With the growing importance of online markets and communities, users increasingly have to interact with unknown people. When choosing their interaction partners, they often lack direct experience and are forced to rely on ratings provided by others who are often unknown themselves. A number of reputation systems have been developed with the aim of improving the credibility of inferred reputatio...

The Grid approach provides the ability to access, utilize, and manage a variety of heterogeneous resources in virtual organizations across multiple domains and institutions. Selecting appropriate resources within such a distributed Grid environment to satisfy quality of service requirements is a complex and difficult task. This paper proposes a reputation management framework for Grids to facil...

We discuss and explore the concept of cross-community reputation between multiple communities. Sharing reputation between communities has several advantages in a world where users are members of several virtual communities and where reputation gained in one community may be a useful asset for other communities. The problems and policies regarding sharing reputation are discussed in this paper.

Increasingly widespread application of mobile agent, mobile agent system’s security is a prominent problem to be solved, mobile agent’s security question is critical. In this paper, based on cryptography, computer network security, mobile agent security architecture at the same time gives the practical methods and suggested ways can be used in other new security measures. The core problem is ho...

In mobile ad hoc networks (MANETs), tasks are conducted based on the cooperation of nodes in the networks. However, since the nodes are usually constrained by limited computation resources, selfish nodes may refuse to be cooperative. Reputation system is one of the main solutions to the node non-cooperation problem. A reputation system evaluates node behaviours by reputation values and uses a r...

Our reputation is important to us; we've experienced natural selection to care about our reputation. Recently, the neural processing of gains in reputation (positive social feedback concerning one's character) has been shown to occur in the human ventral striatum. It is still unclear, however, how individual differences in the processing of gains in reputation may lead to individual differences...
