I've already posted this question on Stackoverflow, but got downvoted and told to post here instead. So here we go.
I am searching for citeable sources / papers that research about what is more secure in general: biometric authentication (something like touchID) in smartphones vs regular authentication (passwords, pincodes). I am looking for papers that actually come to a conclusion instead of answering the question with more questions. Surely this has to be measureable, since both are different types of authentication?
So far i googled on google scholar, but couldnt find any useful stuff. Any one else any idea?
