我们表明，PC键盘，笔记本电脑键盘，电话和ATM垫容易受到攻击的基础上区分不同的键发出的声音。我们的攻击采用神经网络来识别被按下的键。我们还调查了为什么不同的键产生不同的声音，并提供了设计的谐音键盘，将抵抗这种类型的攻击提示。
We show that PC keyboards, notebook keyboards, telephone and ATM pads are vulnerable to attacks based on differentiating the sound emanated by different keys. Our attack employs a neural network to recognize the key being pressed. We also investigate why different keys produce different sounds and provide hints for the design of homophonic keyboards that would be resistant to this type of attack.
