What's the point of homomorphic encryption if you can still see how the behaviour changes? You might as well just make the desired behaviour public and don't bother with trying to somehow get something to read sensitive data and change its behaviours accordingly without leaking information about the data (which is not feasible, no matter how advanced your encryption).
