A new perceptual encryption scheme with an efficient key-management mechanism for the Motion JPEG 2000 based ETC system is proposed in this paper. An ETC system is known as a system that makes image/video communication secure and efficient by using perceptual encryption and image/video compression. Unlike conventional ETC systems, the perceptually encrypted images by the proposed scheme can be efficiently compressed by the Motion JPEG 2000. Moreover, an efficient mechanism to manage a lot of secret keys for video sequences is provided to avoid complex key-management. The experimental results demonstrated that the proposed scheme achieved both acceptable compression performance and enough security for secure image/video communication while remaining compatible with the Motion JPEG 2000 standard.

In ancient times, there was a need to protect data. Due to the pervasive range in the field of security, several technologies came into existence. But the whole idea of securing data from attacks took a quick turn in the world of Internet. Here, data accuracy is the major issue. As in the previous existing methods, compression of data becomes an important research field that provides an efficient way for compressed data transmission over the Internet. The technique proposed here publicizes the concept of reliability and transmission mechanism. This is a faster and simple method of compression, and describes different lossless image compression algorithms for high performance. The newly adapted method produces better image quality without any loss of data. The suggested approach highlights security of data and provides a practical approach for compression of an image. The proposed ACE scheme works on binary concepts of compression of the image and encryption by reducing number of bits per pixel.

We propose a novel content based-image retrieval scheme for encryption-then-compression (EtC) images. In conventional retrieval schemes for EtC images, the JPEG standard was applied to EtC images as a compression method, although EtC images can be applied to both JPEG compression and lossless compression methods such as JPEG-LS. In contrast, the proposed retrieval scheme allows the mixed-use of lossless and lossy-compression methods. In an experiment, the proposed method is demonstrated to maintain a high retrieval performance, even under the mixed-use of lossless- and lossy-compressed EtC images.

This paper proposes a crypto-compression scheme to protect the distribution and storage of digital medical images. The proposed process uses a chaotic system in order to provide an efficient digital medical images encryption. This enhanced scheme combines between compression based on DCT and encryption. Simulation experiment, sensitivity and statistical analyses have validated the effectiveness of the proposed system.

Data encryption is one of the key information security technologies used for safeguarding multimedia content from unauthorised access and manipulation in end-to-end delivery and access chains. This technology, combined with the appropriate cryptographic methods, effectively prevents the content against malicious attacks, so as to protect its authenticity as well as integrity. While encryption-based security is ensuring the authorised consumption of the multimedia content, content adaptation technologies have the primary goal of providing means for wider dissemination of the content across diverse networks, devices and users, and thus enriching user satisfaction and experience of the delivered content within a given set of usage environment constraints. Traditionally, protected contents can only be adapted at trusted adaptation engines residing between the source and end-users, since they have to be fully decrypted before performing the necessary adaptation operations. The drawback of such a process is that it significantly limits the availability and flexibility of adaptation engines applicable for adapting protected contents on the fly. Thus, this paper proposes a novel scalable H.264/advanced video coding (AVC)-compatible video encryption technique, which is also transparent to adaptation engines in an end-to-end video delivery scenario. The proposed technology relies on keeping syntax elements required for performing the adaptation operations clear (i.e., not encrypted). The effectiveness of the proposed technique has been successfully verified in scenarios, where both conventional joint scalable video model (JSVM) bit stream extracting and random packet dropping mechanisms are used.

Data compression is an important part of information security because compressed data is more secure and easy to handle. Effective data compression technology creates efficient, secure, and easy-to-connect data. There are two types of compression algorithm techniques, lossy and lossless. These technologies can be used in any data format such as text, audio, video, or image file. The main objective of this study was to reduce the physical space on the various storage media and reduce the time of sending data over the Internet with a complete guarantee of encrypting this data and hiding it from intruders. Two techniques are implemented, with data loss (Lossy) and without data loss (Lossless). In the proposed paper a hybrid data compression algorithm increases the input data to be encrypted by RSA (Rivest-Shamir-Adleman) cryptography method to enhance the security level and it can be used in executing lossy and lossless compacting Steganography methods. This technique can be used to decrease the amount of every transmitted data aiding fast transmission while using slow internet or take a small space on different storage media. The plain text is compressed by the Huffman coding algorithm, and also the cover image is compressed by Discrete wavelet transform DWT based that compacts the cover image through lossy compression in order to reduce the cover image's dimensions. The least significant bit LSB will then be used to implant the encrypted data in the compacted cover image. We evaluated that system on criteria such as percentage Savings percentage, compression Time, compression Ratio, Bits per pixel, Mean Squared Error, Peak Signal to Noise Ratio, Structural Similarity Index, and compression Speed. This system shows a high-level performance and system methodology compared to other systems that use the same methodology.

In this paper, a new algorithm combined compression and image encryption is presented. The proposed algorithm can be used in the field of high-speed confidential data transmission where security is required. The compression is based on a hierarchical structure called SPIHT(Set Partitioning in Hierarchical Trees). This compression is followed by an encryption scheme PSCS (Parametric Switching Chaotic System). The performances of this technique were evaluated in terms of compression quality and data security. Simulation results have shown the effectiveness of this technique, and thereafter, it is ready for a hardware implementation.

Digital watermarking has been recently proposed as the mean for property right protection of digital products, In this paper we analyze the self-similarities of wavelet transform and present a new approach to embed a digital signature into an image based on self-similarities in detail signals of discrete wavelet transform of the image for the purpose of protecting the copyright of the image. The signature embedded using this method is retrievable only by the mean of protected information. Our studies have shown that the watermarked image has a good quality of image, and such a watermark is difficult to detect and unchangeable without the appropriate user cryptogram.

The use of telecommunications and information technologies in the medicine domain evolved these last years breathtakingly. This involves the development of the applications bound to the telemedicine. Seeing the importance of this discipline in the improvement of the care quality and in the reduction of treatment costs, the optimization of medical applications performances remains a necessity. In this work, we propose a new and efficient cryptocompression scheme applied to the telediagnostic sector for a secure and authentic medical image transmission. Since only 15% of discrete cosine transform components are encrypted in our approach, a significant reduction in processing time during the encryption and decryption, without tampering the high compression rate of the compression algorithm, can be performed by the proposed scheme.

Compressive sensing and chaos based simultaneous compression-encryption of medical images is presented in this paper. A new chaotic map that is highly sensitive to its initial parameters and chaotic in wider range of its control value is proposed. Chaotic behavior of the proposed map is compared with that of the existing logistic map as well. The measurement matrix for compressively sensing the images is constructed based on this proposed map. Also, the initial parameter of the map is used as secret keys in designing the encryption algorithm. Various encryption results are presented to verify the performance of the proposed map and the compression- encryption scheme.
