Joint Video Compression and Encryption (JVCE) has gained increased attention in the past couple of years to reduce the computational complexity of video compression, as well as provide encryption of multimedia content for web services. In this paper, we present a JVCE framework based on Binary Arithmetic Coding (BAC). We first present an interpretation of BAC in terms of a skewed binary map and then...
H.264 video applications based on mobile handheld devices are becoming more and more popular. How to protect the security has become an important topic. However, the significant power consumption of video encryption algorithms executing the limited battery capacity of handheld devices restricts the abroad use. In this paper, we propose a low power partial encryption scheme based on H.264, it combines...
This paper presents a novel method for the protection of copyrighted multimedia content. The problem of selective encryption (SE) has been addressed along with compression for the state of the art video codec H.264/AVC. SE is performed in the context-based adaptive binary arithmetic coding (CABAC) module of video codec. For this purpose, CABAC is converted to an encryption cipher by scrambling of...
Due to traditional and single video encryption algorithms canpsilat meet the needs of various net multimedia services. This paper references the H.264 video coding standard and video encryption algorithms, analyzes the existing video encryption algorithms from security, speed, compression ratio and date operability, and classes the video encryption algorithms according to security. It also proposes...
With the rapid development of the mobile communication technology, multimedia transmission over mobile network has become a hotspot in the monitoring area. We propose an application of the embedded Linux system and CDMA1X wireless data transmission technology in the video surveillance system. It is also a general model of wireless video capture and transmission based on embedded Linux and CDMA1X network...
The fast growing progress in data communication leads to a wide variety of available access technologies that provide everything from mobile data transfer to high-speed data links using fibre optics. Due to this fact multimedia contents, which have to be transmitted, have to be adapted every time the connection parameters are changing. Fortunately, modern video coding standards are able to deliver...
