In present times, Due to the rapidly growth of digital and multimedia applications, more multimedia data are developed and transmitted through the networks in ,art, entertainment, advertising, education, training and commercial areas, which may have important information that should not be accessed by the general users. Therefore issue of protecting the confidentiality, integrity, security, pri...

In the multimedia steganocryptic system, the message will first be encrypted using public key encryption algorithm, and then this encrypted data will be hidden into an image file thus accomplishing both data encoding and hiding. The multimedia data will be used to provide the cover for the information. Visual steganography is one of the most secure forms of steganography available today. It is ...

Multimedia systems mostly base security on a restricted access to services. In the context of real-time imaging applications, this model suffers several drawbacks. Applications become vulnerable to password attacks and once exposed attackers have access to all the data. An alternative consists of the systematic encryption of all data. When dealing with images, this approach is inconvenient beca...

The advent of online social network and mobile multimedia communication has made content sharing in social network easier and more efficient. It is very important to combine fingerprinting and encryption for social multimedia content protection. In this paper, a parallel JFE (joint fingerprinting and encryption) framework is proposed. Firstly, the multi-level social fingerprint code is produced...

The traffic of digital images has grown rapidly in the Internet. Security of image becomes important for many sectors mainly for medical applications. Nowadays, the transmission of medical images is a daily routine, especially over wireless (battlefields, traffic accidents, etc). Partial encryption is an approach to reduce the computational resources for huge volumes of multimedia data in low p...

The Fractional Fourier Transform (FRFT) has been playing a unique and increasingly important role in signal image processing. In this letter, we investigate the property of frequency shift two-dimensional FRFT (2D-FRFT) domain. It is shown that magnitude reconstruction from phase information shift-invariant 2D-FRFT domain, enhancing robustness encryption, an multimedia security task. Experiment...

In medical information systems, image data can be considered crucial information. As imaging technology and methods for analyzing images advance, there will a greater wealth of available study. Hence, protecting those is essential. Image encryption are in multimedia applications ensuring the security authenticity digital images. Recently, has garnered significant attention from academics due to...

In an age when information exchange has been made more mobile by the advent and advances in internet technology, information security is assuming a worrisome dimension. Hacking, phishing, eavesdropping, scamming and a host of other vices have become the order of the day on communication channels. This research addresses the problem of data security on multimedia systems by proposing a cascaded ...

Local binary pattern (LBP) operators, which measure the local contrast within a pixel's neighborhood, successfully applied to texture analysis, visual inspection, and image retrieval. In this paper, we recommend a semi blind and informed watermarking approach. The watermark has been built from the original image using Weber Law. The approach aims is to present a high robustness and imperceptibi...
