Designing an Efficient Image Encryption-Then-Compression System with Haar, Daubechies and Symlet Wavelet

Ambika, Neha

Abstract: Images can be encrypted with different ideas which is a modified International DAUBECHIES, SYMLET and HAAR Wavelet with Data Encryption Algorithm to encrypt the full image in an efficient secure way, after encryption the original file will be compressed and get compressed image. The ideas of image encryption scheme operated in the prediction error domain are shown to be able to provide a reasonably high level of security. Here also find that an arithmetic coding-depend approach can be exploited to efficiently compress the encrypted image. In contrast, the existing ETC solutions induce significant penalty on the compression efficiency. Haar, SYMLET and DAUBECHIES wavelet transform using with ETC perform better compression efficiency.
