Liveness testing
This is how systems try to tell the difference between a Gummi bear and your finger or between a photo and a real face.
The list from A to Z
Click on the links below to find out more on each of the entries in the list.
A is for Accuracy
B is for Behavioural biometric
C is for Cash machine
D is for Database
E is for Ear
F is for Facial recognition
G is for Gummi bears
H is for Hand geometry
I is for Iris
J is for Juan Vucetich
K is for Keystroke dynamics
L is for Liveness testing
M is for Mobile phones
N is for Network security
O is for Oxford
P is for Palm
Q is for Queues
R is for Registration
S is for Signature verification
T is for Twins
U is for Universality
V is for Voice verification
W is for Walk
X is for X-ray
Y is for Young
Z is for Zurich Airport
This is especially important with remote transactions - such as making a payment over the internet with a fingerprint or iris scan.
With irises, for example, the red eye effect which often ruins family photos can be used to check whether it is a real iris that is being presented or a photo. Other options include testing for a pulse in a finger or even requiring a user to blink or smile when using a facial recognition system.

It would be interesting to know which of these have published positive and negative failure rates

Iris recognition has actually been around for more than 20 years - a key patent "Flom and Safir" expired in Feb 2006. This has opened to door to commercial competition. Companies like ours are opening up the market with low cost camera devices, and low cost business models for algorithm deployment on devices and on server farms, where large scale cross-matching must take place for ID applications like Cards and Border Control.
