USE OF INTERNET...............

Today, people  use the Internet for a plethora of reasons;
shopping, chatting,
learning, earning,
job hunting,
marketing, and
even socializing                       Ever since the IT boom of the 1990s, the
Internet has been revered as a source
of information beyond geographical
boundaries. With the dot-com bubble in the
late 90s and more recently with the social
networking phenomenon, we’re beginning to
tap into more and more of the potential of the
Web medium.
Today, people use the Internet for a plethora
of reasons; shopping, chatting, learning, earning,
job hunting, marketing, and even socializing.
However, the most fascinating fact is that most
people do all of this from a single platform.
When Classmates.com and later Friendster
fi rst surfaced, they were limited to the student
fraternity, that too from select schools. A
decade later, it is not just limited to socializing,
but has also emerged as a strong career and
business propagation option as well. A report
from Experian reveals that the medium has fast
grown into an integral part of online business.
Forecasts estimate that $4.3 billion will be spent
advertising through social networks in 2011, a
29% increase from this year.
A look at the users of social networking
websites reveals that India is the seventh largest
market for these websites, behind only the US,
China, Germany, Russia, Brazil and the UK. The
Experian fi nding further states that the average
session time for a user visiting Facebook is 21
minutes and 39 seconds. A survey by TNS Global
of 50,000 Internet users spanning across 46
countries shows that the developing countries
contribute the most to the social networking
phenomenon.

FB cancels phone number sharing

Narrowly avoiding yet another uproar over sharing users' private information with third parties, Facebook
has decided to temporarily
roll back a feature that would grant application developers
access to its users' phone numbers and physical
addresses. The capability will be reintroduced when a more
transparent system for opting out can be implemented. Apps
which use this information will be able to target users
and send notifi cations directly to their phones,
possibly including unsolicited advertisements.

Hackers circumvent industrystandard image signatures


Photos taken with
professional Canon cameras
can be embedded with an
ODD signature (Original
Decision Data). This is
designed to ensure that the
photo cannot be altered or
retouched without being
detected. However Dmitry Sklyarov, a safety expert from
ElcomSoft, has now showed how he can forge this signature,
at the CONFidence 2.0 hacker trade fair. The expert read
out and analyzed the fi rmware of his Canon EOS 30D using
a self-built adapter. He then reverse-engineered the secret
encryption code and was thus able to forge ODD signatures
and deceive the offi cial Canon signature reader, known as
the OSKE3 Security Kit. Canon is aware of this shortcoming
but has not commented on it till now. News agencies and
insurance providers have been using ODD for years in order
to be able to check the authenticity of a photo—such as its
recording time and place. Several controversial photo edits
have made the news in the past few years, embarassing the
responsible agencies and leading to allegations of bias or
manipulation of the news.
