2 STEP AUTHENTICATIONS ON ATM SYSTEM

multi-issue authentication (MFA) calls for users to offer a couple of proofs of their claimed identification before being granted access to a few set of assets. The idea behind MFA is that if one mechanism is compromised, it’s improbable that others will be as well, so there’s still a level of trust in the person’s authentication. Traditionally, MFA has required at least two of the following classes of authentication mechanisms: Ø a person’s expertise (what he or she is aware of) Ø a person’s possession (something the consumer has) Ø inherence (some bodily feature of the user) This taxonomy is becoming less beneficial as more overt login mechanisms are supplemented or replaced by passive contextual models, which we’re going to talk here.
