Cloud computing with features like multitenancy, massive scalability, elasticity, pay as you go and self-provisioning resources help healthcare organizations achieve their goals. This paper presents a cloud computing model for integration of hospital information systems which is based on service oriented architecture. Having considered the requirements of HIS integration, the proposed model enables convenient access for all system components including both service provider and organizational components. To ensure security and high level of availability required for medical information, a Backup and Recovery Cloud service is included in our model to provide the users with the ability to retrieve information in critical situations. In addition, a minimum level of local basic services is included in our model that makes possible retrieving information when the hospital faces network disconnection from the cloud. A scenario-based evaluation method is used for assessment of the proposed model which shows adopting cloud computing technology is an effective way for integrating health information systems.","PeriodicalId":417179,"journal":{"name":"7'th International Symposium on Telecommunications (IST'2014)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127126458","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}

With this in mind, they have been able to attract millions of active users. However, they are being increasingly threatened by so-called covert social network botnets, a new generation of botnets that exploit social networks to establish covert command and control channels. Stego-botnets are typical covert social network botnets that use images shared on a social network to send the botmaster's commands and receive the information stolen from infected users. In this paper, we present SocialClymene, a PageRank-based negative reputation system to detect stego-botnets. At the heart of SocialClymene lies a negative reputation subsystem that analyzes images shared by social network users and calculates a negative reputation score for every user based on the user's history of participation in suspicious group activities. More precisely, the negative reputation score of every user is calculated by the sum of its incoming normalized suspicious values weighted by the negative reputation scores of its neighbors in a suspicious group activity graph. Our experimental results have shown that SocialClymene can efficiently detect stego-botnets with a high detection rate and an acceptable low false alarm rate.","PeriodicalId":417179,"journal":{"name":"7'th International Symposium on Telecommunications (IST'2014)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125681974","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}

Despite emotion recognition importance in system performance improvement, such as in ASR, not much research has been carried out in the speech emotion classification field. This paper is focused on finding more effective approaches to improve speaker emotional state classification methods. Two approaches are proposed for training and test phases while the Gaussian Mixture Model (GMM) is selected as the classifier. In these approaches, the motivation is to reduce the confusing information regions of emotional speech space and to increase salience of the discriminative regions. In the training phase, symmetric Kullback-Leibler Divergence (KLD) is used as a measure to detect the discriminative GMM mixtures while the confusing mixtures are ignored. This algorithm is known as KLD-GMM. In the test phase, the discriminative frames are recognized based on Frame Selection Decoding (FSD). This algorithm is known as FSD-GMM, when FSD algorithm is applied on KLD-GMM algorithm, the approach is named KLD-FSD-GMM algorithm. Two proposed algorithms have led to an average absolute improvement of about 7% in the emotion recognition performance in comparison with the baseline generalized GMM-based method.","PeriodicalId":417179,"journal":{"name":"7'th International Symposium on Telecommunications (IST'2014)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116171976","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}

Ordinary intrusion detection systems usually deal with network or OS attacks and could not detect database specific attacks. Therefore, the existence of Intrusion Detection Systems in the database is a necessity. In this paper, we propose a type of intrusion detection system for detecting attacks in both database transaction level and inter-transaction level (user task level). For this purpose, we propose a detection method at transaction level, which is based on describing the expected transactions within the database applications. Then at inter-transaction level, we propose a detection method that is based on anomaly detection and uses data mining to find temporal patterns and rules. The advantage of this system compared to the previous database intrusion detection systems is that it can detect malicious behaviors in both transaction and inter-transaction levels using a hybrid approach, including specification-based detection and anomaly detection. In order to evaluate the accuracy of the proposed system, some experiments have been done. The experimental evaluation results show high accuracy and effectiveness of the proposed system.","PeriodicalId":417179,"journal":{"name":"7'th International Symposium on Telecommunications (IST'2014)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121735663","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}
