This document discusses both the opportunities and risks associated with big data. It notes that as more devices become connected and collect data, the volume of data being stored is growing exponentially each year.

The document outlines how much personal information is now collected about individuals and sold online, and some of the largest data breaches that have exposed millions of records. It argues that security should be a higher priority to avoid risks from inaccurate data, identity fraud, and loss of privacy as big data continues to expand.
