The biometric authentication system of the future may include passwords sent through the human body. Researchers at the University of Washington have come up with a uniquely secure way to transmit data. They say it can be done using low-frequency transmissions generated by fingerprint sensors and touchpads found on devices we use everyday. Vikram Iyer, a PhD student in electrical engineering working in UW's Wireless and Mobile Systems Laboratory, spoke with Regarding ID's Gina Jordan about the paper he co-authored with two other UW researchers.
