CAPTCHA

A dystopian world like this needs a reliable way to differentiate an evil bot from a well-intentioned human. How can a banking website be sure that an innocent grandma who is logging in to check that the holiday gift money was successfully transferred to her grandchildren, is in fact, an innocent grandma? Enter, the “Completely Automated Public Turing test to tell Computers and Humans Apart”, or more simply, the CAPTCHA.

В таком антиутопическом мире нужен надежный способ отличить злого бота от человека с благими намерениями. Как может веб-сайт банка быть уверенным, что ни в чем не повинная бабушка, которая входит в систему, чтобы проверить, что деньги на праздничный подарок были успешно переведены ее внукам, на самом деле является невинной бабушкой? Введите «Полностью автоматизированный общедоступный тест Тьюринга, чтобы отличить компьютеры от людей», или, проще говоря, CAPTCHA.

Bunday distopiya olamida sizga yomon botni yaxshi niyatli odamdan ajratib olishning ishonchli usuli kerak. Bayram sovg'asi pullari nevaralariga muvaffaqiyatli o'tkazilganligini tekshirish uchun tizimga kirgan begunoh buvisi aslida begunoh buvi ekanligiga bank veb-saytida qanday amin bo'lish mumkin? "Kompyuterlarni odamlardan farqlash uchun to'liq avtomatlashtirilgan ommaviy turing testi" yoki oddiygina CAPTCHA-ga kiring.

The search engine Alta Vista was one of the first popular websites that introduced a CAPTCHA-like protection when submitting new websites to its database.

There are many other forms of CAPTCHAs, including an audio version for the visually impaired. But it is the curiously simple variety — the “I’m not a robot” checkbox seen on many of today’s websites — that inspired the original question behind this article. This checkbox, endearingly called the “no CAPTCHA reCAPTCHA”, is a Google product that unsurprisingly uses a combination of advanced Google technology to produce a very simple result. Google will analyse your behaviour before, during and after clicking the checkbox to determine whether you appear human. This analysis might include everything from your browsing history (malicious bots don’t necessarily watch a few YouTube videos and check their Gmail before signing up for a bank account), to the way you organically move your mouse on the page. If Google is still unsure of your humanness after clicking the checkbox, you will be shown a visual reCAPTCHA (with words, street signs or images) as an additional security measure. This multi-faceted approach is necessary as computers become more skilled at complex image recognition and with the rise of CAPTCHA sweatshopping (think a large room of underpaid workers tasked with generating a heap of fake social media accounts).
