Improving Efficiency in Image Encryption Then Compression System
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 3
Abstract
As the use of digital techniques for transferring and storing images are increasing, it leads to an major issue that how to protect the security of images and also to reduce the size of the images to avoid the traffic in the network. There are various techniques which are discovered from time to time to encrypt the images in order to make the images more secure. In present times, the protection of multimedia data is becoming very important. The protection improving the efficiency of this multimedia data can be done with encryption and compression. There are many different techniques used to protect confidential image data from unauthorized access and to compress the image. The classical way of transmitting image over a bandwidth constrained insecure channel is to first compress it and then encrypt. This report investigates the novelty of reversing the order of compression and encryption, without compromising either the encryption efficiency or the information secrecy. Image encryption has to be conducted prior to image compression in any transmission medium to ensure secure and compact transfer of images in a network. The proposed system is to design a pair of image encryption and compression such that compressing encrypted images can still be efficiently performed. A highly efficient image Encryption-ThenCompression (ETC) system is designed. In ETC System the image is encrypted and then compressed before transmission and then after performing it, the image becomes secured and reduced in size. The encryption scheme used is the Discrete Wavelet Transform (DWT) which increases the security level and prevents the attack of the encrypted image. The compression technique used is 2D Haar Wavelet Transform for increasing the efficiency and to attain high compression ratio.
