It is possible for Singular Value Decomposition (SVD) watermark embedding to have a quasi-one-way functionality. While basic SVD embedding has the drawback of being non-reversible, an advanced SVD method which uses a reversible relation only works one-way. When embedding takes place, the decomposing matrix obtained from the original image differs from the one obtained from the embedded image. This paper demonstrates that there is a distinct difference which shows discontinuity in the Euclidean Norm when evaluated numerically. This evidence points towards the probability that SVD embedding is resilient to inversion attacks.
