Hidden Markov Model using transaction patterns for ATM card fraud detection

Hidden Markov Model using transaction patterns for ATM card fraud detection

ATM card fraud is causing millions of naira in losses for the card payment business. The most accepted payment mode in today’s world is ATM card for online and regular purchasing; hence frauds related with it are also increasing. To find the fraudulent transaction, this study proposes a hidden Marko...
