"If I look at an image of a palm, I probably can't tell it's you versus me necessarily. But that doesn't say it's not identifiable, because if it wasn't identifiable they wouldn't be using it," Stanford Institute for Human-Centered Artificial Intelligence Privacy and Data Policy Fellow Jen King said.
