Abstract
An anonymization system may include a merger to merge a public database and a private database to create a merged database. The merged database may include multiple blank entries and multiple initial values associated with multiple user identifiers. The anonymization system may include a value generator to fill values for the blank entries via a machine learning algorithm and based on the initial values to create a filled database including the initial values and the fill values. The anonymization system may include a perturber to perturb one or more of the initial values or the fill values of the filled database to create a perturbed database. The anonymization system may include a releaser to release at least a portion of the perturbed database.
