I need to add a feature where every invoice my asp.net solution needs to be signed digitally by the person making the invoice. So my client wants the option that rather than signing digitally using a mouse, they want the person making the invoice to put in their fingerprint.
How can I get the finger print of a person in my web page using javascript.
Your question is about digitally signing and using JavaScript to do this.
I think accessing finger print scanners may not be possible, many devices simply don't have finger print scanners let alone have access to them via JavaScript.
What I would suggest instead is looking at what JavaScript makes available and how useful this is as digital signing. For our work we just required that the user type in their name (and displayed it in a fancy handwriting font) and that was enough. But you could do better than this by accessing the web cam or mike via JavaScript. You could then get either...
The above methods have a number of draw backs, the main one being you can't validate that the user was actually in the photo (they could hold up a magazine image in front of the webcam) but this is true of many signing methods (written signature on paper can be anything).
If you wanted to go down the finger print route you could then process the image (from the web cam) of a finger print, although this would be fairly complex.
