A lightweight encryption scheme for visual data based on wavelet filter parametrization is discussed. Being a special variant of header encryption, the technique has an extremely low computational demand. Security assessement of low-dimensional parametrizations schemes show severe weaknesses. We show that using high-dimensional parametrizations the scheme may be employed in applications requiring a medium security level.
