"A preliminary study finds that facial recognition algorithms struggle to identify people wearing masks. The study tested 89 commercial facial recognition algorithms, and the best had error rates between 5% and 50% in matching unmasked photos with photos of the same person wearing a digitally-applied mask. Masks both lowered the algorithms' accuracy rates and raised the number of failures to process. The more of the nose is covered by the mask the lower the algorithm's accuracy; however, error rates were generally lower with round masks; and the algorithms generally performed worse with black masks than with surgical blue ones. False positive remained stable or declined a small amount."

"Japanese supercomputer simulations showed that wearing two masks gave limited benefit in blocking viral spread compared with one properly fitted mask. The findings in part contradict recent recommendations from the U.S. Centers of Disease Control and Prevention (CDC) that two masks were better than one at reducing a person's exposure to the coronavirus. Researchers used the Fugaku supercomputer to model the flow of virus particles from people wearing different types and combinations of masks, according to a study released on Thursday by research giant Riken and Kobe University."

"There are currently no usable photo data sets of mask-wearing people that can be used to train and evaluate facial recognition systems. The NIST study addressed this problem by superimposing masks (of various colours, sizes and positions) over images of faces, as seen here:"

"A new strain of ransomware has been targeting government agencies and educational institutions in the United States, through scam emails that pretend to be something important. The malware, dubbed as 'MarsJoke' by Proofpoint security researchers, reportedly began a large-scale email campaign which distributed the cryptomalware last week. The developers are sending out emails which seems to be masked as a message from an airline company."

""The combination of the coronavirus, facial recognition on our phones, fear of surveillance, and late-stage capitalism really struck a chord with the internet," said Baskin."

"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."

"This week, the company released a new form of facial recognition called periocular recognition, which can supposedly identify individuals by just their eyes and eyebrows. Rank One says the new system uses an entirely different algorithm from its standard facial recognition system and is specifically meant for masked individuals. Rank One says it will ship the technology to all of its active customers for free."

"The January snow lay thick on the Moscow ground, as masked officers of the FSB - Russia's fearsome security agency - prepared to smash down the doors at one of 25 addresses they would raid that day. Their target was REvil, a shadowy conclave of hackers that claimed to have stolen more than $100m (£74m) a year through "ransomware" attacks, before suddenly disappearing. As group members were led away in cuffs, FSB officers gathered crypto-wallets containing untold volumes of digital currency such as bitcoin. Others used money-counting machines to tot up dozens of stacks of hundred dollar bills."
