“…They identified trust and reputation as playing a vital role to enable widespread usage of the multimedia applications. Recent researchers [5,6,10] presented solutions to resolve the trust issue in multimedia and e-services utilizing ad-hoc ubiquitous environments. Their aim is to facilitate and empower the potential benefits of various ubiquitous multimedia applications and to makes it possible for peers to collaborate in a trustworthy environment.…”

One of the significant characteristics of ubiquitous environments is the need for trust management due to the vital role trust plays in the success of such environments. Recommenders constitute an important component for managing trust because they can corrupt the recommendation network by providing bogus feedback resulting in losing transactions with trustworthy nodes and committing transactions with untrustworthy nodes. Honesty checking schemes, assume that a recommender is consistent and thus does not change its recommendation behavior. In this paper, we shed light on the inconsistent recommenders' behavior. That is, recommenders change their recommendation strategy. To the best of our knowledge, this is the first attempt at linking the behavior change to honesty checking. We propose a new honesty checking algorithm and show through extensive simulation experiments its performance compared to existing honesty checking algorithms.

Ubiquitous e-service is one of the most recent links in the chain of evolution that has characterized the different eras of the internetworking environment. In order to leap the trust barrier for the users to embrace these ubiquitous e-services, we present a collaborative iTrust e-service for exploring proximal collective wisdom in the ad-hoc ubiquitous environment. By highlighting the homophily of e-service participants, these isolated individuals can be treated as a group with proximity. Proximity thus enables ad-hoc e-service participants to contribute their strength for ubiquitous collective wisdom. Simulation outcomes for trust decision quality enhancement show significant improvement over traditional designs. The iTrust e-service makes it possible for users to collaborate with the nearby user groups for establishing a reliable and trustworthy interaction environment. It also facilitates and empowers the potential benefits of various ubiquitous e-service applications.Keywords Ubiquitous e-service . Trust . Proximal collective wisdom . Ad-Hoc ubiquitous environment 1 Challenges for ubiquitous trustworthy e-Service Current e-service applications focus more on centralized control aspect, where long-term historical data are collected and top-down design architectures are used to guarantee information service quality of e-service applications. Since Mark Weiser (1991) termed 'ubiquitous' as a new paradigm for computing in 1988, efforts have been concerted to develop and advance information technologies towards 'connecting, invisible calm and silent, and real' ubiquitous computing. The rapid growth of information systems technologies and networking has generated significant opportunities for streamlining decision-making processes and maximizing productivity through distributed collaborations. Emerging collaborative environments need to provide efficient support for seamless integration of heterogeneous technologies such as mobile devices and infrastructures, web services, grid computing systems, various operating environments, and diverse products. Such heterogeneity introduces, however, significant security and privacy challenges for distributed collaborative applications. In such a loosely-coupled open computing system, trust management has become essential, together with traditional cryptography techniques, for building a healthy collaboration among participating peers (or agents). Hence, ensuring trust in an ubiquitous environment is one of the most important tasks of the new networking paradigm. Recent work (McKnight and Chervany 2002) suggests that reputation based trust systems as an effective way for nodes to identify and avoid malicious nodes in order to minimize the threat and protect the system from possible misuses and abuses by malicious nodes in a decentralized overlay networks. Such systems typically assign each node a trust value based on the transactions it has performed with others and the feedbacks it has received.

“…The UPS highlights the collective effort focused on collecting the user group's power as the reference for ubiquitous trust decisions. Some security design was elaborated in Hwang and Yuan (2007), including three conceptual methodology designs: the privacy design, reputation management design, and trust management design. But in is paper we focus on the theoretical support of proximity value.…”

Purpose -The authors seek to propose the notion of ubiquitous proximity e-service for exploring collective wisdom in the ubiquitous environment. Ubiquitous proximity e-service highlights the collective effort focused on collecting the user group's power as the reference for ubiquitous trust decisions. Design/methodology/approach -This paper provides some theoretical utility support for ubiquitous proximity e-service. The "homophily" describes the tendency of individuals to associate and bond with similar others. By highlighting the "homophily" of e-service participants, these isolated individuals can be treated as a group with proximity. The main value of ubiquitous proximity e-service utilizes the network effect from the collective effort of interpersonal social network. Findings -In order to leap the trust barrier for users to embrace these ubiquitous e-services, ubiquitous proximity e-service makes it possible for users to collaborate with their nearby user groups to establish a reliable and trustworthy interaction environment. The simulation outcomes for trust decision quality enhancement show a significant improvement in a variety of environment settings. Practical implications -A significant value of ubiquitous proximity e-service lies in the increased possibility of establishing innovative social network relationships. From the interpersonal perspective, unfamiliar strangers can make connections with individuals who are proximal and homoplastic to them. The strength of proximity gives people better chances to make interpersonal connections, including both weak ties and strong ties. By combining those interpersonal tie relationships, ubiquitous proximity e-service can easily cause information diffusion and effectively encourage collective wisdom. Originality/value -The paper advocates the utility of ubiquitous proximity e-service that can be realized in the e-commerce environment and which enables information diffusion effectively.
