WINBIO_CAPABILITIES

The WINBIO_CAPABILITIES structure is a DWORD bitmask that specifies the capabilities of the biometric device.


typedef ULONG WINBIO_CAPABILITIES, *PWINBIO_CAPABILITIES;

Remarks

WINBIO_CAPABILITIES can contain the values in the following table.

Biometric capability value Description

WINBIO_CAPABILITY_SENSOR

The device can collect biometric data.

WINBIO_CAPABILITY_MATCHING

The device can perform match operations.

WINBIO_CAPABILITY_STORAGE

The device can store biometric templates.

WINBIO_CAPABILITY_SECURE_STORAGE

The device can store secure data that is associated with a template. The secure data is only released with a positive match. The device must support at least the SHA-1 algorithm for secure hash computation to be used to store templates in the system pool.

WINBIO_CAPABILITY_PROCESSING

The device can process samples and turn them into biometric templates.

WINBIO_CAPABILITY_ENCRYPTION

The device supports encryption of samples and templates.

WINBIO_CAPABILITY_SIGNING

The device can sign captured data.

WINBIO_CAPABILITY_NAVIGATION

The device can be used as a navigation device. Some devices and drivers can capture data in a format that can be translated by a user-mode application into navigation events, much like a mouse.

WINBIO_CAPABILITY_INDICATOR

The device has an indicator that can be turned on or off.

WINBIO_CAPABILITY_VIRTUAL_SENSOR

The sensor adapter manages its own connection to the biometric hardware.

Note  This constant applies only for Windows 10 and later.
 

WINBIO_CAPABILITY_SECURE_SENSOR

The device supports security methods available in the WinBio engine adapter interface version 4.0 or later.

Note  This constant applies only for Windows 10 and later.
