There exist many unsolved problems in the traditional digital rights management of network media. For example, in the traditional management system it is hard to guarantee the quality of media works, to protect the copyrights, to find the effective profit model and so on. To solve these problems, we propose in this paper a network media's digital rights management scheme based on blockchain. Blockchain...
Online Public Opinion Systems (OPOS) target at collecting, analyzing, summarizing and monitoring massive public opinions on the Internet in real time. Meanwhile, OPOS often have the ability to identify the key or sudden events, and thus notify related people immediately for rapid responses to these events. As part of this endeavor, this paper introduces the architecture and techniques of an OPOS that...
Distributed interactive computing allows participants at different locations to interact with each other in real time. In this paper, we study the interaction times of continuous Distributed Interactive Applications (DIAs) in which the application states change due to not only user-initiated operations but also time passing. Given the clients and servers of a continuous DIA, its interaction time is...
Online social networking community is an important type of internet service. Large scale social network can be built upon the large quantities of user data kept by social networking community. We model the large scale social network on the live online community and evaluate the user relationship index from the model. We further use the user relationship index in analyzing the user relation data and...
The exponential growth of Web images has created a compelling need for innovative methods to retrieve and manage them. Automatic image annotation is an effective way for resolving this problem. In this paper, we propose a novel system that automatically annotates images by semantic corpus which is constructed by mining Web image data. It includes three parts: 1) constructing the semantic annotation...
The widely use of anonymous communication systems, which aim at protecting the privacy of Internet users, has posed significant challenges to the capability of tracing cyber crimes. To address the problems of anonymous abuse, Yu et al. recently developed a new class of flow marking technique for invisible traceback based on direct sequence spread spectrum (DSSS), utilizing a pseudo-noise (PN) code...
Nowadays congestion control problem of the intermediate nodes in the Internet has received extensively attention in networking and control community. In this paper, a novel adaptive PID (Proportional-Integral-Differential) controller based on neural networks for the problem of AQM with ECN marks is presented. Considering a previously developed nonlinear dynamic model of TCP/AQM system and the queue...
With the popularity of service-oriented computing, how to construct highly available service-oriented applications is becoming a hot topic in both the research and industry communities. As a fundamental problem in dynamic service selection, availability estimation is challenging because of the dynamic nature of Web services. To grasp the dynamic nature of Web services, we set up an experimental environment...
