A novel encryption scheme for securing biometric templates based on 2D discrete wavelet transform and 3D Lorenz-chaotic system
This research paper proposes a novel encryption and decryption scheme for biometric templates using two dimensional discrete wavelet transform (2D-DWT) and three dimensional (3D) Lorenz-chaotic system. In the proposed scheme two levels of 2D-DWT are used for the decomposition of the group representa...
