Couldn't you override call_other in the AUTO to call this security function
of yours and get the same result?  Granted, you'd need to write that
validate function in each object, and you'd be imposing a small cost on all
call_others (the large majority of which likely won't be giving rise to
security concerns), but this would meet your requirements, wouldn't it?
