Silent Skype calls can hide secret messages









































Got a secret message to send? Say it with silence. A new technique can embed secret data during a phone call on Skype. "There are concerns that Skype calls can be intercepted and analysed," says Wojciech Mazurczyk at the Institute of Telecommunications in Warsaw, Poland. So his team's SkypeHide system lets users hide extra, non-chat messages during a call.












Mazurczyk and his colleagues Maciej Karaƛ and Krysztof Szczypiorski analysed Skype data traffic during calls and discovered an opportunity in the way Skype "transmits" silence. Rather than send no data between spoken words, Skype sends 70-bit-long data packets instead of the 130-bit ones that carry speech.












The team hijacks these silence packets, injecting encrypted message data into some of them. The Skype receiver simply ignores the secret-message data, but it can nevertheless be decoded at the other end, the team has found. "The secret data is indistinguishable from silence-period traffic, so detection of SkypeHide is very difficult," says Mazurczyk. They found they could transmit secret text, audio or video during Skype calls at a rate of almost 1 kilobit per second alongside phone calls.












The team aims to present SkypeHide at a steganography conference in Montpellier, France, in June.

Football: Transfer talks stall for AC Milan's Robinho






MILAN: AC Milan's bid to sell Robinho to Brazilian top flight side Santos floundered early on Saturday after the clubs failed to agree on a transfer fee, it was reported.

Milan have slapped a 10m-euro price tag on the talented Brazilian while Santos offered only seven million, according to ANSA news agency.

ANSA also reported that another Brazilian side that had shown an interest in purchasing Robinho, Atletico Mineiro, had now called off talks.

Citing Brazilian newspaper Folha de Sao Paulo, it said Atletico could not meet Milan's 10m euro asking price nor Robinho's wage demands.

Milan's former Brazilian striker Alexandre Pato on Thursday joined Brazilian side Corinthians in a four-year deal thought to be worth 15 million euros.

The Serie A giants sit seventh in Serie A, 17 points adrift of leaders Juventus, ahead of the visit of Siena on Sunday.

Library of Congress digs in to full archive of 170 billion tweets



The U.S. Library of Congress said today that it has completed a process of collecting a full, ongoing stream of tweets, and that it has begun work to archive and organize more than 170 billion tweets.




Under an agreement struck between the government institution and Twitter in 2010, the microblogging company is providing the Library of Congress with a full stream of all public tweets, starting with 21 billion generated from between 2006 and April 2010, and now supplemented with about 150 billion more posted since then.


In an announcement about the status of the project today, the library wrote that:


Twitter is a new kind of collection for the Library of Congress but an important one to its mission. As society turns to social media as a primary method of communication and creative expression, social media is supplementing, and in some cases supplanting, letters, journals, serial publications, and other sources routinely collected by research libraries.


Though the Library has been building and stabilizing the archive and has not yet offered researchers access, we have nevertheless received approximately 400 inquiries from researchers all over the world. Some broad topics of interest expressed by researchers run from patterns in the rise of citizen journalism and elected officials' communications to tracking vaccination rates and predicting stock market activity.


The Library of Congress isn't entirely clear how the ongoing archive will be utilized, but it has issued a white paper (PDF) outlining the project.


This project, of course, is different than Twitter's recently announced initiative to make every user's full tweet history available to them. That effort is under way, though only some users have been given access to date.


Interestingly, the Library of Congress reported in the white paper that its two full copies of the entire archive of 170 billion tweets comprise about 133 Terabytes of data. Each tweet, the library wrote, contains about 50 accompanying metadata fields.

Debt Limit Negotiating Tactic? No Negotiating


ap obama ac 130102 wblog In Fiscal Wars No Negotiation Is a Negotiating Tactic

Analysis


New for 2013: In the Washington, D.C. fiscal wars we’ve gone from everything must be on the table to politicians declaring they won’t debate.


The fiscal cliff deal either averted disaster or compounded the problem, depending on who you ask. It certainly created new mini-cliffs in a few months as Congress and the president square off on the debt ceiling, spending cuts and government funding. But it also made sure the vast majority of Americans won’t see as big a tax hike as they might have.


President Obama was pretty clear late on New Year’s night as he reacted to Congress’s passage of a bill to take a turn away from the fiscal cliff. He won’t negotiate with Republicans about the debt ceiling.


“Now, one last point I want to make,” said the president, before wrapping up and hopping on Air Force One for a redeye to Hawaii. “While I will negotiate over many things, I will not have another debate with this Congress over whether or not they should pay the bills that they’ve already racked up through the laws that they passed.”


(Read more here about the Fiscal Cliff)


That’s pretty clear. No debt ceiling negotiation. Then he added for emphasis: ”Let me repeat: We can’t not pay bills that we’ve already incurred. If Congress refuses to give the United States government the ability to pay these bills on time, the consequences for the entire global economy would be catastrophic — far worse than the impact of a fiscal cliff.”


But in Washington, saying you won’t do something these days has almost become like an opening bid. At least, that’s how Republicans are treating the president’s line in the sand.


“The president may not want to have a fight about government spending over the next few months, but it’s the fight he is going to have because it’s a debate the country needs,” wrote Senate Minority Leader Mitch McConnell, the Kentucky Republican, in an op-Ed on Yahoo! News about 36 hours later. “For the sake of our future, the president must show up to this debate early and convince his party to do something that neither he nor they have been willing to do until now.”


“We simply cannot increase the nation’s borrowing limit without committing to long overdue reforms to spending programs that are the very cause of our debt,” McConnell said.


The national debt is soon set to reach $16.4 trillion. That’s not a problem that can be solved with one bill or budget. And the two sides will have to figure out some sort of way to talk about entitlement/social safety net reform – meaning things like Medicare, Medicaid, and Social Security – in addition to cutting spending and, most importantly, hope for an improving economy, to deal with those deficits.


House Speaker John Boehner, who has several times now failed to reach a big, broad fiscal deal with President Obama, told colleagues, according to The Hill newspaper, that he’s done with secret White House negotiations. He wants to stick with the constitutional way of doing things, with hearings and bills that are debated on Capitol Hill rather than hatched by the vice president and Senate Republicans.


Okay. Obama won’t negotiate on the debt ceiling. McConnell won’t not negotiate on the debt ceiling. Boehner doesn’t to do things by the book.


But McConnell won’t negotiate on taxes any more.


“Predictably,” McConnell had written earlier in his post, “the president is already claiming that his tax hike on the ‘rich’ isn’t enough. I have news for him: the moment that he and virtually every elected Democrat in Washington signed off on the terms of the current arrangement, it was the last word on taxes. That debate is over.”


It’s a new chapter in the ongoing fiscal saga in Washington. Back when the two sides were talking about a grand bargain or a big deal – some sort of all-inclusive reform that would right the listing deficit with one flip of the rudder – the popular trope was that “everything must be on the table.” That’s basically how Obama put it back in the summer of 2011 when he and Boehner failed to reach a grand bargain. He wanted higher taxes – they were calling them revenues back then. More recently, after Obama won the election and when he and Boehner were trying to hammer out another grand bargain to avert the fiscal cliff, Boehner wanted entitlements on the table. That means he wanted to find ways to curb future spending.


Both sides are declaring they won’t debate certain points, but this far – a full two months – before the mini-cliffs start, those are easier declarations to make than they will be when the government is in danger of defaulting or shutting down.


Even though they’re trying to take elements off the table, both men hope that coming negotiations can be a little more cordial and a little less down-to-the wire.


“Over the next two months they need to deliver the same kind of bipartisan resolution to the spending problem we have now achieved on revenue — before the 11th hour,” wrote McConnell.


“The one thing that I think, hopefully, in the New Year we’ll focus on is seeing if we can put a package like this together with a little bit less drama, a little less brinksmanship, not scare the heck out of folks quite as much,” said Obama.


That’ll be tough if neither side will talk about what the other side wants to talk about.

King speaks to sceptical Spaniards






MADRID: After a year blighted by embarrassing scandals, Spain's King Juan Carlos moves to repair his damaged reputation Friday with the broadcast of a rare televised interview to mark his 75th birthday.

No details of the pre-recorded interview had leaked from the royal palace ahead of its airing on Friday evening, but Spanish media trailed it by scrutinising the recent tribulations of the king, a key player in Spain's modern history.

Juan Carlos has recently appeared hobbling around on crutches after having both hips replaced, but any sympathy for his health has been overshadowed by scandals over elephant-hunting in Africa and a corruption probe implicating his family.

In a poll published Thursday by El Mundo newspaper, only half of people expressed a positive judgement of his reign, compared with three-quarters a year ago.

Juan Carlos, who turns 75 on Saturday, won respect in Spain for helping guide it to democracy after the death of dictator Francisco Franco in 1975.

But the king's image suffered last year from two scandals.

The first was a corruption case against his son-in-law Inaki Urdangarin, the duke of Palma, who went before a judge in February.

The other was an expensive game-hunting trip the king himself made to Botswana, seen as an unacceptable extravagance while Spain suffered in a recession.

Thursday's poll showed general support for having a monarchy in Spain has fallen to 54 percent, six points down from a year ago and "a historic low", according to the newspaper.

For days ahead of the interview broadcast, national television has aired old footage including Juan Carlos's solemn address, dressed in his officer's uniform, condemning an attempted coup on February 23, 1981.

A generation after those historic events, the poll found that nearly 58 percent of people aged between 18 and 29 said they thought a monarchy was not the best form of governance for Spain.

El Mundo suggested people of this generation do not share their parents' reverence for the king since they "did not live through the transition and are not very interested in it".

In his annual Christmas speech to the nation, Juan Carlos called on Spaniards to unite against the current economic crisis that has thrown millions out of work.

"We cannot ignore that there is pessimism, and that its effects are felt in the social climate we are living in," the king said, after a year of mass street demonstrations and two general strikes.

Of all the measures to combat the crisis, "the main stimulus that will get us out of this crisis is called confidence," he said in the speech, in which he made a point of appearing without crutches, standing beside his desk.

Observers saw this as one in a series of efforts to strengthen the monarchy's standing.

"The royal palace has launched in recent months a studious marketing operation to improve the image of the king," El Mundo wrote in an editorial.

In this week's poll nearly 45 percent of people questioned said Juan Carlos should abdicate to make way for his son, Felipe, 44.

Qualcomm to demo first StreamBoost Wi-Fi routers at CES 2013



StreamBoost-based routers help you visualize and manage Internet bandwidth.

It's frustrating when you share the Internet between multiple devices and some of them hog all the bandwidth, leaving the rest crawling. Qualcomm has something that potentially ease this pain.




The mobile chip maker today introduced its StreamBoost technology, which is designed to "optimize performance and capacity of home networks" by enabling the home router to intelligently manage the broadband connection. Qualcomm says the new technology allots to each connected device and each application the bandwidth it needs, and no more, to ensure the best possible experience on all connected devices.


It's important to note that StreamBoost is quite different from existing Quality of Service (QoS) technology, available in many routers, that can do a similar thing. StreamBoost tailors the Internet bandwidth to make sure the prioritized application has the exact amount of bandwidth it needs at a given time, Qualcomm says, rather than a percentage of download priority at all times. This results in more bandwidth being left for the rest of the connected devices.


Another feature of StreamBoost is that it can automatically "learn" over time the Internet-related characteristics of an application and changes the way its prioritization works accordingly. This is important since Internet-based applications tend to evolve rapidly. Youtube, for example, now offers more streaming options than it did a year ago. User can opt in to a cloud-based feature to contribute to making StreamBoost smarter. And if they choose to do so, they can also use it to manage their home network remotely and update how StreamBoost works dynamically, rather than via firmware revisions.



If StreamBoost works out as Qualcomm claims, it might just be one of the most significant new home networking features for 2013, since currently the average home connects some seven devices to the Internet and this number is expected to only increase.


StreamBoost is a software service that technically can be used in any router. However, for now, it's only available in those that are based on Qualcomm's new VIVE 802.11ac chip. This, Qualcomm's first 802.11ac chip, offers up to 1.3Gbps Wi-Fi data rates and is the second 802.11ac chip on the market, in addition to the one Broadcom introduced last year.


Qualcomm says it will be demoing StreamBoost at CES 2013, in collaboration with D-Link and Alienware. If you can't get to the show, expect the first StreamBoost-based routers on the market in spring.

Pictures We Love: Best of 2012

Photograph by Mindy Schauer, Orange County Register/AP

Powder-splattered, and powder-splattering, runners cross the finish line of The Color Run 5K in Irvine, California, on April 22. Each kilometer (0.6 mile) of the event features a color-pelting station dedicated to a single hue, culminating in the Pollock-esque riot at kilometer 5.

The "magical color dust" is completely safe, organizers say, though they admit it's "surprisingly high in calories and leaves a chalky aftertaste."

Chelsea Clinton Raises Profile During Mom's Illness













While Hillary Clinton was in the hospital it was daughter Chelsea -- not the secretary of state or the former president Bill Clinton -- who spoke for the family.


She, along with the State Department, doled out what little information the family wanted to share in a series of tweets and when her mother was released from the hospital, it was Chelsea who delivered the thanks on behalf of her parents, tweeting her gratitude to the doctors as well as those who kept her mother in their thoughts while she recovered from a blood clot.


When Hillary Clinton leaves office, possibly at the end of this month, it will be the first time since 1982 that a Clinton will not be holding a public office.


The watch will be on whether Hillary Clinton makes another run for the White House in 2016, but almost inevitably people will also be watching to see if Chelsea Clinton decides to run for office, too.


"Americans always look for dynasties: Bush, Kennedy, Cuomo, Clinton … it's some kind of continuity. There will always be pressure on her to run for public office," said Hank Sheinkopf, a Democratic political strategist in New York.


"She's learning from the two best politicians in recent American history and she understands when to hold them and when to fold them," Sheinkopf said.


That sense of dynasty could also present a significant hurdle.

"She's got to A, demonstrate that she has the charisma of her father, or B, demonstrate that she has the policy chops of her mother. And I think like most people she is somewhere in between," a former Hillary Clinton aide from her 2008 campaign said. "People are judging her through each of her parents and it's an impossible standard."


Chelsea Clinton, 32, has inched towards a possible political career in recent statements and has become more politically active.


In an interview with Vogue published in August she was more open to it than she has been in the past, telling the magazine, "Before my mom's (presidential) campaign I would have said no," but "now I don't know."


"I believe that engaging in the political process is part of being a good person. And I certainly believe that part of helping to build a better world is ensuring that we have political leaders who are committed to that premise. So if there were to be a point where it was something I felt called to do and I didn't think there was someone who was sufficiently committed to building a healthier, more just, more equitable, more productive world? Then that would be a question I'd have to ask and answer."


Clinton also spoke of a change in her private to public life:


"Historically I deliberately tried to lead a private life in the public eye," she told the magazine. "And now I am trying to lead a purposefully public life."


Besides her work as a special correspondent with NBC, Chelsea Clinton has taken on high profile roles with her father's Clinton Global Initiative. She sits on several corporate boards and has both moderated and sat on panels discussing both women in politics and childhood obesity, among other issues.


She has also worked toward making same-sex marriage legal in New York last year, as well as gay marriage referendums in Maine, Maryland, Wisconsin and Washington state, all of which were successful in November. She has also been active in superstorm Sandy recovery, most notably delivering aid to the devastated Rockaways with her father.
