A New Global Trust Model Based on Recommendation for Peer-To-Peer Network

The high degree of openness and autonomy of the P2P network gives rise to security warning of things such as fraud and cooperative cheating in the process of information exchange. The aim of this study is to develop a model to solve the problems which may arise in peers communications, and implement it in distributed environment. The model evaluates the reliability based on the evaluation nearness between presenters, and analyses the model on a practical basis. The model shows improvements compared to traditional models by greatly improving iteration speed and successful downloading rates.
