03.2024 - Recommended Thresholds

Fusion Thresholds

Info

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:

Info

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
