Abstract

This paper presents a verification test on a quasi-one-way characteristic of SD watermarking. Norm of distance between tow matrices is one of measures for evaluating degree of computational burden against reverse analysis.The norm distance shows a kind of nonlinearity and even non-continous phenominon, in spite of the norm is smooth quadratic function.
