A new congressional bill could limit facial recognition technology - Vox - 0 views

  •  
    "In just the past few months, three cities - San Francisco, Oakland, and Somerville, Massachusetts - have passed laws to ban government use of the controversial technology, which analyzes pictures or live video of human faces in order to identify them. Cambridge, Massachusetts, is also moving toward a government ban. Congress recently held two oversight hearings on the topic and there are at least four pieces of current federal legislation to limit the technology in some way. "

The Citizen crime app hasn't made me safer - just more scared | Emma Brockes | Opinion ... - 0 views

  •  
    "Citizen, which was launched in 2017, is a glorified police scanner that promises to help users "stay safe and informed". It invites input from witnesses - mostly involving shaky phone footage of police milling around while a stretcher is carted by in the background - and, bafflingly, includes a comments section, in which users speculate fatuously on the crime in question and quibble over the accuracy of the map function. It is grimly fascinating, mildly addictive and, relative to its stated aims, totally without value."

Why Printers Add Secret Tracking Dots - 0 views

  •  
    "At that point, experts began taking a closer look at the document, now publicly available on the web. They discovered something else of interest: yellow dots in a roughly rectangular pattern repeated throughout the page. They were barely visible to the naked eye, but formed a coded design. After some quick analysis, they seemed to reveal the exact date and time that the pages in question were printed: 06:20 on 9 May, 2017 - at least, this is likely to be the time on the printer's internal clock at that moment. The dots also encode a serial number for the printer. "

    "Hultquist noted that cyberwarfare evens the battlefield between Iran and the US. "That's why they choose an asymmetric battleground," he said. "We might have this massive advantage with a very sophisticated ability, but we also have this very sophisticated society that makes us very vulnerable to computer attacks.""

    "When they opened their eyes, they did indeed see that the Digital Nation had been born. Only it hadn't set them free. They were being ruled by it. It hadn't tamed politics. It sent them berserk. And it hadn't brought people closer together. It had alienated them."

  •  
    "An artificial intelligence program has been developed that is better at spotting breast cancer in mammograms than expert radiologists.

The smartphone tracking industry has been rumbled. When will we act? | John Naughton | ... - 0 views

  •  
    "This is the so-called "privacy paradox", and the question is, what is needed to trigger an appropriate shift in regulation and public behaviour.

    "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."

Silicon Valley's Secret Philosophers Should Share Their Work | WIRED - 0 views

    "Marx had a point. Especially when it comes to ethics, philosophy is often better at finding complications and problems than proposing changes. Silicon Valley has been better at changing the world (even if through breaking things) than taking pause to think through the conse­quences."
