03.2024 - Recommended Thresholds
Fusion Thresholds
When implementing the thresholds outlined below, users should not use the Fuse Results activity.
Front-side thresholds:
The recommended approach to document authentication is to perform document authentications for the front side of documents in the following combination of authentication algorithms with the following thresholds.
| Color Copy Detection 1.3.0 | Black and White Copy Detection | Photo Substitution Detection 1.4.1 | Screen Replay Detection 2.2.0 | Paper Copy Detection 2.2.0 | Portrait Substitution Detection 2.2.0 | |
|---|---|---|---|---|---|---|
| Threshold | 0.02 | 0.0096 | 0.0036 | 0.3279 | 0.2191 | 0.3333 |
| Supported Pipelines | NA | NA | NA | ibis-sr | penguin-pc | quail-ps |
Back-side thresholds:
In the case where the updated algorithms are to be applied to backside the following combination is recommended. The recommendation is to remove:
- Black and White Copy Detection
- Photo Substitution Detection
- Portrait Substitution Detection
| Color Copy Detection 1.3.0 | Screen Replay Detection 2.2.0 | Paper Copy Detection 2.2.0 | |
|---|---|---|---|
| Threshold | 0.02 | 0.3279 | 0.2191 |
| Supported Pipelines | NA | ibis-sr | penguin-pc |
Default Thresholds
When a customer first drag an activity from the screen we need to also have thresholds in place, these however will differ from the fusion thresholds. By default the activities will have the following standalone thresholds. These thresholds would need to be adjusted if using in combination with any other algorithm:
Note Color Copy Detection v1.3.0 is not recommend for use outside of a fusion context due to its BPCER.
| Color Copy Detection 1.3.0 | Black and White Copy Detection | Photo Substitution Detection 1.4.1 | Screen Replay Detection 2.2.0 | Paper Copy Detection 2.2.0 | Portrait Substitution Detection 2.2.0 | |
|---|---|---|---|---|---|---|
| Threshold | 0.04 | 0.014 | 0.007808 | 0.13572 | 0.5 | 0.5 |
| Supported Pipelines | N/A | N/A | N/A | ibis-sr | penguin-pc | quail-ps |
