As digital video flows freely across platforms and borders, the question of who made what has grown harder to answer with each compression and re-upload. Researchers have proposed a framework that weaves cryptographic proof of ownership directly into the fabric of video itself — invisible to the eye, resilient to manipulation, and mathematically traceable back to its creator. By marrying transform-domain mathematics, neural networks, and chaotic encryption, the work does not dissolve the ancient tension between invisibility, durability, and security, but it shifts the balance further than prev
