用户对验证码的感知：大学用户与互联网用户的比较研究
User Perception of CAPTCHAs: A Comparative Study between University and Internet Users
AI总结：
本研究通过调查250多名大学与互联网用户，发现验证码难度增加导致用户挫败并担忧安全可靠性，为设计更安全友好的验证码提供见解。
摘要：
验证码通常用于在网络上区分人类用户和机器人用户。然而，尽管存在多种类型的验证码，其安全性和可用性仍令人担忧。为解决这些问题，我们对来自大学校园和亚马逊土耳其机器人（Amazon Mechanical Turk）的超过250名参与者进行了调查。我们的目标是收集用户对当前验证码实现的安全性和可用性的看法。通过使用统计和主题方法分析数据后，我们发现，由于难度不断增加，用户在应对当前验证码挑战时感到困难。因此，他们体验到挫败感，这对用户体验产生了负面影响。此外，参与者对这些系统的可靠性和安全性表达了担忧。我们的发现可以为创建更安全且更友好的验证码技术提供有价值的见解。
英文摘要：
CAPTCHAs are commonly used to distinguish between human and bot users on the web. However, despite having various types of CAPTCHAs, there are still concerns about their security and usability. To address these concerns, we surveyed over 250 participants from a university campus and Amazon Mechanical Turk. Our goal was to gather user perceptions regarding the security and usability of current CAPTCHA implementations. After analyzing the data using statistical and thematic methods, we found that users struggle to navigate current CAPTCHA challenges due to increasing difficulty levels. As a result, they experience frustration, which negatively impacts their user experience. Additionally, participants expressed concerns about the reliability and security of these systems. Our findings can offer valuable insights for creating more secure and user-friendly CAPTCHA technologies.
