- KonferenzbeitragAdapting RDMO for the Efficient Management of Educational Research Data(21. Fachtagung Bildungstechnologien (DELFI), 2023) Kiesler, Natalie; Schiffner, Daniel; Nieder-Vahrenholz, AxelResearch data management has become a core element of research projects in educational technology research. Tools like the Research Data Management Organiser (RDMO) offer support to researchers by gathering metadata of (planned) projects, studies and their output in a structured manner. It further facilitates machine actionable components so that metadata and information can be exchanged by connecting metadata, repositories, and institutions. In this demo, we present a use case of RDMO at a German research data center. Therein, we adapt RDMO’s export plugin so that it generates JSON in the data structure of the German Network of Educational Research Data, and thus allows the export of metadata from RDMO to research data centers. This proof-of-concept thus presents an application scenario of RDMO, and how it can contribute to an improved data management process in educational technology research.
- TextdokumentBenchmarking Fingerprint Minutiae Extractors(BIOSIG 2017, 2017) Chugh,Tarang; Arora,Sunpreet S.; Jain, Anil K.; Paulter Jr.,Nicholas G.The performance of a fingerprint recognition system hinges on the errors introduced in each of its modules: image acquisition, preprocessing, feature extraction, and matching. One of the most critical and fundamental steps in fingerprint recognition is robust and accurate minutiae extraction. Hence we conduct a repeatable and controlled evaluation of one open-source and three commercial-off-the-shelf (COTS) minutiae extractors in terms of their performance in minutiae detection and localization. We also evaluate their robustness against controlled levels of image degradations introduced in the fingerprint images. Experiments were conducted on (i) a total of 3;458 fingerprint images from five public-domain databases, and (ii) 40;000 synthetically generated fingerprint images. The contributions of this study include: (i) a benchmark for minutiae extractors and minutiae interoperability, and (ii) robustness of minutiae extractors against image degradations.
- KonferenzbeitragCombination of x509 and DID/VC for inheritance properties of trust in digital identities(Open Identity Summit 2022, 2022) Bastian, Paul; Stöcker, Carsten; Schwalm, SteffenThe proposal for review of the eIDAS Regulation from 2021 has opened strong expectations for a deep change in traditional identity models. The user-centric identity model proposed starts with the creation of European Digital Identity Wallets that will enable citizens’ control over their data in identification and authentication processes without control by entities providing the identification services. Likewise digital identities and digital signatures are in place and interoperability between existing solutions mainly based on x509 certificates and decentralized PKI using DID/VC foreseeable. The paper provides various options to address different aspects in combining x509 and DID/VC approaches.
- KonferenzbeitragCoordinating Interdependent E-Government Solutions Illustrated on the Electronic Change of Address in Switzerland(Electronic Government and Electronic Participation - Joint Proceedings of Ongoing Research of IFIP EGOV and IFIP ePart 2018, 2013) Selzam, Thomas; Neuroni, Alessia C.; Riedl, ReinhardIn this case study we illustrate the high complexity of a rather simple inter-agency e-government service: change of address in Switzerland. This enables us to identify typical sources and dimensions of complexity for inter-agency services in countries with decentralised competencies among government agencies. From the resulting picture we draw conclusions on how to deal with complexity - and how to avoid further dramatic increases of e-government complexity. In particular, we discuss the role of coordination of e-government service development projects plays in the fight against exploding complexity.
- KonferenzbeitragDerivation of Categories for Interoperability of Blockchain- and Distributed Ledger Systems(INFORMATIK 2019: 50 Jahre Gesellschaft für Informatik – Informatik für Gesellschaft, 2019) Zeuch, Katharina; Wöhnert, Kai Hendrik; Skwarek, VolkerDue to increasing security requirements e. g. for transaction based smart-x-technologies in distributed systems, blockchain technologies are predestined for secure data exchange and keeping in distributed systems. Although the underlying principle of almost every blockchain is the Byzantine fault tolerance (BFT), its implementation differs significantly between the technologies so that migration or interoperability between systems is nearly impossible. Additionally, this missing interoperability also reduces the chance for scalability between different extents of implementation as there is usually not a one-size-fits-all-blockchain: Different technologies have their advantages for different systems. Therefore scalability and interoperability are tightly coupled. As a basis for further research on and the derivation of generally scalable and interoperable architectures of blockchains, current technologies have to be made comparable and interoperability criteria have to be developed. This paper analyses current literature and introduces technical criteria for the comparison of blockchainand distributed ledger technologies (BC/DLT).With a list of eleven criteria popular BC/DLTs such as Bitcoin, Ethereum, Hyperledger Fabric, Ripple and Corda are compared regarding general features.
- ZeitschriftenartikelDie Innovationstätigkeit der deutschen Softwareindustrie(Wirtschaftsinformatik: Vol. 44, No. 2, 2002) Friedewald, Michael; Blind, Knut; Edler, JakobIn this article we present the results of two empirical studies focusing on the structure and extent of the innovation activities of the German Software Industry and analyze distinctive features of Software Innovations. We distinguish the activities of the primary (core) Software Industry and secondary industries such as Mechanical and Electrical Engineering, Motor Industry and Telecommunications. A special focus is put on the question if innovations in Software are sequential, on the role of Open Source Software and the importance of interoperability.
- KonferenzbeitragFarmBot-based-ISOBUS demonstrator for research and teaching(43. GIL-Jahrestagung, Resiliente Agri-Food-Systeme, 2023) Phillips, Frederick John; Favier, Marc-Alexandre; Dörr, JörgWith the rise of digitalization in today’s agriculture, it is becoming increasingly important to integrate modern technology, like ISOBUS, in both research and education. That’s why a certain number of products such as Hardware-in-the-Loop and physics-engine based simulators or small scale ISOBUS demonstrators have already been developed in the past [Fa20]. Still, Researchers and students have limited options to interact with this type of system. Combining ISOBUS with an open-source farming robot called FarmBot represents a unique opportunity to work and teach with a small-scale local setup. To this end, a demonstrator was created that integrates a university FarmBot with an actual tractor terminal. The demonstrator’s software controls and tracks the FarmBot’s movements. Written in Python, it features robust compatibility and expandability. The hardware component connects this software to the ISOBUS terminal. A simple attachment setup mimics a tractor implement and displays advanced ISOBUS functions. Section Control and Variable Rate Application are of two these functions accurately incorporated by the developed tool. This system allows for a customizable demonstrator on university grounds, enabling students and researchers to work and learn with industry-standard implements.
- TextdokumentFeature-based Comparison of Open Source OPC-UA Implementations(INFORMATIK 2020, 2021) Mühlbauer, Nikolas; Kirdan, Erkin; Pahl, Marc-Oliver; Waedt, KarlOPC UA is an industry-standard architecture for automation, process controlling and monitoring. It is a detailed and complex machine-to-machine communication protocol which makes it challenging to implement. The complexity of the protocol leads to heterogeneity among implementations. Today, there are several open-source implementations without a compliance certificate accredited by the OPC Foundation. Certified implementations undergo various tests to fulfil interoperability. Every implementation fits different use-cases and requirements as each of them comes with its own features. In this paper, we make a feature-based comparison of the most common open-source OPC UA implementations. We investigate their support for the essential features and functionalities. Furthermore, we evaluate their interoperability. Overall, our study shows that open-source implementations have good coverage of features and functionalities, especially open62541 and UA-.NETStandard. Furthermore, our tests show that they do not have any significant interoperability issue.
- KonferenzbeitragA Human Digital Twin as Building Block of Open Identity Management for the Internet of Things(Open Identity Summit 2020, 2020) Zibuschka, Jan; Ruff, Christopher; Horch, Andrea; Roßnagel, HeikoIn networked industry, digital twins aggregate product data along the entire life cycle, from design and production to deployment. This enables interoperability between different data sources and analysis functions and creates an integrated data environment. Human digital twins have the potential to create a similarly interoperable and integrated data environment for more user-centric use cases in the field of the Internet of Things. In this case, personal data is processed and transmitted; therefore, the underlying infrastructure is then not product data management but identity management. In this paper, we discuss general aspects of the human digital twin, its role in open identity management systems, and illustrate its application in the field of home, building and office automation. We identify advantages and limitations and suggest future research opportunities.
- KonferenzbeitragAn idea of using Digital Twin to perform the functional safety and cybersecurity analysis(INFORMATIK 2019: 50 Jahre Gesellschaft für Informatik – Informatik für Gesellschaft (Workshop-Beiträge), 2019) Lou, Xinxin; Guo, Yun; Gao, Yuan; Waedt, Karl; Parekh, MithilCurrent power plants, including nuclear power plants are based on digital technology. According to the Industry 4.0 concepts, similarly to the intelligent manufacturing for new factories, the use of digital twins for power plants is expected to progress. Researchers do the safety and cybersecurity analysis from various perspectives utilize different approaches, e.g. on the safety side, the FMEA (Failure Mode & Effect Analysis), FMECA (Failure mode, Effects and Criticality Analysis) are recommended by FAA (Federal Aviation Administration) to do the reliability analysis. On the cybersecurity part, researchers do the analysis only with a focus on the communication protocol, the code/memory level or on the system functionality. We have addressed refueling machines as an example for the joint consideration of functional safety and cybersecurity in previous publications. Whereas in this paper, we propose to do a functionality and cybersecurity analysis based on the digital twin of an ICS (Industrial Control System). We take the refueling machine as an example and discuss how to twin the refueling machine with high detail firstly. In addition, the possible way of how to model the ICS is discussed, e.g. the Automation ML will be used to describe the system, the OPC UA will be applied to implement the communication. Then the feasibility and benefit of analyzing the system functionality and cybersecurity based on the digital twin model are discussed.
