Entropy-based Object Selection andAutomatic Encryption Mechanism inMPEG-4 Streaming

碩士 === 國立成功大學 === 工程科學系碩博士班 === 92 === 　　This paper presents a new approach to encrypt multimedia data. We adopt entropy to find motion objects, under the assumption that motion objects are more important ones We then encrypt those whose entropy values are higher than a threshold. This new tec...

We adopt entropy to find motion objects, under the assumption that motion objects are more important ones We then encrypt those whose entropy values are higher than a threshold. This new technology can be applied to MPEG-1, MPEG-2 and MPEG-4 standards. The encrypted files conform to original MPEG file formats. This approach only encrypts part of the multimedia data, such that it avoids additional computing overhead, and it can reach real-time processing. Ting-Wei Hou 侯廷偉 2004 學位論文 ; thesis 56 zh-TW
