Abstract:
The biggest challenge for big data from a security point of view is the protection of user’s privacy. Big data
frequently contains huge amounts of personal identifiable information and therefore privacy of users is a huge concern.
Because of the big amount of data stored, breaches affecting big data can have more devastating consequences than the data
breaches we normally see in the press. This is because a big data security breach will potentially affect a much larger number
of people, with consequences not only from a reputational point of view, but with enormous legal repercussions. While using
big data a significant challenge is how to establish ownership of information. If the data is stored in the cloud a trust boundary
should be establish between the data owners and the data storage owners.
