With the development of network, web forensics is becoming more and more important due to the rampant cybercrime. In this paper, a forensics method of web browsing behavior based on association rule mining is presented. The method aims at providing the necessary data support to build the behavior pattern library for investigation. The records of the user's browsing history are collected to be analyzed. The obtained original data are pretreated to transactional data which are suitable for association rule mining. Frequent browsing time and frequent web browsing sequences are obtained from the transactional data by Apriori algorithm. The mining results are helpful for identification and recognition of anonymous or suspicious web browsing behavior patterns.

With the increasing popularization of low-cost smart mobile devices, which have the capability of short-range wireless communication, opportunistic networks aimed to meet different requirements start to put into practice. However, because of the mobility of nodes, links in opportunistic networks is intermittent and dynamic, which results in the problems of long delay time and low success rate of delivery. And these problems limit the further development of opportunistic networks. To solve these problems, this paper proposes a solution framework based on prediction, explores potential methods that are applicable to opportunistic networks and compares their performance and suitable application model.

The paper is mainly used to provide the equivalence of two algorithms of independent component analysis (ICA) based on the information bottleneck (IB). In the viewpoint of information theory, we attempt to explain the two classical algorithms of ICA by information bottleneck. Furthermore, via the numerical experiments with the synthetic data, sonic data, and image, ICA is proved to be an edificatory way to solve BSS successfully relying on the information theory. Finally, two realistic numerical experiments are conducted via FastICA in order to illustrate the efficiency and practicality of the algorithm as well as the drawbacks in the process of the recovery images the mixing images. © 2015 Qiao Ke et al.

A Novel Quantum Covert Channel Protocol Based on Any Quantum Secure Direct Communication Scheme

By analyzing the basic properties of unitary transformations used in a quantum secure direct communication (QSDC) protocol, we show the main idea why a covert channel can be established within any QSDC channel which employs unitary transformations to encode information. On the basis of the fact that the unitary transformations used in a QSDC protocol are secret and independent, a novel quantum covert channel protocol is proposed to transfer secret messages with unconditional security. The performance, including the imperceptibility, capacity and security of the proposed protocol are analyzed in detail.

Image saliency detection, which is aiming at locating meaningful objects in image and extracting the corresponding saliency map, has been attracting considerable attention. Most of existing saliency detection algorithms are dealing with uncompressed images, while numerous images are distributed and stored in JPEG format over Internet. Thus, this paper proposes a novel image saliency detection method dealing with JPEG images, which directly extracts 3 image low-level features (intensity, texture and color) from JPEG DCT blocks and then evaluates image saliency by calculating the shortest path from each internal point to the background. We compare our method with some state-of-the-art methods on the publicly available dataset MSRA-1000. Experimental results show that our method exhibits better performance in terms of all four evaluations than some state-of-the-art methods in our experiments. The final saliency maps indicate that our method can also produce satisfied saliency maps directly in compressed domain.

Finding justifications plays an important role in the development and maintenance of ontologies. It helps users or developers to understand the entailments by presenting the minimal subsets of the ontology which are responsible for the entailment (called justification). In our previous work, we have proposed a backtracking algorithm for finding justifications in description logic ΕL+, which underpins OWL 2 EL, a profile of the latest version of Web Ontology Language (OWL). However, the algorithm is not implemented. In this paper, we implement this algorithm and conduct experiments on some real world ontologies, including Snomed-CT. We compare our algorithm with a black-box algorithm for finding all justification in OWL 2 EL. The experimental results show that in most cases, the backtracking algorithm outperforms the black-box one. © Springer-Verlag Berlin Heidelberg 2013.

The problem of multi-label classification has attracted great interests in the last decade. Multi-label classification refers to the problems where an example that is represented by a single instance can be assigned to more than one category. Until now, most of the researches on multi-label classification have focused on supervised settings whose assumption is that large amount of labeled training data is available. Unfortunately, labeling training example is expensive and time-consuming, especially when it has more than one label. However, in many cases abundant unlabeled data is easy to obtain. Current attempts toward exploiting unlabeled data for multi-label classification work under the transductive setting, which aim at making predictions on existing unlabeled data while can not generalize to new unseen data. In this paper, the problem of inductive semi-supervised multi-label classification is studied, where a new approach named iMLCU, i.e. inductive Multi-Label Classification with Unlabeled data, is proposed. We formulate the inductive semi-supervised multi-label learning as an optimization problem of learning linear models and ConCave Convex Procedure (CCCP) is applied to optimize the non-convex optimization problem. Empirical studies on twelve diversified real-word multi-label learning tasks clearly validate the superiority of iMLCU against the other well-established multi-label learning approaches. © 2013 L.

Most application layer multicast (ALM) protocols build the delivery tree by the distributed way, which is necessary for large-scale group applications because of its good scalability. However, it is difficult for the distributed way to obtain high performance. To address the above problem, we study a VM-assisted ALM tree optimization solution (called ALMTO). The proposed solution uses cloud virtual machines (VMs) to collect the structure information on the ALM tree, and uses a centralized way to effectively reduce average latency of the ALM tree built by the distribute way.
