Abstract
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for using additive and subtractive noise for preserving the privacy of users. In one aspect, a method includes obtaining a first set of genuine user group identifiers that identify user groups that include a user as a member. A second set of user group identifiers is generated for the user by removing zero or more genuine user group identifiers from the first set to generate the second set and adding, to the second set, one or more fake user group identifiers for user groups that do not include the user as a member. A probabilistic data structure is generated based on the second set of user group identifiers. The probabilistic data structure is transmitted. Data indicating a set of digital components including at least one digital component selected based on the probabilistic data structure is received.
