Google hopes a little browser tool will help change the world.
The company that revolutionized Internet search is now unveiling a sort of online underground tunnel - a way for people in restrictive countries like Iran and Syria to get around digital censorship and surveillance.
The idea behind the tool - essentially a button for browsers - called uProxy, is simple: People in countries such as the United States provide their trusted friends a secure connection so that they can see and use the unrestricted Internet.
Google showed it off earlier this week at a conference called "Conflict in a Connected World." Google also rolled out technology to map cyberattacks around the world, including by repressive governments.
The innovations, from a division of the company called Google Ideas, come at a time when the Internet, and social media in particular, is playing an increasing role in popular upheaval around the world, most notably in the Middle East.
"These are going to be useful additions to the activist toolkit," said Philip Howard, a professor at the University of Washington who has written about the impact of social media on political change.
"Authoritarian governments have started figuring out how to use social media to spy on activists and control political conversation," he said. "Any new tool that lets people network with family and friends in a secure way is likely to have a political impact."
In the two-year civil war in Syria, efforts by opponents of President Bashar Assad to inform the world were met by "unrelenting online repression," according to the free-information group Reporters Without Borders.
Iran has intensified surveillance and jammed Internet lines during periods of unrest. China has censored touchy keywords, including "democracy" and "human rights." Similar but smaller repression took place during uprisings in Egypt and Tunisia.
And just in June, Turkey tightened its grip on Twitter, which it accused of helping people spread lies about the government and terrorize society. It also sought to target "provocateurs" on social media, without giving details.
The uProxy tool essentially provides a mask for dissidents. They can establish a secure connection with someone across the world, in a free-Internet country, whom they trust, and read and post online without surveillance or blocking.
Chinese citizens already use similar connections to get around what is known as the Great Firewall - the government's blocking of much of the Western Internet, including social media sites.
Google calls its way "a safer path to the Internet." David Drummond, a senior vice president at the company, told the conference Monday that Google "was founded on the belief that access to information is a social good."
"More information in more hands means more education, more economic opportunity, more accountability," he said. "Access, in short, is good. And it's why the Internet's so freeing."
In an initiative called Project Shield, Google is also offering to host websites that come under politically motivated shutdown attacks. That initiative is still in testing but has already been endorsed by a popular Persian-language news website.
Google, a company with a market value north of one-third of a trillion dollars, says it's about free expression, not a business interest - in fact the projects are targeted toward many countries under economic sanctions.
It's an interesting move because Google, at least its Ideas division, "sees censorship as Internet damage and wants to route around it," said Danny O'Brien, executive director of the Electronic Frontier Foundation, a nonprofit digital rights group.
The drawback is that it may lead countries to target Google more explicitly, he said.
The tool deliberately avoids Google servers, he said - individual computers act as the middlemen, getting packets of information from repressive countries like Iran and China out to the world.
"But if you put a big Google label on a service like this, you might expect to get blowback," said O'Brien.
A Google spokeswoman declined comment on this concern.
Howard, from the University of Washington, cautioned that getting around Internet censorship is not as simple as building a virtual tunnel. Whether Google's ideas have an equal impact in all repressive regimes remains to be seen, he said.
The Chinese government, for example, has negotiated special treatment from search companies before, and has plenty of money and power to build its own Internet tools. And Russia has poured money into keeping the Internet from being free there.
During the Arab Spring, he said, "We saw how a handful of democracy advocates could use digital media to catch dictators off-guard." But it wasn't long before governments figured out how to use social media for surveillance and censorship.
"It's a running battle," he said.
Sheldon Himelfarb, director of the PeaceTech initative at the United States Institute of Peace, a nonprofit created by Congress to prevent conflict abroad, surveyed the reaction from activists online and said it was positive - "a lot of excitement tempered by mistrust."
He cited the uproar over National Security Agency surveillance programs and doubts about whether the Google initiatives could further open the door for the United States to gather information.
While it's important to remember the risks that come with the new technology, he said, he believes it looks like "good news for Internet freedom."
