New Experiments with Optical Liveness Testing Methods

This article describes experimental results, which have been achieved from our three realized solutions of liveness detection. These liveness detection solutions were patented (international patent WO/2007/036370, Czech utility model UPV19364) and
theoretically introduced in the previous work. First solution is based on detection of changes of distance between neighbor papillary lines caused by pulse, second is based on detection of volumetric changes by the use of laser distance sensor and third on causation of optical changes. This article is oriented on the description of obtained results from realized experiments. There has also been developed a special optical bench for the measurement of our methods.
