User pattern oriented method and system for prevention of risk in card based transactions
View Patent ↗A method is provided to effectively preempt or prevent any instance of fraudulent, or otherwise unauthorized and/or undesired use of a Card by dynamic, user-configurable profiling of user and/or usage pattern information. The system implementation includes a duo of Payment applet and Fraud Rule detection Applet in separate packages provided on the Card and a Mobile Applet on smart phone of the Card owner, which trio interactively enabling the Card holder to keep and configure the CRM rules for effectively safeguarding against fraudulent and/or undesired transactions using the Card.
1 . A method for prevention of fraudulent transactions while using a card at any POS terminal, comprising:
a) provisioning, on a smart phone in charge of the owner of the card, a Mobile Applet programmed to record details of the transaction being entered, maintain previous transaction logs and manifest an interface menu for allowing the card owner to establish Card Risk Management data and responding to nullification alerts received for transactions determined as fraudulent;
b) provisioning the card with—
a Fraud Rule detection Applet programmed for authenticating details of the transaction being entered with previous transaction logs and Card Risk Management data set by Card holder/owner; and
a Payment applet programmed to log and share details of the transaction being entered with the Fraud Rule detection applet;
c) at any instance of initiation of a payment transaction using the card at any POS terminal, invoking the Mobile Applet on the smart phone to relay the details of the transaction being entered to the Fraud Rule detection Applet on the card; and
d) upon receiving, the details of the transaction being entered from the Mobile Applet, executing the Fraud Rule detection Applet on the card to arrive at a decision between allowing and disallowing the transaction being entered by comparing the details of the transaction being entered with the previous transaction logs and the Card Risk Management data, to thereby abort fraudulent transactions while using the card at any POS terminal.
2 . The method for prevention of fraudulent transactions while using a card at any POS terminal according to claim 1 ,
wherein provisioning the card with a Payment applet and a Fraud Rule detection Applet in discrete packages is undertaken as a stage in a process selected between the issuance and production of the card.
3 . The method for prevention of fraudulent transactions while using a card at any POS terminal according to claim 1 ,
wherein provisioning the card with a Payment applet and a Fraud Rule detection Applet in discrete packages is undertaken as an OTA update to the NVM of said card.
4 . The method for prevention of fraudulent transactions while using a card at any POS terminal according to claim 1 , wherein framing at instance of the card owner, the terms for allowance of transactions using the card is undertaken by means of the Mobile Applet whereby the card owner is at choice of defining a set of parameters including GeoLocation, Transaction Time, Amount, City Code which are and alternatively likely to be incidental to usual usage of the card by the card owner.
5 . The method for prevention of fraudulent transactions while using a card at any POS terminal according to claim 1 ,
wherein decisioning includes either between:
a) allowing the transaction being entered if the parameters of the Card Risk Management data, previous transaction logs and details of the transaction being entered match; and
b) disallowing the transaction being entered if the parameters of the Card Risk Management data, previous transaction logs and details of the transaction being entered do not match.
6 . The method for prevention of fraudulent transactions while using a card at any POS terminal according to claim 5 ,
wherein decisioning further includes issuance of an nullification alert via SMS to the card owner for inviting his response to be entered via the Mobile Applet, the response being chosen between:
a) inaction, to therefore avoid the transaction being entered;
b) confirmation by reply SMS, to therefore avoid the transaction being entered; and
c) overriding the nullification by reply SMS, to therefore allow the transaction being entered.
7 . A system for prevention of fraudulent transactions while using a card at a POS terminal, comprising:
a) a Mobile Applet for installation on a smart phone of the card owner, said Mobile Applet being programmed to record details of the transaction being entered, maintain previous transaction logs and manifest an interface menu for allowing the card owner to establish Card Risk Management data and responding to nullification alerts received for transactions determined as fraudulent;
b) a card provisioned with a discrete pair of applets being a Fraud Rule detection Applet programmed for authenticating details of the transaction being entered with previous transaction logs and Card Risk Management data set by Card holder/owner and a Payment applet programmed to log and share details of the transaction being entered with the Fraud Rule detection applet.
8 . The system for prevention of fraudulent transactions while using a card at a POS terminal according to claim 7 , wherein the card is selected between payment and non-payment cards.
9 . The method for prevention of fraudulent transactions while using a card at any POS terminal according to claim 1 , further comprising, when disallowing the transaction being entered, generating a reaction code inserted into a standard EMV response to the POS terminal that causes the terminal to abort the transaction locally.
