Canadian New Media: Copyright Act protection for rights management inappropriate

An article I wrote for Canadian New Media was published today.

Both Henderson's suggestion for subscription radio and Bill C-60 is to propose to mandate or legally protect technological protection measures (TPMs) that claim to protect copyright. Henderson claims there are relatively inexpensive and simple technological fixes to accomplish his goals. When a technology vendor claims they can stop people from copying works without permission, we must ask how they accomplish this goal.

While TPMs can provide access control and authenticity, they can't directly control the creation of copies. All so-called "copy control" technologies either use access controls (like the technique used on DVD movies), or deliberate defects in the media (used on some music CDs) that behave certain ways with specific access technology.
