使用安全的屏幕锁定机制对于防止未经授权的访问和危及存储在智能手机上的有价值数据非常重要。然而，许多用户仍然选择不使用任何这样的机制，并经常将不便列为主要原因。在本文中，我们认为，风险意识的缺乏在许多用户的不安全行为背后起着重要作用，而不是不便，这可以通过更有效地沟通风险来解决。为了验证这一假设，我们设计了一个信息视频，解释了未经授权访问没有屏幕锁定的智能手机的风险。我们将对照组（n = 114）与观看视频的治疗组（n = 114）在风险感知、关注和对安全屏幕锁定方法的态度方面进行了比较。随后，进行了一项后续研究，以了解视频是否有效地改变了参与者的行为（即，启用安全屏幕锁定）。我们发现治疗组和对照组参与者在感知严重性，风险意识，响应成本以及隐私和安全问题方面存在统计学显著差异。此外，随访研究显示，治疗组中启用安全屏幕锁定的参与者明显多于对照组（分别为48/96（50%）和21/98（21%））。最后，我们提出了我们的定性数据分析，以进一步解释参与者的行为。
Using a secure screen lock mechanism is important to prevent unauthorized access and compromise of valuable data stored on smartphones. However, many users still choose not to use any such mechanism and often state inconvenience as the main reason. In this paper, we argue that lack of risk awareness plays an important role behind many users’ insecure behavior rather than inconvenience, which can be addressed by communicating risks more effectively. To test this hypothesis, we designed an informational video explaining the risks of unauthorized access to smartphones with no screen lock. We compared a control group (n = 114) to a treatment group that viewed the video (n = 114) in terms of risk perceptions, concerns, and attitudes towards secure screen lock methods. Subsequently, a follow-up study was conducted to see whether the video was effective in changing participants’ behavior or not (i.e., enabling a secure screen lock). We found statistically significant differences between treatment and control group participants in terms of perceived severity, risk awareness, response cost, and privacy and security concerns. Furthermore, the follow-up study revealed that significantly more participants in the treatment group enabled a secure screen lock than those in the control group (48/96 (50%) vs. 21/98 (21%), respectively). Finally, we present our analysis of qualitative data to further explain participants’ behavior.
