Analysis on the popularity of online contents is one of the hottest interests which has triggered intensive research. Our research focuses on measuring the popularity of online posts within specified topics, such as “drug abuse”, as it can be used to detect the crime and discover potential drug abusers. We measure the lifespan and the popularity of drug related posts in order to know the level of influence they made. Identifying popular posts online can help us reveal the trend, and also detect the latent danger and may prevent future crime. In this paper, the Comment Arrival Model is proposed to identify the lifespan and the comment frequency pattern of posts, which are considered the main factors to define post popularity. And we present 4 general models to measure the popularity of posts which can be applied in different social network platforms. We also did experiments and evaluated the performance of models in two popular social networks in Hong Kong, HK Discussion and Twitter.","PeriodicalId":220165,"journal":{"name":"Proceedings of 2011 IEEE International Conference on Intelligence and Security Informatics","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114631569","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}

Generally, peers create a temporary session during data exchange. The data might be trapped and disclosed by the intruders while exchanged over an insecure communication network. As there is no centralized control for data exchange among peers, we cannot assume any central third party security infrastructure (e.g. PKI) to protect confidential data of an eHealth P2PDBMS. So far, there is currently no available/existing security protocol for secured data exchange in eHealth P2PDBMS. In this paper we propose a security protocol for data exchange in eHealth P2PDBMSs based on pairing-based cryptography and data exchange policy. The proposed protocol allows the peers to compute their secret session keys dynamically by computing pairing on elliptic curve based on the policies between them during data exchange. Our proposed protocol is robust against the man-in-the middle attack, the masquerade attack and the replay attack.","PeriodicalId":220165,"journal":{"name":"Proceedings of 2011 IEEE International Conference on Intelligence and Security Informatics","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129233604","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}

Online forums are ideal platforms to draw attention from worldwide Internet users to the timely issues and some opinions in these discussions can be threatening the public safety. It is of great interest for the intelligence to identify clusters on these forums and capture the topics of discussions and their development. Previous work in cluster identification focused on social networks constructed by the direct interactions between users utilizing link analysis techniques. However, the direct interactions between users may only capture one potential relationship between forum users. Users who share common interests may not necessarily interact with each other directly. On the other hand, they may be active in similar events simultaneously. In this paper, we propose a temporal coherence analysis approach to identify clusters of users from the Dark Web data. Users are represented as vectors of activeness and clusters are extracted with the support of temporal coherence analysis. We tested our proposed methods on both synthetic dataset and real world dataset. Using the real-world Dark Web dataset, three clusters were identified and each cluster was also associated with a specific theme. It shows that a cluster of users participating in a theme of discussion can be discovered without using any content analysis but only using temporal analysis.","PeriodicalId":220165,"journal":{"name":"Proceedings of 2011 IEEE International Conference on Intelligence and Security Informatics","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134238933","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}
