What is BIOINFORMATICS?

• Have you ever thought that a cure for cancers
  could be developed by people working at their
  computers?

What is BIOINFORMATICS?

• Have you ever thought that a cure for cancers

• Modern high-throughput technologies are
  generating tremendous volume of data - somebody
  needs to store and manipulate the data, generate
  reports and share them with the scientific
  community.

Biotechnology and pharmaceutical industry

• Biotechnology and pharmaceutical industry
  revenues are estimated at hundreds of billions of
  dollars annually.
• The industry's claim is that they spend 800
  million on research development for every new
  drug which receives FDA approval.
• Much of the RD efforts are pursued
  computationally these days.

Some of our Security Work

• Mobile Device Protection against Loss and Capture
  (PETRA09)
• Our forward secure two-party signature scheme
  provides stronger device authentication to make
  it work against impersonation
• Privacy-Enhanced Opportunistic Networks (PSPAE09)
• group mobile nodes together to randomly detour
  the traffic to protect from timing traffic
  analysis (which leads to privacy leakage)
• Providing Location Privacy (PETRA08)
• use dynamic zone to mix some location records of
  some moving objects to protect against tracking
• Source Location Privacy (SecureCom08)
• hide event messages into maintenance messages so
  that an attacker can not track where an event is
  happening (if source location information
  is sensitive)
• Preventing Unofficial Information Propagation
  (ICICS07)
• use short-lived certificates with forward secure
  signatures to make the information on a
  certificate not verifiable shortly after usage
• Challenges
• how to apply expensive (resource consuming)
  cryptosystems in mobile, portable, assistive
  devices (computationally limited)
• faster encryption methods that a light mobile
  device can afford.
• anti-data-mining mechanisms and privacy
  preserving technologies to address the increasing
  public concerns on privacy information leakage.

Behavioral Markers Making Genotype-Phenotype
Correlations

• Certain genetic anomalies lead to certain
  diseases/disabilities (phenotype is any
  demonstration of the conditions, such as a scan).
• Understanding Genotype-Phenotype correlations may
  help create more effective treatments.
• Challenges
• How to correlate certain medical conditions with
• observable behaviors or physiological
  conditions.
• How to use correlations to enhance decision
  making.
• How to analyze the effects of medical
• treatments and adapt to patient
• condition.

Active Service Robots
Problem When abnormal event occurs, how can a
robot decide what to do?

• Approach
• robot investigates and prompts human to respond
  by keyboard, touch screen, or voice.
• Human cancels/confirms alarm or no action.
• Then robot makes a decision based on the
  available streams of sensor and human information
  using partial order Markov decision processes.
• Challenges
• Setting up the hierarchy of decision making to
  determine what level of action is appropriate by
  funneling the events of four different data
  streams into the partial order Markov decision
  process.
• Able to access additional sensors to confirm
  the status of the human
• Evaluating and testing the correctness of the
  decisions.
