It sounds like you want something like like incrond, which gives you
user-space hooks into the inotify kernel subsystem.  I have used it, for
instance, for protecting artifacts published to a develpment archive
server.  I use incron to monitor the directories where artifacts can be
uploaded, and as soon as an upload is completed, then incron invokes a
call to 'chattr +i' to make the new file immutable and thus protect it
from being overwritten by a subsequent upload or deletion.

Because it can also simply log accesses, reads, etc., it will probably
do exactly what you want.
