Access Rights

Hi,

Is it possible to allow a user to read a document but not
able to copy the file content?

Thanks.

Is it possible to allow a user to read a document but not

able to copy the file content?

Not really. Reading is moving a copy to internal memory,
there is little that can prevent writing that back out to a
"new copy".

In theory you could lock down a system so thoroughly that
there is nowhere to WRITE anything, but then that user couldn't
run any program that created temp files or wrote to the disk.

You could run a special application what displays the document
in (with it's own permissions) but has no way to save. This is
not foolproof but can approximate the goal if you are willing to
write a file viewer.

What type of file?
