    Open Process Innovation – drawing from the literature on Open Innovation and Business Process Management (BPM) – promotes the study of how to systematically make use of knowledge that lies outside of an organization’s boundaries for process innovation initiatives. Open Innovation has been heavily studied for product innovation, however, process innovation has not yet been researched from such perspective. Against this background, we seek to investigate into variables that impact on the qualities of Open Process Innovation taking the example of the public sector domain. This paper examines how personnel resource scarcity exerts influence on the involvement of i) customers (here citizens and local companies) and ii) consultants (here management and software consultants) in public sector BPM. Our multi-method analysis shows that personnel resource scarcity has consequences for BPM-related collaboration schema as it restricts the involvement of customers. Based on our findings, implications for theory and practice are discussed, including implications for studies on BPM maturity or on business process design. We call for a governance-theory perspective on process innovation as a fundamental basis for understanding and designing the institutions that shape collaboration in open process innovation

    Mind your step! : How profiling location reveals your identity - and how you prepare for it

    Location-based services (LBS) are services that position your mobile phone to provide some context-based service for you. Some of these services – called ‘location tracking’ applications - need frequent updates of the current position to decide whether a service should be initiated. Thus, internet-based systems will continuously collect and process the location in relationship to a personal context of an identified customer. This paper will present the concept of location as part of a person’s identity. I will conceptualize location in information systems and relate it to concepts like privacy, geographical information systems and surveillance. The talk will present how the knowledge of a person's private life and identity can be enhanced with data mining technologies on location profiles and movement patterns. Finally, some first concepts about protecting location information

    A Network-Economic Policy Study of Identity Management Systems and Implications for Security and Privacy Policy

    Solving the problems associated with identity management in the “virtual” world is proving to be one of the keys to full realization of the economic and social benefits of networked information systems. By definition, the virtual world lacks the rich combination of sensory and contextual cues that permit organizations and individual humans interacting in the physical world to reliably identify people and authorize them to engage in certain transactions or access specific resources. Being able to determine who an online user is and what they are authorized to do thus requires an identity management infrastructure. Some of the most vexing problems associated with the Internet (the deluge of spam, the need to regulate access to certain kinds of content, securing networks from intrusion and disruption, problems of inter-jurisdictional law enforcement related to online activities, impediments to the sharing of distributed computing resources) are fundamentally the problems of identity management. And yet, efforts by organizations and governments to solve those problems by producing and consuming identity systems may create serious risks to freedom and privacy. Thus the implementation and maintenance of identity management systems raises important public policy issues. The identity management systems (the IMS-s) often tend to require more information from the consumers than would otherwise be necessary for the authentication purposes. The typical choice being analyzed in IMS is the one between a completely centralized or integrated system (one ID - one password, and a single sign-on) and the one comprising a plethora of (highly) specialized IMS-s (multiple ID-s and passwords). While the centralized system is the most convenient one, it is also likely to require too much personal information about the users, which may infringe on their rights to privacy and which definitely will result in serious damage should this personal information be stolen and/or abused. When more than two IMS-s interconnect (more of a practical side with various types of commercial values), they share the private information with each other, thus increasing consumers’ exposure to possible information misuse. It is thus rather obvious that the public policy plays an important role to maintain the structure of identity management systems ensuring the existence of a sound balance between the authentication requirements and consumers’ rights to privacy. The focus of this paper is on investigating this type of tradeoff by employing a theoretical framework with agents whose utility depends on the amount of private information revealed, and on making policy recommendations related to the issue of interconnection between alternative IMS-s. Our model derives optimal process of interconnection between IMS-s in the simple case of three IMS-s, then generalizing it to the case of more than three firms. The socially optimal outcome of the interconnection process in our model implies encouraging the interconnection between smaller rather than larger IMS-s.Networks; Interconnection; Identity Management; Regulation Policy

    A Decentralised Digital Identity Architecture

    Current architectures to validate, certify, and manage identity are based on centralised, top-down approaches that rely on trusted authorities and third-party operators. We approach the problem of digital identity starting from a human rights perspective, with a primary focus on identity systems in the developed world. We assert that individual persons must be allowed to manage their personal information in a multitude of different ways in different contexts and that to do so, each individual must be able to create multiple unrelated identities. Therefore, we first define a set of fundamental constraints that digital identity systems must satisfy to preserve and promote privacy as required for individual autonomy. With these constraints in mind, we then propose a decentralised, standards-based approach, using a combination of distributed ledger technology and thoughtful regulation, to facilitate many-to-many relationships among providers of key services. Our proposal for digital identity differs from others in its approach to trust in that we do not seek to bind credentials to each other or to a mutually trusted authority to achieve strong non-transferability. Because the system does not implicitly encourage its users to maintain a single aggregated identity that can potentially be constrained or reconstructed against their interests, individuals and organisations are free to embrace the system and share in its benefits.Comment: 30 pages, 10 figures, 3 table

    Surveillance and the Self: Understanding Privacy and Identity in Digital Environments

    The widespread use of internet enabled devices among contemporary US adults has given rise to a series of questions about issues of identity, privacy and group behaviors. The increasing use of algorithmic systems in social media and the attendant privacy concerns among users may also contribute to increased levels of strategic management of identity among users. In order to contribute to this discussion, this project examines perceptions and practices of privacy and self-representation in digital spaces among college age adults 18-24. This project utilizes semi-structured interview data collected with college students in the Eastern United States and focuses on both behavioral and attitudinal patterns. I specifically consider the impact of strategic interventions of corporate media platforms to collect, distribute, manage and utilize individual level data on participants\u27 information consumption, individual identity representation and group affiliation. Preliminary data suggests that participants engage partial and strategic representations of self across diverse media platforms. Patterns of self-representation are shaped by a wide variety of factors including in-group online community norms, perceptions of visibility and privacy, algorithmic distributions of information and individual perceptions of technology. Furthermore, online identity, while partial and strategically created, has the potential to impact self-identity and group affiliation in a diverse set of offline and online contexts

    Risks of identity theft: Can the market protect the payment system?

    Identity theft has been a feature of financial markets for as long as alternatives have existed to cash transactions. But identity theft has recently occurred on a much larger scale. Data breaches often involve the apparent loss or acknowledged theft of the personal identifying information of thousands--or millions--of people. ; Identity theft poses risks, not only to individuals, but to the integrity and efficiency of the payment system--the policies, procedures, and technology that transfer information for authenticating and settling payments among participants. Identity theft can cause a loss of confidence in the security of certain payment methods and an unwillingness to use them. Markets can cease operating or switch to less efficient payment methods. Either represents a loss of efficiency for the economy. ; Schreft looks at the nature of identity theft today and the factors underlying its mounting risks. She also explores whether markets are able to limit the risks identity theft poses to the payment system.Identity theft ; Payment systems

    Government information is a vital asset that must be kept in a trusted environment and efficiently managed by authorised parties. Even though e-Government provides a number of advantages, it also introduces a range of new security risks. Sharing confidential and top-secret information in a secure manner among government sectors tend to be the main element that government agencies look for. Thus, developing an effective methodology is essential and it is a key factor for e-Government success. The proposed e-Government scheme in this paper is a combination of identity-based encryption and biometric technology. This new scheme can effectively improve the security in authentication systems, which provides a reliable identity with a high degree of assurance. In addition, this paper demonstrates the feasibility of using Finite-state machines as a formal method to analyse the proposed protocols
