Big Data concerns

• Big Data gives us unprecedented insights and
  opportunities, but it also raises concerns and
  questions that must be addressed
• Data privacy The Big Data we now generate
  contains a lot of information about our personal
  lives, much of which we have a right to keep
  private
• Data security Even if we decide we are happy for
  someone to have our data for a particular
  purpose, can we trust them to keep it safe?

Big Data concerns

• Data discrimination When everything is known,
  will it become acceptable to discriminate against
  people based on data we have on their lives? We
  already use credit scoring to decide who can
  borrow money, and insurance is heavily
  data-driven. We can expect to be analyzed and
  assessed in greater detail, and care must be
  taken that this isnt done in a way that
  contributes to making life more difficult for
  those who already have fewer resources and access
  to information.

  Hadoop give you the scale and flexibility to
