A new liveness detection scheme for iris based on quality related measures is presented. The novel anti-spoofing technique is tested on a database comprising over 1,600 real and fake (high quality printed images) iris samples proving to have a very high potential as an effective protection scheme against direct attacks. Furthermore, the liveness detection method presented has the added advantage over previously studied techniques of needing just one iris image (the same used for verification) to decide whether it comes from a real or fake eye.
