Software publishers and Socialist Party members are among the groups unhappy with the new French copyright law that took effect Friday. French Net surfers could now go to prison for downloading copyright music files without authorization, while companies such as Apple, which make or use digital rights management technology to protect music downloads, may have to provide details of the system to their competitors in the interests of interoperability.

Though the law is intended to protect copyright material, it will, in effect, actually undermine copy-protection efforts, according to The Business Software Alliance (BSA), a group of software publishers. The BSA's main criticism is that the law requires makers of copy protection software to disclose information about their security technologies.

The BSA slammed the law as inconsistent with European intellectual property rules - the very rules that the law is supposed to transpose into French law - and said it stands in stark contrast to France's history as a champion of authors' rights.

For the BSA, the law's requirements for copyright-protection makers also threatens the confidence that consumers have in online commerce. The BSA represents IT companies including Apple, Microsoft, Symantec, RSA Security and SAP. Apple criticized measures in early drafts of the law to mandate DRM interoperability for online music stores as "state-sponsored piracy."

Meanwhile the Socialist Party, the main opposition group in the French parliament, has announced that it will replace the law if it wins power in next year's national and presidential elections.

Socialist Party spokeswoman for media and cultural affairs, Anne Hidalgo, wrote Wednesday that the law fails to balance the rights of content creators with the freedom of choice of Internet users in how they access that content. Content owners want to use DRM technology to protect their products, but consumers should still be allowed to choose the devices or software they use to play such content. DRM systems that aren't interoperable tie them to the platform chosen by the vendor.

While one group sees the law giving too much access to DRM technology, and the other too little, both agree that it's bad for confidence in online business.
