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...

description 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 representation of the different biometric templates and then substitution and permutation are applied using some mechanism and 3D Lorentz-chaotic system. The encryption scheme is applied on the different sub-bands of each level of decomposition, and for the decryption, the reverse process of the encryption is used. The experimental results, biometric template matching, security analysis, and statistical analysis of the proposed scheme are given to validate the robustness of the scheme. The security analysis shows that the brute-force attack is not possible in the proposed scheme.
