MOTIVATION
Currently, iris and fingerprint recognition systems can be found worldwide with outstanding rates of success.
Whilst recognition methods evolve, new ways of spoofing them break out as well, creating a need for safer solutions in order to guarantee the authenticity of the collected images.
Prior to the recognition process, especially in a scenario where no human control is required, the system should be able to recognize whether a biometric trait is real or if someone is trying to access the system fraudulently. One way of achieving that is by assessing the liveness of the sample.
Since both iris and fingerprints are rich in texture, the same methods of detecting the liveness of the traits could be, theoretically, applied to them. The challenge now is to test if a method perform the same way with different traits or if the characteristics of iris and fingerprints influence the accuracy of a liveness detection method.
