Trustworthiness Model Representation

of all the sensors involved and the
observations made by the system can be
trusted.
We propose a model that allows for
inclusion of the relevant contributing
factors, while enabling the user to selectively
emphasize important factors and deprecate
those of less importance. This model can
then be used to represent the overall
solution trustworthiness as a cumulative
single score. The proposed model does not
mandate using just the single cumulative
score: Users can still visualize individual
Trust Scores using a ‘radar’ or ‘spider’
diagram. We will demonstrate such a model
in the following section.
Trust in the food industry may involve
monitoring a different set of parameters. It
may require trusting the production,
shipping and storage process. For example, a
consumer can trust a food product provided
the source of the ingredients, the production
process, the packaging, transportation and
storage can be trusted and verified. Thus,
each application may require a different set
of parameters to establish trust.
Trustworthiness of a solution requires
measuring the Trust Score of each
component or entity involved in delivering
that solution. The overall trustworthiness of
a solution can then be a weighted
combination of the Trust Score of each
element of the solution.

As noted earlier, trust may mean different
things in different applications. Trust in a
home security system may require all
components involved in monitoring the
perimeter of a house to be trustworthy.
Home security system trust would involve
ensuring all security system hardware and
software components are trustworthy.
Additionally, the solution requires that the
security system configuration, the location
Components of Trustworthiness
Trust provides a measure of confidence. As
discussed above, each application may
involve a different set of parameters or
