Biometric Recognition of Identical Twins

The ability to distinguish between identical twins is often thought of as a "stress test" for biometric recognition.  And it is true that the legal system occasionally needs to distinguish between identical twins.  This talk will briefly discuss the biology behind the concept of identical twins, and will  then survey what is known about the ability of the biometrics to distinguish between identical twins.  We will focus primarily on face, fingerprint and iris, but briefly touch on a number of other biometric modalities as well.
