DigitalPersona SDK

Hi Guys,
I'm trying to use DigitalPersona SDK to use biometric readers in our program. I already had sucess to read and save a fingerprint.
The problem is I'm not having sucess to verify a saved fingerprint. There is in the DPFPEngX.DLL of the SDK a object that perform this verification, but I don't know how to use it in FWH.
The object is:

DPFPVerification
The DPFPVerification object performs the system function of fingerprint verification, which is a one-toone comparison of a fingerprint feature set with a fingerprint template produced at enrollment that returns a decision of match or non-match.

Verify Method
Performs the system function of fingerprint verification and specifies a comparison decision based on the
requested FAR set by the FARRequested property.

Syntax
Dim oVerificationResult As DPFPVerificationResult
Set oVerificationResult = object.Verify(
ByVal oVerificationFeatureSet As Object,
ByVal oFingerprintTemplate As Object)

Could you help me ?

Thanks Karinha,

I'm trying to do it using this:

Code: Select all  Expand view
oTem := CreateObject("DPFPShrX.DPFPTemplate.1")
oTem:DESERIALIZE( oRec:Bio )


But now I'm having this error:
Code: Select all  Expand view
(DOS Error -2147352567) WINOLE/1007  Tipo de variável incorreto. (0x80020008): DPFPShrX.DPFPTemplate.1

I think it's happening because field BIO is an ARRAY OF BYTES that I saved in a BLOB field.

Se entendi...
If i understood:

Code: Select all  Expand view

// DPFPEngX.DLL
#DEFINE DLL_STRING_OLE "DPFPEngX"

   #IFDEF __XHARBOUR__

       TRY

          oDpfpEngX := GetActiveObject( DLL_STRING_OLE )

       CATCH

         TRY

            oDpfpEngX := CreateObject( DLL_STRING_OLE )

         CATCH

            MsgStop( "ERROR!",  "ERROR!" )

         END

      END

   #ELSE

      oDpfpEngX := TOleAuto():New(DLL_STRING_OLE)

      IF oDpfpEngX:hObj == 0

         MsgStop( "ERROR!",  "ERROR!" )

      ENDIF

   #ENDIF
 


Regards.

Thanks Karinha,
But it 'isn't what I need.
I'm creating the object DPFPVerification from this way:

Code: Select all  Expand view
oTem := CreateObject("DPFPShrX.DPFPTemplate")


The problem is happening when I try to do this:
Code: Select all  Expand view
oTem:DESERIALIZE( oRec:Bio )


I think it's is happening because oRec:Bio is a BLOB Field, and Deserialize() wants a vbasic BYTEARRAY.

Não entendo o que você quer fazer Vilian, pois é algo novo. Você já viu:
I don't understand what you want to do Vilian, as it is something new. Have you seen:

Code: Select all  Expand view

  HB_Serialize()
  e
  HB_DeSerialize()

Karinha,

Eu estou tentando usar o SDK do leitor de biometria DgitialPersona!
I'm trying to use the SDK of the DigitalPersona's reader!

Ele deve ser novo no mercado, pois não tem nenhuma documentação sobre o mesmo.

Veja se ele não tem a mesma lógica do SDK da Griaule:

Este SDK é o do próprio fabricante do leitor. Quando vc compra, vem junto com o equipamento, então não teria custo adicional para o cliente. Esse da Griaule tem que comprar as licenças e é bem caro!

Vilian, como ele(leitor) é nacional, o melhor, é você criar um tópico no http://www.pctoledo.com.br/forum/, creio terás mais chances de ajuda por lá. Abs.

A few years ago I purchased digitalpersona finger, a kind of mouse where I can put my thumb, in my package there is a disk with many examples in different programming languages, a long time ago I asked on this forum without ever having had help on the matter . So I tell you that I would also be interested in using the machine to access my programs.
Griaule sources harbour are not compatible with digitalpersona

Silvio, does it come with Visual Basic examples?

Or any examples similar to xHarbour?

Did you manage to use it under Fivewin?

Thank you.
