I am certainly not excited about private interests possessing data linking bio-metrics to individuals (I'm sure companies such as Facebook already possess this data). Currently users control whether or not identification occurs (tickets/ids shown, login credentials provided), with bio-metrics organizations have full autonomy to identify individuals. That dynamic shift seems very dangerous to me.
