Target assigns every
customer a Guest ID
number, tied to their
credit card, name, or
email address that
becomes a bucket that
stores a history of
everything they’ve
bought and any
demographic information
Target has collected
from them or bought
from other sources.

Kryder’s Law
By 2020, 2.5” drive with 14TB storage will cost $40
Disk Storage has kept pace with Moore’s Law
Moore’s Law
Most people consider it to mean that computing
power will double every two years

It is now cheaper to keep data than to
delete it
Increase in processing power allows us to
analyze stored data in ways not done
before
You can use cloud computing to get
(cheap) access to storage and processing
power

US, UK and other governments are
publishing tax-payer funded data
Intended for use by researchers, application
developers and others
No barrier to corporate use

Immensely useful to sociologists and
anthropologists today and in future
Assuming data format can be understood
Other researchers are finding use for
datasets published by government
Especially about government business transactions
and interactions with citizens

Many companies sell data
Risks are often underplayed (or misunderstood)
Steps are taken to anonymize or pseudonymize
identities with varying levels of success

American Diabetes Association released
figures this year
Direct cost of diabetes in US was $245B in 2012
41% increase in five years from 2007 ($174B)
Roughly 20% of healthcare spending
Indirect cost of diabetes in economy was $68.6B
What if Big Data could cut these costs?

Anonymization and pseudonymization
strategies need to be closely examined
Identification may be possible when datasets are
combined
Consent to release private data should be
obtained first
Problem is that consent is often implied in contract
Preventing colocation of data will not
prevent worst case scenarios

Causation versus correlation!
Developers and managers without research
experience may jump to conclusions
