Alternative Method for OTP based Authentication in Areas with Weak Mobile Signal

Abstract: The rapid development of Internet-based applications and services has made websites a crucial part of our lives. More and more users are using online office services instead of desktop office software, online social services to engage in social activities, online information boards to post their business products, and online shopping to do their purchasing. To make all these online activities more secure One Time Password (OTP) are used. Due to weak mobile signal receiving this OTP becomes difficult.

Bringing Psychosocial Support to Headache Sufferers Using Information and Communication Technology: Lessons Learned from Asking Potential Users What they Want

Headaches are a major concern for which psychosocial interventions are recommended. However, headache sufferers do not always have ready access to these interventions. Technology has been used to improve access, especially in young people. To examine user preferences to inform the development of an Internet-based psychosocial intervention including smartphone technology, referred to as the Wireless Headache Intervention. The methodology followed a participatory design cycle, including 25 headache sufferers (14 to 28 years of age) who informed the prototype design. All participants were familiar with smartphones and the Internet. Through two iterative cycles of focus groups stratified according to age, qualitative data were collected by asking user preferences for the different planned components of the intervention (ie, smartphone pain diary, Internet-based self-management treatment, social support) and other relevant aspects (ie, smartphone versus computer delivery, and ways of reaching target audience). NVivo 8 with content analysis was used to analyze data and reflect themes as guided by the thematic survey. Participants reported a preference for completing the smartphone pain diary on a daily basis. Participants believed that the program should facilitate easy access to information regarding headaches and management strategies. They also wanted access to other headache sufferers and experts. Participants believed that the program should be customizable and interactive. They reinforced the need and value of an integrated smartphone and Internet-based application. The results provide insight into a participatory design to guide design decisions for the type of intervention for which success relies largely on self-motivation. The results also provide recommendations for design of similar interventions that may benefit from the integration of mobile applications to Internet-based interventions. The present research contributes to the theoretical frameworks that have been formulated for the development of Internet-based applications.

Ws-AC: A Fine Grained Access Control System for Web Services

The emerging Web service technology has enabled the development of Internet-based applications that integrate distributed and heterogeneous systems and processes which are owned by different organizations. However, while Web services are rapidly becoming a fundamental paradigm for the development of complex Web applications, several security issues still need to be addressed. Among the various open issues concerning security, an important issue is represented by the development of suitable access control models, able to restrict access to Web services to authorized users. In this paper we present an innovative access control model for Web services. The model is characterized by a number of key features, including identity attributes and service negotiation capabilities. We formally define the protocol for carrying on negotiations, by specifying the types of message to be exchanged and their contents, based on which requestor and provider can reach an agreement about security requirements and services. We also discuss the architecture of the prototype we are currently implementing. As part of the architecture we propose a mechanism for mapping our policies onto the WS-Policy standard which provides a standardized grammar for expressing Web services policies.

From the mainframe to the internet: the evolution of Moore's Extended Nutrient (MENu) database

Moore's Extended Nutrient (MENu) database first had its beginnings at the Pennington Biomedical Research Center as The Extended Table of Nutrient Values (ETNV) in 1990, having originated in the early 1960s as one of the first computerized nutrient databases in the US. The ETNV received its prominence in the scientific community as the database of the long-term Bogalusa Heart Study. In 1993, its movement from a mainframe designed computerized nutrient database system to a PC-based system was initiated. During the early to late 1990s the MENu database supported two NIH-funded clinical applications, DELTA (Dietary Effects on Lipids and Thrombogenic Activity) and DASH (Dietary Approaches to Stop Hypertension); it was used for menu design in these feeding trials. This database has undergone many changes over the years to meet the needs of researchers at Pennington and those needs identified by collaborators in federally funded projects. Over the past few years, Pennington has been involved in several different types of military nutrition research projects. One such project involved the need to access the MENu database components from remote locations via the internet. Several security issues needed to be dealt with since we were working with the Department of Defense. The system access was designed to deal with these issues and yet support use from any remote location with internet access. Dietitians and other military nutrition professionals were issued the client software along with individual logon IDs and passwords. They accessed the recipe entry and menu design applications, in addition to the entire nutrient composition files which includes the USDA Standard Reference and Survey Databases and other special user foods, including the special formulations used by the military. The tree design of the MENu database allows for the ease of location of menus and recipes by the military nutrition division personnel and facilitates the revision/entry of other items needed. Efforts are currently underway to address additional internet-based application development, including dietary assessment modules.

Designing wrapper components for e-services in integrating heterogeneous systems

Component-based approaches are becoming more and more popular to support Internet-based application development. Different component modeling approaches, however, can be adopted, obtaining different abstraction levels (either conceptual or operational). In this paper we present a component-based architecture for the design of e-applications, and discuss the concept of wrapper components as building blocks for the development of e-services, where these services are based on legacy systems. We discuss their characteristics and their applicability in Internet-based application development.

Web-Based Expert Geographical Information System for Advanced Transportation Management Systems

The Internet is fast becoming the standard environment for client-server applications that involve multiple users. The proliferation of Internet-based application development tools opens new doors to transportation researchers who work in real-time decision support system development. In the 1990s, one of the most important problems in advanced transportation management systems research was the development of better incident management systems. Although the incident management process has been well studied, the development of real-time decision support systems that can be used by all the involved agencies remains a challenging area of transportation engineering research. Existing incident management systems are developed on various traditional computing platforms, including UNIX and Windows. However, with the advent of the World Wide Web and Internet-based programming tools such as Java, it is possible to develop platform independent decision support tools for the incident management agencies. Web-based support tools offer an invaluable opportunity to develop next-generation online decision support tools for real-time traffic management. The applicability of Web-based tools to the development of online decision support systems for incident management is explored and demonstrated, and a prototype incident management decision support system (DSS) that has most of the capabilities of similar UNIX-based DSS support systems is developed and tested. Briefly described are the implementation and development of a prototype wide-area incident management system using Web-based tools.

Java, the Web, and software development

The author discusses how the World Wide Web and Java mark the death of fatware and the birth of dynamic computing built on rented components. The real paradigm shift will be the replacement of purchased software packages with transaction-oriented rental of Java applets attached to Web pages. In the move to a full-scale Internet based application development environment, developers are grappling with seven key issues: how to integrate e-mail, FTP, and HTML; the absolute need for security; the dearth of high-end visual tools; configuration management and version control; support for a flexible, sophisticated user interface; a common development environment; and performance, which has several components. Each of these issues are discussed by the author.
