Abstract: This article mainly introduces the face recognition technology in its development，the present situation and common applications, and also discusses the facing recognition problems and solutions,finally it makes a brief outlook for the future of face recognition technology in development and application.

Abstract: The problem of effectively identifying of joining the network again is able to obtain the actual interest in the mobile business. The biggest problem of identifying the joining the network again is that even if a small amount of data will also require a lot of computing resources for comparison algorithm. This article using Hadoop technology proposed Hadoop's MapReduce technology heavy network fingerprint discriminant algorithm, which greatly improves the efficiency of heavy network fingerprint algorithm discrimination, the the discriminant algorithm proposed new higher discrimination accuracy than the original discrimination algorithm.

Abstract: The important method of the human recognition is to use the moment of the target. This paper is mainly dedicated to the method of human recognition use for Hu moment and Zernike moment, and separates some sports target using the minimum distance classifier. Comparing characteristic of these moments in specific application, have provided the certain basis for the choice of the invariant moments in the human recognition algorithm.

Abstract: Most current trust management systems cannot precisely reflect the dynamic feature of trust status. Based on the fundamental trust management principles and the thin client requirements in electronic commerce applications, by introducing the concept of Important Factor in trust calculation, a centralized trust management architecture and an efficient trust evaluation method were proposed. The trust evaluation method advocates defining as less formulae as possible to enable a simple and efficient trust evaluation system. And the parameters in trust evaluation equation can vary to adapt to different application environments. The simulation shows the new trust management model could precisely reflect the dynamic feature of trust status.

Abstract: This paper presents the implementation of CETPayment system which is an online payment system against CET (College English test). Hierarchical design is used to increase the flexibility of the system development. Althrough the workload of system design and implementation increased significantly, it can respond to rapidly changing business needs. Because of the use of hierarchical design, the system can be modified and adjusted quickly when it faced two major adjustments in the business logic. LINQ to SQL is used to make the system development process more automatic and effective, and avoid SQL injection attacks. A third-party payment company is chosen to process the payment requests of the candidates. A synchronous Reconciliation strategy is used to solve the problem of "single out". CET-CETPayment system can effectively reduce the work pressure of exam organization and management.

Abstract: With the development of the Internet, e-commerce is developing rapidly. E-commerce website plays an increasingly important role in e-commerce. The site operators need to know the popularity of the site and the site's success and inadequacies, and to find ways to further improve. Website investors need to know the operational status of the site, brand strength and potential for development. Consumers need to understand e-commerce services and product quality, business reputation. These need to be a comprehensive evaluation of the site. This article first analyzes the current state of domestic and international e-commerce site evaluation studies, and then proposes the evaluation method for e-commerce site based on neural network. Relative to the traditional manual and subjective evaluation, this method can greatly extend auto evaluation and reduce the arbitrary of the manual evaluation, thereby increasing the objectivity and accuracy of the evaluation.

Abstract: Firstly, this article focous on the requirements for RFID antenna of ecommerce--a fractal design of folded dipole antenna by moment method for simulation analysis of the designed antenna, the return loss performance of the antenna are calculated. In order to have more redundancy for the performance of the antennas in actual use when in all kinds of bad environment to function properly, we try to use methods of additional passive patch, microcosmic fractal structure and mirror compensation structure to improve the performance of the antenna. Then we compare the effects of multiple antenna performance improvement methods, and find the best optimization design project. According to the design of antenna, it’s resonant frequency is 2.4GHz, the minimum return loss value is -46.27dB, the bandwidth is 544MHz. Secondly, in view of the engineered practice, the article also discusses the influence of substrate parameters on the performance of the antenna in detail.

Abstract: The means of active recommendation is now increasingly applied to many different domains as it might meet users’ growing demands of personalized information service in process of selective purchasing for products, and research of recommendation technology based on user’s characteristics has been a key role in study area of active recommendation. However, investigations were performed to view there are still some deficiencies on existing methods. Therefore, an active recommendation method based on users’ static and dynamic characteristics is present and this paper proceeds as following. Firstly, feature model of user interests is constructed by analyzing static and dynamic data of target users for specific recommend. After that, neighbor users who have similar attributes with object user are found by reference to user model. Last, preference of intended user for other resources is reasonably predetermined by calculating interestingness with combination of neighbors, finally in this way can the main theory basis of recommendation comes into being. So in this paper a new approach based on users’ characteristics is provided, and it is shown with this method can effectively solve problem of shortage of satisfaction of traditional recommendation.

Abstract: As an information carrier, campus card has the functions of campus consumption, identity authentication, library management, and seeing the doctor in school hospital etc.. At present, there are three representative campus card depositing mechanism namely cash recharge, recharge and depositing through depositing machine and the recharge and depositing by the Bank deducting, all of which have the shortcomings of cumbersome process, information disclosure, the limit of the deposit amount and so on. For these, we put forward the web-based campus card's deposit programs - network recharge and depositing as well as the improvement program for the terminal POS. What's more, we came up with the agreed function dynamically password to ensure the user's financial and service security.

Abstract: Based on the characteristics of e-business website and information ecology theory, we analyzed the meaning and uniqueness of information ecology chain on e-business website. Through discussing the function and interaction of all elements which information ecology chain of business website has, we point out the operating mechanism which is required by the information ecology chain of electronic business website when it developed healthily.
