The Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md., has opened the door to using reliable digital video as evidence in court by developing a system that identifies an attempt to alter digital video evidence.
"It’s not too hard to make changes to digital video," says Tom Duerr, APL’s project manager. "But our system quickly and conclusively detects any alterations made to the original tape." For the past two years Duerr has led development of the project for the United States Postal Inspection Service.
"We’re satisfied that our system can accurately detect tampering and now we’re building a working prototype that can be attached to a camcorder," says Nick Beser, lead engineer for the project. “Our authenticator provides proof of tampering when the human eye can’t detect it. You might theorize that a change has been made, but this system takes the theory out of that determination."

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
