Multi-dimensional trust for context-aware services computing

作者:

Highlights:

• We introduce a novel trust model of IoT services considering dynamic environments.

• We define a subjective, objective, collusion resistant and bootstrapped trust model.

• We use the log score and error estimation to assess the model’s prediction accuracy.

• We use the ROC curves to measure the accuracy of the bootstrapping trust mechanism.

• We employ real dataset to show the performance and efficiency of the proposed model.
