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.

“Matisse makes a drawing, then he makes a copy of it. He recopies it five times, ten times, always clarifying the line. 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)
“Ah! how much a mother learns from her child! The constant protection of a helpless being forces us to so strict an alliance with virtue, that a woman never shows to full advantage except as a mother. Then alone can her character expand in the fulfillment of all life’s duties and the enjoyment of all its pleasures.”
—Honoré De Balzac (1799–1850)
