Lockpicking With Sound

Researchers at the National Unviersity of Singapore have developed a system called SpiKey that can predict 10 possible options of a key design just by recording the sound of a key in a lock. Of the 586,584 possible key combinations for a 6-pin lock, SpiKey can be used on approx. 56% of them to generate candidate key options that will open the lock.

COVID-19 Detection Through Speech

Researchers MIT's Lincoln Laboratory have identified a way to recognise COVID-19 in asymptomatic people by analysing their speech patterns. The theory that the constriction of muscles caused by a COVID-19 infection could affect speech in otherwise asymptomatic people was put to the test by analysing speech from video interviews of asymptomatic celebrities before and after their postive diagnosis.

Free Wolfram Engine for Developers

Wolfram have launched their Wolfram Engine as a free package for developers. Described by Stephen Wolfram himself on his blog, the Wolfram engine implements the Wolfram Language, which in turn offers a huge range of computational intelligence and algorithmic processing, access to the Wolfram Knowledgebase as well as over 5000 abstracted functions like machine learning, visualisation and image computation.

Real Time Hidden Acoustic Signals

Researchers in China and the U.S. have created a system for receiving hidden data in audio signals using smartphone microphones. The Dolphin system uses commercial off the shelf (COTS) smartphones to detect, error correct and decode hidden data transmitted in audio within an 8 meter distance and up to an angle of 90 degrees. Transmission of sport stats data via stadium speakers without the need for internet connectivity is one possible implementation of this mass transmission system.
