A general model for the answer-pertubation techniques.

  Answer-perturbation techniques for the protection
of statistical databases were introduced in [7]; they
are flexible (perturbation kept under control),
modular (do not interact with the DBMS)
techniques, which compare fmorably to previous
protection techniques. In this paper, we generalise
the answer-perturbation techniques w. r. t. the
operation used for modifying the exact answers
(thus enhancing the level of protection).
Experimental results are also included; they
indicate statistical soundness of our techniques.
