The "I'm not a robot" on the Internet may soon become a thing of the past. Google officially announced its service Invisible reCAPTCHA (invisible rekapcha) that can distinguish humans from bots without any additional action by users of the site. This improvement places Kupchan (CAPTCHA) and rekapchata (reCAPTCHA) in the past, as the new service provides greater ease of use by real users. According to Google, the new technology uses machine learning and improved system of risk analysis. The user must enter characters only if the system actions are suspicious.
Kupchan and rekapchite are important to web developers as they help to prevent attacks by malicious bots on websites. Without this form of security sites are under attack and suffer from spam and other forms of exploitation.
