Reputation systems have become an increasingly important tool for highlighting quality information and filtering spam within online forums. However, the dependence of a user’s reputation on their history of activities seems to preclude any possibility of anonymity. We show that useful reputation information can, in fact, coexist with strong privacy guarantees. We introduce and formalize a novel...

Two studies investigated the mediating effects of liking and attributions of motives on the relationship between a ratee's reputation and helpful behaviors and raters' reward decisions. During managerial simulations, raters evaluated individuals after watching videotapes in which the individual's reputation and helpful behaviors were manipulated. Results indicated an interaction effect between ...

Traffic safety applications on vehicular ad hoc networks (VANETs) have drawn a lot of attention in recent years with their promising functions on car accident reduction, real-time traffic information support, and enhancement of comfortable driving experience on roadways. However, an inaccurate traffic warning message will impact drivers’ decisions, waste drivers’ time and fuel in their vehicles...

Firms need to continuously sense their business environment for being able to seize emerging opportunities and react against threats, such as loss of reputation. Corporate reputation is of particular importance as a valuable intangible asset. Thus, managing a firm’s corporate reputation as well as monitoring the reputation of its competitors may support sensing and seizing capabilities of a fir...

Parties of reputation systems rate each other and use ratings to compute reputation scores that drive their interactions. When deciding which reputation model to deploy in a network environment, it is important to find the most suitable model and to determine its right initial configuration. This calls for an engineering approach for describing, implementing and evaluating reputation systems wh...

A reputation protocol computes the reputation of an entity by aggregating the feedback provided by other entities in the system. Reputation makes entities accountable for their behavior. Honest feedback is clearly a pre-requisite for accurate reputation scores. However, it has been observed that entities often hesitate in providing honest feedback, mainly due to the fear of retaliation. We pres...

The current design of BGP implicitly assumes the existence of trust between ASes with respect to exchanging valid BGP updates. This assumption of complete trust is problematic given the frequent announcement of invalid — inaccurate or unnecessary — updates. This paper presents AS-CRED, a reputation service for ASes which quantifies the level of trust one can have with respect to its announcing ...

In this paper we provide experimental evidence for the importance of reputation in markets with experience goods. In this type of markets high quality cannot be enforced by complete and enforceable contracts. This leads to low efficiency or even the breakdown of markets. A potential remedy to overcome these inefficiencies is reputation formation. In order to study the causal effect of reputatio...
