论文摘要
IFTT-PIN是Roth等人介绍的PIN-访问方法的自校准版本。 （2004）[1]。在[1]中，数字分别分为两组并分配了颜色。为了传达其数字，用户按按钮，其颜色与分配给数字相同的颜色，因此可以在几次迭代后通过outhination识别。 IFTT-PIN使用相同的原理，但不会为每个按钮预分配颜色。相反，用户可以自由选择用于每种颜色的按钮。纽扣彩色映射仅存在于用户的脑海中，并且永远不会直接传达到接口。换句话说，IFTT-PIN同时添加用户的PIN及其首选的纽扣到颜色映射，这是一个称为自校准的过程。在本文中，我们介绍了具有和不进行自我校准的IFTT-PIN的在线互动演示，并介绍了关键概念和假设，从而使自我校准成为可能。可以通过https://youtu.be/5i1ibpjdlhm在https://jgrizou.io/iftt-pin/上对IFTT-PIN进行测试。我们审查了脑部计算机界面领域的相关工作，并进一步提出了自我校准，作为一种保护用户免受肩膀冲浪攻击的新方法。最后，我们引入了一项金库破解挑战，以作为对我们研究所进行非正式测试的可用性和安全性测试。使用IFTT-PIN，我们希望演示一种新的交互式体验，用户可以在其中积极决定并在现场使用界面。自我校准范式可能会导致在其他应用或领域中进行相互作用的新机会。我们希望这项工作能激发社区发明它们。
IFTT-PIN is a self-calibrating version of the PIN-entry method introduced in Roth et al. (2004) [1]. In [1], digits are split into two sets and assigned a color respectively. To communicate their digit, users press the button with the same color that is assigned to their digit, which can thus be identified by elimination after a few iterations. IFTT-PIN uses the same principle but does not pre-assign colors to each button. Instead, users are free to choose which button to use for each color. The button-to-color mapping only exists in the user's mind and is never directly communicated to the interface. In other words, IFTT-PIN infers both the user's PIN and their preferred button-to-color mapping at the same time, a process called self-calibration. In this paper, we present online interactive demonstrations of IFTT-PIN with and without self-calibration and introduce the key concepts and assumptions making self-calibration possible. IFTT-PIN can be tested at https://jgrizou.github.io/IFTT-PIN/ with a video introduction available at https://youtu.be/5I1ibPJdLHM. We review related work in the field of brain-computer interface and further propose self-calibration as a novel approach to protect users against shoulder surfing attacks. Finally, we introduce a vault cracking challenge as a test of usability and security that was informally tested at our institute. With IFTT-PIN, we wish to demonstrate a new interactive experience where users can decide actively and on-the-fly how to use an interface. The self-calibration paradigm might lead to novel opportunities for interaction in other applications or domains. We hope this work will inspire the community to invent them.
