An improved iris recognition system based on even symmetry Gabor wavelet is proposed in this paper. In iris image preprocess, an effective segmentation and eyelids occlusion detection approach are introduced. During recognition, only the imaginary part of complex 2-D Gabor filter is used in coding for shorter code length but without affecting the recognition performance. A simple effective filter parameters selection scheme is proposed at the same time. Experimental results on CASIA1.0 and ICE 2005 databases clearly demonstrate that our improved methods can achieve highly accurate iris recognition with a short code length.

In this paper, we propose a novel automatic gain control (AGC) algorithm as a solution to improve the signal reception performance based on the IEEE 802.15.4a chirp spread spectrum (CSS) over indoor fading channels. The CSS signals are composed of low-band and high-band signals whose frequency characteristics are different because of multipath fading in indoor environment. It is not appropriate to apply only one conventional AGC which regardless of the different bands, where the received signals are contaminated by quantization noise or clipped. The proposed AGC algorithm is based on two AGCs which are designed to be matched well with low-band and high-band signals separately.

The trust issue in distributed e-commerce systems has attracted much research attention in recent years. Existing e-commerce systems have presented trust management models which provide reputation information to buyers. However, more comprehensive models should be proposed to more precisely predict the trust level of sellers on potential transactions, and to defeat several kinds of possible attacks. This paper makes an effort to design PTME, a probability-based trust management model for distributed e-commerce, which is an attack-resistant trust model for evaluating and propagating reputation in distributed e-commerce systems. In this paper we describe the possible attacks on existing systems. Our model is then proposed to overcome these attacks. We provide a probability-based framework and detail approaches for this model. The performance evaluation and security analysis of PTME are provided to show its effectiveness.

Most previous query expansion researches are based on pseudo relevant documents. In this study, we present a novel expansion method by clustering the real user log. Because not all of the clicked pages are suitable for query expansion, we de-noised the clicked results by reliability to enhance the performance. After HTML labels removing, the page body contents are clustered and the cluster centers cover various aspects of the original query. The terms used in log queries can provide a better choice of features, from the user's point of view, for summarizing the web pages that were clicked from these queries. Therefore, the associated queries, reverse queries, webpage title and keyword phrases are combined with the cluster centers to attain high-quality expansion terms for new queries. We also propose a new terminology extraction method through Baidu Baike. It can identify and extract the terminology phrase based on the manual edited dictionary online.

Anthentication is a mechanism to establish proof of identities. Traditional password authentication could not provide enough security for the information system when it faces the most modern means of attack. The problem could be solved by taking token authentication, but as a new authentication system, it is difficult connecting with existed authentication systems, especially in the authorized access control system. In this paper, we propose a new token authentication scheme, which can closely integrate with the traditional authentication system to form a seamless interface and directly use the corresponding authorization and the access control service, and realize a prototype system finally. In our model of authentication, we transform the challenge-response token authentication to password authentication, which solves the secure problem of the password authentication; develope a mobile phone token software based on the lightweight crypt package from Bouncy Castle and the J2ME platform, which solves scheme's feasible problem; design a bluetooth communication model between the mobile phone token and the PC; complete the development of mobile phone token authentication prototype system finally.

The computer may cause information leakage when working. It has become an extremely urgent question studied now. The electromagnetic leakage principle of the computer video signal was analyzed in this paper because the video cable that connects a host to a monitor is thought as a main electromagnetic radiation part on the base of the working principle of a VDU. The information leakage approach, the red and black signals and the character analysis are presented. The paper studies the electromagnetic radiation of the red signals transmitting through the video cable and analyzes their waveform characteristic. Thus the radiation characteristic of the video signal is mastered, which can provide a theoretical basis for the recovery of the video information, protection method and technique measure.

This paper presents a new method to select a segment-to-segment matching by analysing signature verification, accordingly curve segments used in signature verification and the regional feature contained in the curve segment are picked-up and the regional features are selected by ant colony optimization (ACO) algorithm and genetic algorithms(GAs). Namely, features selected are first encoded into chromosome, and descendible types are founded by ACOGA improved locally. The essential advantages of ACO including cooperativity, obustness, positive feedback and distributed nature were discuss and also the disadvantages of low convergence speed while the high adaptability of GAs were discussed too. Meanwhile, cross operation and mutation of genetic algorithms were introduced into the ACO. A new crossover method is also proposed to determine the number of curve segments. The experiment shows that the algorithms proposed can accurately find optimal features for signature verification and bring the lower FRR and FAR, thereby the veracity in online signature verification is enhanced.

The success of the user generated content raises the new idea of enabling end-users to create their own services. User generated service will become the next big user-driven hype in the technology arena. This paper presents an overall view of the user generated service, from both technical and business perspective. We clarify the concept of user generated service, analysis the challenges, and illustrate the current platforms/tools in the classification of tech-inclined users and non-tech users. The underlying key technologies, incoming trends, as well as the future research topics, are also detailed.
