Improving Agents Trust in Service-Oriented Environment Based on Entropy Structure and Information Ethics Principles

Recently, information ethics has been developed as a new perspective into ethics based on informational and computational considerations. As distrust is an essentially ethical problem in informational environments, it is plausible to think of solutions for trust-related problems in the field of information ethics. This article proposes an entropy-based trust model inspired by entropy structure and information ethics principles as a solution to trust problems in service-oriented environments. The system is capable of maintaining a robust awareness of the trustworthiness of agents. Whereas most trust models are developed as problem-specific solutions, the system proposed here is directly derived from a higher order ethical/informational philosophy that makes it better fit with many problems in an informational environment. The experimental results demonstrate that the performance of the proposed system is promising in terms of trust calculation accuracy and detection of deceptive behavior as well as the adaptation speed to environmental changes.
