WinBioIdentify始终返回WINBIO_E_UNKNOWN_ID [英] WinBioIdentify always returns WINBIO_E_UNKNOWN_ID

问题描述

环境：

- 指纹传感器  WINBIO_SESSION_FLAGS as
WINBIO_FLAG_BASIC 。

- 使用私人泳池

- OS Windows 10

问题：注册成功，我可以使用WinBioEnrollCommit API提交数据。但是，当我使用WinBioIdentify验证指纹时，它返回错误代码  WINBIO_E_UNKNOWN_ID 0x80098003。 

如果我尝试注册已注册的手指，则WinBioEnrollCommit API将输出变量"IsNewTemplate"返回成功为0。即指纹模板已经存在。

当我使用其他具有&span; WINBIO_SESSION_FLAGS为
WINBIO_FLAG_ADVANCED ，  WinBioIdentify返回S_OK和
登记手指的身份。

对于具有  WINBIO_SESSION_FLAGS为
WINBIO_FLAG_BASIC ？

谢谢，

Denzz。

解决方案

感谢您在此处发帖。

>> WinBioIdentify是否有任何使用限制具有WINBIO_SESSION_FLAGS的设备的API为WINBIO_FLAG_BASIC？

当您设置  WINBIO_FLAG_BASIC标志时，生物识别单元仅作为基本捕获设备运行。所有处理，匹配和存储操作由软件插件执行。

WINBIO_FLAG_ADVANCED标志允许生物识别单位使用内部处理和存储功能。

这就是区别而已可能会导致WINBIO_E_UNKNOWN_ID错误。有关详细信息，请参阅以下文档。

Environment:

- Fingerprint sensor with WINBIO_SESSION_FLAGS as WINBIO_FLAG_BASIC.

- using private pool

- OS Windows 10

Issue: Enrollment is success and I could commit the data using WinBioEnrollCommit API. But, when I verify the fingerprint using WinBioIdentify, it returns error code WINBIO_E_UNKNOWN_ID 0x80098003. 

If I try to enroll the already enrolled finger, WinBioEnrollCommit API return success with output variable "IsNewTemplate" as 0. I.e. the fingerprint template already exists.

When I used another device which has WINBIO_SESSION_FLAGS as WINBIO_FLAG_ADVANCED, WinBioIdentify returns S_OK and identity of the enrolled finger.

Is there any usage limitation for WinBioIdentify API with devices having WINBIO_SESSION_FLAGS as WINBIO_FLAG_BASIC?

Thanks,

Denzz.

Hi,

thanks for posting here.

>>Is there any usage limitation for WinBioIdentify API with devices having WINBIO_SESSION_FLAGS as WINBIO_FLAG_BASIC?

When you set the WINBIO_FLAG_BASIC flag, the biometric units operate only as basic capture devices. All processing, matching, and storage operations is performed by software plug-ins.

The WINBIO_FLAG_ADVANCED flag lets the biometric units use internal processing and storage capabilities.

That's the difference and it may cause the WINBIO_E_UNKNOWN_ID error. For more information, please refer to this document below.
