In accordance with the signed license agreement, the use of the
iThenticate system is permitted to only those with a Ph.D. or a higher degree. Furthermore, student assignments, projects, and theses as well as articles sent to the editorship of any journal, whether it is commercial or not, should not be checked through the system. In other words, if any of the authorized users at your university (with a Ph.D. or higher degree) is the editor of a journal published by your university or another institution, and if an article is sent by an author to be published in that journal, the editor of that journal cannot check that article in the iThenticate system. However, if the author who submits the article is an authorized user of a university (even at the same university as the journal editor), he/she can check the article and receive a report through his/her iThenticate account before submitting it to the editorship of the journal in question. The restriction is valid only for journal editors. Checking personal work is not an issue.
