I have seen some sites that have online tests with tracking, capturing which screens the user has opened on the computer, be it browser tab or other software, this question can be closed because it is in the opinion of some ' wide, 'but to my point of view it is not, it's just a start for that path, where I've seen a lot of developers curious to learn.
My biggest question is how to search for content related to the subject, are there specific terms? If any member of the community is willing to give a broader answer, saying tools that can be used for this, I and other people would be grateful.
PS: Remembering that it is a website . What is the way to do this type of verification? In short, capture tabs or open softwares.
