The current state of rules for use of facial recognition technology is literally all over the map. Next month, the city council in Portland, Oregon will hold a public meeting about blocking use of the technology by private companies, as well as by the government. San Francisco, Oakland, Calfornia, and Somerville, Massachusetts, already have banned the use of facial recognition technology by city agencies; Seattle’s police stopped using it last year; and Detroit has said facial recognition can be used only in connection with investigation of violent crimes and home invasions (and not in real time).

State governments have their own rules too. In October, California joined New Hampshire and Oregon in prohibiting law enforcement from using facial recognition and other biometric tracking technology in body cameras. Illinois passed a law that permits individuals to sue over the collection and use of a range of biometric data, including fingerprints and retinal scans as well as facial recognition technology. Washington and Texas have laws similar to the one in Illinois, but don't allow for private suits.
