Intrinsically Embedded Signatures for Multimedia Forensics

2016
This dissertation examines the use of signatures that are intrinsically embedded in media recordings for studies and applications in multimedia forensics. These near-invisible signatures are fingerprints that are captured unintentionally in a recording due to influences from the environment in which it was made and the recording device that was ...

Digital Multimedia Forensics and Anti-Forensics.

2012
As the use of digital multimedia content such as images and video has increased, so has the means and the incentive to create digital forgeries. Presently, powerful editing software allows forgers to create perceptually convincing digital forgeries. Accordingly, there is a great need for techniques capable of authenticating digital multimedia content ...

Traitor Tracing for Multimedia Forensics

2011
This chapter discusses the cryptographic traitor tracing technology that is used to defend against piracy in multimedia content distribution. It talks about different potential pirate attacks in a multimedia content distribution system. It discusses how traitor tracing technologies can be used to defend against those attacks by identifying the ...

Multimedia Forensics Using Metadata

The rapid development of machine learning techniques makes it possible to manipulate or synthesize video and audio information while introducing nearly indetectable artifacts. Most media forensics methods analyze the high-level data (e.g., pixels from videos, temporal signals from audios) decoded from compressed media data.

Time and Location Forensics for Multimedia.

2013
In the modern era, a vast quantities of digital information is available in the form of audio, image, video, and other sensor recordings. These recordings may contain metadata describing important information such as the time and the location of recording. As the stored information can be easily modified using readily available digital editing software,
