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
