AI-Based Algorithm Developed by Researchers Could Make Text Captchas Obsolete

British and Chinese researchers from UK's Lancaster University and China's Northwest University and Peking University have developed a new artificial intelligence-based attack against text captchas which could make them obsolete.

"The new algorithm, based on deep learning methods, is the most effective solver of captcha security and authentication systems to date and is able to defeat versions of text captcha schemes used to defend the majority of the world’s most popular websites," states the research team. 

According to the research team behind the "Yet Another Text Captcha Solver: A Generative Adversarial Network Based Approach" paper, their new captcha solver does not need high volumes of real captchas as a training ground since it is not based on a machine-learning approach.

"This is achieved by first learning a captcha synthesizer to automatically generate ...
