  Graphical passwords have been proposed as an alternative to alphanumeric
passwords with their advantages in usability and security. However, they still
tend to follow predictable patterns that are easier for attackers to exploit,
probably due to users' memory limitations. Various literatures show that
baroque music has positive effects on human learning and memorizing. To
alleviate users' memory burden, we investigate the novel idea of introducing
baroque music to graphical password schemes (specifically DAS, PassPoints and
Story) and conduct a laboratory study to see whether it is helpful. In a ten
minutes short-term recall, we found that participants in all conditions had
high recall success rates that were not statistically different from each
other. After one week, the music group coped PassPoints passwords significantly
better than the group without music. But there was no statistical difference
between two groups in recalling DAS passwords or Story passwords. Further more,
we found that the music group tended to set significantly more complicated
PassPoints passwords but less complicated DAS passwords.
