[Standards] CAPTCHAs in registration forms

Hey Peter,

XEP-4 defines a few field types. I think that we should create a new field type for media objects so that clients could render it appropriately.

I like the media element that you included in the data form. I think that servers may choose to include the image itself in the form field or provide a URI to get it.

I think I would expect the completed form to include a reply to the media field. In this case it would include the CAPTCHA value. Another choice, would be to just use the media field as a read-only field and then have another text field where the user could enter his CAPTCHA value.

Am I missing something here?

In order to fight abuse on the network, we need (among other things!)
CAPTCHAs and other computational puzzles in account registration forms:


But for that we need to figure out how to include media objects in data
forms. One proposal is XEP-0221:


However, in the last XMPP Council meeting Ralph Meijer raised some
concerns about including media directly in forms:


I tend to agree with Ralph, but we need to figure this out soon. So
let's discuss. :)
