Cool idea, but how does it work against spambots? That's the whole point of CAPTCHA. It's not supposed to be a place to add marketing copy. It's supposed to ensure actual humans are using your service. This seems like it's going to be incredibly simple to hack given that the letters are crisp and easily read. I do see that the example CAPTCHA "ads" differ from company to company, but there are still basically 3-4 plain text words in the graphic. If I were making a spambot, I would need to try submitting it 3-4 times until I find the word that works. Too easy...
- ihumanable 16y agoI'm thinking the same thing. Especially since it uses this quoted text thing, just write your spambot to look for those anchors and extract and OCR the inner text, done. It's a clever idea and maybe in the short article they couldn't fully explain how this works to defeat spam bots. I'd like to know more about it from a tech and sec perspective.
- revdinosaur 16y agoIn theory they could prompt advertisers to create distorted ads, simply requiring users to visually decode the brand name.
- pietrofmaggi 16y agoYes, but how many ads can you have? or you automatically generates a ton of variation of the same ads otherwise a spammer can just keep a dictionary with the ads images and the correct answer.
- IgorPartola 16y agoBetter yet, build up a list of quotes organized by the brand. How many taglines can Toyota have? So even if the quoted text is obfuscated differently each time (new font, new noise), you can teach your bot to recognize the company logo and try one of the few taglines they have.
