Application of Filters - Filtering Rules

FraudSight’s optional fraud filter rules allow you to exercise a finer control over the application of the filters based upon a number of different criteria such as product or service name, method of order entry, and several more.

The FraudSight filtering system provides you the flexibility of restricting which transactions you submit to the filtering service and which filters the system applies to which groups. You accomplish this by defining Filtering Rules with your Relationship Manager and/or Implementation Manager.

The system provides you the flexibility of restricting which transactions are submitted to the filtering service and which filters the system applies to which groups. This is accomplished by defining Filtering Rules.

For each Filtering Rule you first define a subgroup of transactions by selecting one of the following Flow Selectors: Report Group, Billing Descriptor, orderSource, or MID (for Payment Facilitators, flow control by MID or order source only). Only one selector can be applied per rule. After selecting a particular Flow Selector, you then select which filters to have applied to that subset of transactions. You can define the Filter Rules so that filters are ORed (transaction filtered when any one of the filters conditions met), or ANDed (transaction filtered when multiple filter conditions met). Table 1-9 defines five rules that a merchant might define.

TABLE 1-9 Example - Fraud Filtering Service Rules

Filter	Flow Selector	Filters
1	Report Group = "XYZ"	Prepaid
2	Report Group = "XYZ"	International
3	orderSource = "recurring"	Prepaid + Prior Chargeback
4	orderSource = "ecommerce"	Card Velocity + Security Code No-match
5	Billing Descriptor = "GoldMember"	Prepaid + International

Table 1-9 defines five Filter Rules that a merchant might use. These rules would be applied as follows:

• Filters 1 and 2 apply to the subset of transactions that are members of Report Group XYZ and use the Prepaid and International Filters. Since the Filter Rules are defined separately, the rules are ORed. So, if a transaction uses either a Prepaid card or a card of International origin, the filtering occurs.

• Filter 3 applies to the subset of transactions that have an orderSource value set to recurring. Filtering occurs only if both the criteria for the Prepaid Filter AND the Prior Chargeback Filter are met.

• Filter 4 applies to the subset of transactions that have an orderSource value set to ecommerce. Filtering occurs only if both the criteria for the Card Velocity Filter AND the Security Code No-Match Filter are met.

• Filter 5 applies to the subset of transactions that have an Billing Descriptor value set to GoldMember. Filtering occurs only if both the criteria for the Prepaid Filter AND the International Filter are met.
