The following paper presents a comprehensive conceptual framework addressing security issues in watermarking. The widespread availability and usage of digital data, such as videos, audios, and images, due to the expansion of the internet, have introduced security challenges. To establish authenticity in multimedia data, techniques like encryption, steganography, and watermarking are employed. Extensive analysis of several high-quality research papers reveals the existence of numerous methods that can successfully implement digital watermarking, tailored to specific application requirements. These methods include DWT-DFT-SVD, LWT-WHT-SVD, DWT-QR, and DWT-FFT-SVD. In our research work, we will proceed in three distinct phases. First, we will prepare a dataset upon which the chosen watermarking technique will be applied. Second, we will evaluate different watermarking techniques to identify the one that yields optimal results in terms of PSNR (Peak Signal-to-Noise Ratio) and processing time. In this phase, we will subject the images to various attacks to ensure the implemented method can withstand such adversarial attempts. Finally, in the third and final phase, we will execute the reverse process to extract the host image and watermark. By following this structured approach, we aim to contribute to the field of security in watermarking and provide insights into efficient and robust techniques for protecting digital content integrity.
