Using the fuzzy vault to correct inaccuracies in authentication data

In a number of authentication methods, there are inaccuracies due to the impossibility or complexity of reproducing the authentication data exactly coinciding with the data specified by the user during initial registration in the information system. Such methods include, in particular, biometric methods as well as some methods based on graphic passwords. The paper explores the possibility of using the fuzzy vault scheme to correct such inaccuracies and provide high resistance to the selection of authentication data in a keyboard authentication system and in a graphical password authentication system.
