What Is the “first” in KeyCAPTCHA and Why to Have it Externally, i.e. Out of Control?
KeyCAPTCHA is the first free service providing a powerful anti-spam website protection through a new generation interactive CAPTCHA.
to be less self-debunking and more clear.
The word “interactive” is really synonym to “intrusive for a visitor”, in contrast to non-intrusive anti-spam solutions like filtering, honey-traps (honey-pots), etc. Except its anti-marketing (i.e. negative) nature, it does not convey any information since in reality KeyCAPTCHA should have been more specifically described as “DRAG’N'DROP” and/or “not requiring text typing” (non-Texting?) instead of vague and generic “interactive”. All visible (presented) to a visitor CAPTCHAs are really interactive in that they require user’s interactions like typing, drag’n'drop-ping, clicking, etc.
The word “free” means in reality, for external service, like KeyCAPTCHA.com, ”un-paid by a user”.
KeyCAPTCHA.com external service internals are not free for scrutiny (or reuse) like open sourced products
All known to me anti-spam services are either free of charge or provide free of charge options/versions in parallel to fee-based service. The latter is in no way different from keycaptcha.com service having both fee-based and free of charge options of its service.
Since it is ridiculous to tout an anti-spam service as “first free” , let me guess, that it is a simple way to assure that users of KeyCAPTCHA did not read about and do not care what they have installed
The idea of non-texting captcha was researched before KeyCAPTCHA (introduced in 2010) a lot, for example:
- Google’s rotCAPTCHA project in 2009,
- Microsoft’s ASIRRA project in 2007,
- Carnegie-Mellon School of Computer Scince’s PIX project in 2000,
- ALIPR in 2006
There are dozens open-source projects offering CAPTCHs based on idea of choosing/clicking an image, for example:
as well as DRAG’N'DROP CAPTCHAs, for example:
- AJAX FANCY CAPTCHA
that, IMO, avoid the main point of vulnerability existing in KeyCAPTCHA – that it is external centralized proprietary service out of control of webresource owner who installs it.
