Big Data: Legal Challenges (Full Report)
The quantity of information available in the world has
dramatically increased in the last 10 years.
Today the quantity of information in the world doubles every
three years1. In the year 2000 it was estimated that
only 25% of the world's information was in digital form (stored
on computers or computer storage media), the rest being analogue
information (records, tapes, books and printed matter). By 2007 the
picture had changed dramatically with only seven percent of the
world's information in analogue form and 93 percent
digital.
Martin Hilbert of the University of Southern California
calculated that there was 300 exabytes (an exabyte is one billion
gigabytes) of data in existence in 2007. An IDC study predicts the
growth of information by 2020 to be to 40,000 exabytes.
