Poster abstract: Context-free wearable side-channel leaks your typing privacy
Yang Liu, Zhenjiang Li · 2018
In this poster, we present out recent work, aLeak, which revisits a crucial privacy problem that can the sensitive information, e.g., passwords, frequently typed by user on mobile devices be inferred through the motion sensors of wearable device on user's wrist? Prior works have achieved initial success under certain context-constrained conditions: 1) the horizontal keypad plane, 2) the known keyboard size, 3) and/or the last keystroke on a fixed “enter” button. In this work, we take one step further to fully demonstrate and more importantly alarm people the further risks of typing privacy leakage in much more generalized context-free scenarios through addressing a seriesseries of unsolved challenges.
