A Trust Value Sharing Scheme in Heterogeneous Identity Federation Topologies

Recent developments in heterogeneous identity federation systems have heightened the need for the related trust management system. The trust management system evaluates, manages, and shares users’ trust values. The service provider (SP) members of the federation system rely on users’ trust values to determine which type and quality of service will be provided to the users. While identity federation systems have the potential to help federated users save time and energy and improve service experience, the benefits also come with significant privacy risks. So far, there has been little discussion about the privacy protection of users in heterogeneous identity federation systems. In this paper, we propose a trust value sharing scheme based on a proxy ring signature for the trust management system in heterogeneous identity federation topologies. The ring signature schemes can ensure the validity of the data and hide the original signer, thereby protecting privacy. Moreover, no group manager participating in the ring signature, which naturally matches with our decentralized heterogeneous identity federation topologies. The proxy signature can reduce the workload of the private key owner. The proposed scheme shortens the calculation time for verifying the signature and then reduces the overall time consumption in the process of trust sharing. Our studies prove that the proposed scheme is privacy-preserving, efficient, and effective.

Relational governance and opportunism in logistics outsourcing relationships: empirical evidence from China

Logistics outsourcing is prevalent in today's business world as a strategy to obtain competitive advantages. As in other relational exchanges, it is imperative to understand how to alleviate opportunistic behaviour in logistics outsourcing relationships. Using China's burgeoning logistics industry as a backdrop, and drawing on social exchange and transaction cost theories, this study examines how relational norms and trust mitigate opportunistic behaviour and how environmental uncertainty moderates the effects of norms and trust from logistics users’ perspective. Employing data collected from 119 manufacturing and service firms in China, we empirically test the proposed model and find that trust and norms are effective safeguards in reducing the opportunistic behaviour of logistics service providers, particularly in highly uncertain environments.

Characterizing Chinese consumers’ intention to use live e-commerce shopping

Live e-commerce shopping has attracted widespread attention in the global market, and China is the markets with the most active users. Despite the exponential growth of live e-commerce shopping, there are still challenges to understand the customer psychological determination mechanism. We proposed an extended theoretical model from the Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) and performed a cross-sectional survey of the e-commerce consumers. In total, 972 valid responses were collected from four cities in mainland China. Structural equation modeling was used to investigate the factors that influence consumers to adopt live e-commerce shopping. The empirical results confirm the theoretical model explains 78.5% of participants’ behavioral intention and 79.2% of use behavior. Performance expectancy (β = 0.325), effort expectancy (β = 0.202), facilitating conditions (β = 0.097), hedonic motivation (β = 0.213), habit (β = 0.228), and trust (β = 0.218) are significantly related with behavioral intention, while social influence (β = −0.036) and price value (β = 0.022) are not significant factors. Facilitating conditions (β = 0.206), habit (β = 0.203), trust (β = 0.392), and behavioral intention (β = 0.317) are the significant determinants of use behavior toward live e-commerce shopping. Four demographic variables, including gender, age, education, and income, release the significant moderating effects in the theoretical model. This research helps e-commerce platforms and retail stores develop effective strategies to activate consumers' adoption of live e-commerce shopping.

Influence of power and trust on the intention to adopt electronic supply chain management in China

Electronic supply chain management (eSCM) has become a popular Web-based seamless supply chain process. Given that Chinese firms are important parts of global supply chains, it is imperative to investigate factors that would affect eSCM adoption in China. In this study, we examine the impact of three power sources – non-mediated, coercive-mediated and reward-mediated power – on the three dimensions of trust – competence, goodwill and contractual – and their influence in turn on a firm’s eSCM adoption intention in China. We collected data through a survey of 131 manufacturing and service firms in China. Our results show that non-mediated power is positively associated with competence and goodwill trust but negatively related to contractual trust. Coercive-mediated power only negatively affects competence and goodwill trust. Reward-mediated power does not affect any type of trust significantly. The results also provide empirical support for the positive effects of competence and contractual trust on the intention to adopt eSCM. This paper contributes knowledge about the power–trust relationship in China from a supply chain perspective and presents a multi-dimensional explanation of the relationships between power, trust and intention to adopt eSCM.

Co-evolution between streaming and live music leads a way to the sustainable growth of music industry – Lessons from the US experiences

While digitization of music, particularly streaming services, has gained increasing popularity, it has also led to a steady decline in the revenues of recorded music industry. This is causing strong concern regarding a potential collapse of the music industry comparable to other print media industries such as newspaper and book publishing.However, recent changes in the music industry initiated by a resurgence of the live music industry are giving rise to some expectations for the survival and growth of the music industry. The parallel paths of increasing popularity of streaming services and a resurgence of live music suggest that these two dynamics are working together in a co-evolutionary way toward the sustainability of the music industry.This paper attempts to elucidate the co-evolutionary dynamism between the increasing popularity of streaming music and the resurgence of live music.An empirical analysis of monthly trends over the period of the last three decades in the US music industry by its sectors revealed that (i) the co-evolution between streaming and live music industries has functioned well over the last few years, (ii) the live music industry has incorporated a self-propagating function by assimilating innovations previously initiated by digital music, (iii) given the above co-evolution, the recent resurging trend in the music industry can be sustained, (iv) the advancement of digital innovations such as artificial intelligence, machine learning, fintech, virtual reality, big data, and social media by enabling such coevolution have transformed the live music industry into a “live-concert-streaming music industry” (LCSMI) that further enabling the participative creativity of its stakeholders. For these collaborative and cultural industries to function in harmony, trust between its participating stakeholders is very crucial.This analysis suggests the significance of a trust-based ICT-driven disruptive business model (IDBM) with a consolidated challenge for social demand (CCSD) for the development of cultural industries.

Mobile Internet Mobile Agent System Dynamic Trust Model for Cloud Computing

In mobile cloud computing, trust is a very important parameter in mobile cloud computing security because data storage and data processing are performed remotely in the cloud. Aiming at the security and trust management of mobile agent system in mobile cloud computing environment, the Human Trust Mechanism (HTM) is used to study the subjective trust formation, trust propagation and trust evolution law, and the subjective trust dynamic management algorithm (MASTM) is proposed. Based on the interaction experience between the mobile agent and the execution host and the third-party recommendation information to collect the basic trust data, the public trust host selection algorithm is given. The isolated malicious host algorithm and the integrated trust degree calculation algorithm realize the function of selecting the trusted cluster and isolating the malicious host, so as to enhance the security interaction between the mobile agent and the host. Given algorithm simulation and verification were carried out to prove its feasibility and effectiveness.

A Hierarchical Trust Model for Peer-to-Peer Networks

Trust has become an increasingly important issue given society’s growing reliance on electronic transactions. Peer-to-peer (P2P) networks are among the main electronic transaction environments affected by trust issues due to the freedom and anonymity of peers (users) and the inherent openness of these networks. A malicious peer can easily join a P2P network and abuse its peers and resources, resulting in a large-scale failure that might shut down the entire network. Therefore, a plethora of researchers have proposed trust management systems to mitigate the impact of the problem. However, due to the problem’s scale and complexity, more research is necessary. The algorithm proposed here, HierarchTrust, attempts to create a more reliable environment in which the selection of a peer provider of a file or other resource is based on several trust values represented in hierarchical form. The values at the top of the hierarchical form are more trusted than those at the lower end of the hierarchy. Trust, in HierarchTrust, is generally calculated based on the standard deviation. Evaluation via simulation showed that HierarchTrust produced a better success rate than the well-established EigenTrust algorithm.

Trust management for e-transactions

There has been enormous increase in transactions and cooperative-computing services on the internet. This is both a technical and a social phenomenon. Transactions and services over the internet have global reach and users, known or unknown to the service provider, might be interested in availing access or participating in the cooperative transaction in a distributed manner. Thus, it is very important for service providers to identify and establish trustworthiness of potential collaborators, which they do by writing contracts (e.g. access control, security policies; the words contract and policy are used interchangeably) without violating the privacy and confidentiality laws that prevail across geographical boundaries. But as the system becomes complex and dynamic, contractual incompleteness arises since it becomes cumbersome to mention potentially large set of outcomes of the user's choice of action. Trust plays a crucial role in the design of optimal contracts; not all the relevant, valuable information on the user's choice of action is incorporated in the equilibrium contract. It may also be noted in that traditional transactions, the notion ofseeing is believing plays a vital role. However, in e-transactions, this is not the case. The challenge is to see how in such a scenario trust can indeed be generated. Note that the presence of trust facilitates cooperative behaviour and allows for exchange to occur in situations where its absence would preclude trade. In this paper, we shall present a comparative analysis of various approaches of trust management in practice that integrates technology with other factors. We shall also bring out the relative deficiencies and how these issues are tackled in our ongoing work that facilitates execution of optimal contracts.
