Stop Saying Privacy Is Dead - Member Feature Stories - Medium - 0 views

  •  
    "As privacy scholar Josh Fairfield says, while some dismiss privacy concerns by saying they have nothing to hide, we shouldn't accept that argument from anyone wearing clothes. Or anyone who closes the bathroom door, locks her home or car, or uses password-protected accounts. Or anyone who benefits from rules and norms that protect secrecy and confidentiality, prohibit government overreach, and give us recourse if others intrude upon our seclusion, publicly disclose embarrassing private facts, depict us in a false light, or appropriate our image or likeness.

Where everybody knows your face: Woody Harrelson photo used to spot thief | US news | T... - 0 views

  •  
    "Georgetown University's Center on Privacy and Technology highlighted the April 2017 episode in Garbage In, Garbage Out, a report on what it says are flawed practices in law enforcement's use of facial recognition. The report says security footage of the thief was too pixelated and produced no matches while high-quality images of Harrelson returned several possible matches and led to one arrest."

    "Hackers have attacked networks in a number of countries including data centres in Iran, where they left the image of a US flag on screens along with a warning: "Don't mess with our elections", the Iranian IT ministry said on Saturday. "The attack apparently affected 200,000 router switches across the world in a widespread attack, including 3,500 switches in our country," the Ministry of Communication and Information Technology said in a statement carried by Iran's official news agency IRNA"

Flat-pack heaven? Robots master task of assembling Ikea chair | Science | The Guardian - 0 views

  •  
    "In the meantime, Pham is keen to see if robots can learn to build the chair using only an image of the assembled product as a guide. Will the technology ever help humans who struggle with the task? "I don't think it is in Ikea's business model to have robots assemble their chairs," he said. "In the next 10 to 20 years, people will still be sweating over flat-pack furniture.""

Techniques for reliably fooling AI machine-vision classifiers / Boing Boing - 0 views

    "The Open AI researchers were intrigued by a claim that self-driving cars would be intrinsically hard to fool (tricking them into sudden braking maneuvers, say), because "they capture images from multiple scales, angles, perspectives, and the like.""

How funky tortoiseshell glasses can beat facial recognition | Technology | The Guardian - 1 views

  •  
    "Where the researchers struck gold was by realising that a large (but not overly large pair of glasses) could act to "change the pixels" even in a real photo. By picking a pair of "geek" frames, with relatively large rims, the researchers were able to obscure about 6.5% of the pixels in any given facial picture. Printing a pattern over those frames then had the effect of manipulating the image."

Scientists discover how the brain recognises faces - by reading monkey's minds | Scienc... - 0 views

  •  
    "Instead, the new work shows our brains rely on the kind of maths that an algorithm might use to perform the task. In fact, Tsao and her colleague, Steven Le Chang, stumbled on their discovery while working on computer vision. The pair had initially set themselves the challenge of coming up with a way of reliably converting facial images into a numerical representation."

Rosamund Pike is right to call out digital 'tweaks' ... but aren't we all at it? | Barb... - 0 views

  •  
    "It's fast getting to the point where it feels unreasonable to solely blame the famous and the industries that promote them. These days, people are going to plastic surgeons wanting to resemble their own modified avatars from selfies, rather than celebrities. If you like, the fiction of Hollywood perfection has been democratised. Indeed, it's interesting how, even as "improved" celebrities are mocked, or, as with Pike, call it out themselves, the modification of our own images continues unhindered, save for the occasional "#nofilter" humblebrag. It's gone beyond old-school catfishing (pretending to be someone else) to the point where people are essentially deep-faking themselves. And it's all just a bit of fun. Until it isn't. The desire to look better is all too human but are we inexorably moving towards the moment when we lose our grip on what we actually look like?"

Citizen: crime app falsely accused a homeless man of starting a wildfire | Technology |... - 0 views

  •  
    "But that was not before the falsely accused man had his name and image widely shared. The alert sent by Citizen contained a photo and was seen by more than 861,000 people. It read: "Citizen is offering a $30,000 reward to anyone who provides information that leads to the arrest of the arson suspect." Citizen told the Guardian in a statement it offered the cash reward "without formal coordination with the appropriate agencies". "Once we realized this error, we immediately retracted the photo and reward offer," it said. "We are actively working to improve our internal processes to ensure this does not occur again. This was a mistake we are taking very seriously.""

    "Rather than being "taught" medical knowledge, the AI was asked to learn using unsupervised deep neural networks, known as autoencoders, without being given any medical knowledge. The researchers developed a method for translating the features found by the AI-only numbers initially-into high-resolution images that can be understood by humans."

Parents Against Facial Recognition - 0 views

  •  
    "To Lawmakers and School Administrators: As parents and caregivers, there is nothing more important to us than our children's safety. That's why we're calling for an outright ban on the use of facial recognition in schools. We're concerned about this technology spreading to our schools, infringing on our kids' rights and putting them in danger. We don't even know the psychological impacts this constant surveillance can have on our children, but we do know that violating their basic rights will create an environment of mistrust and will make it hard for students to succeed and grow. The images collected by this technology will become a target for those wishing to harm our children, and could put them in physical danger or at risk of having their biometric information stolen or sold. The well-known bias built into this technology will put Black and brown children, girls, and gender noncomforming kids in specific danger. Facial recognition creates more harm than good and should not be used on the children we have been entrusted to protect. It should instead be immediately banned."

Humour over rumour? The world can learn a lot from Taiwan's approach to fake news | Arw... - 0 views

  •  
    "Inoculating people from misinformation and tackling the "infodemic" are key to fighting the coronavirus. Tang, Taiwan's first transgender government minister and a self-described "civic hacker", has done this by fostering digital democracy: using technology to encourage civic participation and build consensus. Tang has also quashed faked news by implementing a 2-2-2 "humour over rumour" strategy. A response to misinformation is provided within 20 minutes, in 200 words or fewer, alongside two fun images. Early in the pandemic, for example, people were panic-buying toilet paper because of a rumour that it was being used to manufacture face masks; supplies were running out. So, the Taiwanese premier, Su Tseng-chang, released a cartoon of him wiggling his bum, with a caption saying: "We only have one pair of buttocks." It sounds silly, but it went viral. Humour can be far more effective than serious fact-checking."
