Using NFC, IBM brings dual-factor authentication to mobile
ZURICH, Switzerland — Banks and major Web sites often combine passwords with people’s phones to offer more secure two-factor authentication when logging onto a service with a PC. But what happens when you’re logging on using a phone?
NFC wireless links can be used to let people exchange contact information by bumping phones together or to pay for products by waving a phone close to a payment terminal, but it also can be used to enable dual-factor authentication in the mobile device era, said said Diego Ortiz-Yepes, a security and encryption researcher at IBM Research in Zurich.
