description: The purpose of the study is saving the speed of passing the human-robot check by the user when complicating the generated images by applying adversarial attacks to them. The subject of the work is CAPTCHA services, to which to impede automated recognition use adversarial attacks. The research set the following goals: 1. Studying CAPTCHA generation approaches and circumvention methods. 2. Study of research on the use of adversarial attacks to complicate automatic text recognition on images. 3. Development of a captcha generation method using adversarial attacks. 4. Development of a software package that uses adversarial attacks to protect against automatic recognition on the example of captchas with text. During the work the methods of adversarial attacks and CAPTCHA generation were studied, and current research on their use was analyzed. The work resulted in development of a method of text captcha generation using adversarial attack and a software package that includes a module with this method. The studying point to conclusion that their combined use is applicable. The results could be used as a base to integrate the obtained results into existing solutions on the market.
