Facebook does not violate privacy by creating temporary “face signatures” of faces of persons (including non-users of Facebook) in pictures posted on Facebook. BIPA prohibits only use of “information” or “identifiers” that can be used to identify an individual. Facebook’s face signatures can’t be used to identify the persons in the pictures and those signatures are not stored on Facebook. Hence, they don’t violate BIPA. Plaintiff doesn’t have Art. III standing to complain about Facebook’s failure to provide him with its privacy policy as BIPA requires. As a non-user of Facebook, he was not affected by its privacy policy.
