Abstract :
We present improvements in lightweight transparent JPEG 2000 encryption with lifting parameterized biorthogonal wavelet filters. Security is further enhanced by a combination with the wavelet packet transform. Different methods for the selection of a suitable wavelet packet basis are presented, which also make a certain amount of control in the trade-off between security and computational complexity possible. The combined approach of parameterized filters and wavelet packets is evaluated with regard to compression performance, complexity and security
