It is more easily possible for humans to look at an image and pick out the patterns than a computer. This is</span><br style="position: relative; word-wrap: break-word;" /><span style="border: 0px; font-stretch: inherit; font-style: inherit; font-variant: inherit; font-weight: inherit; line-height: inherit; margin: 0px; padding: 0px; position: relative; vertical-align: baseline; word-wrap: break-word;">because computers lack the real intelligence that humans have by default. CAPTCHAs are implemented by presenting users with an image which contains distorted or randomly stretched characters which only humans should be able to identify. Sometimes characters are striked out or presented with a noisy background to make it even harder for computers to figure out the patterns. Most, but not all, CAPTCHAs rely on a visual test. Some Websites implement a totally different CAPTCHA system to tell</span><br style="position: relative; word-wrap: break-word;" /><span style="border: 0px; font-stretch: inherit; font-style: inherit; font-variant: inherit; font-weight: inherit; line-height: inherit; margin: 0px; padding: 0px; position: relative; vertical-align: baseline; word-wrap: break-word;">humans and computers apart. For example, a user is presented with 4 images in which 3 contains picture of animals and</span><br style="position: relative; word-wrap: break-word;" /><span style="border: 0px; font-stretch: inherit; font-style: inherit; font-variant: inherit; font-weight: inherit; line-height: inherit; margin: 0px; padding: 0px; position: relative; vertical-align: baseline; word-wrap: break-word;">one contain a flower. The user is asked to select only those images which contain animals in them. This Turing test can easily be solved by any human, but almost impossible for a computer.</span></span></div> <div style="background-color: white; border: 0px; color: #333333; font-stretch: inherit; font-variant-numeric: inherit; line-height: 20px; margin: 0px 0px 10px; padding: 0px 0px 10px; position: relative; vertical-align: baseline; word-wrap: break-word;"> <b style="color: #783f04; font-family: Times, "Times New Roman", serif; font-style: inherit; font-variant-caps: inherit; font-variant-ligatures: inherit;">Breaking the CAPTCHA system</b></div> <div style="background-color: white; border: 0px; color: #333333; font-stretch: inherit; font-variant-numeric: inherit; line-height: 20px; margin: 0px 0px 10px; padding: 0px 0px 10px; position: relative; vertical-align: baseline; word-wrap: break-word;"> <span style="border: 0px; font-stretch: inherit; font-style: inherit; font-variant: inherit; font-weight: inherit; line-height: inherit; margin: 0px; padding: 0px; position: relative; vertical-align: baseline; word-wrap: break-word;"><span style="font-family: "times" , "times new roman" , serif;">The challenge in breaking the CAPTCHA lies in real hard task of teaching a computer how to process information in a was similar to how humans think. Algorithms with artificial intelligence (AI) will have to be designed in order to make the computer think like humans when it comes to recognizing the patterns in images. However there is no universal algorithm that could pass through and break any CAPTCHA system and hence each CAPTCHA algorithm must have to be tackled individually. It might not work 100 percent of the time, but it can work often enough to be worthwhile to spammers.</span></span></div> </div>
