Biometric sensors rapid prototyping on field-programmable gate arrays
2015
AbstractBiometric user authentication in large-scale distributed systems involves passive scanners and networked workstations and databases for user data acquisition, processing, and encryption. Unfortunately, traditional biometric authentication systems are prone to several attacks, such as Replay Attacks, Communication Attacks, and Database Attacks. Embedded biometric sensors overcome security limits of conventional software recognition systems, hiding its common attack points. The availability of mature reconfigurable hardware technology, such as field-programmable gate arrays, allows the developers to design and prototype the whole embedded biometric sensors. In this work, two strong an…
Comparing the Capabilities of Mobile Platforms for Business App Development
2015
Businesses increasingly embrace the possibilities of mobile computing. While there is broad advice for app developers in general, development of apps for enterprises is hardly covered. Business apps support internal processes and contribute to customer relationship management. The heterogeneity of platforms for mobile devices makes development difficult. At the same time, companies seek to support several platforms with their apps to maximize customer acceptance and to support the platforms best suited for their employees. Aiming at improving the knowledge on business app development, we present a framework for assessing mobile platforms. For this purpose, we have developed a distinct set o…
Combined People Position and Compass Detection for Context-aware Service Provision
2006
A novel technique is discussed for people identification and position sensing in augmented reality by the use of two cooperating technologies. People are provided with RFID tags for localization and context definition, and then visually investigated for identity checking and compass detection. The two technologies are discussed within an implementation of a case study dealing with context aware service provision for students in a campus.
A Social-Empowered Platform for Gathering Semantic Information
2013
Social Networks constitute the key ingredient for the huge success of the so called Social Web or Web 2.0. In social networks, a user has the possibility to interact with other users without the need of meeting them. The value of social applications benefit from the network effect, which states that the value of a service to a user arises from the number of people using the service. However, the associated semantics for this kind of applications, delivered through tagging, is generally scarce, thus narrowing the range of permissible operations for exploiting these data. In this paper, we present a semantic-based social platform that incorporates the benefits of semantic Web technologies int…
Electronic Commerce Transactions in a Mobile Computing Environment
2002
Internet E-commerce has been flourishing for the last few years, especially with the advent of World Wide Web. Mobile Electronic Commerce (MEC) has started recently to appear in the scene. It exploits the advantages of Internet, mobile computing and mobile communications in order to provide a large number of advanced services to mobile users. The potentials of MEC are enormous while related technical, business and legal issues become more complicated. The goal of this chapter is to present and discuss problems and identify requirements associated with the trading and billing of tangible and intangible goods in a mobile environment where mobile handheld devices are used for conducting the tr…
Building a Medical Research Cloud in the EASI-CLOUDS Project
2014
The demand for IT resources is constantly growing in the scientific area. The ability to store and process increasing amounts of data has transformed many research disciplines, like the life-sciences, which now rely on complex data processing and data analytics. Cloud environments are able to integrate and encapsulate possibly distributed resources and allow convenient and on-demand access to the corresponding services, tools, and complete work environments. The European research project EASI-CLOUDS (http://www. easi-clouds.eu) develops a platform for a convenient service delivery with special regard to service integration, monitoring, management, and Service Level Agreement (SLA) negotiati…

Introduction: Reframing Humans and Information Systems
2010
Recent development of information and communication technologies (ICT) provides information systems (IS) designers with new potentialities to build systems for various purposes. The ongoing digital convergence refers to and discloses new views on the interactive reconfiguration of technological and social arrangements on a large scale in the contemporary society (Tilson et al. 2009). In addition to work-related activities, people use new technologies for increasingly diverse purposes, for example organizing their domestic affairs, for finding information and e-services, and for staying in touch with their friends and relatives (Lyytinen and Yoo 2002; Sorensen and Yoo 2005; Iivari et al. 201…
Semantic Annotation and Retrieval of Services in the Cloud
2013
Recently, the economy has taken a downturn, which has forced many companies to reduce their costs in IT. This fact has, conversely, benefited the adoption of innovative computing models such as cloud computing, which allow businesses to reduce their fixed IT costs through outsourcing. As the number of cloud services available on the Internet grows, it is more and more difficult for companies to find those that can meet their needs. Under these circumstances, enabling a semantically-enriched search engine for cloud solutions can be a major breakthrough. In this paper, we present a fully-fledged platform based on semantics that (1) assist in generating a semantic description of cloud services…
Fast Secure Routing for Highly Mobile Large-Scale Ad-Hoc Vehicular Networks
2009
In highly mobile large-scale vehicular ad-hoc networks, routing protocols must be fast and efficient in terms of low routing discovery delay and communication overhead to support the applications such as car talk. Such requirement becomes more difficult to achieve when inducing security enhancement to tackle the authentication of routing messages. In this paper, we propose a lightweight (fast) secure routing protocol, Secure Proactive Tree-based Routing (SPTR) to hit these two points. SPTR makes use of the characteristics of VANET networks, that is, the traffic originates from or terminates at the gateway or road side unit. SPRT also takes advantages of certificate-less ID-based cryptograph…
