OPTET D2.4 Socio-economic evaluation of trust and trustworthiness
In this deliverable, we present the work done on Trust and Trustworthiness models after the D2.3 milestone. The work focused on extending the models, enhancing their performance as well as accuracy when used across the socio-technical system lifecycle. This deliverable also presents the details of the validation and evaluation of these models, and their integration into the WP8 use cases (DADV, AAL and SWC).

The Trustworthiness model was enhanced with new asset types, threats and controls restructured in a modular way to allow easier future extension and performance optimisation as systems complexity grows. The GE presented in the 2nd year review was made more robust and finally used for the evaluation requested by the reviewers to show how both the model as well as the GE support the system design and provide additional value compared to the traditional modelling process.

The evaluation on the Trust model was done by conducting a large-scale experiment on users of a fictional search engine and questioning them about their perception of trust into the system depending on various factors. Furthermore, we analysed the effect of user trust on the legal framework.

The evaluation results and identified software bugs have already been taken into consideration in the final release of the OPTET GE’s.

Abstract

In this deliverable, we present the work done on Trust and Trustworthiness models after the D2.3 milestone. The work focused on extending the models, enhancing their performance as well as accuracy when used across the socio-technical system lifecycle. This deliverable also presents the details of the validation and evaluation of these models, and their integration into the WP8 use cases (DADV, AAL and SWC).

The Trustworthiness model was enhanced with new asset types, threats and controls restructured in a modular way to allow easier future extension and performance optimisation as systems complexity grows. The GE presented in the 2nd year review was made more robust and finally used for the evaluation requested by the reviewers to show how both the model as well as the GE support the system design and provide additional value compared to the traditional modelling process.

The evaluation on the Trust model was done by conducting a large-scale experiment on users of a fictional search engine and questioning them about their perception of trust into the system depending on various factors. Furthermore, we analysed the effect of user trust on the legal framework.

The evaluation results and identified software bugs have already been taken into consideration in the final release of the OPTET GE’s.
