Image Encryption and Iterative Reconstruction of an Encrypted Image

Journal Title: UNKNOWN - Year 2013, Vol 2, Issue 12

Abstract

Encryption is one of the ways to ensure high security for real time applications. In advanced Encryption and data-hiding, Encryption is done only on primary part of image and remaining part is sent as a plain image for secure data communication .A channel provider without the knowledge of a cryptographic key and original content may tend to reduce the data amount due to the limited channel resource. After encoding and on compression of encrypted data into a down sampled sub image and several data sets with a multiple-resolution construction, an encoder quantizes the sub image and the Hadamard-coefficients of each data set are obtained which tend to reduce the data amount. Obtained set of bit streams can be used to reconstruct the detailed content with an iteratively updating procedure and then decryption of data is performed. Because of this iteratively updating coding procedure, the principal original content with higher resolution can be reconstructed when more bit streams are received.
