摘要：Shoulder surfing or adversarial eavesdropping to infer users’ keystrokes on physical QWERTYkeyboards continues to be a serious privacy threat. Despite this, practical and efficient countermeasures against suchattacks are still lacking. In this paper, we propose keyboard randomization as a simple, yet effective, countermeasureagainst various types of keystroke inference attacks. Our proposal consists of several keyboard randomization strategieswhich randomizes or changes the position of keys on the keyboard. The randomized keyboard is then projected to thetyping user by means of an augmented reality wearable device. As the randomized keyboard is visually superimposedover the actual physical keyboard, and is visible only to the typing user through the augmented reality device, it acts asan effective countermeasure against both side-channel and visual-channel based keystroke inference attacks. Weimplement our proposed solution on a commercially available augmented reality device and conduct preliminaryevaluations to validate its performance and effectiveness.
