Google emails highlight value of location data

Larry Page's Memorial Day weekend email was terse -- "Can I get a response
on this?" -- but the scramble it set off among top Google (GOOG) executives
on a Saturday afternoon illustrates the critical importance the company
places on the data its smartphones use to track their location.

Page had pasted an article in the email saying Motorola planned to use a
competitor's location services in its phones. A detailed memo quickly came
back to Page, Android chief Andy Rubin and other Google executives that not
only said collecting location data from consumers' smartphones was
"extremely valuable to Google," but detailed how the company's problems with
data collection stemmed from a privacy blow-up last spring involving
Google's Street View cars.

"I cannot stress enough how important Google's wifi location database is to
our Android and mobile product strategy," Google location service product
manager Steve Lee wrote. "We absolutely do care about this (decision by
Motorola) because we need wifi data collection in order to maintain and
improve our wifi location service."

Following the privacy furor sparked last week by the discovery of a hidden
tracking file on Apple's

(AAPL) iPhones and iPads, Google and Apple executives are scheduled to
testify before the Senate Judiciary Committee May 10 about how they use
information gathered by smartphones to power their location services.

Those services are vast digital databases that include the physical location
of hundreds of millions of Wi-Fi access points. Smartphones use those
databases as a kind of electronic map to chart their own location in space,
allowing phones to run apps like Foursquare that demand a specific location.

To build those maps, Google and Apple need location data fed from millions
of consumer smartphones that report the location of the Wi-Fi access points
they encounter as users move around each day. Accurate location services
also are critical for companies like Google and Apple to deliver
location-based ads to smartphones -- projected to become a multi-billion
dollar business for those companies.

"Information about the location of WiFi networks improves the accuracy of
the location-based services, such as Google Maps or driving directions, that
Google provides to consumers," Google explained last year in a letter to
U.S. Rep. Henry Waxman of California. "Because GPS and cell tower data can
be unreliable or inaccurate, in some cases using the location of Wi-Fi
access points can enable a smartphone to pinpoint its own location more
quickly and accurately."

The May 29 email exchange between Lee, product executives Jonathan Rosenberg
and John Hanke, Rubin and Page, who is now Google's CEO, happened in the
space of 68 minutes late Saturday afternoon. The email exchange, which this
newspaper obtained, is detailed in court records as part of a lawsuit by
Skyhook Wireless, a Boston company that has provided location services for
Google and Apple. Google declined to comment on the emails.

Last year's Street View privacy controversy began when Google was forced to
admit that its Street View cars had inadvertantly scooped up data from
unsecured home and business Wi-Fi networks in the U.S. and other countries.

The mission of the Street View cars, Google has said, was to map the
location of Wi-Fi networks, not to store so-called "payload data" from them.
The Street View data breach, which resulted in an apology from Google
executives and investigations by regulators in the United States and Europe,
was revealed just two weeks before Page's May 29 email.

Lee's response said Google's decision after the privacy breach to stop using
Street View cars to map Wi-Fi networks made the need for smartphone data all
the more crucial to its location database.

Google had used Street View cars and phone data since 2007 to map Wi-Fi
access points and by last year, Lee said, it had logged the location of over
300 million of them, a vast geographical database that could be used to
pinpoint a smartphone user's location with an accuracy of about 98 feet.

Google says no location data is collected through Android phone unless users
explicitly give permission when they are setting up a new phone.

"All location sharing on Android is opt-in by the user," Google said in a
written statement Thursday."We provide users with notice and control over
the collection, sharing and use of location in order to provide a better
mobile experience on Android devices. Any location data that is sent back to
Google location servers is anonymized and is not tied or traceable to a
specific user."

The opt-in question comes when users are setting up their Android phone,
when users are asked to check a box that reads: "Allow Google's location
service to collect anonymous location data. Collection will occur even when
no applications are running." If they opt-in, users have the option to later
turn off data collection at any time, Google said.

Skyhook sued Google last fall in state court in Massachusetts, charging that
Google interfered with Skyhook's contractual business relationship with
Motorola by pressuring the phone manufacturer to use Google's location
service exclusively instead of allowing both Google and Skyhook's location
services to run on Motorola phones.

Skyhook, which still provides location services for Apple devices like the
iPod Touch running older versions of its operating system, also sued Google
for patent infringement in federal court, claims in the state suit that it
suffered damages "that exceed tens of millions of dollars." The state and
federal cases are pending.

What is wrong with our education system? asks SDP's Teo

Citing the statistic that 97 out of 100 students have to receive tuition on
top of attending school, Singapore Democratic Party (SDP) candidate for
Yuhua single-seat ward Teo Soh Lung, 62, posed this question to her direct
opponent, the People's Action Party's (PAP) Grace Fu, who is Senior Minister
of State for National Development and Education: What is wrong with the
education system?

Speaking at the SDP rally in Jurong East Stadium on Friday night, Ms Teo, a
retired lawyer, said: "Singapore is known as a 'tuition nation'. I want to
ask the minister what is wrong with our system and I hope to receive an
answer very soon."

The problem, said Ms Teo, was that parents spend "as much as S$500 a month"
on tuition fees. She also lamented having too many students in a classroom
managed only by one teacher. "How come after over 50 years of PAP rule we
still have 40 students in a class and not 20 students in a class - as in a
First World nation? I feel so sad that the system has deteriorated."

Ms Teo pledged to become a full-time Member of Parliament (MP) if elected.
"I will service you with my utmost ability ... My fellow colleagues will
also assist me. My party and I are fully aware that we have plenty to do ...
We are determined to make a difference for you."

She also said "SDP MPs would donate 50 per cent of allowance to service the
residents", with programmes such as "an endowment fund for the needy". She
also said she would seek to abolish the Goods and Services Tax (GST) for all
essential goods, help reduce the cost of living and strive to introduce a
minimum wage system for Singapore.

Her concerns were echoed by the SDP's Dr Vincent Wijeysingha, who also
called for a reduction in classroom size. "Let us bring new ways of
educating our children in smaller classrooms so that they become the
creative and innovative people of tomorrow," he said.

Dr Wijeysingha, who is part of the SDP team contesting in the Holland-Bukit
Timah Group Representation Constituency, added: "And let us guarantee every
worker a minimum wage. And if you think a minimum wage is going to bankrupt
our economy, 173 countries of the world have minimum wage. China has a
minimum wage. We can afford to pay our young people and hardworking elders
enough money for them to live, not just to survive."

William and Kate's World Wide Wedding

The marriage of Prince William and Kate Middleton was an event for the
internet age.

Great traditions of state were celebrated by the modern institutions of the
web.

Facebook, Twitter, Google and YouTube were all given over to the royal
wedding.

And, like the streets around Westminster Abbey, cyberspace was buzzing with
talk of the big day.

Leading the online celebrations was the British monarchy's own royal wedding
website.

Visitors were directed to the official Clarence House Twitter feed, the
royal Flickr photo account, and the wedding "event" page on Facebook.

Royal tweets

Throughout the ceremony, @ClarenceHouse tweeted updates:

"The Archbishop of Canterbury begins the solemnization of the marriage
#rw2011"

"The Fanfare plays! Congratulations to The Duke and The Duchess of
Cambridge! You can use our hashtag #rw2011 to send a message #royalwedding"

"The view of the couple arriving at Buckingham Palace from where we are
based #rw2011http://twitpic.com/4qxlhn"

"The Duke and The Duchess of Cambridge appear on the balcony #rw2011"

"Find out about the food being eaten at the lunchtime wedding
receptionhttp://bit.ly/jUHKup #rw2011"

Trending topics

Talk of the wedding dominated Twitter, not just in the UK, but around the
world.

The micro blogging site's top "trending topics" globally were all
royal-themed.

Royal channel

While blogs and social networking sites provided users with a way of sharing
their thoughts on the royal wedding, the internet also allowed people to
watch the ceremony.

YouTube's live feed brought the BBC's pictures to a global online audience
through the "Royal Channel".

It was the video sharing site's 23rd most-visited channel of the day, but
trailed behind America's Next Top Model and Top Gear.

The BBC website, which also streamed the occasion, at one point experienced
technical issues caused by "the sheer weight of traffic".

Many TV broadcasters also live streamed the wedding to mobile devices,
including smartphones and tablet PCs.

Facebook figures

The world's largest social networking site, Facebook was quick to extract
wedding statistics from its more than 500 million users.

Some of the more choice nuggets of information include:

684,399 status updates mentioned the royal wedding over a four hour period -
roughly 47 per second.
2,274 users checked-in at Westminster Abbey using Facebook's "Places"
feature.
A Facebook page dedicated to "Princess Beatrice's Ridiculous Royal Wedding
Hat" gained over 4,000 fans.

Web traffic

Measuring the scale of a global media event is notoriously difficult.

The number of TV viewers has been estimated at around two billion. In
reality, that is little more than an educated guess.

Quantifying the popularity of a topic on particular sites, such as Facebook
and Twitter is possible.

However, it is difficult to gauge the impact on the internet overall.

At the height of the wedding, global web traffic, as measured by Akamai, was
39% higher than normal.

Although there is no firm evidence that this was due to the wedding, the
United Kingdom was listed as a hot spot, with the country accounting for 11%
of online activity.

Republican option

Such was the mood of global celebration that not even the notorious "Great
firewall of China" was set to filter out information about William and
Kate's nuptials.

The story, along with a picture of the bride and groom, topped the news page
of the country's most popular search engine, Baidu.

Brits seeking a wedding-free news source had to look closer to home.

Refuge was to be found on the website of the Guardian Newspaper.

Visitors to the publication's homepage were presented with the option of a
"royalist" version, complete with blanket coverage, or a "republican"
version, devoid of the merest mention of William, Kate or Tara Palmer
Tomkinson's hat.
