Plugin Description
VouchSafe is an easy, effective replacement for comment and registration CAPTCHAs that’s highly secure, and easier for your users to complete.
You can use VouchSafe to secure your comments and registration from spam. VouchSafe is easy to use, and very effective in stopping spammers. It’s the first Human Interactive Proof that use an adaptive AI to create challenges that only humans can solve. You can learn more about VouchSafe at the VouchSafe website.
To solve a challenge, users either draw a line to join two objects that are related, or circle one object that doesn’t belong in a group of related objects.
For visually or motor-impaired users, VouchSafe offers audio-based type-in challenges. VouchSafe is compatible with most smart phones and tablet computers.
VouchSafe requires users to register their domain to get an API key to activate their plugin. Your keyset allows you to customize the way VouchSafe will appear on each domain you manage. VouchSafe also offers support for SSL.
