In a new report released Monday, a group of lawmakers advised the British government not to make DRM (digital rights management) systems mandatory, citing concerns over how the technology restricts access to digitized files.
The All Party Parliamentary Internet Group (APPIG) said it is not aware of efforts in Europe to make DRM enforced by law, although some publishing groups favor it.
Since November, APPIG has held hearings with book and music publishers, technology companies, and attorneys about how to deal with increasing conflicts and concerns over DRM, releasing a 30-page report on its findings. DRM refers to encoded restrictions on how digital files can be used and manipulated.
Derek Wyatt, a member of Parliament and leader of APPIG, said DRM issues are "under the radar at the moment."
Book and music publishers have strongly supported DRM technology, saying they are needed to protect unauthorized copying and preserve intellectual property. Opponents have charged the measures can be overly strict for those who are legitimately using the digitized works and hamper archiving in libraries.
APPIG is recommending several actions by British regulatory bodies. The U.K. communication regulator, Ofcom, should publish guidelines warning companies of the legal consequences of including invasive DRM technologies, Wyatt said.
Wyatt cited the situation surrounding Sony BMG Music Entertainment, which included copy protection software on an estimated 15 million music CDs. Security experts found last year that the software installed itself without the consent of users, was difficult to remove and secretly communicated with company servers, a type of software commonly known as spyware.
The report also recommended the U.K. Department of Trade and Industry investigate how DRM affects markets. Apple Computer prices songs differently sold through its iTunes music store for the U.K., Europe and the U.S., Wyatt said.
Apple checks the address of credit card holders to prevent purchases outside of a certain region, the report said. The company, which makes the popular iPod music player, uses DRM technology to prevent someone from buying cheaper songs and selling them elsewhere. Apple DRM also limits users to playing songs purchased from the company's iTunes Music Store only on iPods.
At a press conference Monday, the chief executive of the British Library, Lynne Brindley, said the debate over copyright and DRM is heated and polarized, but at stake are enormous resources for the public.
Publishers have become more restrictive in how their works may be used, and the question is at what point will copyright holders relinquish their rights for the public heritage, Brindley said.
"Somewhere the balance has to be found," she said.
The copyright and DRM debate has also focused on a controversial project by Google to digitize books in five libraries in the U.S. and one in England.
