Hiding Fingerprint Minutiae in Multiple Facial Images Using BPCS

摘要

Recently, biometric systems have been subjected to various attacks, making their security and integrity imperative. In this research, a robust and immune method was proposed against potential attacks on biometric data. The suggested method is to hide the minutiae of a person's fingerprint in the bit plane of a several randomly selected individual facial images by a particular key using BPCS steganography. The key used to select the host images is encrypted using the RSA algorithm. To compute the performance of the proposed scheme, different experiments were achieved with different biometric databases. The average PSNR of stego images shows low degradation. The PCA as a face recognition approach was adopted. The well known metrics; FAR, FRR, and Accuracy of the system are computed to facial images before and after fingerprint hiding. The results of the implementation of the proposed method proved its efficiency by hiding the fingerprint minutiae in host images in a safe manner. Also, the proposed method proved its ability in increasing the security of both the fingerprint minutiae and facial images.
