XML format of PID block

[Gaurav sharma]

Dear UIDAI

The XML format mentioned in "adhaar registered device api-2.0" 

<PidData> 

    <Resp errCode="" errInfo="" fCount="" fType="" iCount="" iType="" pCount="" pType="" nmPoints="" qScore=""/> 

    <DeviceInfo /> 

    <Skey ci="">encrypted and encoded session key</Skey> 

    <Hmac>SHA-256 Hash of Pid block, encrypted and then encoded</Hmac> 

    <Data type="X|P"> base-64 encoded encrypted pid block </pid> 

</PidData> 

 

As we understand the "bs" and "dih" is not mentioned in the xml format.

As our team suggested that the last line should contain

 <Data type="X/Y"/><pid>pid block</pid>      

              instead of  

<Data type="X|P"> base-64 encoded encrypted pid block </pid> .

(pid block should have "bs" and "dih") 

please confirm it that whether we are right or not if not then please correct us. 

[Netaji Rao]

Dear Gourav,

</Pid> would be a typo, need to be </Data>.

Remaining things are correct. Please refer authentication API v2.0 doc for Pid block format.

Dear Netaji Rao

thanks for the reply

will you please provide us some example of the xml required to generate the pid block for RD service because in authentication document there are a lot of other fields  also

<Pid ts="" ver="" wadh=””>  

 <Demo lang="">    

 <Pi ms="E|P" mv="" name="" lname="" lmv="" gender="M|F|T" dob="" dobt="V|D|A" age="" phone="" email=""/>  

   <Pa ms="E" co="" house="" street="" lm="" loc=""          vtc="" subdist="" dist="" state="" country="" pc="" po=""/>   

  <Pfa ms="E|P" mv="" av="" lav="" lmv=""/>

   </Demo>

   <Bios dih="">   

  <Bio type="FMR|FIR|IIR|FID" posh="" bs="">encoded biometric</Bio>

   </Bios> 

  <Pv otp="" pin=""/> 

 </Pid> 

 

 we was tried to send this format for pid but it gives us an error

so please suggest us a proper format for pid block

[Netaji Rao]

Dear Gaurav,

Assuming you are using a fingerprint device and FMR. Below would be the pidblock format when Demograohics and OTP are not part of your auth request.

<Pid ts="" ver="" wadh=””>  

   <Bios dih="">   

  <Bio type="FMR" posh="" bs="">encoded biometric</Bio>

   </Bios> 

 </Pid> 

Thanks,
Netaji Rao D

Dear Netaji Rao

Thanks for the revert

what element should be passed in the  place of "encoded biometric" within pid block?

Please check the whole xml format and if there is any mistake then correct us

Is the whole format of XML is

<PidData> 

    <Resp errCode="" errInfo="" fCount="" fType="" iCount="" pCount=""/> 

    <DeviceInfo /> 

    <Skey ci="">encrypted and encoded session key</Skey> 

    <Hmac>SHA-256 Hash of Pid block, encrypted and then encoded</Hmac> 

    <Data type="X|P"> base-64 encoded encrypted pid block </data> 

<Pid ts="" ver="" wadh=””>  

   <Bios dih="">   

  <Bio type="FMR" posh="" bs="">encoded biometric</Bio>

   </Bios> 

 </Pid> 

</PidData>

or

<Pid ts="" ver="" wadh=””>  

   <Bios dih="">   

  <Bio type="FMR" posh="" bs="">encoded biometric</Bio>

   </Bios> 

 </Pid> 

this will generate the  base-64 encoded encrypted pid block 

and we have to put it here

<PidData> 

    <Resp errCode="" errInfo="" fCount="" fType="" iCount="" pCount=""/> 

[Netaji Rao]

Dear Gaurav,

Encoded biometric is Base64 encoded FMR or IIR. Below is the right format for PidData XML.

<PidData> 

    <Resp errCode="" errInfo="" fCount="" fType="" iCount="" pCount=""/> 

    <DeviceInfo /> 

    <Skey ci="">encrypted and encoded session key</Skey> 

    <Hmac>SHA-256 Hash of Pid block, encrypted and then encoded</Hmac> 

    <Data type="X|P"> base-64 encoded encrypted pid block </Data> 

</PidData> 

Thanks,
Netaji Rao D

Hi,

    Can you provide FIR PID Block Implementation.

    From Our Device we get 2 type of Data 1: Template Data (Usually used for Authentication)   2: WSQ Image Data

    My question is Where to put WSQ Image Data.

which data to put in encoded biometric section 1:Template Data or 2 : WSQ Image.

<Bio type="FMR|FIR|IIR|FID" posh="" bs="">encoded biometric</Bio>    

     

<Pid ts="" ver="" wadh=””>  

 <Demo lang="">    

 <Pi ms="E|P" mv="" name="" lname="" lmv="" gender="M|F|T" dob="" dobt="V|D|A" age="" phone="" email=""/>  

   <Pa ms="E" co="" house="" street="" lm="" loc=""          vtc="" subdist="" dist="" state="" country="" pc="" po=""/>   

  <Pfa ms="E|P" mv="" av="" lav="" lmv=""/>

   </Demo>

   <Bios dih="">   

  <Bio type="FMR|FIR|IIR|FID" posh="" bs="">encoded biometric</Bio>

   </Bios> 

  <Pv otp="" pin=""/> 

 </Pid> 

 

Please, can anybody help us about what will be the use case of FIR request?

Is FIR used in every PID block authentication query?

Hi,

Your fingerprint scanner manufacturer should be able to provide SDK for FIR.

Or else, ISO 19794-4 doc helps in creating FIR with WSQ image.

Thanks,

[aakashja...@gmail.com]

Hi,

can you provide me  ISO 19794-4 doc   also we get 1: template and 2: wsqimage so out of these two i am using WSQ data in BIOS Tag as below :

byte[] template = hexStringToByteArray(templatestr);    // This one i am not using its template data used for authenticaion etc

 // below Fingerprint Image Data if we write  finalwsq  data in file we can view fingerprint image in WSQ Viewer  

byte[]  finalwsq  = myhexToASCII(hexwsqdata.getBytes());  

bioCapture = new BioCaptureDeviceInfo();
bioCapture.setIsoBytes(finalwsq);
bioCapture.setBh(generateHash(finalwsq));
bioCapture.setNmPoints(getMinutiaeCount(finalwsq));

so can you please confirm above way is correct or not
