File Level Risk

The Heureka Risk Score is calculated using a weighted scoring system by assigning weights to each instance of risk by Risk Category and Characteristic. The total risk score for a file is calculated by multiplying the # of characteristic hits by a Risk Category Weight and a Characteristic Weight.

Example:

Heureka identified 5 AMEX cards in a single file

5 * 0.8 * 0.9 = File Risk Score of 3.6

The Weights break down as follows

• Bank Information Category = 0.4
  • Fractional Routing Number = 0.3
  • MICR Number = 0.3
• Credit Cards = 0.8
  • AMEX = 0.9
  • Diners = 0.9
  • Discover = 0.9
  • JCB = 0.9
  • Mastercard = 0.9
  • Visa 13 = 0.9
  • Visa 16 = 0.9
• Personal Information = 1.0
  • Social Security Number = .25
