As planned for two years, Google et Apple Inc. have officially announced their intention to stop using Captcha for all their users by the end of the year, according to Cybersecurity Insiders.
Captchas (English acronym Completely Automated Public Turing test to tell Computers and Humans Apart) are a combination of alphanumeric characters used by servers to differentiate between humans and bots online. These Captchas typically ask users to solve puzzles by selecting the correct images from a series of boxes arranged in different shapes. With rapid advances in artificial intelligence, Recent security studies have shown that bots have become very sophisticated and can now solve Captchas in as little as 20 seconds, which compromises the effectiveness of Captcha technology. Hence the new equation to solve for Jake Moore, Global Security Advisor chez ESET : “AI has become more efficient quickly enough to make Captcha tests superfluous, but with the evolution of technology we are faced with another dilemma : how to improve everyone's online experience while keeping bots under control ? »
The game of cat and mouse
“While this may seem like a victory for the online experience, Protective Captchas have helped make websites more secure and largely bot-free, so other solutions are desperately needed. Two-factor authentication improves security and can also provide quick access to websites, but it usually involves a login process which is not always suitable for those who wish to remain anonymous and users concerned about their privacy. Unfortunately, AI plays a natural role in this constant game of cat and mouse and, therefore, every time a new method is announced, technology quickly tries to circumvent it, which causes difficulties for those trying to protect their users. »
