Securely authenticating a human user without assistance from any auxiliary device in the presence of powerful passive adversaries is an important and challenging problem. Passive adversaries are those that can passively monitor, intercept, and analyze every part of the authentication procedure, except for an initial secret shared between the user and the server. In this paper, we propose a new secure authentication scheme called predicate-based authentication service (PAS). In this scheme, for the first time, the concept of a predicate is introduced for authentication. We conduct analysis on the proposed scheme and implement its prototype system. Our analytical data and experimental data illustrate that the PAS scheme can simultaneously achieve a desired level of security and user friendliness.

This contribution aims at unifying two recent trends in applied particle filtering (PF). The first trend is the major impact in simultaneous localization and mapping (SLAM) applications, utilizing the FastSLAM algorithm. The second one is the implications of the marginalized particle filter (MPF) or the Rao-Blackwellized particle filter (RBPF) in positioning and tracking applications. Using the standard FastSLAM algorithm, only low-dimensional vehicle models are computationally feasible. In this work, an algorithm is introduced which merges FastSLAM and MPF, and the result is an algorithm for SLAM applications, where state vectors of higher dimensions can be used. Results using experimental data from a UAV (helicopter) are presented. The algorithm fuses measurements from on-board inertial sensors (accelerometer and gyro) and vision in order to solve the SLAM problem, i.e., enable navigation over a long period of time.

In this paper, we present a novel approach to retrieve the person images that contain the identical clothing to a query image from the image set captured by multiple CCTV cameras. In order to measure the similarity of the clothing, we analyze the color information of the clothing area in the image. To find the clothing area, we detect the face area first. The clothing area is found based on the position of the face area. Then, we apply the color quantization to the clothing area. We build six color histograms based on the quantized color for six sub-regions defined in the clothing area. The feature vector for the clothing area is composed by using the color histograms. Similarity between two clothing areas is measured by Euclidean distance between the feature vectors. In the experimental results, our approach shows the better performance compared with the method that uses HSV histogram-based color analysis.

In this paper, a class of hybrid impulsive systems with time delays and stochastic effects are considered. We obtain some criteria on the global exponential stability in mean square for the impulsive stochastic delayed systems. To do this, differential inequalities and ℒ-operator inequalities are developed. An example is given to illustrate the effectiveness of our results.

The manual ontology construction can enhance accuracy of ontology construction than an automatic ontology construction. But much time and effort are needed. And it is hard to add the newly created concept, the instance and relation to the ontology one-by-one. So, the automatic construction of ontology is needed and the tools for an auto-construction and systems are needed. In this paper, we studied on the concept/instance automatic classification which is one of them. In order to classification of concept/instance, we made the concept rules and the instance rules using the patterns in terminology dictionary items. And a system was built. The precision of classification result of a concept and instance is 97.7%, 86.4%. The whole precision is 92.1%.

In this paper, we introduce and evaluate a computing model for marketable quality and profitability of corporations. We discuss the model prediction of the turning and transition periods based on data from two different sources. By applying these real data of some leading manufacturing corporations in Japan, we analyze the model accuracy. From the analysis, we conclude that even there are some differences between two sources data, the proposed model give a good approximation and prediction of the turning and transition periods of Japanese economy.
