# Fingerprint mode

A [fingerprint](/senseml-reference/config-settings/fingerprint) for standalone documents changes Sensible's default behavior of running *all* the configs in a single document type. For example, if you extract company A and company B quotes, by default Sensible runs both the company A and the company B configs for a given document, then returns the extraction with the highest score.

The following tables show how this default behavior changes when you configure the following levels of strictness for a document type's fingerprints. You can configure strictness in the Sensible app in the document type settings tab.

### Single-document file fingerprints

| Strictness level | Description                                                                                                                                                     | If more than one config's tests pass over 50%                                   | If no configs' tests passes over 50% or if no configs contain a fingerprint                                                                                     |
| ---------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| standard         | If any of the configs in the document type contain a fingerprint, then Sensible runs extractions using any configs that pass over 50% of the fingerprint tests. | Sensible chooses the output from the passing config with the highest score      | Sensible falls back to the default behavior of running extractions for the document using *all* configurations, and returns the one that has the highest score. |
| strict           | The doc type must have at least one config containing a fingerprint.                                                                                            | Sensible chooses the output from the passing config that has the highest score. | Sensible returns a 400 error.                                                                                                                                   |

In the preceding table, Sensible calculates a score as follows:

`classification score` = `num of non-null fields` <br />- `penalties for validation errors or warnings`, where penalties are as follows:

* `validation error penalty` = 1 \* `num fields with validation errors```* `validation warning penalty`\= 0.5 \*`num of fields with validation warnings\`\`\`
  The classification score is for comparing extractions within a single document type. To compare scores across document types, see [Accuracy measures](/senseml-reference/concepts/accuracy-measures).

### Portfolio fingerprints

When using fingerprints for segmenting portfolio files into documents, Sensible ignores the document type's fingerprint mode setting.
