Secure and fine-grained access control could hardly be guaranteed in today's centralized social networks which imply to totally delegate to the social networking management system the administration of user data. This paper presents an access control scheme based on relation declaration. In this scenario, social networking sites provide basic applications of social service while users' resources are...
Inventory management information to the standardization of enterprise materials management and automation, which replaces the original has been managed by artificial means to avoid the negligence of the management staff and the management of the quality of quality problems caused by the accident, for the timely, accurate, and efficient completion of the treasury to provide a strong materials management...
The system that integrating the information systems by using web services should provide a unified identity authentication single sign-on scheme for heterogeneous platforms. This paper introduces the characteristics of Kerberos based single sign-on and SAML based single sign-on. A single sign-on scheme which combines the advantages of the two schemes is designed based on analyzing the advantages and...
Agent technology is a rapidly-developing research field. It has been applied into fields like business, industry, military affairs, and education currently. Its characteristics like intelligence, self-determination and motion provide probability for settling the problems of special subject learning website construction. It is main purpose of thesis research to use MAS designing idea and Ms Agent technology...
In this paper, we consider a queueing systems with two parallel servers. Each server has a queue with infinite capacity. Customers arrive according to a Possion process and join the shortest queue. The service times of customers are independent and have generally distributed. If both queues have equal length, the new arrival with equal probability joins any of a queue. Jockeying between the queues...
An anti-PROXY detecting scheme based on characters is proposed. According the characters of data flow, viz. flow rate character, application character, content character, process character and behavior character, it is identified whether the user is an PROXY object or not. The next step anti-proxy action will be made in terms of practical policies. The scheme includes character collection, modes matching,...
In accordance with the ISO27001 series standards, this paper proposes the measures of e-campus information security risk evaluation. On the basis of identifying and evaluating the information assets, threats and vulnerabilities, this paper computes and analyzes the risk which e-campus will face, put forwards the criteria of dividing risk levels, and forms the model of e-campus information security...
With the development of social information technology, the examination mode under traditional educational system cannot suit current educational requirement. As an important side of modern teaching, computer-aided examination can reduce all kinds of subjective factors during every link to arrange examination more objective, faster and safer. This paper adopts B/S structure and designs a set of computer...
The traditional education system based on Web, in the remote education course lack certain intelligent and adaptability, unable to realize students' learning and teachers' teaching students according to their aptitude as needed, and Agent technology development to solve the above problem provides new ideas and methods. This paper researches the Agent technology used in the design of in a certain extent.
The technology of Data Warehouse and OLAP provide well analysis condition and present data means for electronic commerce of enterprise. But an OLAP system with only one server is inefficient and expensive; it doesn't meet the needs of all most middle and small-sized enterprises. In this study, a distributed OLAP system is designed which uses multi-microcomputers based local area network. The introduction...
In order to realize data synchronization between distributed information systems and design an information portal to provide convenient logon and browser services, financial information portal system of university was designed which contains the scheme of data synchronization based on service oriented architecture, web service and XML and the scheme of single sign on based on unified identity authentication...
Internet of things (IOT) based on EPC system is a revolutionary new technology of modern logistics management. IOT can obtain intelligent recognition, location, tracking, monitoring, management and its application in logistics management can achieve real-time tracking of goods, improvement of information transparency and visual management, thus can highly optimize logistics management. Presently in...
Mobile Agent technology mixs the technology of software system, communication system and distributed system together. The tasks are caught out through the automatic movement and running on the Internet so that most of the interbahavior can be made locally. In another word, mobile Agent transfers the disposal to the data side to handle it locally. Therefore,the research of mobile Agent has become a...
With a large amount of MMOG (Massively Multiplayer Online Game) like happy farm sweeping the country for the second time, the development of online games in our country becomes quicken up. However, under the influences of broadband and network status or other factors, online games must be facing a certain phenomenon of delay. So we must deal the problem with a certain synchronized algorithm to maximize...
As the Internet technology, speech technology progress and development, VOIP gradually become the mainstream of the present and future voice technology. VOIP and operation in IP network application system based on IP other as common security threat and weaknesses, including all the threat from IP network layer. VOIP technology safety problems also gradually revealed, more and more get more extensive...
In order to integrate stereo garage devices in a network and realize information sharing, a communication network based on RS485 is designed. The network is simple but stable and useful. Both hardware design and software design are introduced. In hardware design, some primary schematics are proposed. In software design, communication protocols and data structures are discussed. At last, the service...
To solve the problem that when coal mining enterprises involved in emergency rescue could not arrive in time, we develop the emergency rescue command information system based on Web GIS which can provide the function of managing emergency incident, dynamic playing emergency incident, managing historical events and displaying maps. The system provides evidence for rescuing when coal mine accident happens...
Computer experiments play a very important role in computer major education. How to make the students master various computer skills better by the experiments is always a big challenge for the teachers. Here the method of micro-test is put forward to improve the experimental effect. Combined with some major factors like the course's features, the students' knowledge structure, their psychology, the...
Based on analyzing large amount of literatures of the recommender system for mobile commence both home and abroad, this paper summarized its existing problems such as high-dimensional sparse data, centralized management, poor scalability and robust of the recommender system. Then, this paper designed a cloud computing oriented recommender system for mobile commence and presented a novel distributed...
There are many difficulties in data exchanging and sharing among health and medical information systems. This paper introduces some key techniques of the solution, which include the adoption of P2P communication mode, the framework for heterogeneous data integrating and semi-structured data mapping. These techniques employ distributed data storage and XML technology, which makes the system low in...
