Senator Al Franken: Growing use of facial recognition technology raises serious privacy concerns. Franken: Biometric information, including facial features, is sensitive because it is unique and permanent. Franken calls on Facebook to turn off its tag suggestion feature by default, instead of having it on by default. There are currently no U.S. laws limiting government agencies or private companies from using facial recognition, witnesses said. Facebook: Only friends on Facebook can use the software to tag each other in photos, and Facebook users can prohibit tagging them in photos.”]
