Abstract Biometric scan images are used for authentication purposes widely. Because they are unique in nature, the use of biometric scan images is increasing day-by-day in authentication and security. Due to the economic-based systems such as banking and financial sectors are using biometric-based security and authentication, the use of biometric images is increasing every day. In this paper, the fingerprint of the user is taken as key image for DES algorithm and it is used for the encryption of fused image. Hardware implementation of data encryption standards algorithm is designed. For enhancing the target information content in image, using MATLAB software, two multi-focus images are fused. The dual-tree-complex wavelet transform is used for the fusion of images. The comparison is done with other hardware designs in terms of number of LUTs and power and complexity of implementation with other encryption techniques. This paper gives the secure transmission of fused images using DES encryption, with the use of biometric image as a key image, which is strong and unique method for security and authentication in nowadays.

1 Introduction Biometric scan images such as fingerprint, face, iris, thumb, and hand impression are used for authentication and security purposes widely. Because they are distinctive in nature, its use is increasing day-by-day in authentication and security. Due to the G. Gaur (B) · J. B. Sharma · L.

economic-based systems such as banking and financial sectors are using biometricbased security and authentication of the use of biometric images is increasing every day. We use dual-tree complex wavelet transform (DT-CWT) here to fuse two multifocus images. There are various fusion techniques available today, and their utilization based on requirement is chosen by user. Here in this paper, DT-CWT is used because of its quality as compared to other fusion techniques like averaging method, Pyramid method, curvelet, DWT, and SWT. After the DT-CWT-based fusion operation, DES encryption is applied to this fused image, using the biometric scan image of user such as fingerprint as a key image. Recovery of securely transmitted image is possible by using the same authorized key image [1, 2]. Otherwise, the original fused image is not obtained and this is the main aim of this work done in this paper. Verilog implementation of DES using Xilinx ISE t
