accessing fingerprint image from windows store app

Question

I want to access the raw fingerprint scan (image) from my windows store app. How can we do it?

I used a .net assembly in my desktop app but it seems I can no longer invoke it from a windows store app.

Any pointers appreciated.

Answer 1

Hi Rahulforaim,

Could you tell us what is your purpose for access the fingerprint image?

We do have fingerprint feature in Windows Store App but it only used to do authentication: How to provide fingerprint (biometric) authentication, as we know UserConsentVerifier.RequestVerificationAsync method is the one that can request user consent from a fingerprint scan.

Answer 2

Thanks for looking into this james

think of it as data collection terminal. Similar to what we do during visa/ passport registration offices where we just collect fingerprints. It is not used for authentication. And yes I already looked into the API that you mentioned which is not useful n this scenario

Answer 3

What I can find from MSDN: WinBioCaptureSample, but this API is used only with desktop but not windows store app, I'm afraid we can not do the same thing in Windows Store App.

However if your app is a enterprise app instead of publishing to the store, that could be possible by Brokered Windows Runtime Components for side-loaded Windows Store apps , take a look at the Prashant's blog: http://blogs.msdn.com/b/wsdevsol/archive/2014/04/14/cheat-sheet-for-using-brokered-windows-runtime-components-for-side-loaded-windows-store-apps.aspx
