巴洛克音乐对PassPoints图形密码的影响
The effect of baroque music on the PassPoints graphical password
摘要：
图形密码已被证明是传统字母数字密码的可能替代品。然而，他们仍然倾向于遵循更容易攻击的可预测模式。问题的关键在于用户的记忆力有限。用户是密码认证机制中最薄弱的环节。这表明巴洛克音乐对人类的记忆和学习有积极的影响。我们引入巴洛克音乐的PassPoints图形密码方案，并进行了实验室研究。结果表明，在短时记忆实验中，听音乐组和不听音乐的对照组之间没有统计学差异，都有较高的回忆成功率。但在长期回忆中，音乐组的表现明显更好。我们还发现，音乐组倾向于设置更复杂的密码，这些密码通常更能抵抗字典和其他猜测攻击。但与对照组相比，音乐组在短期和长期测试中都花费了更多的时间登录。此外，似乎背景音乐在热点方面不起作用。
英文摘要：
Graphical passwords have been demonstrated to be the possible alternatives to traditional alphanumeric passwords. However, they still tend to follow predictable patterns that are easier to attack. The crux of the problem is users' memory limitations. Users are the weakest link in password authentication mechanism. It shows that baroque music has positive effects on human memorizing and learning. We introduce baroque music to the PassPoints graphical password scheme and conduct a laboratory study in this paper. Results shown that there is no statistic difference between the music group and the control group without music in short-term recall experiments, both had high recall success rates. But in long-term recall, the music group performed significantly better. We also found that the music group tended to set significantly more complicated passwords, which are usually more resistant to dictionary and other guess attacks. But compared with the control group, the music group took more time to log in both in short-term and long-term tests. Besides, it appears that background music does not work in terms of hotspots.
