You may never have to remember your mother's maiden name, your first pet, or the name of your first concert again.

Israeli tech company NICE Systems has launched a voice authentication system for call centers that is already in use at a few banks, said Tamar Sharir, director of fraud and authentication services at the company.

The software is able to identify a person calling the bank within 15 seconds, just by their voice, with more than 90 percent accuracy, Sharir said.

A customer service representative wouldn't even necessarily have to ask your name, as the bank would be able to identify you after just a few seconds, she said.

She declined to identify any companies now using the technology, but said that "several global financial services" were currently using it, as well as a few telecommunications companies.

In addition to helping prevent fraud, the technology is designed to improve customer experience, and make call centers more efficient, she said.
