How to check if a certain user has visited a certain post/page?

Hello.
I need a confirmation that a certain registered user (role) has visited a post/page which require logging-in and he/she downloaded attachments present in these pages/posts. How can I achieve it? Are there any plugins which give such options?

Thanks for help.
