When was a video captured? Where? Was the sound track captured together with the visual? Or added on later? Check out our latest work exploring environmental fingerprint from power grid and many other types of micro signals:

I chaired the IEEE Technical Committee on Information Forensics and Security (IFS-TC, 2012-2013), and have been an IEEE Fellow since 2011 and an AAAS Fellow since 2017 [UMD news].
I completed my 3-year term as Editor-in-Chief of the IEEE Signal Processing Magazine (2015-2017), and earlier I served as Founding Chief Editor of the IEEE SigPort online repository and Area Editor of the SPM for creating and editing the monthly "Inside Signal Processing eNewsletter (2007-2010)."
A special issue on "Digital Forensics" that I edited with colleagues in the IFS-TC appeared in the IEEE Signal Processing Magazine (SPM) in March 2009. An article on "Component Forensics" framework I co-authored was also translated to Chinese as an outreach effort of SPM. [IEEE Xplore, PDF; 中文版]
The paths of engineering and economics/management -- the two college majors I pursued -- crossed again 10 years since graduation, when I served as Finance Chair for IEEE's flagship conference on signal processing -- ICASSP'07. Later I served as Vice President - Finance of the IEEE Signal Processing Society (2010-2012).
I have been the Principal Investigator or Co-PI for several basic and advanced research projects funded by the Department of Defense on information security and forensics. Learn more from my research page.
A recent 3-year NSF effort of "Fashion," or Forensic Hash for Assured Cyber-based Sensing and Communications, aims at exploring the synergy between multimedia hashing and non-intrusive forensics [UMD news]. Earlier, I had a 3-year NSF effort focuses on addressing physical-layer challenges through cross-layer approaches to wireless secure communications, dubbed as the CLAWS effort [UMD news], and my research on "Signal Processing Approaches for Multimedia Security and Information Protection" was sponsored by NSF through a 5-year CAREER award program ('02-'07) [E@M Magazine news]). Learn more about our earlier reserach on Embedded Digital Fingerprints funded by the basic research program by the U.S. Depeartment of Defense.
My book, "Multimedia Data Hiding", (co-authored with Prof. Bede Liu, Springer-Verlag, 2002), addresses both fundamental and practical issues, and tackles both design and attack problems. [Available at Amazon.com and Barnes&Nobles]
I also coauthored a book on "Multimedia Fingerprinting Forensics for Traitor Tracing " in Fall 2005 (EURASIP Book Series, by Hindawi Publishing).
