Creativity to solve security issues
The Internet Storm Center had a growing problem with form spam but wanted to avoid using captchas, so they decided to use creativity. Their solution is one great way to separate machines and humans when they fill out the forms – but their readers came up with a few more that also got posted that are even more interesting.
The common thread in all the solutions is that computers are very literal and find it hard to be flexible, and humans cannot help but be flexible. I have dealt with enough captchas – and struggled with some, and failed some – that I think these ideas are wonderful from a user’s standpoint. Plus, as the ISC post states:
