I need urgent help to implement a captcha function at this form
<[login to view URL]>
Visual appearance of the captcha need to be similar to this one
<[login to view URL]>
Which means no borders around like the reCAPTCHA.
The technology need to be up to date with the newer bots.
The project is very urgent and I will choose among the first bids. You need to be able to proceed immediately.
Please attach an image or link to the captcha function you can implement together with the bid.
