Fusion Thresholds
When implementing the thresholds outlined below, users should not use the Fuse Results activity.
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 1.4.0 | Black and White Copy Detection 2.1.0 | Photo Substitution Detection 1.5.0 | Screen Replay Detection 2.5.0 | |
|---|---|---|---|---|
| Threshold | 0.2 | 0.6667 | 0.2 | 0.2 |
| Supported Pipelines | NA | NA | NA | vulture-sr |
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 1.4.0 | Black and White Copy Detection 2.1.0 | Screen Replay Detection 2.5.0 | |
|---|---|---|---|
| Threshold | 0.25 | 0.375 | 0.2 |
| Supported Pipelines | NA | NA | vulture-sr |
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 1.4.0 | Black and White Copy Detection 2.1.0 | Photo Substitution Detection 1.5.0 | Screen Replay Detection 2.5.0 | |
|---|---|---|---|---|
| Threshold | 0.6667 | 0.375 | 0.2 | 0.2 |
| Supported Pipelines | NA | NA | NA | vulture-sr |
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 1.4.0 | Black and White Copy Detection 2.1.0 | Screen Replay Detection 2.5.0 | |
|---|---|---|---|
| Threshold | 0.9167 | 0.375 | 0.2 |
| Supported Pipelines | NA | NA | vulture-sr |
Default Thresholds
When a customer first adds an activity to a Process Definition from the Activity pallet, the activity will have default standalone thresholds i.e., thresholds that would be applied if the activity is to be used without combining with other activities. If using in combination with any other algorithm these thresholds would need to be adjusted. What follows below are all the default standalone thresholds:
| Color Copy Detection 1.4.0 | Black and White Copy Detection 2.1.0 | Photo Substitution Detection 1.5.0 | Screen Replay Detection 2.5.0 | Paper Copy Detection 2.5.0 | Portrait Substitution Detection 2.5.0 | |
|---|---|---|---|---|---|---|
| Threshold | 0.7245 | 0.9321 | 0.9057 | 0.1252 | 0.5 | 0.3623 |
| Supported Pipelines | N/A | N/A | N/A | vulture-sr | woodpecker-pc | umbrellabird-ps |
