are able to improve on the original technique in the considered cases. Our results show that, on a side, an increase in the compression rate of a JPEG image deeply affects the effectiveness of the identification process carried out using the Lukas technique. On the other side, we show that at least two of the considered enhanced sensor pattern noise extraction techniques succeed in recovering most part of this degradation.","PeriodicalId":290976,"journal":{"name":"2012 Sixth International Conference on Innovative Mobile and Internet Services in Ubiquitous Computing","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132189966","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 theme of this paper is how to create a better world using the information that people want to exchange with each other between the disabled and the general population. On the other hand, the main goal is to provide the information that they need from each other which can be displayed on the map in real-time. We propose a new location-based SNS application for the physically disabled population having three major characteristics of this application to be considered as follows: One uses Social Networking Service (SNS) by constructing a friend matching system such as Face book and Twitter, which are the most widely-used SNS in the world, the general population registers real-time information of a specific location on the map for the physically disabled population using SNS. This information with photos and messages is given and evaluated by users, and this system makes it easier to see that the menu in the GUI was implemented.","PeriodicalId":290976,"journal":{"name":"2012 Sixth International Conference on Innovative Mobile and Internet Services in Ubiquitous Computing","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126905726","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 can benefit a lot from appropriate placement policy, e.g. cost saving. In this paper, we raise a continuous virtual machine placement problem and propose an on-line algorithm to reduce the power consumption of clouds. Generic methods which deal with this problem with greedy manner will result in resource leak, a phenomenon of resource wasting. The direct consequence of this phenomenon is larger number of running PMs, which will cause higher power consumption. We prove it is an NP-complete problem to minimize the power consumption during the placement of VMs while the VM requests reach the clouds continuously. We propose a balanced algorithm with the principle of avoiding resource leak. The balanced algorithm handles the VM requests in real time and guarantees high resource utilization. The number of PMs and power consumption can be cut down as a result of high resource utilization. We evaluate the balanced algorithm via experiments with various simulations. Experimental results show that the balanced algorithm can reduce the number of running PMs effectively, so that, it has a significant efficiency on power saving.","PeriodicalId":290976,"journal":{"name":"2012 Sixth International Conference on Innovative Mobile and Internet Services in Ubiquitous Computing","volume":"297 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115924081","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}
