Big Data, Anonymisation and Governance to Personal Data Protection

In a massive processing data era, an emerging impasse has taking scenario: privacy. In this context, personal data receive particular attention, witch its laws and guidelines that ensure better and legal use of data. The General Data Protection Regulation (GDPR) - in the European Union - and the Brazilian General Data Protection Law (LGPD) - in Brazil - lead to anonymisation (and its processes and techniques) as a way to reach secure use of personal data. However, expectations placed on this tool must be reconsidered according to risks and limits of its use, mainly when this technique is applied to Big Data. We discussed whether anonymisation used in conjunction with good data governance practices could provide greater protection for privacy. We conclude that good governance practices can strengthen privacy in anonymous data belonging to a Big Data, and we present a suggestive governance framework aimed at privacy.
