Encryption of wavelet-coded imagery using random permutations

In this paper we investigate the impact of using random coefficient permutation to provide confidentiality in wavelet-based still image compression pipelines. We compare the changes in compression performance of JPEG 2000 and SPIHT-based schemes and discuss key management scenarios. The results also...

Zusammenfassung:	In this paper we investigate the impact of using random coefficient permutation to provide confidentiality in wavelet-based still image compression pipelines. We compare the changes in compression performance of JPEG 2000 and SPIHT-based schemes and discuss key management scenarios. The results also have interesting implications with respect to the significance of the zerotree hypothesis.
