Extension BiometricSyntax (RFC 3039).

Documentation from RFC 3039:

This section defines an extension for storage of biometric information. Biometric information is stored in the form of a hash of a biometric template.

The purpose of this extension is to provide means for authentication of biometric information. The biometric information that corresponds to the stored hash is not stored in this extension, but the extension MAY include an URI pointing to a location where this information can be obtained. If included, this URI does not imply that this is the only way to access this information.

It is RECOMMENDED that biometric information in this extension is limited to information types suitable for human verification, i.e., where the decision of whether the information is an accurate representation of the subject is naturally performed by a person. This implies a usage where the biometric information is represented by, for example, a graphical image displayed to the relying party, which MAY be used by the relying party to enhance identification of the subject.

This extension MUST NOT be marked critical.

ASN.1 definitions:

      biometricInfo  EXTENSION ::= {
          SYNTAX             BiometricSyntax
          IDENTIFIED BY      id-pe-biometricInfo }

      id-pe-biometricInfo OBJECT IDENTIFIER  ::= {id-pe 2}

      BiometricSyntax ::= SEQUENCE OF BiometricData

      BiometricData ::= SEQUENCE {
          typeOfBiometricData  TypeOfBiometricData,
          hashAlgorithm        AlgorithmIdentifier,
          biometricDataHash    OCTET STRING,
          sourceDataUri        IA5String OPTIONAL }

      TypeOfBiometricData ::= CHOICE {
          predefinedBiometricType    PredefinedBiometricType,
          biometricDataID            OBJECT IDENTIFIER }

      PredefinedBiometricType ::= INTEGER { picture(0),
          handwritten-signature(1)} (picture|handwritten-signature,...)

The predefined biometric type picture, when present, SHALL identify that the source picture is in the form of a displayable graphical image of the subject. The hash of the graphical image SHALL only be calculated over the image data excluding any labels defining the image type.

The predefined biometric type handwritten-signature, when present, SHALL identify that the source data is in the form of a displayable graphical image of the subject's handwritten signature. The hash of the graphical image SHALL only be calculated over the image data excluding any labels defining the image type.
