Upping the CAPTCHA ante
- mike-cardwell 16y agoCan't imagine why they used a flash video instead of an animated gif.
- garyrichardson 16y agoIt's not flash video, it's h264. GIF's are far larger and lower resolution for the same videos. If you turn off javascript or flash when visit the page, you will actually see a gif version.
- tptacek 16y agoWho cares? Captcha-solving is a solved problem. If you have an illicit business model that has captchas as an obstacle, contracting out actual humans in third-world companies to bypass that obstacle adds pennies to your overhead. It's almost scammy to suggest that real companies should be investing in better captchas.
- thraxil 16y agoIt seems to me that this would actually be easier for software to bypass than a regular image based CAPTCHA, it just consumes a bit more bandwidth. Pulling individual frames out of a video is simple, so you just pull a few frames out of the video and run your regular image CAPTCHA breaking algorithm on them. Since you've got multiple frames, your software has multiple attempts to compare which makes it even more robust. Meanwhile it doesn't solve any of the actual problems with CAPTCHAs that others mentioned.
