How does copy protection work?
Copy protection (sometimes erroneously referred to as “copyright protection”) is a feature of a product that increases the difficulty of making an exact duplicate. The goal is not to make it impossible to copy — generally speaking, that can’t be done — but rather to discourage “casual copying” of software and music. The goal is *not* to conceal information from prying eyes; see section (3-19) for information on encrypting data on a CD-ROM. A separate but related issue is “counterfeit protection”, where the publisher wants to make it easy to detect mass-produced duplicates. An example of this is Microsoft’s placement of holograms on the hubs of their CD-ROMs. There are full CD pressing plants dedicated to creating counterfeit software (the worst offender being mainland China), so this is a serious concern for the larger software houses. Copy protection on CD-ROMs used to be rare, but as the popularity of CD recorders grew, so did the popularity of copy protection.
