# 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>auditTrailImageIdChecksum</strong></td><td>Checksum of the image binary. The value has the format "sha256:&#x3C;digest>" with the prefix defining the cryptographic hash that was used, SHA-256 in this case.</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>
