Data Security and Privacy


Security deals with the assurance of a set of
rules set to protect privacy

Prevent access to the environment

Prevent unauthorized access to data
Privacy deals with the subjective, culturedependent setting of standards that regulate
what is publicly accessible

Determine who should have access to what

Where are the limits for public access ?
Privacy in Intelligent
Environments

Privacy in intelligent environments
encompasses many aspects

Which data should be private ?

Who should have access ?

What means of information gathering can be used ?
Types of Privacy

Bodily Privacy


Territorial Privacy


Privacy Of Your Home, Office, …
Privacy Of Communications


Strip Searches, Drug Testing, …
Phone Calls, E-mail, …
Informational Privacy

Personal Data (Name, Address, Hobbies, …)

Security and Privacy-Aware
Environments

Security measures for access authentication
are not sufficient in intelligent environments

Access to information inside the environment has
to be limited


Home interfaces and displays have to follow
privacy rules


Multiple inhabitants should have access to different parts
of the available information
Interfaces can not display private information
Access inside the environment might have to be
restricted


Private spaces in office environments
Access restrictions to ensure safety of inhabitants
Remote Interface Example:
Georgia Tech Aware Home

Actual Environment:



Pressure sensitive floors
Microphone arrays
Video cameras
Remote Interface Example:
Georgia Tech Aware Home

Family Portraits:

Summarize daily activity
and long-term trends
iconically


Limits access to information
Provides peace of mind for
adult children
Privacy in Intelligent Interfaces

Interface should only display the required
information

Hide sensory data


Only display result of processing


E.g. no video data, no exact data on current actions
E.g. only display if everything is ok
Interface structure should reflect the
necessary information

Interfaces have to be practical and easy to use
without revealing information

E.g. only display static, pre-recorded image of person
