Copy protection is not new, but has been given a new lease on life with the commercialization of the Internet. Old-world media companies want to sell their wares over digital networks, but want to control their use. Limiting resale, preventing copying, pay-per-use: these are all differnet ways of limiting what a consumer can do with a digital file after he or she receives it on his or her computer. Many different products purport to solve these problems, but they all fail. Making digital files uncopyable goes against the natural laws of digital content. In this talk, I will discuss these laws, explain why all copy-protection mechanisms fail technically, and describe some of the non-technical solutions media companies are pursuing.
