Abstract
We explore the use of extrinsic motivation to improve the state of user-centered security mechanisms. Specifically, we study applications of scores as user incentives in the context of secure device pairing. We develop a scoring functionality that can be integrated with traditional pairing approaches. We then report on a usability study that we performed to evaluate the effect of scoring on the performance of users in comparison operations. Our results demonstrate that individuals are likely to commit fewer errors and show more acceptance when working with the scoring based pairing approach. Framing pairing as a game and providing feedback to users in the form of a score is an efficient way to improve pairing security, particularly among users such as children who may not be aware of the consequences of their decisions while performing security tasks.
