ABSTRACT
Technologies have advanced quickly over the years, making them increasingly diverse every day. Along with this technological advancement, the number of elderly people have grown exponentially in recent years and tend to increase even more. This part of the population is having a greater interest in using these new technologies due to the ease generated. For this reason, they must be accessible to users of all ages. This research aims to evaluate the perception when using the CAPTCHA security mechanism on websites, focusing on elderly users. The main results of the study were the preference for image CAPTCHAs, considering them easier than textual ones. It was found that, in addition to age, factors such as vision problems, education and average daily Internet use influenced the resolution of CAPTCHAs. In addition, the volunteers were observed to feel at ease when resolving this security mechanism.
