hi , i want to protect for my word file and here is example about what i want :
i want to make word file and do these things with it

1- set user and password for file , also if i can change it online it will be better, like network with user and pass and nobody can login to the lessons if he doesn,t know the password.

2-the person who use my file cant move or share it with anybody or extract it etc..

3- i want to set timer ,so all information and every thing in word file! disappear after 1 week
from opening.

because i want to make lessons for students, and I don,'t want them to share it or give it to anybody
thank you
