A Combined Image Compression and Encryption Scheme

Abstract:

In the paper, a novel combined image encryption and compression scheme is proposed. It performs encryption before compression. Making use of the properties of discrete wavelet transform (DWT) and Set Partitioning in Hierarchical Trees (SPIHT) coding, confusion is restricted to the interior of single subband image itself and so image details are retained. The proposed algorithm possesses a good visual quality of the reconstructed image and a high encryption speed.
