Congress investigating deepfakes after doctored Pelosi video report says

first_img Legal Facebook Donald Trump Deepfake coverage on CNET Deepfakes may ruin the world. And they can come for you, too Samsung deepfake AI could fabricate a video of you from a single profile pic Tags A manipulated clip of House Speaker Nancy Pelosi has people worried about bogus videos in the run-up to 2020. Larry French/Getty Images Congress is looking to investigate deepfakes after the appearance of doctored videos of House Speaker Nancy Pelosi, says a Tuesday report from CNN. Deepfakes, video forgeries that make people appear to be doing or saying things they didn’t, are the moving-picture equivalent of bogus images created with programs like Photoshop. Deepfake software has made manipulated videos accessible and increasingly harder to detect as fake. One technique enables users to make a deepfake using a single image, such as the Mona Lisa.Speaking with CNN, House Intelligence Committee Chair Adam Schiff, a Democrat from California, reportedly said the Russian fake news campaign during the 2016 presidential election could escalate for the 2020 presidential race thanks to deepfakes. “The most severe escalation might be the introduction of a deepfake — a video of one of the candidates saying something they never said,” Schiff said. Schiff called the Pelosi video a “cheap fake.””Very easy to make, very simple to make, real content just doctored,” Schiff reportedly told the publication. “If you look back at how impactful the Mitt Romney videotape about the 47% was, you could imagine how a videotape that is more incendiary could be election-altering. “Combine that with the fact that we already have a president of the United States who says the things that are real, like the Access Hollywood tape, are fake, and things that are fake, like the Pelosi tape — he pushes out as real.” 1center_img Politics Security Culture Digital Media Online Share your voice On May 23, videos doctored to make Pelosi appear like she was drunkenly slurring her words spread across Facebook. Facebook refused to take down the viral clip, despite reportedly having been looking into its manipulated-media policy just days before the video appeared. The Pelosi videos then disappeared from Facebook on Monday, but the social network denied removing them. In her speech, originally made at a Center for American Progress event, Pelosi accused Trump of being part of a “cover-up.” The video was then found by the The Washington Post to have been slowed to around 75% of its original speed, with the pitch of Pelosi’s voice also altered. The doctored videos went viral after being posted to Facebook, Twitter and YouTube, with one version on Facebook being viewed over 1.4 million times and shared 30,000 times. Pelosi, another Democrat from California, slammed the social network. “We have said all along, poor Facebook, they were unwittingly exploited by the Russians,” Pelosi told KQED News on Wednesday. “I think wittingly, because right now they are putting up something that they know is false. I think it’s wrong.” “[Facebook is] lying to the public … I think they have proven — by not taking down something they know is false — that they were willing enablers of the Russian interference in our election,” she said. Schiff’s office didn’t immediately respond to a request for comment. Commentlast_img read more

Apple Music Is Coming to Amazon Echo Speakers

0 Comment

first_imgAmazon has teamed up with Apple to bring Apple Music to its Echo line of smart speakers. Echo owners will be able to access Apple Music on their devices starting December 17, Amazon announced Friday.The integration will allow users to ask for songs, artists and albums with voice commands. Apple Music is also bringing playlists as well as custom radio stations, including Beats1, to Echo speakers.“Music is one of the most popular features on Alexa—since we launched Alexa four years ago, customers are listening to more music in their homes than ever before,” said Amazon devices senior vice president Dave Limp in a statement. “We’re thrilled to bring Apple Music – one of the most popular music services in the US – to Echo customers this holiday.”Amazon Echo speakers have already had access to Spotify and Pandora as well as Amazon Music. The company has also been increasingly courting music fans with better-sounding hardware: The first Echo speaker was still very much optimized for news, podcasts and voice interaction, but more recently, Amazon introduced a dedicated Echo Sub as well as gear for audiophiles to connect their own high-end speaker systems to Amazon’s Alexa assistant. ×Actors Reveal Their Favorite Disney PrincessesSeveral actors, like Daisy Ridley, Awkwafina, Jeff Goldblum and Gina Rodriguez, reveal their favorite Disney princesses.

This material may not be published, broadcast, rewritten or redistributed in whole or part without the express written permission of PhysOrg.com. In their study, Pradip Ghosh of the Nagoya Institute of Technology and his coauthors have demonstrated how to fabricate CNCSs on a transparent, flexible substrate at room temperature. The resulting CNCS-based electron emitter could then be used as a field electron emission (FEE) source for transparent, flexible field emission displays (FEDs). FEDs are a new kind of flat panel display that have several advantages, such as high contrast and lower power consumption than liquid crystal displays (LCDs). However, making FEDs transparent is very difficult since field electron emission requires a very high electric field and operation voltage. In order to achieve this high voltage, researchers usually use surfaces with a rugged sharp tip structure since the electric field is enhanced around the tip regions, enabling the operation voltage to be dramatically reduced. For this reason, as coauthor Masaki Tanemura from the Nagoya Institute of Technology explained, rugged surface structure is usually necessary for practical field electron emission sources, but so far ruggedness has not allowed for transparency.“Imagine sand-blasted glasses,” Tanemura told PhysOrg.com. “Glasses are transparent, but sand-blasted glasses are not due to the light scattering by the rugged surface structure. Similar to this example, transparency has not been possible for FEE sources.”By fabricating CNCSs that are smaller than the wavelength of visible light, the researchers found that they could overcome this challenge to produce fully transparent and flexible field electron emitters.“CNCSs have given transparency and flexibility to FEE sources for the first time,” Tanemura said. “To get CNCS-based transparent materials, it is highly desirable to control the diameter and length of the CNCSs. We have successfully controlled the diameter and length of the CNCSs below the wavelength of visible light at room temperature using an ion irradiation method. A careful scanning electron microscopy (SEM) inspection revealed that the diameter and length of most of the CNCSs were lower than the wavelength of the visible light. Thus this unique structure of the CNCSs was very useful to fabricate a CNCS-based transparent and flexible field electron emitter.” More information: Pradip Ghosh, M. Zamri Yusop, Syunsaku Satoh, Munisamy Subramanian, Akari Hayashi, Yasuhiko Hayashi, and Masaki Tanemura. “Transparent and Flexible Field Electron Emitters Based on the Conical Nanocarbon Structures.” J. Am. Chem. Soc. Doi:10.1021/ja909346e Explore furthercenter_img (PhysOrg.com) — During the past several years, researchers have used carbon nanotubes and nanofibers to fabricate a variety of transparent, flexible devices, such as OLEDs, transistors, and solar cells. But the development of transparent and flexible field electron emitters made of these nanomaterials still remains a challenge. In a new study, a team of researchers from Japan and Malaysia has shown that the key to the challenge may lie in the unique geometry of conical nanocarbon structures (CNCSs). In their experiments, the scientists bombarded a nafion substrate with argon ions for 30 seconds at room temperature. The irradiation produced uniformly distributed CNCSs over the entire nafion surface. The scientists measured that individual CNCSs had a base diameter of about 200 nanometers and a length/height of a few hundred nanometers, which is smaller than the wavelength of visible light. Overall, the material’s emission characteristics (its turn-on and threshold fields) were comparable to previous opaque electron emitters.As the researchers explain, the new method of using CNCSs for constructing transparent and flexible field electron emitters has several advantages. The method is simple in that it can be performed at room temperature, doesn’t require a catalyst, and doesn’t risk damaging the substrate. The scientists attribute these advantages to the unique conical geometry of the CNCSs. As a next step, the scientists plan to fabricate a transparent, flexible phosphor material, which is necessary for observing visible light emission and for the future construction of complete FEDs. The researchers predict that the technique could lead to transparent, flexible FEDs that are lightweight and inexpensive.“FED is a kind of flat panel display,” Tanemura explained. “Compared with other types of flat panel displays such as LCDs and electroluminescence displays, FED is advantageous in its brightness and size (a huge size is possible).” He added that transparent, flexible FEDs have great potential for applications including so-called head-up displays and highly intelligent information displays used in the coming ubiquitous world, when computers become thoroughly integrated into our everyday activities. “For example, head-up displays will be used on a curved front glass of vehicles (airplanes, trains, cars, and so on), full-face helmets, spectacles, and so on,” he said. “Usually it is transparent, but various kinds of information, such as maps, customer information, alarms, and security, will be displayed on demand. In the ubiquitous world, displays should be foldable (rollable) and light for mobility. You can enjoy TV, movies, games, communication, and obtain various kinds of information using an unfolded wide screen. Transparent and flexible FEDs make it realistic!” Citation: Conical nanocarbon structures could lead to flexible, transparent field emission displays (2010, March 25) retrieved 18 August 2019 from https://phys.org/news/2010-03-conical-nanocarbon-flexible-transparent-field.html This SEM image shows conical nanocarbon structures (CNCSs) fabricated on a transparent and flexible nafion substrate. Because the CNCSs are smaller than the wavelength of visible light, they have given transparency and flexibility to field electron emission sources for the first time.

Are MotionBased Gaming Technologies Right for Your Business

0 Comment

first_img Register Now » Q: I hear companies are hacking motion-based gaming technologies for new applications. How do I get in? A: It’s true — gaming consoles have launched an industry that has nothing to do with play. The technologies at the heart of Nintendo’s Wii U, Microsoft’s Kinect for Xbox 360 and Sony’s SOEmote are making motion capture (mocap), gesture recognition and facial rendering easy and cheap enough for entrepreneurs to hack and turn into wholly new businesses.Toronto-based GestSure Technologies, for example, uses a Microsoft Kinect module to create touch-free medical operating room tools. And Los Angeles-based Styku uses the Kinect module to scan consumers’ bodies and create a remote virtual fitting room where customers can “try on” clothes before making an online purchase. Nice fit, indeed.To get the complete story on how low-cost mocap has sparked a startup blitz, we sat down with Marty Smets, an ergonomics simulation engineer at Ford Motor Company in Dearborn, Mich.How does your company use MoCap? At a car company like Ford, motion-sensing technologies are an integral part of the design and manufacturing process. It helps us anticipate things like how drivers will see speedometers. And it flags us on how workers must move to build cars safely. The process shaves something like eight to 14 months off a four-year vehicle-development time. That is major money.How did this enterprise-level tech become a small-business opportunity?Business-grade motion tracking was once strictly the stuff of $250,000 camera systems and pricey processing software found in special effects films like Avatar or at Ford. No more. The $150 Xbox Kinect uses a low-cost depth sensor and camera to “see” in three dimensions. When the Kinect and the Wii came online, developers began messing with them, creating hacks en masse and giving rise to sites such as KinectHacks.net. Soon the web was flooded with new mocap ideas.It can’t be that simple for a small biz to get into.Actually it is. Microsoft recently released a formal, supported developer’s kit for the Kinect. For about $250 anybody can buy the software and tools needed to build robust mocap services. All that’s needed is the ability to program in basic computer languages–talent that can be found at any local college or technical school. To help advance the technology [startup accelerator] TechStars even launched a startup incubator specifically for Kinect-based ideas.How does this market work? Fortunately the game console manufacturers are taking their cues from Apple’s success with courting small developers through the App Store. Apple provided the tool and then opened it up to app-makers and asked, “How clever are you?” And as we’ve seen, the sky’s the limit in terms of imagination and potential moneymaking ideas. 3 min read Growing a business sometimes requires thinking outside the box.

ENGLAND Knights coach Keiron Purtill has made six

0 Comment

first_imgENGLAND Knights coach Keiron Purtill has made six changes to the squad that defeated France last week for tomorrow’s clash against Cumbria at Whitehaven’s Recreation Ground (3.00pm).The Knights won their first ever fixture last Saturday in some style, defeating France 38-18, but Purtill has resisted the temptation to stick with a winning team.“We’ve made a few changes to the squad to face Cumbria and brought in a few fresh bodies,” said Purtill. “We know Cumbria will be coming out to give us a tough game and we want to be firing on all cylinders.“Cumbrians are very passionate about Rugby League and when we visited a few local schools in the area today it was clear to see just how much the people of the area enjoy the sport.“We’re just as passionate about representing England and we want to create a legacy as the first ever Knights team and win every game we play in. Playing for your country is the highest honour you can achieve and these guys all want to stake their claim for a place in the senior side so they’ll be going out ready to match whatever comes at them.“We had a good win against France and it’s always good to get that first victory under your belt but we won’t be resting on our laurels.“Steve McNamara has told these players that there is a chance for Four Nations representation if anyone in the senior squad gets injured or withdraws so it means a lot to everyone involved. We’ll be cheering on the lads in Avignon tonight but we’re fully focused on the game to come tomorrow as well.”After steering the side to victory over France, Hull FC’s Joe Westerman has retained the captain’s role and he is joined in the starting 13 by St Helens duo Scott Moore and Paul Clough, Leeds Rhinos players Zak Hardaker and Chris Clarkson along with Warrington’s Chris Riley and Harlequins player Luke Gale.England Knights 17-Man Squad to face Cumbria1, Chris Riley (Warrington Wolves, Woolston Rovers)2, Josh Charnley (Wigan Warriors, Wigan St Pats)3, Zak Hardaker (Leeds Rhinos, Featherstone Lions)4, Kris Welham (Hull KR, Myton Warriors)5, Jodie Broughton (Salford City Reds, Queens)6, Richie Myler (Warrington Wolves, Halton West Bank)7, Luke Gale (Harlequins RL, Middleton Marauders)8, Lee Mossop (Wigan Warriors, Hensingham)9, Scott Moore (St Helens, Blackbrook)10, Paul Clough (St Helens, Blackbrook)11, Chris Clarkson (Leeds Rhinos, East Leeds)12, Joe Westerman (C) (Hull FC, Featherstone Lions)13, Liam Farrell (Wigan Warriors, Wigan St Pats)14, Liam Watts (Hull KR, Featherstone Lions)15, Matty Smith (Salford City Reds, Blackbrook)16, James Donaldson (Bradford Bulls, Wath Brow Hornets)17, Joe Arundel (Castleford Tigers, Castleford Panthers)last_img read more
