“One response to this has been the rise of technological protection measures (TPM), so-called Digital Rights Management technologies. Digital Rights Management, or DRM, is a technology that enforces a restriction on the use of content after it passes into the hands of the user.”
I'd just as soon not limit DRM to “after it passes into the hands of the user” because in the future we are going to see many of these that don’t allow material to get that far and still act to manage digital rights.Slide3
who’s digital rights managed?
the IP ownership rights of the legal rights owner
the schemes don’t protect the digital rights of users.
Although, big content holders say that the measures protect consumers from breaking the law without knowing it, and/or dissuade them from trying as they would if doing so were easy. Slide4
places/ways to exert control
the physical layer
your
cd/dvd
will not engage at all with/in certain devices
in order to get the “last mile” in a fiber system, we might go to wireless relays that could control access
log on technologies of many sorts)
the code layer
encryption issues
proprietary platform issues
net neutrality issues)
the content layer
“traditional” DRM speed bumps
watermarks
flagsSlide5
strength of control/applied to what functions?
strong
everything you have to the single use we allow. (
dvd
)
moderate
everything you have to multiple uses we allow (
e.g.,downloaded
music)
only some aspects of the thing you have, to single uses (
e.g.,downloaded
movies--free watching, no copying/transfer)
weak
not everything you have and only in some uses. (version file conversions; free play music over networks, etc.)Slide6
in this corner: Pro-drm
if you don’t lock it up, they'll steal it.
user rights? we think users have way fewer rights than they think they do or than they actually do.
audio
cds
can be protected (sort of)
DRM is strongly supported by the DMCA and further extension of it is hotly pursued by big media AND big software.
CSS (and other schemes) lock

loads of folks zero in here with the need for the lock down, ways to do it, and money to be made by doing it.Slide7
drm is HUGE business
“Windows Media Digital Rights Management (DRM) is a proven platform to protect and securely deliver content for playback on computers, portable devices, and network devices. The latest version offers increased flexibility to support a wide range of business models that provide consumers even greater access to protected audio and video content.”

Digital rights Management Standards News from DMR watch

RIAA, MPAA, Software Associations, all want better/moreSlide8
in this corner: con DRM
con: locking it up is often an excessive intrusion on user rights.
con: don't blame users for the lack of user law and don't limit their fair use rights because of that void
con:
rootkit
fiasco . . . generally,
drm
doesn’t work and often violates user rights
neutral but true: No widely distributed DRM scheme has yet actually defeated determined users
DeCSS
(and other such schemes) unlock them

Apple gave up
FTC cautions about how it’s done
loads of folks are "

some of the battlegrounds
analog hole
initially a TV issue, but actually has applicability to all media. Blocking analog to digital conversion interoperability.
conversion to digital (starts with TV)
again, all media are implicated here as if it's digital, it can be (potentially) controlled, maybe.
