Abstract
A method (100, 400) for managing access to a database is disclosed. The method comprises receiving a database query, (110), executing the query on the database to obtain a result, (120), generating a noise value, (130), perturbing the result with the generated noise value, (140), and outputting the perturbed result, (150). The noise value is generated from a bimodal probability distribution having a minimum probability at zero noise. Also disclosed is an access management processing element, (200, 300, 600) for a database.
