Remarks

This standard uses the term template to refer to the biometrics enrollment data for a user. The term BiometricsInformationRecord refers to any biometrics data that is returned to the application; including raw data, intermediate data, processed samples ready for verification or identification, and enrollment data. Typically, the only data that is stored persistently by the application is the BiometricsInformationRecord generated for enrollment, such as the template. The format of the opaque Biometric Data Block is indicated by the Format field of the Header. This may be a standard or proprietary format. The Biometric Data Block may be encrypted. The digital signature is optional, and may be used to verify integrity of the data during transmission and storage. When present, it is calculated on the header + Biometric Data Block.

For standardized BiometricsInformationRecord formats, the signature takes a standard form (to be determined when the format is standardized). For proprietary BiometricsInformationRecord formats (all that exists currently), the signature can take any form that suits the Service. Therefore, there is no C structure definition of the signature. The BiometricsInformationRecord Data Type indicates whether the BiometricsInformationRecord is signed and encrypted or only encrypted. Processed biometrics data obtained through the methods BeginEnrollCapture, BeginVerifyCapture, and Verify are stored in this property upon their successful completion.

Any public static (Shared in Visual Basic) members of this type are thread-safe. Any instance members are not guaranteed to be thread-safe.
