It is a reality, we live in the world of Big Data. The use of Big Data creates new issues in different ways as the volume, velocity, and variety of the data that processes. However, many other problems are related to how to secure the data privacy and the data itself. In this chapter, we will describe a full perspective of the problematic. Furthermore, we will explain the main international proposals that address the security and privacy in Big Data environments.
