Example text

Consider what happens when a program is installed from an optical media such as a DVD-ROM onto a hard-drive—a copy of the software is made. This happens again when that program is launched—the executable file on disk is duplicated into memory in order for the code to be executed. 19 20 Chapter 1 Trade Secrets and Patents When a new technology is developed, developers are usually faced with two primary options for protecting the unique aspects of it. In some cases, filing a patent is the right choice.

A trade secret legally protects the developer from cases of “trade-secret misappropriation” such as having a rogue employee sell the secret to a competitor. However, a product’s being a trade secret does not protect its owner in cases where a competitor reverse engineers the owner’s product, assuming that product is available on the open market and is obtained legitimately. Having a trade secret also offers no protection in the case of a competitor independently inventing the same technology—that’s exactly what patents are for.

At this point, they received legal threats from SDMI and the RIAA (the Recording Industry Association of America) claiming liability under the DMCA. The team decided to withdraw their paper from the original conference to which it was submitted, but were eventually able to publish it at the USENIX Security Symposium. The sad thing about this whole story is that it is a classic case where the DMCA could actually reduce the level of security provided by the devices it was created to protect. Instead of allowing security researchers to publish their findings and force the developers of the security device to improve their product, the DMCA can be used for stifling the very process of open security research that has been historically proven to create the most robust security systems.
