PGMAP: a privacy guaranteed mutual authentication protocol conforming to EPC class 1 gen 2 standards

To resolve the security vulnerabilities and comply with EPC Class 1 Gen 2 UHF RFID (EPC C1G2) Standard at the same time, we present a Privacy Guaranteed Mutual Authentication Protocol (PGMAP). By utilizing the existing functions and memory bank of tag, we amend the processing sequence based on current EPC architecture. An auto-updating index number IDS is enrolled to provide privacy protection to EPC code and a set of light weight algorithms utilizing tag's PRNG are added for authentication. Several attacks to the existing security solutions can be effectively resolved in our protocol. © 2008 IEEE.published_or_final_versionThe IEEE International Conference on e-Business Engineering (ICEBE 2008), Xi'an, China, 22-24 October 2008.

SOA-Driven Business-Software Alignment

The alignment of business processes and their supporting application software is a major concern during the initial software design phases. This paper proposes a design approach addressing this problem of business-software alignment. The approach takes an initial business model as a basis in deriving refined models that target a service-oriented software implementation. The approach explicitly identifies a software modeling level at which software modules are represented as services in a technology-platformindependent way. This model-driven service-oriented approach has the following properties: (i) there is a forced alignment (consistency) between business processes and supporting applications; (ii) changes in the business environment can be traced to the application and vice versa, via model relationships; (iii) the software modules modeled as services have a high degree of autonomy; (iv) migration to new technology platforms can be supported through the platform independent software model

Business integration models in the context of web services.

E-commerce development and applications have been bringing the Internet to business and marketing and reforming our current business styles and processes. The rapid development of the Web, in particular, the introduction of the semantic web and web service technologies, enables business processes, modeling and management to enter an entirely new stage. Traditional web based business data and transactions can now be analyzed, extracted and modeled to discover new business rules and to form new business strategies, let alone mining the business data in order to classify customers or products. In this paper, we investigate and analyze the business integration models in the context of web services using a micro-payment system because a micro-payment system is considered to be a service intensive activity, where many payment tasks involve different forms of services, such as payment method selection for buyers, security support software, product price comparison, etc. We will use the micro-payment case to discuss and illustrate how the web services approaches support and transform the business process and integration model.

The application of user log for online business environment using content-based Image retrieval system

Over the past few years, inter-query learning has gained much attention in the research and development of content-based image retrieval (CBIR) systems. This is largely due to the capability of inter-query approach to enable learning from the retrieval patterns of previous query sessions. However, much of the research works in this field have been focusing on analyzing image retrieval patterns stored in the database. This is not suitable for a dynamic environment such as the World Wide Web (WWW) where images are constantly added or removed. A better alternative is to use an image's visual features to capture the knowledge gained from the previous query sessions. Based on the previous work (Chung et al., 2006), the aim of this paper is to propose a framework of inter-query learning for the WWW-CBIR systems. Such framework can be extremely useful for those online companies whose core business involves providing multimedia content-based services and products to their customers

Model-driven design of context-aware applications

In many cases, in order to be effective, software applications need to allow sensitivity to context changes. This implies however additional complexity associated with the need for applications’ adaptability (being capable of capturing context, interpreting it and reacting on it). Hence, we envision 3 ‘musts’ that, in combination, are especially relevant to the design of context-aware applications. Firstly, at the business modeling level, it is considered crucial that the different possible context states can be properly captured and modeled, states that correspond to certain desirable behaviors. Secondly, it must be known what are the dependencies between the two, namely between states and behaviors. And finally, what is valid for application design in general, business needs are to be aligned to application solutions. In this work, we address the mentioned challenges, by approaching the notion of context and extending from this perspective a previously proposed business-software alignment approach. We illustrate our achieved results by means of a small example. It is expected that this research contribution will be useful as an additional result concerning the alignment between business modeling and software design

AtomServ architecture: Towards internet-scaled service, publish, subscription, and discovery

With the surge of SOA-based infrastructure and applications, increasingly end users and small-medium-enterprises directly participate in the service publish and discovery across the Internet. The recent shutdown of public UDDI exposes critical problems of existing Internet-based service discovery. Hence, public service discovery becomes a central SOA issue. In this paper, we present a light weight service discovery architecture built upon widely-adopted WWW technologies and proven software architectural styles. Firstly, it provides a handy discovery facility for personal web services providers and consumers, who would not be expected to able to use complex UDDI specifications with dedicated endpoint computing capability. Secondly, it widens the adoption of service discovery by allowing simple and uniform web user interfaces (e.g. Internet Explorer7.0 and Firefox1.1) to subscribe and access frequently changing business services. This undoubtedly lowers the entry barrier for end users to play the role of service providers or consumers in a sheer Service-Oriented Environment across the Internet

A Framework for Agile Development of Component-Based Applications

Agile development processes and component-based software architectures are two software engineering approaches that contribute to enable the rapid building and evolution of applications. Nevertheless, few approaches have proposed a framework to combine agile and component-based development, allowing an application to be tested throughout the entire development cycle. To address this problematic, we have built CALICO, a model-based framework that allows applications to be safely developed in an iterative and incremental manner. The CALICO approach relies on the synchronization of a model view, which specifies the application properties, and a runtime view, which contains the application in its execution context. Tests on the application specifications that require values only known at runtime, are automatically integrated by CALICO into the running application, and the captured needed values are reified at execution time to resume the tests and inform the architect of potential problems. Any modification at the model level that does not introduce new errors is automatically propagated to the running system, allowing the safe evolution of the application. In this paper, we illustrate the CALICO development process with a concrete example and provide information on the current implementation of our framework
