Verilog Implementation of Biometric-Based Transmission of Fused Images Using Data Encryption Standards Algorithm

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.
