Digital Watermark Embedding and Extraction Techniques

Abstract
In the modern digital era, data piracy is a major Concern for the content available across the internet, making it need perfect space in this sentence it very difficult to shield it from various piracy attacks. An effective digital video watermarking technique that is robust, invisible to the human eye, and also computationally efficient is Essential. The digital media watermark embedding and extraction techniques are divided into spatial domain and frequency domain based on the domain in which the watermark is embedded, each offering distinct trade-offs between robustness, impercepti- bility, and computational complexity. By carefully selecting the key frames and embedding regions, watermarking systems can achieve a balance between visibility, data capacity, and resilience to common attacks like compression, cropping, and noise.This paper presents a review of different watermarking approaches focusing on different key frame selection strategies and various area selection techniques for robust watermark embedding.
