Description

• Credit cards are used for purchasing goods and services by the help of virtual card for online transaction. • Tracing fraudulent transactions in this mode may not be possible because the attacker already steal the credit card. • Attackers need only little information for doing fraudulent transaction (secure code, card number, expiration date). • Risks of fraud transaction using credit card has also been increasing. • We proposed new credit card fraud detection system using Hidden Markov Model.
