NAME
    Get-BWSIsEnrolled

SYNOPSIS
    Finds out whether a user is already enrolled for a specific trait.


SYNTAX
    Get-BWSIsEnrolled [-BWS] <string> [-Certificate] <X509Certificate> [-BCID] <string> [-Trait <{Face | Periocular |
    Voice}>] [<CommonParameters>]


DESCRIPTION
    Sometimes it is useful to know whether there is a template available for a specific user and trait before a client
    tries to perform a verification of this user using this trait. If no template is available, i.e. the user is not
    yet enrolled, the client could use another authentication mechanism and send the user to the enrollment procedure.


PARAMETERS
    -BWS <string>
        Specifies the BioID Web Service (BWS) installation where the command shall be executed. You can simply use the
        hostname like 'bws.bioid.com' or the entire URL, e.g. 'https://bws.bioid.com/BioIDWebService.svc'. If scheme
        and/or path are not given, the defaults (https, BioIDWebService.svc) are used.

        Required?                    true
        Position?                    1
        Default value
        Accept pipeline input?       false
        Accept wildcard characters?  false

    -Certificate <X509Certificate>
        Specifies the client certificate that is used to authenticate the BWS client. Enter a variable that contains a
        certificate or a command or expression that gets the certificate.

        To find a certificate, use Get-PfxCertificate or use the Get-ChildItem cmdlet in the Certificate (Cert:)
        drive. For example:
        get-childitem -path Cert:\CurrentUser\My\1234567890ABCDEF1234567890ABCDEF12345678

        If the certificate is not valid or does not have sufficient authority, the command fails.

        Required?                    true
        Position?                    2
        Default value
        Accept pipeline input?       false
        Accept wildcard characters?  false

    -BCID <string>
        The Biometric ClassID (BCID) of the class for which to find out whether it is enrolled already or not. A class
        is an anonymous entity representing all the biometric data associated with a single individual.

        The BCID is a combination of a string, a partition id and the class id itself. The string specifies the
        Storage, e.g. the Windows Azure Storage Service to use, whereas the partition and class id is used within this
        storage to address the class.

        Required?                    true
        Position?                    3
        Default value
        Accept pipeline input?       false
        Accept wildcard characters?  false

    -Trait <BioID.Trait>
        The biometric trait for which to look for a template belonging to the specified person.

        Face
            The face trait.

        Periocular
            The periocular (eye) trait.

        Voice
            The voice trait.

        Required?                    false
        Position?                    named
        Default value                Face
        Accept pipeline input?       false
        Accept wildcard characters?  false

    <CommonParameters>
        This cmdlet supports the common parameters: Verbose, Debug,
        ErrorAction, ErrorVariable, WarningAction, WarningVariable,
        OutBuffer, PipelineVariable, and OutVariable. For more information, see
        about_CommonParameters (https:/go.microsoft.com/fwlink/?LinkID=113216).


OUTPUTS
    bool
        Returns true if a template for the specified class and trait is available, i.e. a verification of the user is
        possible. Returns false when a template for the specified class and trait was not found, i.e. a verification
        of the user is not possible. In this case the user needs to enroll the specified trait before performing any
        biometric action on this trait.


    -------------------------- EXAMPLE --------------------------

    $cert = get-childitem -path Cert:\CurrentUser\My\1234567890ABCDEF1234567890ABCDEF12345678
    Get-BWSIsEnrolled -BWS bws.bioid.com/BioIDWebService.svc -Certificate $cert -BCID bws.123.12345

    Detects whether the class bws.123.12345 is enrolled for the face trait.
