An Effective Approach Of Compressing Encrypted Images
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2013, Vol 2, Issue 10
Abstract
In this paper proposing a novel scheme of scalable coding for encrypted images. In the encryption phase, the original pixel values are masked by a modulo- 256 addition with nonrandom numbers that are derived from a secret key. After decomposing the encrypted data into a down sampled subimage and several data sets with a multiple-resolution construction, an encoder calculates the subimage and the Hadamard coefficients of each data set to reduce the data amount. Then, the data calculates subimage and coefficients are regarded as a set of bitstreams. Because of the hierarchical coding mechanism, the principal original content with higher resolution can be reconstructed when more bitstreams are received.
