Human Gait Biometrics as Noninvasive Detection Within Business Processes

Qualitative Case Study Analysis of the Transportation Security Administration

Introduction

Introduction

• Future– Something you physically possess

• Fingerprints• Retina• Shape of your face• Ear• Voice

Invasive detection

• Problem– Currently, biometrics are invasive

• Stick your head in a box• Place your finger on a pad

– More materials leading to more repair making current biometrics costly

• Need for biometric stations• Hi capacity areas would have many stations in

need of upkeep• Gummy bear hack

Gait

Noninvasive detection

• Problem solved– Gait is noninvasive

• No pads, no boxes, just move

– No stations• Less to repair

– Only the camera is necessary

– No need to capture a face– No need for high resolution imagery

Literature Review

• “We do not know the extent to which an individual’s gait is unique.”

– Biometric Gait Recognition - J. Boyd and J. Little

• Several factors, other than the individual, that cause variations in gait– Footwear– Terrain– Fatigue– Injury

Qualitative Research

• Analysis of gait as a use of identification vs. fingerprint biometrics– ROC Curves

• receiver operating characteristic• True Positive

– Detecting correctly

• False Positive– Detecting Incorrectly

– Every biometricdetection systemhas one

Qualitative Research

• How secure is biometric data?– Biometrics are not stored like passwords

• If you have the data, then it will do you know good if you don’t know the algorithm used.

• “Biometrics solve the common problem of hacking and mass disclosure of log-in credentials, both of which are highlighted all too frequently in the news.”

» Chris Shepler - co-founder and chief financial officer of Porticus Technology

• Principle of Open Design?

Case Study

• Transportation Security Administration– Average peak waiting time in major airports

is 30 – 45 minutes– What if TSA could identify you as you walk

through the line?• No need for identification• No way to falsify identity• Walk right through metal detectors

– Focus on modifying the current process of TSA security thereby changing the business model

One last thought…

"You have zero privacy anyway. Get over it."
