Two new rules called Device User Velocity and Device User Maturity have been introduced in this release.
Device User Velocity
The new Device User Velocity rule allows a device to be used by n distinct users in any configured duration. If the device is used by more than n distinct users in the configured duration, then it indicates fraudulent activity.
For example, consider a configuration of 5 transactions per device in 60 minutes. This rule is not triggered when User1 performs five transactions per hour from Device1. But if there are transactions from five different users using Device1 in one hour, then this rule is triggered.
Device User Maturity
The Device User Maturity rule enables setting a level of trust in the device. For example, a User-Device association that has existed for a month, assuming that there has been no fraudulent activity identified for that user or device, should be more trusted than a User-Device association that has been established recently.
