Exploiting multiple orthogonal transformations for hybrid attack resilient video watermarking

This academic paper describes a method for protecting videos using watermarking (a technique that embeds hidden information into media to prove ownership or detect tampering) by applying multiple mathematical transformations to make the watermark resistant to attacks. The research, published in November 2026, proposes using orthogonal transformations (mathematical operations that preserve certain properties) in combination to create a hybrid approach that is harder for attackers to remove or corrupt.
