VOIP PROVIDERS TACKLE SECURITY THREATS UP FRONT
More than 20 companies involved in voice over Internet protocol (VoIP)
tools and technology have formed the VoIP Security Alliance (VOIPSA) to
try to stay ahead of security threats to the emerging VoIP market. "The
same threats on a data network are also inherent in a VoIP deployment,"
said Laura Craddick, a spokesperson for TippingPoint, one of the
founding members of VOIPSA. "Then there are additional risks in VoIP
protocols," she added. With VoIP taking hold in some corporate sectors,
and with household adoption of VoIP technology expected to rise from
400,000 to 12 million over the next five years, analysts warn of the
need to anticipate threats to VoIP networks and prepare for them.
VOIPSA will operate discussion lists, publish white papers, and sponsor
research. Aside from TippingPoint, VOIPSA members currently include
Alcatel, Avaya, Columbia University, and Symantec. Notably absent are
Cisco and Nortel, which the group is actively trying to recruit.

DOES GOOGLE FACE COPYRIGHT TROUBLES?
Google's recently announced plans to scan millions of volumes in
several libraries has some wondering if the project is at risk of
running into copyright limitations. Google will scan books that are in
the public domain and make those texts available online; the company
will also scan copyrighted books and offer short excerpts of a few
lines each. Some publishing groups argued that putting even small
pieces online will violate copyright and that the company should seek
explicit permission from copyright owners. Critics also expressed
reservations about copyright determinations for books that might, for
example, be in the public domain in one country but not in another.
Sally C.L. Morris, chief executive of the Association of Learned and
Professional Society Publishers, said that although the sheer number of
academic publishers represents a powerful disincentive to obtaining
permissions from all of them, "that doesn't mean there's not a legal
requirement to do it." For its part, Google insists that its actions
are acceptable. Google spokesperson Steve Langdon said, "In every case,
Google's presentation of the works to the public will keep authors and
publishers in mind and be well within the bounds of copyright law."

MEDIA LAB FOUNDER PROPOSES INEXPENSIVE LAPTOP FOR EDUCATION
Nicholas Negroponte is developing a sub-$100 laptop computer that he
said could be a vital educational tool for children in developing
countries. Negroponte, the chairman and founder of MIT's Media Lab,
said the idea comes from pilot programs in Maine, in which
schoolchildren were given laptops, and in Cambodia, where he and his
wife have set up two schools and given the students laptops. Children
can use the devices as text books, according to Negroponte, who said
such computers could become "very important to the development of not
just that child but now the whole family, village, and neighborhood."
Negroponte noted that in Cambodia, the students use them not just as
text books but also as "a TV, a telephone, and a games machine."
Building a laptop for less than $100, he said, will require deleting
extraneous applications and running a Linux-based operating system.
"[I]f you can skinny it down," he said, "you can gain speed and the
ability to use smaller processors and slower memory." Negroponte hopes
to start distributing the machines by the end of 2006.

USING IPODS FOR MEDICAL IMAGING AT UCLA
Physicians at the University of California, Los Angeles (UCLA), are
using iPods in conjunction with an open source application developed
in-house to avoid some of the steep costs of medical imaging.
Physicians Osman Ratib and Antoine Rosset created Osirix, an open
source tool that allows radiologists to participate in teleconferences
and see high-resolution medical images on desktop Macintosh computers,
rather than the $100,000 workstations that were previously required.
Files for the 3D images are too large for many media, so Ratib and his
team turned to the iPod, which offers a portable storage medium of
60GB. Although some cautioned that using iPods for storage presents a
security risk, Ratib said the risk is no greater than with any other
medium. "It's not the device, it's how you use it," he said. "When
[users] are outside the institution, they can be compliant or not."
