Windows Hello Face Unlock No Longer Works in the Dark and Microsoft Says It's Not a Bug

1 month 1 week ago
Microsoft has disabled Windows Hello's ability to authenticate users in low-light environments through a recent security update that now requires both infrared sensors and color cameras to verify faces. The change forces the system to see a visible face through the webcam before completing authentication with IR sensors. Windows Hello earlier relied solely on infrared sensors to create 3D facial scans, allowing the feature to work in complete darkness similar to iPhone's Face ID. Microsoft pushed the dual-camera requirement to address a spoofing vulnerability in the biometric system.

Japan Builds Near $700 Million Fund To Lure Foreign Academic Talent

1 month 1 week ago
An anonymous reader shares a report: Japan is the latest nation hoping to tempt disgruntled US researchers alarmed by the Trump administration's hostile attitude to academia to relocate to the Land of the Rising Sun. The Japanese government aims to create an elite research environment, and has detailed a $693 million package to attract researchers from abroad, including those from America who may have seen their budgets slashed or who fear a clampdown on their academic freedom.

Researchers Create World's First Completely Verifiable Random Number Generator

1 month 1 week ago
Researchers have built a breakthrough random number generator that solves a critical problem: for the first time, every step of creating random numbers can be independently verified and audited, with quantum physics guaranteeing the numbers were truly unpredictable. Random numbers are essential for everything from online banking encryption to fair lottery drawings, but current systems have serious limitations. Computer-based generators follow predictable algorithms -- if someone discovers the starting conditions, they can predict all future outputs. Hardware generators that measure physical processes like electronic noise can't prove their randomness wasn't somehow predetermined or tampered with. The new system, developed by teams at the University of Colorado Boulder and the National Institute of Standards and Technology, uses quantum entanglement -- Einstein's "spooky action at a distance" -- to guarantee unpredictability. The setup creates pairs of photons that share quantum properties, then sends them to measurement stations 110 meters apart. When researchers measure each photon's properties, quantum mechanics ensures the results are fundamentally random and cannot be influenced by any classical communication between the stations. The team created a system called "Twine" that distributes the random number generation process across multiple independent parties, with each step recorded in tamper-proof digital ledgers called hash chains. This means no single organization controls the entire process, and anyone can verify that proper procedures were followed. During a 40-day demonstration, the system successfully generated random numbers in 7,434 of 7,454 attempts -- a 99.7% success rate. Each successful run produced 512 random bits with mathematical certainty of randomness bounded by an error rate of 2^-64, an extraordinarily high level of confidence.
