Whitepaper: The Legal Status of Spyware

by Indiana UniversityJan 01, 2008

Even though large-scale breaches grab the headlines, many victims of identity theft frequently cause the offending disclosure by unwittingly downloading software from the World Wide Web (""Web"") or responding to email ""Phishing"" and other online and offline scams. Although courts find a right to privacy in the United States Constitution, that right generally only protects citizens from invasions by the government, not by corporate America. Federal law enables spyware, adware, and phishing businesses to mine consumer data with impunity. This research paper demonstrates that although some laws are ineffective, others provide consumers with some minimal relief.


Whitepaper: Global Multimedia Collaboration System

by Indiana UniversityJan 01, 2008

Collaboration systems enable people in remote places to communicate and cooperate. And most collaboration systems are not designed in the approach of an open system and cannot communicate with each other. It will bring substantial benefits to Internet users if one can build an integrated collaboration environment, which combines conferencing, streaming, instant messaging as well as other collaboration applications into a single easy-to-use, intuitive environment. However, traditional collaboration systems can only provide limited collaboration capabilities to a small group of people in a local or private community.


Whitepaper: AJAX Integration Approach for Collaborative Calendar-Server Web Services

by Indiana UniversityJan 01, 2008

The proliferation of the impressive web technologies provides developers with a way to produce performance efficient, usable, rich and interactive web based applications. This research paper present a generic and performance efficient framework for integrating AJAX models into the iCalendar based Collaborative Calendar-Server Web Services system. Web Services increase the level of interoperability between different applications running on different platforms. Web Service systems support XML based message exchange mechanism, which enable to develop loose coupled distributed systems all around the world.


Whitepaper: Integrating AJAX Approach Into GIS Visualization Web Services

by Indiana UniversityJan 01, 2008

AJAX is an important web development model for the browser based web applications. It uses several technologies which come together and incorporate to create a powerful new model. Technologies forming AJAX model such as XML JavaScript, HTTP and XHTML are widely-used and well-known. High performance Google mapping uses this new powerful browser based application model. Web Services are self-contained, self-describing, and modular. Unlike earlier, more tightly coupled distributed object approaches such as Common Objects Request Brokers (CORBA), Web Service systems support an XML message-centric approach, allowing us to build loosely coupled, highly distributed systems that span organizations.


Whitepaper: Investigating the Performance of Audio/Video Service Architecture I: Single Broker

by Indiana UniversityJan 01, 2008

The availability of increasing network bandwidth and computing power provides new opportunities for distant communication and collaboration over Internet. The number of homes and small offices with broadband Internet connections are increasing rapidly. Even the cell phones will have broadband Internet access in the near future with the deployment of 3G standards. Therefore, it is not inconceivable to imagine that the trend in the increasing usage of videoconferencing systems will continue by accelerating. This will require universally accessible and scalable videoconferencing systems that can deliver thousands of concurrent audio and video streams.


Whitepaper: Using a Java Query Analyzer to Translate Generic Query to SQL, XPath and XQuery

by Indiana UniversityJan 01, 2008

This paper published by Indiana University application describes how developers are faced with SQL extended to provide XML support along with new query languages, such as XPath and XQuery. At the Indiana University Digital Library Program, various data-driven digital library collection applications are developed. A Java Query Analyzer (JQA) was developed to simplify interaction with heterogeneous database and storage systems.


Whitepaper: Service-Oriented Architecture for a Scalable Videoconferencing System

by Indiana UniversityJan 01, 2008

The availability of increasing network bandwidth and computing power provides new opportunities for videoconferencing systems over Internet. Multimedia capable devices with broadband Internet connections are spreading rapidly. Even cell phones will have broadband internet access in the near future. This requires universally accessible and scalable videoconferencing systems that can deliver thousands of concurrent audio and video streams. However, developing videoconferencing systems over Internet is a challenging task, since audio and video communications require high bandwidth and low latency.


Whitepaper: Making SVG a Web Service in a Message-Based MVC Architecture

by Indiana UniversityJan 01, 2008

This research paper from Indiana University explains Scalable Vector Graphics (SVG) browser in a Web Service architecture separating the rendering from the W3C DOM processing of events. They describe this in a message-based Model-View-Controller (M-MVC) architecture and implement it with a powerful publish subscribe messaging infrastructure. A Web Services oriented architecture with services loosely coupled by the exchange of messages is becoming an increasingly important feature in the deployment of Internet applications. The broad applicability of this approach includes enterprise software, e-Learning, e-Science and e-Business. This work provides a general framework for integrating Desktop and Web Service applications.


Whitepaper: Information Services for Grid/Web Service Oriented Architecture (SOA) Based Geospatial Applications

by Indiana UniversityJan 01, 2008

Geographical Information Systems (GIS) presents data-intensive environment for acquiring, processing and sharing geo-data among interested parties. In SOA-based systems, Information Services support the discovery and handling of these geospatial services. The implementation of this approach is being used to support a GIS workflow system which is a part of NASA Solid Earth Virtual Observatory (SERVO) Grid project. This paper discusses the relevant work explaining different approaches for service discovery in GIS domain, authors? contribution in GIS compatible Information Services, architectural design followed by an application case scenario and with future work.


Whitepaper: Building Messaging Substrates for Web and Grid Applications

by Indiana UniversityJan 01, 2008

With the advent of the Open Grid Computing Architecture (OGSA) and the UK e-Science program, Grid computing has aligned itself with Web Service standards activities: Grid infrastructure will be Web Service infrastructure, although the aggressiveness in developing and adopting extensions is a matter of debate. The current general consensus is that Web and Grid Services should follow Service Oriented Architecture (SOA) principles, such as discussed by the World Wide Web Consortium’s Web Service Architecture working group.
