Compact Disc And DVD Copy Protection
CD/DVD copy protection is a blanket term for various methods of copy protection for CDs and DVDs. Such methods include DRM, CD-checks, Dummy Files, illegal tables of contents, over-sizing or over-burning the CD, physical errors and bad sectors. Many protection schemes rely on breaking compliance with CD and DVD standards, leading to playback problems on some devices.
Protection schemes rely on distinctive features that:
- can be applied to a medium during the manufacturing process, so that a protected medium is distinguishable from an unprotected one.
- cannot be faked, copied, or retroactively applied to an unprotected medium using typical hardware and software.

He’s convinced that the last, the most stripped down, is the best, the purest, the definitive one; and in fact, most of the time, it was the first. In drawing, nothing is better than the first attempt.”
—Pablo Picasso (1881–1973)
“The best protection parents can have against the nightmare of a daycare arrangement where someone might hurt their child is to choose a place that encourages parents to drop in at any time and that facilitates communication among parents using the program. If parents are free to drop in and if they exercise this right, it is not likely that adults in that place are behaving in ways that harm children.”
—Gwen Morgan (20th century)
