An Efficient LSB-Based Steganographic Method for Reversible Image Watermarking with FPGA

Design of an FPGA based reversible watermark extraction system for digital images, with focus on secure and lossless watermarking requirements. LSB manipulation technique ensures that appropriate watermarks can be embedded and extracted without degrading the original image. The approach maintains the quality of the image, which makes it suitable for high-security applications or applications in which data should be preserved. This research shows that the system is capable of providing very fast processing speed, but with minimal requirements that caters to present-day needs of digital design The research work shows that the designed system can support high processing speed and low resources while accurately recovering the original image as well as the added watermark. Such results prove the reliability of the system for use in demanding image regaining protection and securing contents via multimedia in the embedded systems.
