- Konferenzbeitragbibox: A Tangible Approach to Motivating Participation in Public Libraries(Mensch und Computer 2016 - Tagungsband, 2016) Hofmann, Jacqueline; Müller, Jens; Gipp, Bela; Reiterer, HaraldWithin the Library 2.0 model, visitors of public libraries are enabled to actively shape the services of their library. Unlike previous trends, principles of participation and collaboration should be assimilated into the physical space of public libraries instead of being added as an extra layer on top of existing services. We present a set of eight design principles for motivating participatory systems in the Library 2.0 context. Based on these principles, we introduce bibox, a tangible book rating- and recommendation system for public libraries. In an in-the-wild study, we evaluate how our system motivates active participation. We show that the proposed design principles lead to higher levels of engagement from the users of the system within the Library 2.0 context.
- ZeitschriftenartikelOn-chain vs. off-chain storage for supply- and blockchain integration(it - Information Technology: Vol. 60, No. 5-6, 2018) Hepp, Thomas; Sharinghousen, Matthew; Ehret, Philip; Schoenhals, Alexander; Gipp, BelaSupply chains are the basis of most everyday life products. Both data integrity and authenticity of related information have severe implications for quality and safety of end-products. Hence, tamper-proof storage is necessary that prevents unauthorized modifications. We examine peer-reviewed blockchain technologies according to four criteria relevant to supply chains: On-chain storage, off-chain storage, verification cost and secure data sharing. Our evaluation yields an overview of concepts for modeling supply chain processes and points out that on-chain storage is currently not practical.
- ZeitschriftenartikelOriginStamp: A blockchain-backed system for decentralized trusted timestamping(it - Information Technology: Vol. 60, No. 5-6, 2018) Hepp, Thomas; Schoenhals, Alexander; Gondek, Christopher; Gipp, BelaCurrently, timestamps are certified by central timestamping authorities, which have disadvantages of centralization. The concept of the decentralized trusted timestamping (DTT) was developed by Gipp et al. to address these drawbacks. The paper provides insights into the architecture and implementation of a decentralized timestamp service taking the integration of multiple blockchain types into account. Furthermore, the components are introduced and the versatile application scenarios are presented. A future direction of research is the evaluation of blockchain technology and their suitability for timestamping.
