New-DlpFingerprint
This cmdlet is available only in Security & Compliance PowerShell. For more information, see Security & Compliance PowerShell.
Use the New-DlpFingerprint cmdlet to create document fingerprints that are used with data loss prevention (DLP) sensitive information types in the Microsoft Purview compliance portal. Because the results of New-DlpFingerprint aren't stored outside of the sensitive information type, you always run New-DlpFingerprint and New-DlpSensitiveInformationType or Set-DlpSensitiveInformationType in the same PowerShell session.
For information about the parameter sets in the Syntax section below, see Exchange cmdlet syntax.
Syntax
Default (Default)
New-DlpFingerprint
[[-FileData] <Byte[]>]
-Description <String>
[-IsExact <Boolean>]
[-Confirm]
[-ThresholdConfig <PswsHashtable>]
[-WhatIf]
[<CommonParameters>]
Description
Sensitive information type rule packages are used by data loss prevention (DLP) to detect sensitive content in messages.
To use this cmdlet in Security & Compliance PowerShell, you need to be assigned permissions. For more information, see Permissions in the Microsoft Purview compliance portal.
Examples
Example 1
$Patent_Template = [System.IO.File]::ReadAllBytes('C:\My Documents\Contoso Patent Template.docx)'
$Patent_Fingerprint = New-DlpFingerprint -FileData $Patent_Template -Description "Contoso Patent Template"
This example creates a new document fingerprint based on the file C:\My Documents\Contoso Patent Template.docx. You store the new fingerprint as a variable so you can use it with the New-DlpSensitiveInformationType cmdlet in the same PowerShell session.
Parameters
-Confirm
Applicable: Security & Compliance
The Confirm switch specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.
- Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax:
-Confirm:$false. - Most other cmdlets (for example, New-* and Set-* cmdlets) don't have a built-in pause. For these cmdlets, specifying the Confirm switch without a value introduces a pause that forces you acknowledge the command before proceeding.

-FileData
Applicable: Security & Compliance
The FileData parameter specifies the file to use as a document fingerprint.
A valid value for this parameter requires you to read the file to a byte-encoded object using the following syntax: ([System.IO.File]::ReadAllBytes('<Path>\<FileName>')). You can use this command as the parameter value, or you can write the output to a variable ($data = [System.IO.File]::ReadAllBytes('<Path>\<FileName>')) and use the variable as the parameter value ($data).
