The authors put together two tests. The first test was to determine whether people associated more with local images than foreign images. The test they developed had people classify pictures as trustworthy or untrustworthy based on the picture being foreign or local. The results, as predicted, were that people associate more with images of local places. The second test was to determine what qualities contribute to a website's perceived trustworthiness. It turns out that the quality of the site was the biggest factor. The authors say that they will use these tests to help develop tactics to create websites that users perceive as secure.
This paper brings up important points on security. People have to be able to trust websites and be able to identify fraudulent ones. This test to me though seems like a usability test. The authors were just gathering research to point in a direction for development practices than toward any real product. The next step that I would take would be to test these designs with phishing websites in a controlled lab to see how well people react when they are not just asked if they trust it, if the information they are entering has a factor as well.
