In particular, outsourcing sensitive data to untrusted cloud service providers creates important security and regulatory compliance challenges. Encryption of the outsourced data has been introduced as an alternative to protect privacy and security. In the context of searchable symmetric encryption, many solutions have been proposed to perform efficient search on the encrypted outsourced data. Some of them achieve protecting privacy of outsourced data, but may disclose the access patterns (i.e., they disclose which data items are retrieved based on the query execution). Recently, it has been shown that such access pattern disclosures could be exploited even further to infer sensitive information about underlying data, even if the data is stored in encrypted form. To address the access pattern disclosures, oblivious RAM and heuristic based techniques are proposed. However, the overhead of oblivious RAM based solutions is too high in many cases, and the security and scalability of heuristic based techniques have not been carefully analyzed yet. In this paper, we provide the first framework to analyze and compare the security and efficiency of such heuristics (e.g., caching, fake data access, and data duplication). In addition, we provide extensive empirical analysis that yields important insights into how to use such heuristics effectively in practice; and we discuss how such heuristics can be combined to improve security and efficiency.","PeriodicalId":222111,"journal":{"name":"9th IEEE International Conference on Collaborative Computing: Networking, Applications and Worksharing","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125591541","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 recent report from Gartner indicates that IaaS will be the fastest growing area among all of the cloud service models in the near future, and thus it is strongly envisioned that multiple companies will use IaaS clouds to share information among them. However, the current access control mechanisms in IaaS platforms do not have the ability to enable flexible data sharing among companies while addressing security problems such as information and privacy leaking. In this paper, we propose two IaaS cloud reference architectures that enforce cloud-level Chinese Wall security (CWS) policy to prevent information leaking among companies. The new architectures are also able to support customized domain level access control policies such as role-based access control (RBAC), privacy-preserving information retrieval, and single sign on (SSO). The reference architectures were implemented using Eucalyptus and its data storage service called Walrus; therefore, our approach can also be applied to commercial clouds like Amazon S3. The result of performance analysis has shown that our architectures are feasible, scalable, and efficient.","PeriodicalId":222111,"journal":{"name":"9th IEEE International Conference on Collaborative Computing: Networking, Applications and Worksharing","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133136563","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}

As a result, we introduce additional mechanisms to take the first step to improve awareness in complex cooperative work environments. After a short introduction to the concepts awareness, awareness mechanisms, and Enterprise 2.0 we describe a case study to find out patterns of awareness in collaborative work processes and the missing awareness support. We approach the problem by trying to understand which Enterprise 2.0 components are related to which awareness mechanisms, and to which degree Enterprise 2.0 fulfills awareness requirements of complex collaborative work. Our study results in the identification of two different categories: system- and user-related awareness mechanisms. Search, extensions, and signals - supporting system-related mechanisms - are the most common components that are already established by different tools. Authoring, links, and tags - assisting user-related mechanisms - on the other hand, have not been utilized yet. They are very powerful to create context and capture collective knowledge. To support this, we introduce additional awareness mechanisms like enter, annotate, rate, share, reference, select, mark, and label, to show how these three components can be implemented in enterprises. By doing so, we present the potential of Enterprise 2.0 to support awareness in cooperative work. The new map of awareness mechanisms to Enterprise 2.0 inform not only the developers of tools supporting (aware) collaboration but also practitioners working in teams to define their requirements to such tools.","PeriodicalId":222111,"journal":{"name":"9th IEEE International Conference on Collaborative Computing: Networking, Applications and Worksharing","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130631279","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}

Therefore, the need for designing more efficient and faster algorithms for these new types of problems. Specifically, from the field of social network analysis, we have the influence maximization problem. This is a problem with many possible applications in advertising, marketing, social studies, etc, where we have representations of influences by large scale graphs. Even though, the optimal solution of this problem, the minimum set of graph nodes which can influence a maximum set of nodes, is a NP-Hard problem, it is possible to devise an approximated solution to the problem. In this paper, we have proposed a novel algorithm for influence maximization analysis. This algorithm consist in two phases: the first one is an entropy based node ranking where entropy ranking is used to determine node importance in a directed weighted influence graph. The second phase computes the minimum cut using a novel metric. To test the propose algorithm, experiments were performed in several popular data sets to evaluate performance and the seed quality over the influences.","PeriodicalId":222111,"journal":{"name":"9th IEEE International Conference on Collaborative Computing: Networking, Applications and Worksharing","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130431965","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}
