Abstract
A lightweight JPEG 2000 encryption scheme for mobile environments, based on wavelet filter parametrization, is discussed. Being a special variant of header encryption, the technique has an extremely low computational demand. Compression quality and security assessment show that the scheme may be employed in applications requiring a low to medium security level, provided the conditions for a secure use discussed in this work are obeyed
