Abstract
A method for detecting a fake finger for fingerprint acquisition software with improved performance, the method implementing a static analysis step including a calculation of a Gray Level Run Length matrix of an image of a finger. Optionally, but preferably, the static analysis and a dynamic analysis are combined so as to optimize the ability to detect fake fingers.
