چکیده

Trust is part of our daily life and thus can be used as a mechanism for providing security in computer networks. In this paper, by considering the dynamic nature of trust, especially the temporal and spatial characteristics in security of society, we describe trust from four factors: access time, place, history behavior and risk control strategy and then apply fuzzy clustering method and information entropy theory to design a weight allocation algorithm for these factors to compute a value for trust.

A Novel Trust Computation Method Based on User Ratings to Improve the Recommendation

Today, the trust has turned into one of the most beneficial solutions to improve recommender systems, especially in the collaborative filtering method. However, trust statements suffer from a number of shortcomings, including the trust statements sparsity, users' inability to express explicit trust for other users in most of the existing applications, etc. Thus to overcome these problems, this ...

An Access Control Method based on Scenario Trust

Access control is an important element in network security. Meanwhile, trust provides a new direction for access control in open network environments. Based on the dynamic nature of trust, we study the temporal and spatial characteristics in the security of society and propose the concept of scenario trust in which we consider four factors: access time, place, history behavior and risk control ...

FRTRUST: a fuzzy reputation based model for trust management in semantic P2P grids

Grid and peer-to-peer (P2P) networks are two ideal technologies for file sharing. A P2P grid is a special case of grid networks in which P2P communications are used for communication between nodes and trust management. Use of this technology allows creation of a network with greater distribution and scalability. Semantic grids have appeared as an expansion of grid networks in which rich resourc...

Infrared Image Segmentation using Adaptive FCM Algorithm Based on Potential Function

Traditional Fuzzy C-means segmentation algorithm requires to set clustering number in advance, and to calculate image clustering center by the iterative arithmetic. So the traditional algorithm is sensitive to the initial value and the computation complexity is high. In order to improve the traditional Fuzzy Cmeans algorithm, this paper presents an infrared image segmentation method using adapt...
