AmbieSense: a system and reference architecture for personalised and context-sensitive information services for mobile users

The purpose of AmbieSense is to provide personalised, context-sensitive information to the mobile user. It is about augmenting digital information to physical objects, rooms, and areas. The aim is to provide relevant information to the right user and situation. Digital content is distributed from the surroundings and onto your mobile phone. An ambient information environment is provided by a combination of context tag technology, a software platform to manage and deliver the information, and personal computing devices to which the information is served. This paper describes how the AmbieSense reference architecture has been defined and used in order to deliver information to the mobile citizen at the right time, place and situation. Information is provided via specialist content providers. The application area addresses the information needs of travellers and tourists

Approaches Regarding Business Logic Modeling in Service Oriented Architecture

As part of the Service Oriented Computing (SOC), Service Oriented Architecture (SOA) is a technology that has been developing for almost a decade and during this time there have been published many studies, papers and surveys that are referring to the advantages of projects using it. In this article we discuss some ways of using SOA in the business environment, as a result of the need to reengineer the internal business processes with the scope of moving forward towards providing and using standardized services and achieving enterprise interoperability.Business Rules, Business Processes, SOA, BPM, BRM, Semantic Web, Semantic Interoperability

Mediated data integration and transformation for web service-based software architectures

Service-oriented architecture using XML-based web services has been widely accepted by many organisations as the standard infrastructure to integrate heterogeneous and autonomous data sources. As a result, many Web service providers are built up on top of the data sources to share the data by supporting provided and required interfaces and methods of data access in a unified manner. In the context of data integration, problems arise when Web services are assembled to deliver an integrated view of data, adaptable to the specific needs of individual clients and providers. Traditional approaches of data integration and transformation are not suitable to automate the construction of connectors dedicated to connect selected Web services to render integrated and tailored views of data. We propose a declarative approach that addresses the oftenneglected data integration and adaptivity aspects of serviceoriented architecture

Data integration through service-based mediation for web-enabled information systems

The Web and its underlying platform technologies have often been used to integrate existing software and information systems. Traditional techniques for data representation and transformations between documents are not sufficient to support a flexible and maintainable data integration solution that meets the requirements of modern complex Web-enabled software and information systems. The difficulty arises from the high degree of complexity of data structures, for example in business and technology applications, and from the constant change of data and its representation. In the Web context, where the Web platform is used to integrate different organisations or software systems, additionally the problem of heterogeneity arises. We introduce a specific data integration solution for Web applications such as Web-enabled information systems. Our contribution is an integration technology framework for Web-enabled information systems comprising, firstly, a data integration technique based on the declarative specification of transformation rules and the construction of connectors that handle the integration and, secondly, a mediator architecture based on information services and the constructed connectors to handle the integration process

Policy driven security architectures for eBusiness

The dawning of the twenty-first century and genesis of a new millennium has been extremely kind to technological advance. Industries and society alike have reaped the extreme benefits of technology at its finest. Technological progress has also proven to be extraordinarily beneficial to businesses and their bottom lines when properly employed. The need for automated business logic and functionality has spawned numerous concepts and efforts to capitalize on advanced business requirements. Probably the most popular and revolutionary to date of all initiatives is the advent of eBusiness. A direct descendant of Electronic Data Interchange (EDI), eBusiness has and continues to evolve into more than a phenomenon, but rather a sound component of successful corporations and organizations. The evolution and acceptance of eBusiness has created a ripple effect throughout the technical and business worlds. The promise of this wonderful concept and its accompanying technology has forced companies to completely rethink strategic planning efforts, and to sit up and pay full attention to this ever-growing development. One area that has been extremely affected by the wide spread acceptance of eBusiness and its counterparts are the architectures and infrastructures now utilized to support these efforts. Enterprise architectures that had originally been designed to shield internal business activities from the public eye of the Internet and other domains have been either replaced, redesigned, or melded with new architectural designs that proclaim companies and their offerings to the world, all in a digital atmosphere. This proclamation can be exceptionally lucrative and damaging, all at the same time. The conception of the Internet has without a doubt been the single most important episode in the continuing fairytale and illumination of technological advance. What once was considered the Underground Railroad of information; limited to universities, research groups, and government organizations has become the Autobahn of electronic data, and continues to evolve and transcend barriers and boundaries. The ability to surpass traditional barriers such as geography and distance serves as a definite attraction for organizations to eBusiness, and a tremendous amount of companies are acting upon this attraction. However, the dark side of the Internet is a playground for adversaries such as, but not limited to hackers (crackers), lone criminals, malicious insiders (disgruntled employees), industrial spies, media representatives, organized crime, terrorists, national intelligence organizations, special interest groups, competitors, script kiddies, and infowarriors to name a few. All of these can and should be considered a potential danger while individuals and organizations alike interact via the Internet and private networks as well. Nowhere are the aforementioned dangers as prevalent as they are in the increasingly popular world of e. eBusiness, eCommerce, eMarketPlaces, eAuctions, eSupplyChains, etc., etc.; the list goes on and on. The digitization of data is big business, and organizations are realizing the infinite potential involved with participating in these markets, as well as utilizing it to streamline day-to-day business operations and management. Around the globe scores of innovative, thought-provoking systems are deployed daily to feed upon the e landscape and take advantage of this new and exciting world of prosperity. However, the same factions that make haste to establish an Internet or web-based presence and rush to take advantage of digital data and goods are often the very ones that almost always either forget, simply neglect, or place a low priority on an absolute vital necessity of all e-efforts. Security! Therefore, the intent of this thesis is to examine and introduce methodical approaches to designing and implementing security life cycles that are driven by policy for secure eBusiness architectures. In order to provide the necessary assurance and security needed for eBusiness architectures efficient well thought out life cycles must be employed for security practices. Security, like any other component of Information Technology (IT) is not a hit or miss scenario. It is a continuos and meticulous process that is all encompassing of all veins of an enterprise. In order to design a secure architecture a procedural approach must be taken, so that all threats, vulnerabilities, adversaries, holes, nooks, and crannies are covered. Even after all these things have been addressed there is no such thing as an impenetrable system or infrastructure, especially in a networked environment. Given enough time and resources the strongest of confines can be made as vulnerable as a home PC connected to the Net. This is especially true for those systems that operate over public networks such as the Internet. Therefore, processes and procedures must be introduced, refined and constantly managed to maintain a secure state of operation. This text will illustrate the process of assessing technical environments utilized for eBusiness initiatives and gathering requirements for secure operation. Then taking those requirements and developing a functional security policy to govern over the system. Next, the document will discuss extracting requirements from the actual security policy and using them to create a plan of implementation. Also, during the implementation phase exists several testing and assurance activities that should be addressed. After, the overall implementation is completed and deployed, streamlined processes must be applied and properly managed to ensure that the hardened solution continues to function, as it should. An adequate cycle is much more intensive than described above, and this thesis will provide the detail needed to thoroughly address the concepts described here

TCG based approach for secure management of virtualized platforms: state-of-the-art

There is a strong trend shift in the favor of adopting virtualization to get business benefits. The provisioning of virtualized enterprise resources is one kind of many possible scenarios. Where virtualization promises clear advantages it also poses new security challenges which need to be addressed to gain stakeholders confidence in the dynamics of new environment. One important facet of these challenges is establishing 'Trust' which is a basic primitive for any viable business model. The Trusted computing group (TCG) offers technologies and mechanisms required to establish this trust in the target platforms. Moreover, TCG technologies enable protecting of sensitive data in rest and transit. This report explores the applicability of relevant TCG concepts to virtualize enterprise resources securely for provisioning, establish trust in the target platforms and securely manage these virtualized Trusted Platforms

Integration of Micro-Services in The Industrial Internet Era

The need for integration arises when companies start considering “boundary-less” information flows across a plateau of multiple enterprise information systems. Adding a new application to the system or replacing one of the existing applications requires the establishment of interfaces with a specific software tool for each of them. The classical way to solve this problem in a large-scale organization is to use a central integration platform based on service-oriented architecture (Service-Oriented Architecture (SOA)). In this work, we forecast the increase of granularity of services and application of micro-services to enhance traditional SOA in the prototypes of industrial internet and Web 3.0

Towards Reducing the Complexity of Enterprise Architectures by Identifying Standard Variants Using Variability Mining

For decades, Enterprise Architectures (EAs) of car manufacturers have been constantly evolved to respond to growing requirements. As a consequence, EAs have often reached a very high level of complexity, which leads to problems in adapting EAs to new environmental condi­tions. Such a new condition is, for instance, digitalization of society (e.g., social media, Internet of Things) which has a huge effect on the automotive industry and the grown EA. Resulting changes in complex EAs have long implementation cycles, require enormous communica­tion efforts, and lead to high development costs. To alle­viate these problems, in this paper, we present a concept to reduce the complexity of grown EAs by adapting the Family Mining approach. This approach is originally used to compare block-oriented models, such as MATLAB/Si­mulink models, and to identify commonalities and diffe­rences between these models. In our concept, we utilize the Family Mining approach to analyze the variability of a particular EA and to identify the contained variants. All information about the variability and the variants will be used to derive standard variants representing default so­lutions for different issues. Using these standard variants, the existing EA will be restructured involving economic considerations (e.g., which standard variant yields best benefits under certain circumstances). Hence, applying this concept to a complex EA should allow reducing the complexity of the EA, alleviating related problems and making suitable design decisions for future extensions
