This paper presents the compression mechanism based on the fractal coding and spiral architecture for the color image data of multimedia applications or system. This compression mechanism can be used prior to the encryption in multimedia system security mechanism. Proposed mechanism falls in lossy compression category. Basically, the fractal coding is applied on the grey level images and encodi...

The usage of Multimedia data has increased by many folds in recent years. And with so many different types of devices available to access the data, it becomes imperative to protect its sanctity. In this paper, a novel lightweight encryption scheme using a secret key has been proposed for multimedia data especially Videos. Chaos based maps has been used to provide an apt level of confusion and d...

Content distribution systems are essentially content protection systems that protect premium multimedia content from being illegally distributed. Physical content distribution systems form a subset of content distribution systems with which the content is distributed via physical media such as CDs, Blu-ray discs, etc. This thesis studies physical content distribution systems. Specifically, we c...

Multimedia information availability has increased dramatically with the advent of video broadcasting on handheld devices. But with this availability comes problems of maintaining the security of information that is displayed in public. ISMA Encryption and Authentication (ISMACryp) is one of the chosen technologies for service protection in DVB-H (Digital Video BroadcastingHandheld), the TV syst...

In recent developments network security and data encryption have become vital and high profile issues. New approaches in encryption techniques are required to be developed for effective data encryption and multimedia applications. For future internet applications on wireless networks, besides source coding and channel coding techniques, cryptographic coding techniques for multimedia application...

In this paper, a new multimedia joint encryption and fingerprinting (JEF) scheme embedded into the advanced access content system (AACS) is proposed for multimedia transmission over networks. AACS is selected because it has been jointly developed by many famous companies and has been considered as the leading technology in content access control and multimedia distribution. In this framework, m...

In this paper we propose a new framework able to ensure security, multimedia quality and energy efficiency in Multimedia Wireless Sensor Networks (MWSNs). The energy is an important and limited resource, which has a direct impact on the lifetime of nodes in MWSNs. In addition, the characteristics of MWSNs like the limited bandwidth and non-deterministic channel access have a significant impact ...

Video command and dispatch systems have become essential communication safeguard measures in circumstances of emergency rescue, epidemic prevention, control as, data security has especially important. After meeting the requirements voice video dispatch, this paper proposes an end-to-end encryption method multimedia information that introduces a multiple protection mechanism including selective ...

Billions of dollars allegedly lost to piracy of multimedia have recently triggered the industry to rethink the way music and movies are distributed. As encryption is vulnerable to re-recording, currently all copyright protection mechanisms tend to rely on watermarking. A watermark is an imperceptive secret hidden into a host signal. In this paper, we analyze the security of multimedia copyright...
