Using Benford's Law Divergence and Neural Networks for Classification and Source Identification of Biometric Images

摘要

It is obvious that tampering of raw biometric samples is becoming an important security concern. The Benford's law, which is also called the first digit law has been reported in the forensic literature to be very effective in detecting forged or tampered data. In this paper, the divergence values of Benford's law are used as input features for a Neural Network for the classification and source identification of biometric images. Experimental analysis shows that the classification and identification of the source of the biometric images can achieve good accuracies between the range of 90.02% and 100%.
