A group of researchers from the Institute of Telecommunications of the Warsaw University of Technology have devised a way to send and receive messages hidden in the data packets used to represent silences during a Skype call.
Wojciech Mazurczyk, Krysztof Szczypiorski and Maciej Karaœ have long been interested in steganography – the science of writing and transmitting secret messages within regular messages.
After learning that Skype transmits voice data in 130-byte packets and the silences in 70-byte packets, they came upon the idea of using the latter to conceal the sending and receiving of additional messages, Trusted Third Party reports (via Google Translate).
In order to do that, they created SkypeHide (or SkyDe), a piece of software that hijacks some of the “silence” packets and then embeds the encrypted messages into them. On the receiving computer, the same software extracts it and decrypts it.
The hidden messages can consist of text, audio or video, and can be transmitted at a rate of almost 1 kilobit per second. And, according to Mazurczyk, the secret data is indistinguishable from silence-period traffic.
More details about the software and how it works will be soon shared with the public, as the researchers are set to present the research at the 1st ACM Workshop on Information Hiding and Multimedia Security which is to be held in Montpellier, France, in June.

New surveillance laws being proposed in countries from the United States to Australia would force makers of online chat software to build in backdoors for wiretapping. For years, the popular video chat service Skype has resisted taking part in online surveillance—but that may have changed. And if it has, Skype’s not telling.
Historically, Skype has been a major barrier to law enforcement agencies. Using strong encryption and complex peer-to-peer network connections, Skype was considered by most to be virtually impossible to intercept. Police forces in Germany complained in 2007 that they couldn’t spy on Skype calls and even hired a company to develop covert Trojans to record suspects’ chats. At around the same time, Skype happily went on record saying that it could not conduct wiretaps because of its “peer-to-peer architecture and encryption techniques”.
Recently, however, hackers alleged that Skype made a change to its architecture this spring that could possibly make it easier to enable “lawful interception” of calls. Skype rejected the charge in a comment issued to the website Extremetech, saying the restructure was an upgrade and had nothing to do with surveillance. But when I repeatedly questioned the company on Wednesday whether it could currently facilitate wiretap requests, a clear answer was not forthcoming. Citing “company policy”, Skype PR man Chaim Haas wouldn’t confirm or deny, telling me only that the chat service “co-operates with law enforcement agencies as much as is legally and technically possible”.

Since the 1900′s the vast majority of the American population has dreamed about saying “NO” to the Unconstitutional, corrupt, Rothschild/Rockefeller banking criminals, but no one has dared to do so. Why? If just half of our Nation, and the “1%”, who pay the majority of the taxes, just said NO MORE! Our Gov’t would literally change over night. Why is it so hard, for some people to understand, that by simply NOT giving your money, to large Corporations, who then send jobs, Intellectual Property, etc. offshore and promote anti-Constitutional rights… You will accomplish more, than if you used violence. In other words… RESEARCH WHERE YOU ARE SENDING EVERY SINGLE PENNY!!! Is that so hard? The truth of the matter is… No one, except the Icelanders, have to been the only culture on the planet to carry out this successfully. Not only have they been successful, at overthrowing the corrupt Gov’t, they’ve drafted a Constitution, that will stop this from happening ever again. That’s not the best part… The best part, is that they have arrested ALL Rothschild/Rockefeller banking puppets, responsible for the Country’s economic Chaos and meltdown.
Last week 9 people were arrested in London and Reykjavik for their possible responsibility for Iceland’s financial collapse in 2008, a deep crisis which developed into an unprecedented public reaction that is changing the country’s direction.
It has been a revolution without weapons in Iceland, the country that hosts the world’s oldest democracy (since 930), and whose citizens have managed to effect change by going on demonstrations and banging pots and pans. Why have the rest of the Western countries not even heard about it? Continue reading
Here comes a chip that can pinpoint you in-door and out, it can even tell others on which floor of a building you are located. It’s the Broadcom 4752 chip. It takes signals from global navigation satellites, cell phone towers, and Wi-Fi hot spots, coupled with input from gyroscopes, accelerometers, step counters, and altimeters The company calls abilities like this ‘ubiquitous navigation,’ and the idea is that it will enable a new kind of e-commerce predicated on the fact that shopkeepers will know the moment you walk by their front door, or when you are looking at a particular product, and can offer you coupons at that instant.
Our cars run millions of lines of code that need constant and, often, critical updates. Jim Motavalli writes that Mercedes-Benz’s new mbrace2 ‘cloud infotainment system’ has a secret capability: it can update software automatically and wirelessly. In a process called ‘reflashing,’ the Mercedes system turns on the car operating system (CU), downloads the new application, then cuts itself off. With companies like Fisker paying dearly for constant recalls for software problems, automakers will likely rush to embrace this technology. No more USBs in the dashboard!
The Utah Department of Health has been hacked. 181,604 Medicaid and CHIP recipients have had their personal information stolen. 25,096 had their Social Security numbers compromised. The agency is cooperating with law enforcement in a criminal investigation. The hackers, who are believed to be located in Eastern Europe, breached the server in question on March 30, 2012.
Why would someone spend all of 2009 and 2010 turning off three strategically located commercial servers, each with its own DNS, that hosted more than 100 domains, each one of which had its own dedicated IP address, and consistently serving thousands of web pages day after day since 1997? Why would someone host their WordPress blog on their computer/server at home? Why would someone go offline for all of 2011? Why would someone participate in building a peer-2-peer search engine? Four questions, I’ll let you have four educated guesses and you can pick the question you want to answer and you don’t even have to submit the first two guesses. Never assume anything, doing so could make you and possibly someone you know look like a damn corporate media whore.
Democracy is just another word . . . . . . for nothing left to lose!
A New York-based designer has created a camouflage technique that makes it much harder for computer based facial recognition. Along with the growth of closed circuit television (CCTV) , this has become quite a concern for many around the world, especially in the UK where being on camera is simply a part of city life. Being recognized automatically by computer is something that hearkens back to 1984 or A Scanner Darkly. As we move further into the 21st century, this futuristic techno-horror fiction is seeming more and more accurate. Never fear though people, CV Dazzle has some styling and makeup ideas that will make you invisible to facial recognition cameras. Why the ‘fabulous’ name? It comes from World War I warship paint that used stark geometric patterning to help break up the obvious outline of the vessel. Apparently it all began as a thesis at the Interactive Telecommunications Program at New York University. It addressed the problems with traditional techniques of hiding the face, like masks and sunglasses and looked into more socially and legally acceptable ways of styling that could prevent a computer from recognizing your face. Fans of Assassin’s Creed might feel a bit at home with this, as it’s all about hiding in plain sight.

Millions of Americans arrested for but not convicted of crimes will likely have their DNA forcibly extracted and added to a national database, according to a bill approved by the US House of Representatives on Tuesday. By a 357 to 32 vote, the House approved legislation that will pay state governments to require DNA samples, which could mean drawing blood with a needle, from adults ‘arrested for’ certain serious crimes. Not one Democrat voted against the database measure, which would hand out about $75 million to states that agree to make such testing mandatory. … But civil libertarians say DNA samples should be required only from people who have been convicted of crimes, and argue that if there is probable cause to believe that someone is involved in a crime, a judge can sign a warrant allowing a blood sample or cheek swab to be forcibly extracted.
The NY Times reports that a new breed of coupon, printed from the Internet or sent to mobile phones, looks standard, but their bar codes can be loaded with a startling amount of data, including identification about the customer, Internet address, Facebook page information, and even the search terms the customer used to find the coupon in the first place. The coupons can, in some cases, be tracked not just to an anonymous shopper but to an identifiable person: a retailer could know that Amy Smith printed a 15-percent-off coupon after searching for appliance discounts at Ebates.com on Friday at 1:30 pm and redeemed it later that afternoon at the store. Using coupons also lets the retailers get around Google hurdles. Google allows its search advertisers to see reports on which keywords are working well as a whole but not on how each person is responding to each slogan. That alarms some privacy advocates. Companies can ‘offer you, perhaps, less desirable products than they offer me, or offer you the same product as they offer me but at a higher price,’ said Ed Mierzwinski, consumer program director for the United States Public Interest Research Group, which has asked the Federal Trade Commission for tighter rules on online advertising. ‘There really have been no rules set up for this ecosystem.’

(CNSNews.com) – Anyone who posts comments on the White House’s Facebook, MySpace, YouTube and Twitter pages will have their statements captured and permanently archived by the federal government, according to a plan that the White House is now seeking a contractor to carry out.
The Executive Office of the President is looking for a private contractor to capture and archive comments and information posted on social networking and new media sites where the White House has established a presence. While the Presidential Records Act (PRA) generally requires that the administration preserve information generated by the president and his staff, the White House says that in seeking to collect and preserve comments made by common citizens on social networking sites it is acting “out of an abundance of caution” to comply with the law.
In mid-August, the White House put out a “request for quotation” (RFQ)which seeks bids from private firms for the project. Under the terms stated by the White House, the contractor would have broad responsibilities in collecting information from White House related Web pages.
The RFQ for bids says the contractor is to “capture, store, [and] extract” information that will be transferred to the National Archives and Records Administration (NARA) for permanent storage. According to the White House proposal, the information involved will include the “capture of comments and publicly visible tags posted by users” on publicly accessible Web sites where the White House has established a presence.
