Prevent bad guys, submite a paper more than one time

my master asks me to prevent a paper to be submitted again.
i searched a lot, but there was no answer . what is unique in one paper?
how can i know a paper was submitted before or not?

Hi @mahsa_idasa,

I’m not sure you you’d automate this – do you have some ideas in mind?

hi @asmecher
Thank you for your answer.
Unfortunately i have no idea too , there is nothing unique for an unsent paper. Even title of a paper cant be unique. :pensive:
