Researchers Have Figured Out How To Fake News Video With AI
A team of computer scientists at the University of Washington have used artificial intelligence to render visually convincing videos of Barack Obama saying things he's said before, but in a totally new context. In a paper published this month, the researchers explained their methodology: Using a neural network trained on 17 hours of footage of the former U.S. president's weekly addresses, they were able to generate mouth shapes from arbitrary audio clips of Obama's voice. The shapes were then textured to photorealistic quality and overlaid onto Obama's face in a different "target" video. Finally, the researchers retimed the target video to move Obama's body naturally to the rhythm of the new audio track. In their paper, the researchers pointed to several practical applications of being able to generate high quality video from audio, including helping hearing-impaired people lip-read audio during a phone call or creating realistic digital characters in the film and gaming industries. But the more disturbing consequence of such a technology is its potential to proliferate video-based fake news. Though the researchers used only real audio for the study, they were able to skip and reorder Obama's sentences seamlessly and even use audio from an Obama impersonator to achieve near-perfect results. The rapid advancement of voice-synthesis software also provides easy, off-the-shelf solutions for compelling, falsified audio. |

What if Barack Obama established a Presidential Advisory Committee that would meet once every couple of months, bringing together the former presidents for a conference in order to seek their collective wisdom? There is a wealth of experience in former presidents that generally goes untapped. |

As a scholar, you don't want to repeat yourself, ever. You're supposed to say it once, publish it, and then it's published, and you don't say it again. If someone comes and gives a scholarly paper about something they've already published, that's just terrible. As a university president, you have to say the same thing over and over and over. |

Crime shapes how we think about the world; it shapes social decisions that we make; it shapes our base of knowledge. But we don't talk about it intelligently. |

The Web is actually a coming together of three technologies, if you like: the hypertext, the personal computer, and the network. So, the network we had, and the personal computers were there, but people didn't use them, because they didn't know what to use them for, except maybe for a few games. |

Before the advent of artificial light, we had 13, 14 hours in bed every night... and so what we experience now is about a 40% contraction of how we used to sleep, and I for one am glad of that - I don't want to spend 13 hours in bed. |

The key thing is, even if you only have a couple of hours a month, those two hours shoulder-to-shoulder, next to one student, concentrated attention, shining this beam of light on their work, on their thoughts and their self-expression, is going to be absolutely transformative, because so many of the students have not had that ever before. |

We know that Europe loves President Obama. He had adoring crowds. The press loves Obama. The question is how will this date end? Okay? The question is, to what end? Why do they love President Obama? They love his personal story, they love his wife. North Korea, China and Russia don't really care about Michelle's arms and, you know, whether they gave an iPod to the Queen, okay? |

A complete investment in the Obama administration required that any real opposition had to be demonized. The investment in Barack Obama had to be protected. |

President Barack Obama has it right - there is a lot to change about Washington. The problem is, not much will get changed unless we confront the runaway filibuster in the U.S. Senate. |

And while I stood there I saw more than I can tell and I understood more than I saw; for I was seeing in a sacred manner the shapes of all things in the spirit, and the shape of all shapes as they must live together like one being. |

Scientists Train AI To Learn People's Voices, Then Generate Their Faces
An neural network named "Speech2Face" was trained by scientists on millions of educational videos from the internet that showed over 100,000 different people talking. From this dataset, Speech2Face learned associations between vocal cues and certain physical features in a human face, researchers wrote in a new study. The AI then used an audio clip to model a photorealistic face matching the voice, and the results are surprisingly close to the actual faces of the people whose voices it listened to. The faces generated by Speech2Face didn't precisely match the people behind the voices. But the images did usually capture the correct age ranges, ethnicities and genders of the individuals, according to the study.

Scientists Create DNA-Based Exploit of a Computer System
Archeron an hour ago 18
Archeron writes: It seems that scientists at University of Washington in Seattle have managed to encode malware into genomic data, allowing them to gain full access to a computer being used to analyze the data. While this may be a highly contrived attack scenario, it does ask the question whether we pay sufficient attention to data-driven exploits, especially where the data is instrument-derived. What other systems could be vulnerable to a tampered raw data source? Perhaps audio and RF analysis systems? MIT Technology Review reports: "To carry out the hack, researchers led by Tadayoshi Kohno and Luis Ceze encoded malicious software in a short stretch of DNA they purchased online. They then used it to gain 'fu...

MIT's AI Uses Radio Signals To See People Through Walls
Researchers at the Massachusetts Institute of Technology have developed a new piece of software that uses wifi signals to monitor the movements, breathing, and heartbeats of humans on the other side of walls. While the researchers say this new tech could be used in areas like remote healthcare, it could in theory be used in more dystopian applications. Inverse reports:
"We actually are tracking 14 different joints on the body [...] the head, the neck, the shoulders, the elbows, the wrists, the hips, the knees, and the feet," Dina Katabi, an electrical engineering and computer science teacher at MIT, said. "So you can get the full sti...

Hundreds of Researchers From Harvard, Yale and Stanford Were Published in Fake Academic Journals
In the so-called "post-truth era," science seems like one of the last bastions of objective knowledge, but what if science itself were to succumb to fake news? From a report:
Over the past year, German journalist Svea Eckert and a small team of journalists went undercover to investigate a massive underground network of fake science journals and conferences. In the course of the investigation, which was chronicled in the documentary "Inside the Fake Science Factory," the team analyzed over 175,000 articles published in predatory journals and found hundreds of papers from academics at leading in...

Engineers Say They've Created Way To Detect Weapons Using Wi-Fi
The researchers, which include engineers from Rutgers University-New Brunswick, Indiana University-Purdue University Indianapolis (IUPUI), and Binghamton University, published a study this month detailing a method in which common wifi can be used to easily and efficiently identify weapons, bombs, and explosive chemicals in public spaces that don't typically have affordable screening options. The researchers' system uses channel state information (CSI) from run-of-the-mill wifi. It can first identify whether there are dangerous objects in baggage without having to physically rifle through it. It then determines what the material is and what the risk level is. The researchers tested the detection system using 15 different obje...

Researchers Demonstrate Teleportation Using On-Demand Photons From Quantum Dots
A team of researchers from Austria, Italy and Sweden has successfully demonstrated teleportation using on-demand photons from quantum dots. In their paper published in the journal Science Advances, the group explains how they accomplished this feat and how it applies to future quantum communications networks. Scientists and many others are very interested in developing truly quantum communications networks -- it is believed that such networks will be safe from hacking or eavesdropping due to their very nature. But, as the researchers with this new effort point out, there are still some problems standing in the way. One of these is the difficulty in amplifying quantum signals. One way to get around this probl...

oogle's Voice-Generating AI Is Now Indistinguishable From Humans
Anonymous Coward 6 hours ago 75
An anonymous reader quotes a report from Quartz: A research paper published by Google this month -- which has not been peer reviewed -- details a text-to-speech system called Tacotron 2, which claims near-human accuracy at imitating audio of a person speaking from text. The system is Google's second official generation of the technology, which consists of two deep neural networks. The first network translates the text into a spectrogram (pdf), a visual way to represent audio frequencies over time. That spectrogram is then fed into WaveNet, a system from Alphabet's AI research lab DeepMind, which reads the chart and generates the corresponding audio elements accordingly. The Google researchers ...
