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.

ECB to ring in New Year with rates on hold






FRANKFURT: The European Central Bank will usher in 2013 with steady interest rates at its first policy meeting this year to keep up the pressure on governments to solve the debt crisis, analysts predict.

With ECB interest rates currently at record lows and its latest anti-crisis weapon ready and primed for action, central bank chief Mario Draghi will not pass up the opportunity to insist once again that only governments can resolve the long-running crisis, economists said.

"Whilst a (rate) cut cannot be entirely ruled out, we do not expect the governing council to change interest rates at its meeting on Thursday," said Commerzbank economist Michael Schubert.

"On the one hand, ECB executive board members have tried to dampen rate cut speculation over recent weeks, and on the other, important sentiment indicators have increased once again," he said.

On Friday, the closely watched Purchasing Managers Index (PMI) for the entire euro area hit a nine-month high, offering hope the single currency area could be moving out of its deep double-dip recession.

Recent data for Germany, Europe's biggest economy, have also come in better than expected.

And German Finance Minister Wolfgang Schaeuble even went so far as to say he believed the embattled eurozone was now past the peak of its three-year-long debt crisis.

Market tensions have indeed eased since the ECB unveiled its anti-crisis bazooka in September, the so-called OMT bond-purchase programme.

The scheme is credited with marking a turning point in financial market sentiment towards the crisis-wracked euro even though it has not actually been used.

With markets now calmer, the ECB has been able to keep its gunpowder dry, keeping interest rates at their all-time low of 0.75 per cent and holding fire on other emergency anti-crisis measures as well, after pumping vast amounts of liquidity into the markets at the beginning of last year.

Nevertheless, at last month's meeting, ECB chief Draghi appeared to open the door to further rate cuts, crucially revealing that there had been "wide discussion" of such a move on the decision-making governing council and that the decision to keep rates on hold was anything but unanimous.

Commerzbank's Schubert pointed out, however, that top board members -- such as Yves Mersch, Peter Praet and Joerg Asmussen -- have all sought to play down possible rate cuts recently.

Deka Bank chief economist Ulrich Kater was similarly convinced that Draghi would not announce any monetary easing at his first press conference of the year.

"The policy of low interest rates is finally making itself felt in the periphery countries, thereby taking the pressure off the monetary policy actors to come up with new stimulus measures," he said.

"For the time being, there is no immediate need to act," he said.

In the United States, the US Federal Reserve hinted last week that its own huge programme of stimulus measures was under review and could be brought to an end sometime this year.

Capital Economics economist Jonathan Loynes cautioned, however, that "having prevented catastrophe in 2012 by pledging to do whatever it takes to save the euro, the ECB will have to follow words with actions in 2013".

While Loynes said he was expecting no policy changes to be announced on Thursday, "the pressure for action may soon be irresistible".

Postbank economist Thilo Heidrich said the likelihood of a rate cut was "wide open", but that he was betting on a further quarter-point reduction in the key refi rate to 0.5 per cent in the early months of this year and the ECB would keep it there "for some time to come".

Loynes at Capital Economics said that "despite the sizeable challenges facing the ECB (in 2013), it appears unlikely that it will take any steps towards meeting them at its meeting in January.

"No doubt Draghi will reaffirm that the ECB is ready to implement OMTs... and he may even show signs of warming to the idea of a cut in interest rates," Loynes said.

"Either way, though, he is likely to keep the onus on governments by stressing once again that the ECB cannot solve the region's debt crisis single-handedly," he concluded.

Windows laptop sales sink -- but that's just part of the problem



Will businesses and consumers spring for a Windows 8 hybrid priced at $849 that's powered by a relatively pokey Atom processor?

Will businesses and consumers spring for a Windows 8 hybrid priced at $849 that's powered by a relatively pokey Atom processor?

Windows 8 PC sales aren't trending well, according to a new report. And consumers' addiction to low cost may be a factor.


A blurb on Friday from the NPD Group said
Windows 8 holiday sales continue to not impress.


"The launch of Windows 8...did little to boost holiday sales or improve the yearlong Windows notebook sales decline," NPD said.


More specifically, Windows laptop "holiday unit sales" were down 11 percent year-to-year, the market researcher said.


Want more deets? The average selling price of a Windows laptop rose a hair -- $2 to $420, according to NPD.



Meanwhile, the average selling price of a MacBook rose almost $100 to $1,419 on a sales drop of 6 percent.


Upshot: Both Windows lappies and MacBooks saw sales decrease, but Apple made a $100 average selling price gain versus a couple of bucks for Windows.


Maybe a bigger part of the Windows sales problem is that the mix of systems has changed compared with the glory days of
Windows 7.


That is, Windows 7 was accompanied by a crush of ultracheap netbooks, according to an analysis at the Supersite for Windows -- which had some harsh words for netbooks.


"Many of those 20 million Windows 7 licenses each month -- too many, I think -- went to machines that are basically throwaway, plastic crap. Netbooks didn't just rejuvenate the market just as Windows 7 appeared, they also destroyed it from within," Paul Thurrott wrote.


"Now consumers expect to pay next to nothing for a Windows PC. Most of them simply refuse to pay for more expensive Windows PCs."


And, by the way, shipments of systems powered by Intel's power-efficient-yet-lower-performance Atom chip -- the same class of processors used in netbooks -- are barely a trickle at this point. And to make matters worse, some, like the $849
HP Envy x2, are priced way above the $399 netbooks of holiday seasons past.

There is a counterpoint to the NPD report, however. Analysts have told CNET that demand for touch-screen Windows 8 PCs in the U.S. is strong. Rhoda Alexander, an analyst at IHS iSuppli, told CNET last month that some vendors can't keep touch-screen PCs on the shelf.

So, if supply of touch-screen displays eases and system prices drop a bit, that could drive more sales. And prove to be an advantage over Apple, which doesn't have any touch-screen MacBooks.


At $749, Samsung's Intel Atom chip-based ATIV Smart PC is about $300 more than a Windows 7 Netbook.

Gun Show Near Newtown Goes on Despite Anger













A little more than 40 miles from Sandy Hook Elementary School, where last month 20 first graders and six staff members were massacred, gun dealers and collectors alike ignored calls to cancel a gun show, and gathered for business in Stamford, Conn.


Four other gun shows with an hour of Newtown, Conn., recently cancelled their events in the wake of the shootings, when 20-year-old Adam Lanza broke in to the elementary school with a semi-automatic assault rifle and three other guns.


The organizers in Stamford emphasized their show only displayed antique and collectible guns, not military style assault weapons like the one used by Lanza in Sandy Hook.


Still, Stamford Mayor Michael Pavia had called for the show to close its doors, calling it "insensitive" to hold so close to the murders.


Gun show participant Sandy Batchelor said he wasn't sure about whether going ahead with the show was "insensitive," but said the shooter should be blamed, not the weapons he used.


"I don't have a solid opinion on [whether it is insensitive]," Batchelor said. "I'm not for or against it. I would defend it by saying it wasnt the gun."


In nearby Waterbury, the community cancelled a show scheduled for this weekend.


"I felt that the timing of the gun show so close to that tragic event would be in bad taste," Waterbury Police Chief Chief Michael J. Gugliotti said.












National Rifle Association News Conference Interrupted by Protesters Watch Video





Gugliotti has halted permits for gun shows, saying he was concerned about firearms changing hands that might one day be used in a mass shooting.


Across the state line in White Plains, N.Y, Executive Rob Astorino also canceled a show, three years after ending a had that had been in place since the 1999 Columbine High School shooting in Colorado. He said he felt the show would be inappropriate now.


But across the country, farther away from Connecticut, attendance at gun shows is spiking, and some stores report they can hardly keep weapons on their shelves with some buyers fearful of that the federal government will soon increase restrictions on gun sales and possibly ban assault weapons altogether.


"We sold 50-some rifles in days," said Jonathan O'Connor, store manager of Gun Envy in Minnesota.


President Obama said after the Sandy Hook shooting that addressing gun violence would be one of his priorities and Rep. Nancy Pelosi, D-Calif., said she would introduce an assault weapons ban this month.


But it is not just traditional advocates of gun control that have said their need to be changes in gun laws since the horrific school shooting.


Republican Sen. Kay Bailey Hutchison of Texas and Virginia Sen. Mark Warner, a Democrat but a long-time opponent of gun control who like Hutchison has received an A rating from the NRA, have both come out in support of strengthening gun laws.


In Stamford, gun dealer Stuart English said participants at the gun show there are doing nothing wrong.


"I have to make a living. Life goes on," gun dealer Stuart English said.


ABC News asked English, what he thought about the mayor of Stamford calling the show "insensitive."


"He's wrong," English said. "This is a private thing he shouldn't be expressing his opinion on."

Graphic in-car crash warnings to slow speeding drivers



Paul Marks, chief technology correspondent

"You would die if you crashed right now." Would such a warning make you take your foot off the accelerator? That's the idea behind a scheme to warn drivers of the consequences of speeding developed by engineers at Japan's Fukuoka Institute of Technology and heavy goods vehicle maker UD Trucks, also in Japan. They are developing what they call a "safe driving promotion system" that warns drivers what kind of crash could ensue if they don't slow down.






Their patent-pending system uses the battery of radar, ultrasound sonar and laser sensors found in modern cars and trucks to work out the current kinetic energy of a vehicle. It also checks out the distance to the vehicle in front and keeps watch on its brake lights, too. An onboard app that has learned the driver's reaction time over all their previous trips then computes the likelihood of collision - and if the driver's speed is risky, it displays the scale of damage that could result.


The warning that flashes up could vary from something like a potential whiplash injury due to a rear-end shunt to a fatal, car-crushing collision with fire. The inventors hope this kind of in-car advice will promote safety more forcefully than current warning systems, which merely display the distance to the vehicle in front. "A sense of danger will be awakened in the driver that makes them voluntarily refrain from dangerous driving," they predict.

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.

Quadruple Amputee Gets Two New Hands on Life













It's the simplest thing, the grasp of one hand in another. But Lindsay Ess will never see it that way, because her hands once belonged to someone else.


Growing up in Texas and Virginia, Lindsay, 29, was always one of the pretty girls. She went to college, did some modeling and started building a career in fashion, with an eye on producing fashion shows.


Then she lost her hands and feet.


Watch the full show in a special edition of "Nightline," "To Hold Again," TONIGHT at 11:35 p.m. ET on ABC


When she was 24 years old, Lindsay had just graduated from Virginia Commonwealth University's well-regarded fashion program when she developed a blockage in her small intestine from Crohn's Disease. After having surgery to correct the problem, an infection took over and shut down her entire body. To save her life, doctors put her in a medically-induced coma. When she came out of the coma a month later, still in a haze, Lindsay said she knew something was wrong with her hands and feet.


"I would look down and I would see black, almost like a body that had decomposed," she said.


The infection had turned her extremities into dead tissue. Still sedated, Lindsay said she didn't realize what that meant at first.










"There was a period of time where they didn't tell me that they had to amputate, but somebody from the staff said, 'Oh honey, you know what they are going to do to your hands, right?' That's when I knew," she said.


After having her hands and feet amputated, Lindsay adapted. She learned how to drink from a cup, brush her teeth and even text on her cellphone with her arms, which were amputated just below the elbow.


"The most common questions I get are, 'How do you type,'" she said. "It's just like chicken-pecking."


PHOTOS: Lindsay Ess Gets New Hands


Despite her progress, Lindsay said she faced challenges being independent. Her mother, Judith Aronson, basically moved back into her daughter's life to provide basic care, including bathing, dressing and feeding. Having also lost her feet, Lindsay needed her mother to help put on her prosthetic legs.


"I've accepted the fact that my feet are gone, that's acceptable to me," Lindsay said. "My hands [are] not. It's still not. In my dreams I always have my hands."


Through her amputation recovery, Lindsay discovered a lot of things about herself, including that she felt better emotionally by not focusing on the life that was gone and how much she hated needing so much help but that she also truly depends on it.


"I'm such an independent person," she said. "But I'm also grateful that I have a mother like that, because what could I do?"


Lindsay said she found that her prosthetic arms were a struggle.


"These prosthetics are s---," she said. "I can't do anything with them. I can't do anything behind my head. They are heavy. They are made for men. They are claws, they are not feminine whatsoever."


For the next couple of years, Lindsay exercised diligently as part of the commitment she made to qualify for a hand transplant, which required her to be in shape. But the tough young woman now said she saw her body in a different way now.

Unique meteorite hints Mars stayed moist for longer








































A scorched rock bought in Morocco turned out to be a diamond in the rough. The unusual meteorite may be the first sample of the Red Planet's crust ever to hit Earth, and it suggests that Mars held on to its water for longer than we thought.












The meteorite, dubbed Northwest Africa (NWA) 7034, is strikingly different from the 111 previously discovered Martian meteorites. "You could look at meteorites for the rest of your life and not find another one like this," says Carl Agee of the University of New Mexico in Albuquerque, who was part of a team that has recently analysed NWA 7034. "This is in its own new group."













The most distinctive difference is its mineral content. Previously found meteorites had unearthly oxygen isotopes that marked them as being from another planet, and their volcanic origin made Mars the most likely culprit. But compared to these meteorites, surface rocks studied by Martian rovers and orbiters are much richer in light metals such as potassium and sodium. This suggests the known meteorites came from deeper inside the Red Planet.












"We're watching data coming back from Mars, and everything that comes back doesn't look like the Martian meteorites we have in our collections," says Munir Humayun of Florida State University in Tallahassee, who was not involved in the new study. "That's kind of a bummer."











By contrast, NWA 7034's chemistry closely resembles the rock and soil studied by NASA's Spirit rover. Preliminary measurements from the Curiosity rover, which landed in August 2012, suggest its landing site also has a similar composition.












Drying era













"Finally, it looks as if we have a sample that is very similar to the rocks that the rovers are seeing," Agee says. What's more, the Moroccan meteorite may come from a period in Mars' history when the planet was drying out.











Mars is thought to have once been much warmer, wetter and more hospitable to life. Then it morphed into the dry, cold desert we see today. The oldest known Mars meteorite, called the Allan Hills meteorite, is 4.5 billion years old. The other 110 meteorites are much younger – 1.5 billion years old at most – and formed after Mars is thought to have lost its water.













NWA 7034 is 2.1 billion years old, making it the first meteorite that may hail from the transitional era. Intriguingly, it has as much as 30 times more water than previous meteorites locked up in its minerals. "It opens our mind to the possibility that climate change on Mars was more gradual," Agee says. "Maybe it didn't lose its water early on."











Hot deal













The 319.8-gram rock found its way to Agee's lab via an amateur collector named Jay Piatek. He bought it for what turned out to be a knock-down price from a Moroccan meteorite dealer, who recognised its scorched exterior as a sign that it fell from space. "It didn't look like a Martian meteorite, so it didn't have the Martian meteorite value at the time," Agee says, adding that Mars rock can go for $500 to $1000 per gram.












Piatek brought the rock to Agee's lab to find out what it was. "Honestly, I had never seen anything like it. I was baffled, initially," Agee says. "Now, about a year and a half after the first time I set eyes on this thing, we are convinced that it is Martian, a new type, and has important implications for understanding the history of Mars."












Humayun says the results so far are exciting, and that the rock's carbon content could also yield valuable insights once other researchers get their hands on it.












"What's the most exciting thing you would want to do with a rock that comes from the near surface of Mars, especially one that seems to be loaded with water?" he asks. "I would say, what about life?" Agee and colleagues found organic matter in the meteorite, he says, but it will take more work to determine whether it was of Martian or terrestrial origin.












If it's Martian, "that would spark a lot of excitement", he says.
