Adobe bends, a little, on eBook DRM

Responding to criticism that its anti-piracy mechanisms could slow the growth of the e-book industry, Adobe Systems plans to liberalise its approach toward Digital Rights Management (DRM) with e-books.

The next major version of its Content Server software will give book publishers, authors and libraries the option to protect encrypted e-books with a password.

Seemingly minor, the move is important both because of Adobe’s growing behind-the-scenes importance in the burgeoning e-book industry, but also in how it moves ahead with content protection.

The current Adobe Content Server 4 software lets publishers choose whether or not to encrypt their e-books. It also lets e-book buyers choose up to 12 devices — six desktop and six handhelds, including e-book readers or smartphones—on which they can read e-books protected by encryption.

That number is meant to give owners flexibility to move purchased e-books among various devices.

But what if people want to share their e-books with a relative, close friend or colleague? Content Server 5 will allow that by letting owners link e-books to an Adobe ID account. Users would then enter in a username and password to open up and read a book on any device or PC.

On the flip side, that means a cracked Adobe ID and password could be distributed and used to let pirates read an e-book, just as stolen license keys are used to enable the installation of pirated software.

That possibility is why publishers want Adobe to provide the option for weak or strong encryption, said Nick Bogaty, senior business development manager for digital publishing at Adobe. “I think it’s legitimate concern on publishers’ part to make it somewhat difficult to mass copy their files, and that’s what our DRM does,” he said. “Their business is copyrights, and if they don’t have that, they don’t have a business anymore.”

Some critics point out that Adobe, by promoting its flavour of encryption on top of the open ePub standard, is promoting a version of vendor lock-in. Users will be forced to rely on Adobe’s e-book-reading software — either Digital Editions for PCs, or Adobe Mobile Reader on smartphones, E-Ink devices and tablets — to read their e-books.

Critics also say that DRM measures remain confusing and unnatural for consumers.

“Publishers always feel better if things are locked down, but consumers can’t stand it,” says David Rothman, editor of the e-book-focused blog, TeleRead.

Rothman is an advocate of “social DRM” techniques, such as watermarking e-books with the owner’s name and address, rather than preventing their redistribution. “It’s using the forces of peer pressure in a good way. But Adobe keeps wanting to think in terms of encryption,” he said.

And that could stunt the e-book market, which remains small. Wholesale trade in e-books in the U.S. for the first three quarters this year totaled $US110 million ($A121m), according to the International Digital Publishing Forum (IDPF). While that is up more than three-fold from last year, it remains a fraction of the paper-based publishing market.

Rothman and others point to the music industry, where some artists and record companies and retailers are starting to favour audio watermarks over DRM, employ P2P networks to give away songs for radio-like promotion, or substituting CD sales with concert tours and merchandise sales.

Adobe’s Bogaty, the former executive director of IDPF, is sceptical that such a revenue model would work in the book publishing business. “Until I see a book reading fill up Madison Square Garden, or a bunch of kids wearing Tom Wolfe t-shirts, I just don’t see a big ancillary market for publishers,” he said.
