FPGA Implementation of Digital Watermarking Using Integer Wavelet Transform and AES Techniques

A digital watermarking scheme based on integer wavelet transform and histogram techniques is proposed in this paper. Lifting scheme based integer wavelet transform is used to provide ease of transformation of compressed data and to increase the data embedding capacity. Also histogram technique which is one of the reversible data hiding is used to embed the secret data into original image and retrieve the original data back after extraction. The AES encryption is used to encrypt the embedded image to provide authentication. This algorithm is developed using verilog code and implemented on FPGA Artix 7 board in order to increase throughput, reduce area and power consumption.
