The answer is to use encryption and assume that the data will be decrypted by the people in possession of the keys and once that happens the data cannot be taken away.
If you're trying to give someone a file, and then revoke access later, then you need to have a centralized system with a login. Even then you cannot stop them from copying the file via other means.
