CAPTCHAs were once considered proof (or at least an excellent defense) against the likes of spammers and automated registration programs, but those days appear to be almost over. CAPTCHA-cracking is now big business in India, and a means of gainful (if not quite legitimate) employment. Read More... ...

Archivists are trying to digitize many old and distorted texts and frequently are confronted with the failure of software to recognize words. Researchers are now presenting the results of a successful method for identifying these words: turn the scanned text into a CAPTCHA. Read More... ...

Charlie Demerjian the Inquirer , Sunday 10 August 2008. 19:23:00 Defcon 2008 Annoys users, not bots THERE WERE TWO talks on CAPTCHAs at Defcon 16, and they both said the same thing, CAPTCHAs are pointless and stupid. This was backed up with a lot of science and code, but the end result is the same, if you have a clue and some time, you can break... ...

Just about all the forms on LISNews currently use a simple text Captcha for obvious reasons. Yesterday I received a report of Captcha trouble that I just can't replicate. Is anyone else unable to make it past the Captcha challenges here on LISNews? (If you can't make it past the Captcha on this post, or the contact form to tell me about the problems(yes, irony, I know), you can email me directly btcarver and the domain is lisnews.com.) ...

After our CAPTCHAs Discussion the other day I decided to give Mollom a try. Mollom is a web service that analyzes the quality of content posted to websites. This includes comments, contact-form messages, blogs, forum posts, etc. Mollom specifically tries to determine whether this content is unwanted - i.e. "spam" - or desirable - i.e. "ham." Please let me know if you have troubles commenting or using any of the other forms now! ...

Si te has creado alguna cuenta recientemente en alguna página de internet, seguro que te has encontrado CAPTCHAs, que impiden que se puedan dar de alta masivamente desde máquinas. Y son realmente útiles, sin embargo no siempre están pensados para favorecer al usuario su contenido, y a las pruebas me remito: Noticias Relacionadas:Password suggest, generador de contraseñas¿Para [...] ...

CAPTCHAs are annoying. Half of the implementations that have you type in something from the image are unreadable for my eyes. I am sorry that I have to use them on my own blog. This one though, makes it very tough. I had this on my own MT blog back in the day, when the code [...] ...

Les textes et les livres qui se décomposent sur les étagères poussiéreuses des musées vont bientôt retrouver des yeux pour les lire, et ce bizarrement, grâce au concours d’un outil anti-spam. Il n’est pas nouveau que les sites participatifs utilisent des caractères d’allure étrange pour distinguer entre les utilisateurs humains et leurs pâles imitateurs algorithmiques. Mais [...] ...

Luis von Ahn, the Carnegie-Mellon professor who invented the Captcha system that helps identify you as a human instead of a spamming computer, has rolled out a system that uses words from newspapers and books that the Internet Archive and others are scanning in. OCR software can't read a lot of old text. So this system reads sends these words for us to translate when we log in to comment on blogs or buy from Ticketmaster. Read about it in WSJ.com: Web-Security Inventor Charts a Squigglier Course By Ethan Smith Word Count: 946 | Companies Featured in This Article: Google, IAC/InterActiveCorp, Microsoft, Yahoo, New York Times PITTSBURGH -- The system of squiggly characters that must be typed correctly to gain access to certain Web sites has annoyed online users for years. Now, the primary inventor of the security technique wants to make amends -- by making Web users decipher even more squiggly words. Luis von Ahn devised the system of distorted images of letters and numbers in 2000 as a way for email providers, online ticket sellers and other Web services to weed out online undesirables such as computerized ticket scalpers and spammers. The droopy characters, called CAPTCHAs, are irritating to humans, but are usually indecipherable ... ...

I recently attended a talk where the authors claimed that the CAPTCHA technology (the squiggly letters they make you type in whenever you sign up for anything) is dead and defeated. I disagree. In the talk, they demonstrated how to break a couple of “home-brew” captcha-implementations they found on the internet. Most of them were [...] ...

I hate CAPTCHAs. I know they're an effective way of fooling the form filling bots but they slow down surfing and are often very hard to read. Now however, there's reCAPTCHA reCAPTCHA: Stop Spam, Read Books (http://recaptcha.net/) a service that sends out hard to read words from old books and articles that OCR has trouble with and uses the results to digitize the original work. I think that's a brilliant idea because it serves two useful purposes in one go and with that in mind I'm less likely to complain about them. I may even use them instead of hand filtering the junk that comes from my various forms. Anyone had any experience using them? ...
