Risk Score Calculation

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 automatically identifies 5 MasterCard cards in a single file with no additional risk characteristics. The calculation is as follows:

Characteristic Hits (5) x Category Weight (.8) x Characteristic Weight (.9) = File Risk Score

5 x 0.8 x 0.9 = File Risk Score of 3.6

The Category Weights are shown below

• 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
• Words Category = 0.01
  • Offensive = 1.0
