Abstract

Answer-perturbation techniques for the protection of statistical databases have been previously introduced (Luchian and Stamate, 1992); they are flexible (perturbation kept under control), modular (do not interact with the DBMS) techniques, which compare favorably 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
