    What have you tried so far? What research have you done regarding fingerprint-based logins? What attack vectors have your read about?

    As a fresher you still have access to a lot of resources. Just googling "fingerprint login test" returns a lot of answers. Similarly, Google Scholar: scholar.google.com/…

Here are a couple of positive & negative test cases for the fingerprint scanner. You can validate feature(login in your case)based on what is allowed per spec.

  • Register any of your fingers(say thumb of your right hand).
  • Swipe with a registered finger on log-in from a locked screen.
  • Swipe with a registered finger on log-in after the restart.
  • Swipe registered hand in an up-to-down, down-to-up, right-to-left, left-to-right, circular motion, wave it above without contact, with gloves on, with oily fingers etc.
  • Try with the left thumb(counterpart of registered) with the above scenarios.
  • Try with all other fingers of the hand.
  • Try with the palm of the hand.
  • Try with partial contact of the registered finger - left portion up, right portion up, top portion up, bottom portion up
  • Try with the back of the registered finger.
  • Try with registered composite keys(ex. more than one finger) this will spawn its own set of scenarios.
  • Try swiping with registered or with unregistered fingers when a user is logged in(not locked)
  • Try after screensaver locks the screen.
  • Try after installing updates for fingerprint reader software or other software.
  • Try with hardware updates.
  • Try with a mould created from your registered finger.(I used favicol to create mask)
  • Slow speed swipe, medium speed swipe, high-speed swipe.
  • Try repeated locking and swiping to see if it stops working after a certain point.
  • Check-in combination with other authentication options such as card reader.
  • Try when the computer is in sleep mode.
  • Try after hitting ctrl + alt + del or without hitting those keys.
  • Try with the power cord on or on battery mode.

    Why has someone downvoted this answer without providing any feedback? That's very unconstructive behaviour.

Apart from the above mentioned test cases, below are the few other test cases which are executed by software testing company to test the fingerprint systems:-

  • Test the performance of fingerprint system for allowing the valid user i.e Time taken by the system to allowed the access of valid user.
  • Test the performance of system for rejecting the invalid user ie. Time taken by the system to reject the invalid user.
  • Sometimes valid user is not allowed to access the fingerprint system. For this case, test what other way provided to user in order to access the system.
  • Test the system with valid user finger in different ways say:-
    • Test the system with valid user when finger is dipped with water.
    • Test the system with valid user when finger is dipped with any color or sketch mark on finger.
    • Test the system with valid user when finger is covered with transparent gloves
