Does Snapchat’s Lenses feature violate Illinois’ biometrics law?

"“In this particular case, it's not clear that Snapchat even used face recognition technology in a way that would implicate BIPA,” Yana Welinder, a lawyer and legal fellow with Stanford University, e-mailed. “It's possible that they are simply using face detection technology. If so, that would be similar to what many digital cameras do to identify a face in an image to focus the lens on the face.”"
