Hackers can detect what is being typed with a smartphone: Researchers

New York: Using just a smartphone, hackers can listen to what is being typed with remarkable accuracy and access your personal information.
According to researchers from Dallas-based Southern Methodist University (SMU), it’s possible to access your information in a subtler way: by using a nearby smartphone to intercept the sound of your typing.
The team from from SMU’s Darwin Deason Institute for Cybersecurity found that acoustic signals, or sound waves, produced when we type on a computer keyboard can successfully be picked up by a smartphone.
The sounds intercepted by the phone can then be processed, allowing a skilled hacker to decipher which keys were struck and what they were typing.
