Answer to Question 1

3
Rationale: This statement about KDD is accurate: The confidentiality of individual records may be protected through the use of data perturbation. This is a technique that modifies actual data values to hide confidential information while maintaining underlying aggregate relationships of the database. Further research is needed on the use of data perturbation and its potential to introduce bias (lack of bias is not guaranteed by the vendor). Commercial packages are available in a range of prices and platforms. KDD provides a powerful tool suitable for the analysis of large amounts of data, but not small amounts.
