Client site info

[Danny]

I am a noob in building sites, but hope i can get information about my
answer.

I want to build an security in my site.
Without the user(the one that is alowed to enter) noticing it. So no
password stuf.

I want to do this by letting the site, check something on the client
site computer. Like if a file in a special directory excist or
something.
Only i dont know if something like this is possible. And if yes ,
how??

Hope someone can help me.
Regards Danny
