VouchSafe Spam Prevention
Nobody likes CAPTCHAs.
Consumers hate CAPTCHAs because they're difficult to complete, and seem to offer no value to their experience. CAPTCHAs are just an obstacle to doing what you want to do.
Site operators had CAPTCHAs because they're just another barrier to consumer committment, and they're often ineffective at stopping spam.
We set out to create a completely new technology that would solve both these problems.
Image CAPTCHAs and Puzzles May Be Easy, but They're Not Secure
Some people have tried to replace CAPTCHAs with other kinds of tests that are easier for people to solve, by using photos, or puzzles or other gimmicks like sliders and “click and drag” tasks. The reason that these haven’t really caught on is that while they’re easier and more appealing than CAPTCHAs, they’re just not secure enough to protect the websites that spammers really go after. It’s not good enough just to make a test that’s easier for humans: we need something that’s easy to use, but more secure than current CAPTCHAs.
The VouchSafe Solution
We’ve created a new technology that uses an adaptive AI to create simple visual challenges that either require users to look at a collection of objects and find two of them that are related…Or to look at a set of related objects and find the thing that doesn’t belong. Th result is a solution that's easier for users to complete, and more secure than most CAPTCHAs.
We call our product VouchSafe for a varitey of reasons: vouchsafe is a memorable word, and its original meanings still have some resonance with people. But mostly, we call it VouchSafe because it makes sense to consumers. We like to say that we vouch for your traffic, to keep your web application safe from spammers.
The VouchSafe User Experience
VouchSafe is easy to use: users simply click on the “VouchSafe” button to expand the challenge… and then follow the instructions. VouchSafe includes features to help make the technology easier to use. For example, if you want, you can expand a challenge full-screen.
For users who are visually or motor-impaired, VouchSafe offers audio challenges that are accessible via keyboard shortcuts. As with our visual technology, we’ve made a commitment to creating challenges that are easy for people to solve.
The unique drawing action makes VouchSafe difficult to hack, and also makes it a natural fit for touch screen devices like smart phones or tablet computers.
