### Risk Perceptions
#### 5.2.3 Perceptions on Information Exploitation in ID theft  
The participants in the questionnaire were asked how they rate to what degree they thought that different information could be used to perform identity theft with the alternatives: _1--Very small degree_, _2--Small degree_, _3--Large degree_ and _4--Very large degree_. The results can be seen in Table 19 where we have used the average to rank the information assets according to each other. The one piece of information that would people thought would let an attacker perform an ID theft was account and password details with 80.9% of people rating it as to a _very large degree_. In second place, we have debit/credit card numbers with 77.4% on very large degree. When we asked this question, we were just considering the front-facing numbers, but people might have thought I meant all the numbers on the card. We can see that over around 66% of people perceive social security numbers as a very large degree in regards to the information risk value, even though the social security number is not classified as sensitive data in Norway, and should, in theory, not let attackers abuse your identity by itself. How people rated the rest of the information points asked can be seen in Table 19.
