The authors explore the use of extrinsic motivation to improve the state of user-centered security mechanisms. Specifically, they study applications of visual scores as user incentives in the context of secure device pairing. They develop a scoring functionality that can be integrated with traditional pairing approaches which involve the manual comparison of numbers. They then report on a usability study that they performed to evaluate the effect of scoring on the performance of users in comparison operations. Their results demonstrate that individuals are likely to commit fewer errors and show more acceptances when working with the scoring based pairing approach.
