I integrated touch id in my app.I want to use the touch id as a second secure authentication. I want to detect if new fingerprints were added or removed. Could you help me with programmatically usage?

There is no information available to an app that indicates when a fingerprint was added to or removed from the device.

Update

This is now possible in iOS9. The property evaluatedPolicyDomainState has been added to LAContext. - See https://stackoverflow.com/a/38399751/1066762

  • If the fingerprint database is modified (fingers were added or removed), the data returned any item in iOS 9 ? Can I detect if a new fingerprint was added to my device since the last time that I used? Because very easy to get the device passcode.I want to use the fingerprint as a way of secure authentication. – S.Ozkan Feb 25 '16 at 08:36
  • TouchID is no more secure than the passcode, since if you have the device passcode then you can enroll a new fingerprint. There is no information available that notifies you of changes to the TouchID data – Paulw11 Feb 25 '16 at 08:44

  • Yes, the APIs have been updated since I answered. I have added a link to that answer. Thanks – Paulw11 Nov 15 '16 at 10:22
