Hotmail, Yahoo! erect roadblocks for spam sign-ons | |

Thanks, Jaz The idea is to use a form of Turing Test to distinguish humans for Web robots, called captchas (completely automated public Turing tests to tell computers and humans apart). Gimpy, one on these captchas, selects a word from a dictionary and mangles its image in a way that is obvious to humans to interpret but confuses a machine. Yahoo! began using Gimpy last year to block bots from creating email accounts. This month, Hotmail plans to introduce a similar system, according to wire reports. | ||
