Trust is risky. If the two sides is not enough high trust, or is asymmetirc in trust each other, it is easy totrigger a trust crisis, and which bring risks to the supply chain and its members. The guarantee mechanism of trust can manage and control trust risk. The paper firstly introduces the risk under the supply chain environment, analyses the risk of trust. Then, it analyzes the trust insurance mechanism based on the system constraints by using the game theory, as well as the insufficiency of system restraints.

The purpose of this study is to investigate corporate governance which divided in system and operation part through trust mechanism. Trust mechanism models are consist of governance, stakeholder and corporate domains, Trust are conceptualized by two constructs: risk and interdependence. For the trust mechanism, we make four types trust typology: high risk - high interdependence(relational-based trust), high risk - low interdependence(transitional - based trust), low risk - high interdependence(balance - based trust) and low risk - low interdependence(calculus-based trust). We suggest that trust mechanism affect to corporate governance - system and operation part - to reduce corporate governance critical problems and in addition, trust mechanism are not static but dynamic process to desirable path to balance-based trust. system part role is to impact on decision making and operation part role is to reduce organizational control cost.

The role of trust in online open marketplace is more important than that in Internet shopping malls because the risk resulting from opportunistic actions is high. Trust in Internet shopping is classified into seller trust and institution-based trust(e.g. third-party escrows, feedback mechanism, real name systems and three strikes out) which is called web site trust. Institution-based trust can be transferred to seller trust. Especially feedback mechanisms act as reputation systems, informing buyers about a seller's reputation and creating price premiums for trustworthy sellers returns to their reputation. Prices are as important as confidence in the online open marketplace. Lower price than Internet shopping malls provides consumers with motivation of purchase from open marketplaces. Although many studies on the trust have been conducted, there are only a few works considering together trust and price in electronic commerce. Thus. It is important to conduct the study on the relationship between seller trust and price premium in online open marketplaces. The purpose of this study is to answer the following two research questions based on price premium, buyer's motivation participating into open marketplaces, trust transfer. and price thresholds. How do buyer consider the relationship between trust and price in case of decision making for purchasing in online open marketplace? Does seller trust have ap influence on price premium in online open marketplace? Five hypotheses are derived from the above research questions and are tested. In this paper, we proposed a objective and scientific method for calculating seller trust by employing real data of seller ratings given in online marketplace. The new method is called a seller trust function. Auctiontwww.auction.co.kr) known as the largest and oldest open marketplace in Korea is selected for driving a seller trust function and for testing hypotheses. All sellers of Auction site have seller trust indicators including seller grade. selling satisfaction. and seller rating/product rating. A total of 252 valid samples were collected from questionnaire survey in which buyers of Auction were asked to assess importance of three seller trust indicators and to offer trust levels of each seller trust indicator as shown in Appendix 1. We calculated weights of three seller trust indicators by applying analytical hierarchy process (AHP) to the sample data. To answer the questions. rating information of 167 sellers and price data for 4 product items form Auction site were gathered. To test research hypotheses. correlation analysis and multiple regression technique were used. In this study. we have shown that seller trust is positively associated with price in case (of higher price products while no such correlation exists in case of lower price products. In case of higher price products over 450 US dollars. seller trust had a significant impact on price premium. However. seller trust had no influence on price premium in case of lower price products below 70 US dollars. Hierarchical regression analysis showed that price played a moderating role in the relationship between seller trust and price premium. We found that purchase decision making depends on factors except seller trust and price such as convenience or timeliness in case of lower price products if buyers assure that the open marketplace with good institution-based trust is reliable. By using the real transaction data provided by open marketplace. the paper has theoretical and practical implications fer better understanding the role of seller trust on forming the price premium in online marketplaces.

This study focuses on live commerce based on the TaoBao live streaming shopping platform which is a fast-growing electronic(e-) commerce area, along with the spread of live streaming services. Live commerce refers to a new type of commerce which combines electronic commerce with live streaming. Drawing on the literature of consumer trust and trust transfer in e-commerce, this study examines how to increase global consumers’ purchase intentions of domestic products with a low level of brand awareness through live commerce. By considering platform trust, seller trust, and product trust as consumer trust, this study explores the effect of trust transfer among them. Moreover, this study investigates key determinants of consumer trust in live streaming shopping. The partial least squares (PLS) analysis with a total of 200 data collected on buyers with experience in TaoBao live streaming shopping. The key findings are presented as follows. Firstly, purchase intentions of Korean regional products are determined by platform trust, seller trust, and product trust. Secondly, there is the effect of trust transfer among three types of consumer trust. That is, platform trust influences both seller trust and product trust and then seller trust influences product trust. Finally, institutional mechanism and familiarity are key determinants of platform trust and seller trust. The discussion and implications of the results are provided.

TCA: A Trusted Collaborative Anonymity Construction Scheme for Location Privacy Protection in VANETs

Zhang, Wenbo,Chen, Lin,Su, Hengtao,Wang, Yin,Feng, Jingyu Korean Society for Internet Information 2022 KSII Transactions on Internet and Information Syst Vol.16 No.10

As location-based services (LBS) are widely used in vehicular ad-hoc networks (VANETs), location privacy has become an utmost concern. Spatial cloaking is a popular location privacy protection approach, which uses a cloaking area containing k-1 collaborative vehicles (CVs) to replace the real location of the requested vehicle (RV). However, all CVs are assumed as honest in k-anonymity, and thus giving opportunities for dishonest CVs to submit false location information during the cloaking area construction. Attackers could exploit dishonest CVs' false location information to speculate the real location of RV. To suppress this threat, an edge-assisted Trusted Collaborative Anonymity construction scheme called TCA is proposed with trust mechanism. From the design idea of trusted observations within variable radius r, the trust value is not only utilized to select honest CVs to construct a cloaking area by restricting r's search range but also used to verify false location information from dishonest CVs. In order to obtain the variable radius r of searching CVs, a multiple linear regression model is established based on the privacy level and service quality of RV. By using the above approaches, the trust relationship among vehicles can be predicted, and the most suitable CVs can be selected according to RV's preference, so as to construct the trusted cloaking area. Moreover, to deal with the massive trust value calculation brought by large quantities of LBS requests, edge computing is employed during the trust evaluation. The performance analysis indicates that the malicious response of TCA is only 22% of the collaborative anonymity construction scheme without trust mechanism, and the location privacy leakage is about 32% of the traditional Enhanced Location Privacy Preserving (ELPP) scheme.

Why could we rely on the reviewer’s online review? : Review rating scheme, reviewer reputation scheme and navigation support

Un-Kon Lee,Kil-Soo Suh,Jai-Yeol Son 한국경영정보학회 2010 한국경영정보학회 학술대회논문집 Vol.2010 No.1

Online feedback mechanism, also known as reputation systems (Resnick et al. 2000), refers to the IT systems that enable the collection and dissemination of information about past transaction of traders (Dellarocas 2003, Resnick 2000, Pavlou & Dimoka 2006) As the word-of-mouth, they have referred to the online feedback to make their shopping decision, because they have trust in the online feedbacks and their reviewers. But in fact, some researchers have insisted that current online feedback mechanism was vulnerable to express the real value of shopping experience and this has resulted in distorting effect on customers’ purchase decision making (Dellarocas 2005, Resnick & Zeckhauser 2002, Duan & Whinston, 2005, Li & Hitt, 2008). For this remedy, current online feedback literature has mainly focused on the conceptual implication or structural assurance such as the seal of approval, and policy etc.. But, these are not enough to solve the above problem, because mechanism design modification and legal mechanism are usually more expensive to institute and people continue to seek to loophole (Bakos and Dellarocas 2002). In this research, we will propose another solution, the market driven mechanism consisted of review rating scheme, reviewer reputation scheme, and review navigation support by the peer customer community. By introducing the peer rating mechanism we could make feedback mechanism more cheap, sound and sustainable. Also, it could make them purchase decision via the more high qualified feedbacks, more credible reviewer and more effectively search and evaluate mechanism.

Research on 5G Core Network Trust Model Based on NF Interaction Behavior

Zhu, Ying,Liu, Caixia,Zhang, Yiming,You, Wei Korean Society for Internet Information 2022 KSII Transactions on Internet and Information Syst Vol.16 No.10

The 5G Core Network (5GC) is an essential part of the mobile communication network, but its security protection strategy based on the boundary construction is difficult to ensure the security inside the network. For example, the Network Function (NF) mutual authentication mechanism that relies on the transport layer security mechanism and OAuth2.0's Client Credentials cannot identify the hijacked NF. To address this problem, this paper proposes a trust model for 5GC based on NF interaction behavior to identify malicious NFs and improve the inherent security of 5GC. First, based on the interaction behavior and context awareness of NF, the trust between NFs is quantified through the frequency ratio of interaction behavior and the success rate of interaction behavior. Second, introduce trust transmit to make NF comprehensively refer to the trust evaluation results of other NFs. Last, classify the possible malicious behavior of NF and define the corresponding punishment mechanism. The experimental results show that the trust value of NFs converges to stable values, and the proposed trust model can effectively evaluate the trustworthiness of NFs and quickly and accurately identify different types of malicious NFs.

발달장애인서비스에서 보호자 신뢰형성과 신뢰행동 선택기제 연구

염태산(Yeom Tae san) 한국장애인복지학회 2018 한국장애인복지학 Vol.42 No.42

본 연구는 발달장애인 자녀를 둔 보호자가 발달장애인서비스에서 신뢰를 형성하는 과정과 맥락을 탐구하기 위한 연구이다. 이 연구에서는 Strauss와 Corbin의 근거이론방법을 활용하여 발달장애인을 자녀로 둔 어머니 19명을 대상으로 심층인터뷰를 실시하여 인터뷰 자료를 분석하였다. 연구 결과는 다음과 같다. 개방 코딩 과정에서 18개 범주와 65개의 코드가 발견되었다. 이를 통하여 도출된 축 코딩 패러다임은 ‘서비스 기대갖기(인과조건)’, ‘직원과 기관의 신뢰성 판단(맥락조건)’, ‘불균형한 신뢰 경험(현상)’, ‘권력불평등을 경험함(중재조건)’, ‘맡김과 떠남의 행동(작용과 상호작용)’, ‘서로 다른 이용자 역할 맡기(결과)’로 수렴되었다. 이야기 윤곽을 정리하는 과정에서 발견된 중심범주는 ‘불균형한 신뢰 경험, 권력관계 경험에 따라, 맡김과 떠남의 행동을 하며 직원 및 기관과 관계를 맺어가기’였다. 이어 진행된 과정 분석에서는, 보호자가 ‘기대와 불안의 서비스 진입단계 – 불균형한 신뢰성 평가와 경험 단계 – 맡김과 떠남의 대처와 이용자 역할 결정 단계’를 경험한다는 점이 정리되었다. 보호자의 신뢰형성은 특정한 신뢰/불신이 형성되는 사례를 중심으로 정리될 필요가 있다. 따라서 보호자가 경험한 다양한 서비스 상황을, 중심범주에 따라 신뢰성, 신뢰경험, 신뢰/불신행동 등으로 나누어 정리하였다. 정리된 73개의 사례를 중심으로 유형분석을 실시하여 9가지의 유효한 유형을 발견하였다. 본 연구자는 이러한 유형이 나타나는 상황을 검토하기 위하여 상황모형을 구성하였으며, 이러한 검토를 거쳐 ‘신뢰행동의 선택기제’를 설명하는 실체이론을 발견하였다. 제안 이론은, 발달장애인서비스를 이용하는 보호자가 직원 및 기관의 신뢰성과 지역사회의 서비스 대안조건을 고려하고, 직원/기관 동일시, 예상되는 사후가정사고 등의 인지적 과정을 통해 다양한 내용과 수준의 신뢰행동을 선택하는 기제를 설명한다. 상기 결과를 바탕으로, 본 연구자는 사회복지실천관계에서 사회복지사의 신뢰성뿐만 아니라 이용자의 관계 경험, 특히 ‘마지못해 순응하는 이용자’의 신뢰행동에 주목해야 할 이유에 주목한다. 사실 발달장애인서비스를 이용하는 보호자는 각기 다른 내용과 수준의 신뢰행동을 선택하지만, 이들의 취약성은 신뢰행동의 선택으로만 해결되지 않는다. 따라서 본 연구자는 서비스 대안 조건을 우호적으로 바꾸고, 신뢰를 협력으로 전환시키기 위한 실천 및 정책 대안을 제안한다. This study aims to explore the processes and contexts of parents’ trust-building in developmental disability services. For these aims, the grounded theory methodology was used to analyse the interviews from the 19 mothers of the people with developmental disabilities. The findings of this study are as follows. 18 subcategories, 65 codes were found during open coding process. Subsequently, axial coding results were ‘expecting services(causal condition)’, ‘judging trustworthiness of staffs/service agency(context condition)’, ‘experiencing unbalanced trust(phenomena)’, ‘experiencing the power inequality(intervening condition)’, ‘entrusting or refusing behaviors(actions and interactional strategies)’ and ‘determining various user roles(result).’ The core category of this study is “according to trustworthiness judging and the power inequality experiencing, mothers display entrusting and refusing behaviors and have relationships with service providers.” The trust-building processes in developmental disability services are ‘service entry with expectation and anxiety’ phase, ‘trust judging and experiencing’ phase, and ‘entrusting–or–refusing and user–role-determination’ phase. By the matrix of behavior strategies/entry opportunities and user roles, 9 valid types are discovered from 73 trust/distrust cases of mothers’ data. Based on the findings, ‘the trust-behavior selection mechanism theory’ is discovered. This substantial theory explains the various service users’ trust behaviors according to trustees’ trustworthiness judging, the alternative conditions calculation, the identification with trustees or services, and the anticipated counterfactual thoughts. The implication of this study are as follows. For the equality of social work relationship, user vulnerability and uncertainty should be more concerned. The choices on trust behaviors cannot solve the vulnerability problems of mothers. Therefore the practice and policy efforts were presented to make their choice alternatives more favorable.

Mitigating Blackhole and Grayhole Attack in MANET using Enhanced AODV with TLTB Mechanism

Nitin Khanna,Priyanka Sharma 보안공학연구지원센터 2016 International Journal of Future Generation Communi Vol.9 No.8

MANET is multi-hop network which is a decentralized and infrastructure-less network that includes collection of mobile nodes that are self configurable and co-operates with each other for transmission of data. It has dynamic nature in terms of topology. Due to this dynamic nature of topology and no fixed infrastructure in MANET, these nodes have to be dependent on each other for transmission of data and thus are prone to packet drop attacks like Blackhole, grayhole attack. These attacks hinder the smooth transmission of data between nodes and hampers effective communication. In this paper, a new mechanism Traffic Light Trust Based (TLTB) is proposed to detect both Blackhole attacks and Grayhole attacks. This mechanism works after modification in the standard AODV routing protocol and Watchdog mechanism. This mechanism uses color scheme to define trust level of a node or any path. Just like traffic light it includes three colors to depict the level of trust. AODV routing protocol packets are modified to include new fields for application of proposed trust mechanism. These Solutions are compared with Light-weight Trust Based (LTB) and EDRI mechanism for Normalized Control load, Packet Delivery Ratio, accuracy in Blackhole and Grayhole detection and reliability of paths.

Recently, with increasing interest in the subject of interfirm relationship mechanism, some information systems researchers point out that existing outsourcing theories are limited in explaining the choice of governance mechanisms in interfirm relational exchanges. Recognizing the importance of trust-commitment, this study focuses on the relationship of between control mechanism and commitment. Especially the role of trust as mediator is mainly researched. A mediation model was suggested on the basis of theoretical linkages from prior relevant studies. The research model was empirically tested with 73 IS outsourcing projects. The findings have significant impactions for further research and practice. Findings are as follows: First, outcome control, process control, social control had positive effects on trust and commitment. Second, inter-organizational trust played as a partial mediator on the relationship between control mechanisms and commitment. Based on these findings, the implication and the limitation of the study were presented including some directions for future studies.
