Finding the message within the message is always kind of tricky, especially when no one wants you to discover it. New software developed by Yun Shi, a researcher at the New Jersey Institute of Technology, may help steganographers read between the lines. Steganography is the art and science of hiding information so that nobody but the sender and receiver knows it is there. Cryptography, on the other hand, doesn’t hide a transmission but makes it impossible for an eavesdropper to read it. Shi’s software focuses on hidden messages inside digital files that make up electronic images. These provide good hiding places because images tend to be noisy and complex, providing the perfect background against which a message can blend in. Shi designed software that analyzes the features in noise that may have an image and then looks for elements that do not match those features.

You can't be serious? If you can't tell a recorded disc from an original one with your bare eyes you need to check your glasses.

Electronic gyros are nothing new, they've been around in r/c helis for several years. And they're not very expensive. Cheapest goes for 20 bucks.

Umm.. the difference between a pressed(original) cd and a copy(burned) is that a pressed cd's data (0 and 1) are represented by physical pits and peaks whereas a burned cd's information is represented by burned (reflective and not reflective) marks on a flat plain. Make a system to differentiate peaks (which are reflective, but does not reflect into the target sensor) from non-reflective burn marks. Then you can tell which is a copy, and which is an original.

Great another way to entice road rage... turn the mobile off while blocked in traffic.
