How can you prove the use of programs / sites / services to increase the exclusivity of the text?

Question

Text analysis

Some students use specialized sites where you can increase the exclusivity of the text of your thesis. On these sites, you can also choose which service / resource will be checked for anti-plagiarism. After uploading the work to such a specialized resource and choosing a site where the work will be checked, the output is a work (with the same structure of sentences, etc.) a complete copy of the downloaded one, but when checking for anti-plagiarism, the system already gives out a high exclusivity of the text.
From here I have a question: How can I prove the use of programs / sites / services to increase the exclusivity of the text?

Answer 1

The search for hidden characters in the text of the work must be carried out, all unique services are built on various variations of their application.
