The National Association of Attorneys General (NAAG) sent a letter to the Federal Trade Commission (FTC) on behalf of a bipartisan coalition of 43 state attorneys general to urge the federal government to update and strengthen the rules technology companies must follow under the federal Children’s Online Privacy Protection Act (COPPA).

Among other things, the attorneys general are urging the FTC to expand the definition of “personal information” to include biometric identifiers such as fingerprints, retina, and iris patterns, a DNA sequence, and data derived from voice data, gait data, and facial data, as well as avatars generated from a child’s image and likeness.
