Non-Intrusive Media Forensics Framework.

摘要

In recent years, the availability of high-quality digital cameras and audio recording devices coupled with the rise of the Internet as a means of information delivery has cause digital content to become prevalent throughout society. Many governmental, legal, scientific, and news media organizations rely on digital multimedia content to make critical decisions or to use as evidence of specific events. This proves to be problematic, as the rise of digital media has coincided with the widespread availability of digital editing software. At present, a forger can easily manipulate digital content such as images or video to create perceptually realistic forgeries. To avoid both embarrassment and legal ramifications, many of these organizations now desire some means of identifying alterations to digital multimedia content and verifying its authenticity. As a result, the field of digital multimedia forensics has been born.
