Global score computation
The scores from the different partner technologies are not the same, so each one is converted into a score in the range 0-100 where 100 is the lowest risk. The following table summarises the score for each partner technology.
| Partner technology score | Original scoring | Transformation |
|---|---|---|
| ThreatMetrix | -100 to 100 (lowest risk) | Scores outside this range are given the values -100 or +100 as appropriate. Then scores transformed to 0-100 range (so -100 becomes 0, 0 becomes +50 and 100 remains as 100) |
Once the score from each partner technology is capped so that it falls within the original score range, it is transformed using the formula below. The priority for each technology that was configured in the FP Portal is taken into account by the formula.
In the formula below * P: Partner * G: Global * PR: Priority
P.x is the original partner score before transformation
P.min is minimum possible value in the partner score range
P.max is maximum possible value in the partner score range
G.min is minimum possible value in the global score range (always 0)
G.max is maximum possible value in the global score range (always 100)
P.PR is the priority given to the partner technology.
F.P is the transformed score for the partner technology, taking into account the Priority.
F.P = (P.x - P.min) * ((G.max - G.min) / (P.max - P.min)) * P.PR
Example for ThreatMetrix score of -50 priority 1.
F.P = (-50 - -100) * ((100 - 0)/(100 - -100)) * 1 F.P = +50 * (100/200) F.P = 25.
For Global score F.Px is the transformed score for partner x, taking into account the Priority.
Px.PR is the priority used for partner X
GS = ( F.P1 + F.P2 + FPn + ... ) / ( P1.PR + P2.P + Pn.PR + ... )
