Smartphone jiggles reveal your private data

摘要

The slight movements of your smartphone every time you tap on the touchscreen could be giving away what you are typing. Eavesdropping on a computer user's keyboard input is called keylogging. Often the culprit is software that runs invisibly, tracking what you type and reporting back to the attacker who installed it - making it easy to steal passwords or bank details. Keylogging is much harder to pull off on smartphones because most mobile operating systems allow only whatever app is on screen to access what you are typing, says security researcher Hao Chen of the University of California, Davis.
