Um estudo comparativo de mecanismos de privacidade diferencial aplicado à resolução de entidades com garantias de privacidade.

Abstract

The progress of technology has generated an evolution in the popularity of services that use data exchange, allowing unknown or unreliable computers to keep a large amount of information about individuals based on their data provided. As a result, maintaining user privacy while ensuring service quality is a complex dilemma that has received attention in recent years. The integration of these various databases can occur through Entity Resolution (ER), however in many situations these data are private, something not supported by RE. Then comes the Privacy Entity Resolution (REGP) with the same purpose as the RE, but with the addition of data privacy support. One of the data protection techniques used in REGP is known as Differential Privacy (PD) which consists of using mechanisms to add noise to records. This work proposes to evaluate data privacy through PD mechanisms applied to REGP.
