FRAUD MONITORING SYSTEM
A payment processing system includes a server that processes a request for a transaction between a customer and a merchant. The customer is associated with a customer profile defining a customer security level that is one of a plurality of customer security levels. The merchant is associated with a merchant profile defining a merchant security level that is one of a plurality of merchant security levels. A risk service determines a risk for the request based on transaction data of the purchase transaction request, the customer profile, and the merchant profile. The risk service determines the risk by operating at a risk assessment level that is one of a plurality of risk assessment levels at which the risk service operates depending on the customer and the merchant security level defined by the customer and the merchant profile. The risk service generates a fraud warning based on a result.
1 . A system comprising:
a server that processes a purchase transaction request for a transaction between a customer and a merchant, the customer being associated with a customer profile defining a customer security level that is one of a plurality of customer security levels, and the merchant being associated with a merchant profile defining a merchant security level that is one of a plurality of merchant security levels; and
a risk service that determines a risk for the purchase transaction request based on transaction data of the purchase transaction request, the customer profile, and the merchant profile;
wherein the risk service determines the risk by operating at a risk assessment level that is one of a plurality of risk assessment levels at which the risk service operates depending on the customer security level and the merchant security level defined by the customer profile and the merchant profile, respectively; and
wherein the risk service generates a fraud warning based on a result of the determination.
2 . The system of claim 1 , wherein:
the plurality of customer security levels includes a first customer security level at which the customer profile contains a first set of customer data, a second customer security level at which the customer profile contains a second set of customer data that includes more information than the first set of customer data, and a third customer security level at which the customer profile contains a third set of customer data that includes more information than the second set of customer data;
the plurality of merchant security levels includes a first merchant security level at which the merchant profile contains a first set of merchant data, a second merchant security level at which the merchant profile contains a second set of merchant data that includes more information than the first set of merchant data, and a third merchant security level at which the merchant profile contains a third set of merchant data that includes more information than the second set of merchant data.
3 . The system of claim 1 , further comprising:
a central database located remotely from the server and configured to store information, the information including the customer profile, the merchant profile and transaction data; and
a distributed cache that is connected to the central database configured to store and synchronize a set of the information, rather than at the central database;
wherein the risk service determines the risk of the purchase transaction request based on the set of the information without accessing the central database.
4 . A method comprising:
processing, by a server, a purchase transaction request for a transaction between a customer and a merchant, the customer being associated with a customer profile defining a customer security level that is one of a plurality of customer security levels, and the merchant being associated with a merchant profile defining a merchant security level that is one of a plurality of merchant security levels;
determining, by a risk service, a risk for the purchase transaction request based on transaction data of the purchase transaction request, the customer profile, and the merchant profile; and
generating, by the risk service, a fraud warning based on a result of the determination;
wherein the risk service determines the risk by operating at a risk assessment level that is one of a plurality of risk assessment levels at which the risk service operates depending on the customer security level and the merchant security level defined by the customer profile and the merchant profile, respectively.
5 . The method of claim 4 , wherein:
the plurality of customer security levels includes a first customer security level at which the customer profile contains a first set of customer data, a second customer security level at which the customer profile contains a second set of customer data that includes more information than the first set of customer data, and a third customer security level at which the customer profile contains a third set of customer data that includes more information than the second set of customer data; and
the plurality of merchant security levels includes a first merchant security level at which the merchant profile contains a first set of merchant data, a second merchant security level at which the merchant profile contains a second set of merchant data that includes more information than the first set of merchant data, and a third merchant security level at which the merchant profile contains a third set of merchant data that includes more information than the second set of merchant data.
6 . The method of claim 4 , further comprising:
storing, by a central database, information, the information including the customer profile, the merchant profile and transaction data;
storing, by a distributed cache rather than in the central database, a set of the information;
determining, by the risk service, the risk of the purchase transaction request based on the set of the information without accessing the central database.
