Fingerprint liveness detection using convolutional neural network and fingerprint image enhancement

Use of a biometric authentication system is growing recently. Because of that, spoof fingerprint detection has also become important. There are several algorithms used in the fingerprint liveness detection. Some of them are software based and some others are hardware based. With the fast growth in software technologies, now we mostly concentrate on software based methods. Here a software based technology; Convolutional Neural Network is implemented. Along with this a fingerprint image enhancement technique is also used in order to provide clear image for classification after the convolution.
