Researchers defeat voice biometric security by targeting common liveness approaches

Shortcomings in voice presentation attack detection are making it surprisingly easy to defeat biometric defenses.

A pair of Canadian computer scientists trying to get around voice authentication found it easy to do so – claiming a success rate of up to 99 percent in only six attempts against the least effective biometric security system tested. The University of Waterloo researchers have published their findings in the IEEE Computer Society's digital library.

"Our attack," their report states, "targets common points of …
