4. Information Privacy
Data privacy is the
relationship between
collection and dissemination
of data, the expectation of
confidentiality, and
associated legal issues
5. Encryption
• One of the core information
security tools used to ensure
information privacy
• As you watch the video, think
about how the power of
encryption can be both
beneficial as well as
detrimental, depending on the
situation
6. Think of These Things
Are They Protected Well
Enough?
• Healthcare records
• Criminal justice investigations and
proceedings
• Financial institutions and
transactions
• Biological traits, such as genetic
material
• Residence and geographic records
• Ethnicity
7. Encryption -- Privacy Enhancing
Technology
• Any technology which
increases control over
personal data (PET)
• Why do people have an
aversion to using PETs?
8. Costs
• Additional hardware,
additional software licenses
• Personnel costs for designing,
developing, implementing,
testing and deploying the
privacy enhanced service,
operating and maintaining the
privacy enhanced service
• Costs for training customer
support
9. Time Spent and Vulnerability
• Fixing additional system failures or
problems due to increased system
complexity (more functionality
means higher complexity which
leads to higher vulnerability)
• Product management of the
additional privacy enhancing
functions (more functions require
more time spent to manage them)
10. Benefits of PETs
• Increased usage of online
services by existing customers
and increased number of new
customers due to higher trust
in the service
• Stronger public image for your
company
• Competitive advantage
11. Things to Think About
• Based on what you learn from the
video, how important do you think
PETs will be to individuals,
businesses, the government and
criminals in the near future?
• As the new CIO of a major
corporation, how would you
address information privacy in light
of the changes in government
policy since 9/11?
