# Face Object

<table><thead><tr><th width="198">Attribute</th><th>Description</th></tr></thead><tbody><tr><td><strong>auditTrailImageId</strong></td><td>The selfie of the user that performed the facial recognition in case a manual review is needed for security and auditing purposes. See <a href="/pages/b9juEvkfh4v7shlSCGVb">Download a resource</a> for details on how to download the image.</td></tr><tr><td><strong>matchLevel</strong></td><td><p>Five accuracy settings are defined from 1 to 5 with accuracy lower or equal to 1 being the worst and greater or equal to 5 being the best.</p><ul><li>1: we do not recommend using this level, which is intended for really bad ID photos only.</li><li>2: still a relatively high false acceptance rate, should be the lowest acceptable level when using photo scans.</li><li>3: moderate accuracy level.</li><li>4: quite OK.</li><li>5: the identity can be seen as approved.</li></ul></td></tr><tr><td><strong>match</strong></td><td>The facial recognition matches the id photo of the document. If available, the id photo from the chip is taken, otherwise the id photo from the optical scanning is taken. It will always be true at this level; the process doesn’t continue if face doesn’t match all the documents provided. Unless you enable the feature to return the data for an incomplete session, in that case, if a face object exists, it could be false.</td></tr><tr><td><strong>oneToNVerificationId</strong></td><td>1:N face match verification id. It's essential to store this unique ID in your system alongside the user's record, facilitating future searches for users with the same ID. <br>Please be aware that this attribute is available only when oneToNVerification is enabled. This feature requires a specific permission, otherwise, it is disregarded</td></tr><tr><td><strong>oneToNVerificationMatch</strong></td><td>Indicates if there was a match with a previously onboarded selfie.<br>Please be aware that this attribute is available only when oneToNVerification is enabled. This feature requires a specific permission, otherwise, it is disregarded</td></tr></tbody></table>

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.uqudo.com/docs/kyc/uqudo-sdk/sdk-result/data-structure/face-object.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
