Blockchain has become an irresistible disruptive technology with the potential to innovate businesses. Ignoring it may in itself result in a competitive disadvantage for organisations. Except for its original financial application of cryptocurrency, more applications are being proposed, the most common being supply chain management and e-voting systems. However, less focus is made on information and cybersecurity applications of blockchain, especially from the enterprise perspective. This paper addresses this knowledge gap by exploring blockchain as a use case for identity management in the context of an organisation. The paper gives a comprehensive background aiming at understanding the topic, including understanding whether claims made around it, especially blockchain’s potential to address identity management challenges, are based on facts or just a result of hype. Meta-synthesis was used as a research methodology to summarise the 69 papers selected qualitatively from reputed academic sources. The general trend shows theoretical evidence supporting some of the claims made but not necessarily friendly to the enterprise context. The study reveals a promising but immature state of blockchain, consequently questioning whether adopting blockchain-based distributed identity management in organisations is fully practical. A research model called TOE-BDIDM is proposed to guide further investigation.

Domain Separation

E-voting increasingly gains interest in e-Democracy and e-Government movements. Not only the technical security issues of electronic voting systems are of paramount importance, but also the necessity of following an all-embracing approach is challenging and needs to be addressed. This paper discusses e-voting as being a supreme discipline of e-Government. It introduces an innovative e-voting concept using the Internet as the voting channel. The concept introduced is based on Austrian e-Government elements and the Austrian identity management concept in particular. This paper presents a novel approach of building an e-voting system relying on two core principles: strong end-to-end encryption and stringent identity domain separation.

Antecedents And Consequences

Purpose Grounded in the resource-based view and social exchange theory, the purpose of this paper is to develop a research model that offers a comprehensive understanding of the antecedents and consequences of electronic supply chain management (e-SCM) diffusion. Design/methodology/approach Survey data from 142 managers (in charge of e-SCM projects in their companies) of large Taiwanese firms were collected and used to test the hypotheses using hierarchical moderated regression analysis. Findings The results indicate that information technology deployment capability, operational capability, human resource capability, and knowledge sharing are important antecedents of e-SCM diffusion. In turn, higher levels of e-SCM diffusion lead to greater competitive performance. This study also finds that knowledge sharing plays a moderating role by strengthening the relationship between organizational capabilities (e.g. operational capability and human resource capability) and e-SCM diffusion. Practical implications Managers should recognize that human resource development activities (recruiting, training, and managing valuable e-SCM personnel) are an important source of e-SCM diffusion. Similarly, managers must establish the connection between human resource capabilities and e-SCM diffusion (i.e. “soft-side” e-SCM) such as hiring and retaining skilled e-SCM personnel, training and development for e-SCM personnel, and measuring e-SCM personnel’s global mindset over time. Originality/value Theoretically, this study aims to provide a research model that is capable of understanding the antecedents and consequences of e-SCM diffusion. From the managerial perspective, the findings of this study provide valuable decision guides for practitioners to help them identify and develop firm internal capabilities and social mechanisms that foster e-SCM diffusion.

Ensuring interoperability across different healthcare providers becomes an important issue with a potentially large return on investment (ROI) potential when multiple healthcare providers are collaborating in an e-Health system. In cross-context communications, the same information can be expressed by means of different types or values. This chapter proposes a new architecture for cross-context identity management in the e-Health application domain, aiming to improve interoperability between healthcare providers when context-specific information, such as patients’ identifiers, is transferred from one context to another. Furthermore, an algorithm for issuing and converting context-specific identifiers, based on cryptographic techniques, is presented. How the proposed cross-context interoperability service can be integrated in a real-word e-Health system is explained with a use case scenario.

Purpose Supply chain integration (SCI) is a critical issue in the study of supply chain management in terms of working with partners on business networks to complete tasks, enhance capability and increase performance in a collaborative supply chain process. Thus, this study aims to investigate the influence of SCI and supply chain capability (SCC) on supply chain performance (SCP) which has a positive effect according to the degree of integration (DI) in a supply chain management process. Furthermore, the DI has a direct or indirect impact on how SCI affects SCP. Design/methodology/approach Through a questionnaire-survey, 454 valid responses were collected. This study investigates the relationships between SCI, SCC, SCP and the DI in the Taiwan elevator by using a structured equations model. The DI is considered as a variable for the effect of a moderated mediation in the research model. Findings It was found that SCI, directly and indirectly, affected the SCP in a positive way. In addition, the research model is a partial mediation model and that SCC plays a mediator role and DI also existing a moderated mediating effect in the research model. The indirect effect of SCI on SCP through SCC is stronger at higher levels of DI than at lower levels of DI. Originality/value This is the first study that suggests and empirically tests the moderated mediating impacts of the integration degree on the relationships between SCI, capability and performance with suppliers of the elevator manufacturing supply chain as the business-to-business network cooperation example in Taiwan.

Purpose There is a lot of interest in blockchain in the supply chain and several papers call it a disruptive technology. Existing research, however, is mostly conceptual and focused on use-case development and early pilots. This paper aims to report the findings from a workshop with managers aimed at empirically exploring what adoption rates and focus areas are for blockchain in the supply chain, what drives blockchain in the supply chain applications and what barriers are to the implementation of blockchain in the supply chain. Design/methodology/approach A workshop with managers was organized to empirically explore blockchain adoption levels and focus areas in the supply chain, as well as drivers and barriers of implementation. Findings Workshop participants reported that adoption of blockchain in the supply chain today is very limited but actively considered by many. Drivers for this consideration include achieving greater transparency and visibility, as well as, improving processes and reducing costs. Participants identify many barriers, including a lack of understanding of costs and benefits of blockchain in the supply chain. Interestingly, participants report less concern about the feasibility of the technology implying managerial consideration if progressing beyond the technology and into the potential adoption of it. As a result, participants may be moving beyond the hype surrounding blockchain and giving consideration to the many remaining questions. A working technology does not yet mean that there is a feasible supply chain adoption. As a result, it may be too early to tell whether blockchain will be a disruptive technology. This paper identifies several fruitful areas for further consideration by management and in research. Originality/value As there is little empirical research on blockchain in the supply chain, this paper moves beyond use-case development and the exploration of pilot cases and studies how companies may consider supply chain adoption beyond the pilot and the early development of blockchain. Although only offering an initial exploration, this paper uncovers progress being reported in industry and many areas where further consideration and research can help advance thinking and practice.

The Impact

A system dynamics model was developed with the primary purpose of visualizing the behavior of a supply chain (SC) when it adopts a disruptive technology such as additive manufacturing (AM). The model proposed a dynamic hypothesis that defines the following issue: what is the impact of the AM characteristics and processes in the SC? The model was represented through a causal diagram in thirteen variables related to the SC, organized in two feedback cycles and a data flow diagram, based mainly on the three-essential links of the SC and the order display traceability: supplier–focal manufacturer–distribution Network. Once proposed, the model was validated through the evaluation of extreme conditions and sensitivity analysis. As a result, the dynamic behavior of the variables that condition the chain management was analyzed, evidencing reduction times in production, especially in products that require greater complexity and detail, as well as reductions in inventories and the amount of raw material due to production and storing practices from AM. This model is the starting point for alternative supply chain scenarios through structural operating policies and operating policies in terms of process management.

Electronic voting or e-voting has been used in varying forms since the 1970s with fundamental benefits over paper based systems such as increased efficiency and reduced errors. However, there remain challenges to achieve widespread adoption of such systems especially with respect to improving their resilience against potential faults. Blockchain is a disruptive technology of the current era and promises to improve the overall resilience of e-voting systems. This paper presents an effort to leverage benefits of blockchain such as cryptographic foundations and transparency to achieve an effective scheme for e voting. The proposed scheme conforms to the fundamental requirements for e-voting schemes and achieves end-to-end verifiability. The paper presents details of the proposed e-voting scheme along with its implementation using the Multichain platform. The paper presents in-depth evaluation of the scheme which successfully demonstrates its effectiveness to achieve an end-to-end verifiable e-voting scheme.
