MapReduce job, we consider to aggregate data with the same keys before sending them to remote reduce tasks. Although a similar function, called combine, has been already adopted by Hadoop, it operates immediately after a map task solely for its generated data, failing to exploit the data aggregation opportunities among multiple tasks on different machines.…

Abstract—Intelligently extracting knowledge from social mediahas recently attracted great interest from the Biomedical andHealth Informatics community to simultaneously improve healthcareoutcomes and reduce costs using consumer-generated opinion.We propose a two-step analysis framework that focuses on positiveand negative sentiment, as well as the side effects of treatment, inusers’ forum posts, and identifies user communities (modules) andinfluential users…

In this paper, we present a distributed structured approach to Sybil attack. This is derived from the fact that our approach is based on the neighbor similarity trust relationship among the neighbor peers. Given a P2P e-commerce trust relationship based on interest, the transactions among peers are flexible as each peer can decide to trade…

File sharing applications in mobile ad hoc networks (MANETs) have attracted more and more attention in recent years. The efficiency of file querying suffers from the distinctive properties of such networks including node mobility and limited communication range and resource. An intuitive method to alleviate this problem is to create file replicas in the network.…

k-Nearest Neighbor Classification overSemantically Secure Encrypted Relational DataBharath K. Samanthula, Member, IEEE, Yousef Elmehdwi, and Wei Jiang, Member, IEEEAbstract—Data Mining has wide applications in many areas such as banking, medicine, scientific research and among governmentagencies. Classification is one of the commonly used tasks in data mining applications. For the past decade, due to the rise…

—Media streaming applications have recently attracted a large number of users in the Internet. With the advent of thesebandwidth-intensive applications, it is economically inefficient to provide streaming distribution with guaranteed QoS relying only oncentral resources at a media content provider. Cloud computing offers an elastic infrastructure that media content providers (e.g., Videoon Demand (VoD) providers)…

We present a new method to identify navigation related Web usability problems based on comparing actual and anticipated usage patterns. The actual usage patterns can be extracted from Web server logs routinely recorded for operational websites by first processing the log data to identify users, user sessions, and user task-oriented transactions, and then applying a…

n wireless networks, transmission between legitimateusers can easily be overheard by an eavesdropper forinterception due to the broadcast nature of the wirelessmedium, making wireless transmission highly vulnerableto eavesdropping attacks. In order to achieve confidentialtransmission, existing communications systems typically adoptthe cryptographic techniques to prevent an eavesdropper fromtapping data transmission between legitimate users [1, 2]. Byconsidering symmetric…

Identity-Based Encryption (IBE) which simplifies the public key and certificate management at Public Key Infrastructure (PKI) is an important alternative to public key encryption. However, one of the main efficiency drawbacks of IBE is the overhead computation at Private Key Generator (PKG) during user revocation. Efficient revocation has been well studied in traditional PKI setting,…

In this paper proposes Searchable Public-Key Ciphertexts with Hidden Structures (SPCHS) for keyword search as fast as possible without sacrificing semantic security of the encrypted keywords. In SPCHS, all keyword-searchable ciphertexts are structured by hidden relations, and with the search trapdoor corresponding to a keyword, the minimum information of the relations is disclosed to a…

Existing social networking services recommend friends to users based on their social graphs, which may not be the most appropriate to reflect a user’s preferences on friend selection in real life. In this paper, we present Friendbook, a novel semantic-based friend recommendation system for social networks, which recommends friends to users based on their life…

In this paper, we propose an energy efficient virtual network embedding (EEVNE) approach for cloud computing networks, where power savings are introduced by consolidating resources in the network and data centers. We model our approach in an IP over WDM network using mixed integer linear programming (MILP). The performance of the EEVNE approach is compared…

Enabling Fine-grained Multi-keyword Search Supporting Classified Sub-dictionaries over Encrypted Cloud DataAbstract—Using cloud computing, individuals can store their data on remote servers and allow data access to public users through thecloud servers. As the outsourced data are likely to contain sensitive privacy information, they are typically encrypted before uploaded tothe cloud. This, however, significantly limits the…

In mobile cloud computing, a fundamental application is to outsource the mobile data to external cloud servers for scalable data storage. The outsourced data, however, need to be encrypted due to the privacy and confidentiality concerns of their owner. This results in the distinguished difficulties on the accurate search over the encrypted mobile cloud data.…
