The Distributed m-healthcare cloud computing system considerably facilitates secure and efficient patient treatment for medical consultation by sharing personal health information among the healthcare providers. This system should bring about the challenge of keeping both the data confidentiality and patients’ identity privacy simultaneously. Many existing access control and anonymous authentication schemes cannot be straightforwardly exploited.…

Statistics from security firms, research institutions and government organizations show that the numbers of data-leak instances have grown rapidly in recent years. Among various data-leak cases, human mistakes are one of the main causes of data loss. There exist solutions detecting inadvertent sensitive data leaks caused by human mistakes and to provide alerts for organizations.…

ABSTRACT: With data storage and sharing services in the cloud, users can easily modify and share data as a group. To ensure share data integrity can be verified publicly, users in the group need to compute signatures on all the blocks in shared data. Different blocks in shared data are generally signed by different 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…

Malware Propagation in Large-Scale NetworksAbstract—Malware is pervasive in networks, and poses a critical threat to network security. However, we have very limitedunderstanding of malware behavior in networks to date. In this paper, we investigate how malware propagates in networks from aglobal perspective. We formulate the problem, and establish a rigorous two layer epidemic model for…

Abstract—This paper proposes a lossless, a reversible, and a combined data hiding schemes for ciphertext images encrypted by public key cryptosystems with probabilistic and homomorphic properties. In the lossless scheme, the ciphertext pixels are replaced with new values to embed the additional data into several LSB-planes of ciphertext pixels by multi-layer wet paper coding. Then,…

Abstract: Top-k query is an important operation to return a set of interesting points in a potentially huge data space. It is analyzed in this paper that the existing algorithms cannot process top-k query on massive data efficiently. This paper proposes a novel table-scan-based T2S algorithm to efficiently compute top-k results on massive data. T2S…

Continuous and Transparent User IdentityVerification for Secure Internet ServicesAndrea Ceccarelli, Leonardo Montecchi, Francesco Brancati, Paolo Lollini,Angelo Marguglio, and Andrea Bondavalli, Member, IEEEAbstract—Session management in distributed Internet services is traditionally based on username and password, explicit logouts andmechanisms of user session expiration using classic timeouts. Emerging biometric solutions allow substituting username andpassword with biometric data during…

Abstract—This article considers the joint problem of packetscheduling and self-localization in an underwater acoustic sensornetwork with randomly distributed nodes. In terms of packetscheduling, our goal is to minimize the localization time, andto do so we consider two packet transmission schemes, namelya collision-free scheme (CFS), and a collision-tolerant scheme(CTS). The required localization time is formulated for…
