Abstract: This article raises the level of discourse about the role of concepts in the information systems (IS) field. Concepts are the irreducible and indispensable elements of theory. It is through the invention of new concepts that disciplines are able to navigate uncharted waters. Without new concepts, not only will we be unable to comprehend unprecedented phenomena, we will not be able to tame their less than desirable implications. Concepts are distinguished from constructs, which IS researchers are more familiar with, but which enter the research process too late for any creative theorizing. A brief example of how concepts are defined illustrates the usefulness of concept analysis. Collapse

Abstract: Prior information system research remains inconsistent of the effects of system certifications. In their current use, certifications are often reduced to graphical seals. This approach fails to incorporate detailed assurance information emanating from the certification process. To address this gap, we adopt a design science approach and deploy a four-phase research design to clarify how to design impactful IS certification presentations. First, we identify sources of users' limited understanding of seals and formulate a design proposal for a certification presentation by drawing upon the elaboration likelihood model. In the second phase, we formulate and validate a set of design meta-requirements and guidelines to improve certification presentation, using cognitive load theory and Toulmin's model of argumentation as kernel theories. In the third phase, new certification presentations that comply with the proposed guidelines are developed and evaluated for their effectiveness. We show that presentations that augment seal-based certification presentations with richer assurance information improve certification effectiveness. This increases users' assurance and trust perceptions when the presentations align with the users' cognitive information processing needs in ways that reduce their cognitive load and enhance argument quality of assurance information.

Abstract: Authentication plays an important role in securing our systems but is threatened by increasingly sophisticated account hacking and account take over. Several security services have been developed, including multi-factor authentication (MFA) designed to cope with online account authentication. It remains unknown how users perceive and evaluate secure authentication for online account threats and consequently use it to protect their online account. Drawing on the Protection Motivation Theory (PMT) and the literature on anticipated regret, this study investigates the factors that affect the use of MFA secure authentication to avoid online account threats. This work extends PMT by showing how the emotion of anticipated regret heightens appraisals of threat and coping. Collapse

Abstract: Public auditing and data deduplication are integral considerations in providing efficient and secure cloud storage services. Nevertheless, the traditional data deduplication models that support public auditing can endure the enormous waste of storage and computation resources induced through data redundancy and repeated audit work by multiple tenants on trusted third-party auditor (TPA). In this work, we introduce blockchain-based secure decentralized public auditing in a decentralized cloud storage with an efficient deduplication model. We employ blockchain to take on the task of centralized TPA, which also mitigates the implications of malicious blockchain miners by using the concept of a decentralized autonomous organization (DAO). Specifically, we employ the idea of redactability for blockchain to handle often neglected security issues that would adversely affect the integrity of stored auditing records on blockchain in decentralized auditing models. However, the proposed model also employs an efficient deduplication scheme to attain adequate storage savings while preserving the users from data loss due to duplicate faking attacks. Moreover, the detailed concrete security analysis demonstrates the computational infeasibility of the proposed model against proof-of-ownership, duplicate faking attack (DFA), collusion attack, storage free-riding attack, data privacy, and forgery attack with high efficiency. Finally, the comprehensive performance analysis shows the scalability and feasibility of the proposed model. Collapse

Abstract: Service platforms are becoming dominant drivers of daily business operations in a digitalized environment. Research focuses on technological and network effects of such platforms, while socio-technical opportunities remain limited. Guidance support in selecting appropriate digital services on a multisided market platform may help companies with low domain knowledge as it increases their benefits by reducing existing barriers in adopting emerging technologies. We adapt the concept of a broker to a digital platform, which instantiates guidance support on multisided markets as core platform element. Further, we abstract the concept of a digital broker platform as an Information Systems (IS) design theory. By providing the necessary components of an IS design theory, we offer the possibility to derive digital broker platform artifacts, which are theoretically and conceptually grounded. We provide design principles for the method artifact and describe their applicability in an exemplary instantiation of the design theory in the domain of cloud computing. Lastly, we present the artifact’s mutability as well as its testable propositions. Collapse

Abstract: Phishing is an increasing threat that causes billions in losses and damage to productivity, trade secrets, and reputations each year. This work explores how security gamification techniques can improve phishing reporting. We contextualized the cognitive evaluation theory (CET) as a kernel theory and constructed a prototype phishing reporting system. With three experiments in a simulated work setting, we tested gamification elements of validation, attribution, incentives, and public presentation for improvements in experiential (e.g., motivation) and instrumental outcomes (e.g., hits and false positives) in phishing reporting. Our findings suggest public attribution with rewards and punishments best balance the competing necessities of accuracy with widespread reporting. Furthermore, our results demonstrate the unique benefits of security gamification to phishing reporting over and above other phishing mitigation techniques (e.g., training and warnings). However, we also noted that unintended consequences in false alarms might arise from shifts in motivation resulting from public display of incentives. These findings suggest that carefully calibrated external incentives (rather than intrinsic rewards) are most likely to improve the ancillary task of phishing reporting. Collapse

Abstract: The cloud gaming service (e.g., Google Stadia) is an emerging business that delivers game screen as streamed video to customers through the internet. Customers are endowed with the option of gaming on the cloud or staying with traditional consoles (e.g., Sony PlaySta tion). Hence, it becomes important for both the cloud gaming and console services to ana lyze the decisionmaking process of customers while optimizing their prices. Even though it is becoming an important problem for these service providers, it has not been analyzed rigorously in the literature. In this paper, we attempt to fill this important gap by analyz ing the competition between the cloud gaming and console services in a gametheoretical setting. Our results show that revenues of console service providers are not necessarily hurt if customers' valuation of the strengths of cloud services is higher. Besides, cloud gaming services do not always benefit from a higher percentage of core customers. 1 Traditional vs CloudBased Services AnalysisAmong the different types of cloudbased services, cloud computing and cloud storage markets are compar atively mature, and there have been a few studies in the literature that analyzed those. However, research in cloud gaming market is very rare and the competition of cloud gaming services with traditional services has not been analyzed. Cloud gaming is different with other cloud services in terms of targeting customers, competition situation, and so on. Thus, the model is very different. Our paper mainly focus on cloud gaming as one type of cloudbased services to address the critical gap. MotivationCloud gaming services target on tripleA (or AAA) games players. TripleA games are ones that require high budget, involve considerable teams working for months or years, of high quality, and designed to be blockbusters (Vicente 2020). Although customers always have preference on some games over the others, all tripleA games have their own groups of fans. These games require high performance devices to run. Cloud gaming services allow customers to run tripleA games on servers rather than on their own devices, so that people do not need to purchase their own high performance devices, which are consoles. Games that are optimized for lowend devices are out of our consideration, because these games do not need to be run on servers. Cloud gaming services do not include lowend games in their libraries. For console providers, they also build highperformance consoles targeting tripleA games. Therefore, cloud gaming service providers and console providers compete directly.Comparing with console gaming, the biggest benefit cloud gaming brings about is the flexibility and conve nience (Hoffman 2016). On the one hand, as mentioned in the former paragraph, cloud gaming frees the hardware requirement on consumers. With a portable lowend device, customers can be more flexible. They can play games at any places besides home. As a lowend device is usually light and small, customers can even game on the go. Besides, instead of gathering at a console owner's home, people can gather at any place to play games together. In general, cloud gaming eliminates the spatial restriction on where people can play games. On the other hand, games running on the cloud brings convenience to customers. They do not need to worry anything related to the software, such as downloading, updating, and compatibility issues. The cloud gaming service providers would make everything ready. Storage of the local hard disk is also no longer a limitation of how many games people can play. Collapse

Abstract: Cloud brokers are intermediaries supporting the evaluation, selection, and implementation of cloud services. Especially small and medium-sized enterprises with limited technical competencies struggle with a complex and non-transparent market, selecting and combining services from different cloud service providers. They need guidance in the pre-adoption phase to successfully handle selection decisions. Using decisional guidance theory, we have designed a cloud broker platform that aims to provide such guidance. The results of its evaluation show how such a platform improves selection decisions by reducing complexity and structuring the selection process. They also show that the platform's usefulness may be limited in the case of very complex cloud services depending, for example, on the degree of customization needs. Our study provides design knowledge for decisional guidance (in the context of cloud broker platforms) and shows how cloud service selection can be implemented in practice. Collapse

Abstract: Video -on-demand (VoD) services attract millions of subscribers around the globe. Despite their popularity, practice shows the interesting behavior of subscribers of VoD services switching regularly between different providers, such as Netflix or Amazon Prime Video. To sustain their revenues due to subscriptions, providers need to understand the reasons why subscribers switched to other VoD services. While existing research with a prospective point of view explains that users develop switching intentions between different services because of, for instance, dissatisfaction, there is scant research on their actual switching behavior from a retrospective. By analyzing interviews with 23 subscribers that switched VoD services, findings reveal five switching causes and three switching barriers that together explain switching behavior between VoD services. With that, the findings contribute to switching research by identifying switching causes and switching barriers, zooming in on causes of subscribers' dissatisfaction with VoD services, and studying switching behavior from a retrospective.

Abstract: The success of platform companies often depends on their ability to “scale” their customer and supplier base. Existing studies have focused on a variety of approaches that platforms may use to scale but have not systematically considered that platforms might acquire other companies as part of this growth strategy. In this paper, we study the acquisition patterns of digital platform companies and contrast these with the acquisition patterns of digital non-platform companies. We find that platform companies acquire earlier (shortly after founding) when compared with non-platform companies, and they often first acquire competing platform companies from the same market niche. As platform companies mature, they begin to acquire non-platform companies from other market niches. This contrasts with how acquisitions are made by non-platform companies, as shown in our analysis.
