I was asking for similar feature in the past as well. If your problem is the same like mine, you'd be using copy-on-read feature which would copy-up all files where atime is updated.
I think you simply need a log of files which are open/read. This kernel module will do the job for you: ftp://ftp.slax.org/source/slax/kernel/2.6.20/src-core/probe.tar.bz2 Make sure to enable kprobes in your kernel configuration. After the module is loaded, you'll find a log of all opened/read files in syslog. This module has been written by Junjiro Okajima for me personally, I hope he won't mind I'm sharing it.
