Efficient Grayscale Image Encryption Then Compression System

In secret communication, images are widely used and the major issues are how to protect the image and also reduce size of the image in order to maximize the network utilization. Various techniques are there in order to secure the image and to reduce the size of the image. In many practical scenarios, encryption of an image has to be conducted before the image compression. In proposed scheme, bo...

Lattice algorithms for compression color space estimation in JPEG images

JPEG (Joint Photographic Experts Group) is an international standard to compress and store digital color images [5]. Given a color image that was previously JPEG-compressed in some hidden color space, we aim to estimate this unknown compression color space from the image. This knowledge is potentially useful for color image enhancement and JPEG re-compression. JPEG operates on the discrete cosi...

Designing an Efficient Image Encryption-then Compression System

In many practical scenarios, image encryption has to be conducted prior to image compression. This has led to the problem of how to design a pair of image encryption and compression algorithms such that compressing the encrypted images can still be efficiently performed. In this paper, we design a highly efficient image encryption-thencompression (ETC) system, where both lossless and lossy comp...

Efficient selective encryption for JPEG 2000 images using private initial table

In this paper, we propose an efficient selective encryption scheme for encrypting JPEG 2000 images. The proposed scheme uses a secret key and a mapping function to generate a private initial table to encrypt the selected DWT codeblocks in the entropy coding stage of JPEG 2000 coding scheme. Theoretical analysis and experimental results show that the proposed scheme can achieve various purposes ...

Encryption-then-Compression System using Haar and Symlet Wavelet Transform

Image compression is the important task for the medical images. Economic and effective image compression techniques are hardly required to minimize the storage volume of medical database in hospitals as well as maintaining the image quality. But the transmission and storage of such a large data could be a tedious job. There are various methods to encrypt the images while transmission. In this r...
