Ryanair shouldn't be too alarmed about the determination of some travel companies to find ways round its reCaptcha security feature to continue to access its flights.
According to this report, some of the biggest brains out there have devoted valuable research time to cracking many of the codes but have not managed to get past Google-owned reCaptcha.
A team of researchers from Stanford Security Laboratory, using its automated Decaptcha tool, managed to crack 13 out of 15 of the most current schemes on sites including Visa's Authorize.net, CNN, Digg and eBay.
While the research concludes that Captcha's can be got around, leaving many sites open to attack, the researchers admit they were foiled by reCaptcha.
Interestingly, Authorize.net and Digg have now moved to reCaptcha according to the report.
Incidentally, and for anyone who didn't know, Captcha stands for Completely Automated Public Turing test to tell Computers and Humans Apart and was devised in 2000 by a team from Carnegie Mellon University.
