CA Risk Authentication uses to gather the end-user device identification information.
The Device ID is a device identifier string that CA Risk Authentication generates and stores on the end users device to identify and track the device that the end user uses for logging into your online application and performing transactions. The Device ID information is in encrypted format.
Machine FingerPrint (also referred to as Device fingerprinting or PC fingerprinting in industry terms) represents the browser information and device identification attributes. These attributes include operating system, installed software applications, screen display settings, multimedia components, and other attributes. The attributes are gathered from the end users system and are analyzed to generate a device risk profile in Realtime. Some of the attributes that are collected from the end user device include:
For every transaction performed by the end user, CA Risk Authentication matches the corresponding MFP stored in its database with the incoming information. If this match percentage (%) is equal to or more than the value specified for the Device-MFP Match rule in Administration Console, then it is considered "safe".
DeviceDNA is a device identification and analytics technique that uses both Machine FingerPrint (MFP) and Device ID for more accurate information analyses. For accuracy, more information is collected than in case of MFP. For example:
