Abstract
Modern age communication prefers digital domain most for data processing and transmission as data augmentation and editing can be performed easily in digital domain. As a result, the purpose of copyright protection for data authentication has become a vital issue. Digital watermarking is an acceptable process with intention to shield copyright. Here a spatial domain watermarking scheme is set up based on adaptive LSB replacement. The hardware execution of the proposed watermark embedding and extracting system is also described using Field Programmable Gate Array (FPGA). The performance of this methodology, evaluated in terms of imperceptibility, robustness and payload capacity, implies the integrity of this watermarking logic. The reliability of this proposed scheme is also confirmed through comparing the proficiency of this process with some existing frameworks.
