With IMS(IP Multimedia Subsystem) networks coming in to reality a new gaming experience can be provided to the subscribers by blending the gaming service with IMS service enablers such as presence, location etc. An intelligent service broker element like Service Capability Interaction Manager (SCIM) can deliver such blended services to the end users. Efficient charging of these services is very important and a real challenge since most of the interactive mobile gaming servers may not support standard 3GPP defined offline or online charging interfaces. Thus integrating these gaming servers requires lot of customization which may delay in rolling out new blended gaming services. Furthermore we propose a novel idea to charge such blended gaming services offline that are delivered through SCIM. We also propose a new offline charging interface Cf between SCIM and gaming application servers that enable exchange of charging information for the blended gaming service. We also discuss a typical IMS use case and its implementation details with a detailed call flow.","PeriodicalId":445751,"journal":{"name":"2011 IEEE 5th International Conference on Internet Multimedia Systems Architecture and Application","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115566496","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 ultimate goal of this separation is to facilitate the task of traffic auditing tools, namely in their struggle against botnets. The architecture was designed for domestic or enterprise facilities and uses the 802. IX authentication architecture as the base support infrastructure for dealing with unequivocal traffic binding to specific entities (persons or servers). Simultaneously, such binding uses virtual identities and encryption for preserving the privacy and protection of traffic originators from network eavesdroppers other than authorized traffic auditors. The traffic from each known originator is profiled with some detail, namely it includes a role tag and an application tag. Role tags are defined by originators and only partially follow a standard policy. On the contrary, application tags should follow a standard policy in order to reason about abnormal scenarios raised when correlating traffic from several instances of the same application. A first prototype was developed for Linux, using iptables and FreeRADIUS and conveying packet tagging information on a new IP option field.","PeriodicalId":445751,"journal":{"name":"2011 IEEE 5th International Conference on Internet Multimedia Systems Architecture and Application","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130558579","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}

On one side, sharing of monitoring data across domains may significantly help in detecting large scale threats and attacks; on the other side, data sharing conflicts with the need to protect network customers' privacy and confidentiality of business and operational information. The approach first proposed in this paper enables what we call “conditional data sharing”, i.e., permit cross-domain sharing of fine-grained organized subsets of network security data (called monitoring data feeds), only when a threshold number of domains are ready to reveal their data for the same feed. The proposed approach revolves on a careful combination of distributed threshold based cryptography with identity-based encryption. It appears scalable and easy to deploy, not requiring neither a-priori monitoring data feeds identification, nor explicit coordination among domains. Protection is accomplished by “simply” using different cryptographic keys per feed, and automatically permitting per-feed key reconstruction upon the occurrence of independent and asynchronous per-domain/per-feed alerts.","PeriodicalId":445751,"journal":{"name":"2011 IEEE 5th International Conference on Internet Multimedia Systems Architecture and Application","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130020636","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}

A possible way to alleviate these problems and improve the annotation quality is to obtain multiple annotations per image by assigning several annotators into the task. In the current work we present an approach to model the view of several annotators using four MPEG-7 descriptors and a well known data classifier. We apply keywords modelling to the annotation data collected in the framework of Commandaria project where sixteen non-expert users annotated a set of a hundred images using a predefined set of keywords. The images sharing a common keyword are grouped together and used for the creation of the visual model corresponds to this keyword. Finally, the created models used to classify the images into the keyword classes in terms of 2-classes combinations using the 10-fold cross-validation technique. The experimental results are examined under two perspectives: First, in terms of the separation ability of the various keyword classes and second, in terms of the efficiency of the four visual descriptors as far as the image classification task is concerned.","PeriodicalId":445751,"journal":{"name":"2011 IEEE 5th International Conference on Internet Multimedia Systems Architecture and Application","volume":"13 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114542134","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}
