07.2025 - Recommended Thresholds
Fusion Thresholds
When implementing the thresholds outlined below, users should not use the Fuse Results activity.
The listed configurations utilize the following services:
- Color Copy Detection v2.0.0
- Black and White Copy Detection v2.1.0.1
- Photo Substitution Detection v1.5.1
- Screen Replay Detection v3.3.0
Convenient Thresholds
Convenient thresholds provide document authentication that is biased toward end user convenience.
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 2.0.0 | Black and White Copy Detection 2.1.0.1 | Photo Substitution Detection 1.5.1 | Screen Replay Detection 3.3.0 | |
|---|---|---|---|---|
| Threshold | 0.5 | 0.5 | 0.5 | 0.2056 |
| Supported Pipelines | NA | NA | NA | screen-replay_2024-09 |
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 Photo Substitution Detection and apply thresholds as follows:
| Color Copy Detection 2.0.0 | Black and White Copy Detection 2.1.0.1 | Screen Replay Detection 3.3.0 | |
|---|---|---|---|
| Threshold | 0.4 | 0.2 | 0.2 |
| Supported Pipelines | NA | NA | screen-replay_2024-09 |
Secure Thresholds
Secure thresholds provide document authentication that is biased toward more secure document authentication.
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 2.0.0 | Black and White Copy Detection 2.1.0 | Photo Substitution Detection 1.5.1 | Screen Replay Detection 3.3.0 | |
|---|---|---|---|---|
| Threshold | 0.65 | 0.5 | 0.5 | 0.2056 |
| Supported Pipelines | NA | NA | NA | screen-replay_2024-09 |
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 Photo Substitution Detection and apply thresholds as follows:
| Color Copy Detection 2.0.0 | Black and White Copy Detection 2.1.0 | Screen Replay Detection 3.3.0 | |
|---|---|---|---|
| Threshold | 0.7 | 0.2 | 0.2 |
| Supported Pipelines | NA | NA | screen-replay_2024-09 |
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:
| Color Copy Detection 2.0.0 | Black and White Copy Detection 2.1.0.1 | Photo Substitution Detection 1.5.1 | Screen Replay Detection 3.3.0 | Paper Copy Detection 3.3.0 | Portrait Substitution Detection 3.3.0 | |
|---|---|---|---|---|---|---|
| Threshold | 0.5961 | 0.9321 | 0.8974 | 0.1252 | 0.5 | 0.3623 |
| Supported Pipelines | N/A | N/A | N/A | screen-replay_2024-09 | printed-copy_2025-05 | portrait-substitution_2024-05 |
