China won't let its plans for CBDC be derailed

When the International Olympic Committee announced this week that the 2022 Beijing Winter Olympics will be open "exclusively to spectators residing in China’s mainland, who meet the requirements of the COVID-19 countermeasures”, it threw a spanner in the works for the CBDC party.

China's Central Bank Digital Currency "CBDC" is called the e-CNY, aka digital yuan. It is currently being trialled throughout mainland China and is “on the home straight” for being ready for the Beijing Winter Olympics in February, according to Fan Yifei, deputy governor of the People’s Bank of China.

The restrictions for the Winter Olympics is a major blow as this would have been would a global showcase for the e-CNY given the huge influx of foreign visitors.

Wiser! readers will remember that a couple of months back I interviewed Richard Turrin, THE expert on China's transition to a cashless society and their move to be the world's first major economy with a digital version of their sovereign currency.

China: the journey to a cashless society
Newsletter #15 (Premium): Central Bank Digital Currencies are coming. It’s not a question of whether, but when. And China has stolen the march and is years ahead of the rest of the world.

Richard posts expert comments and analysis every day on Linkedin about China-related tech news. You can follow him here. (It's worth it!)

On Thursday this week, Richard wrote this about the decision to close the Beijing games to foreign visitors and its impact on the CBDC.

"The 2022 Beijing Olympics were going to be the international “coming out” party for China’s new CBDC. A showcase of new technology all designed to put CBDC cards in the hands of tourists so that they could experience going “Cashless” "China-style" for the first time.

"An entire e-CNY ecosystem is being built with this tourist-focused tech:

👉Tourist cards: a CBDC hard wallet the size of a credit card with a tiny e-ink screen.

👉Tourist card dispenser: Insert a $100 bill and the machine spits out a new e-CNY card or adds balance.

👉Point Of Sale systems: All POS systems including things like vending machines are all CBDC ready.

👉ATM: A CBDC enabled ATM that adds balance with funds taken from a foreign credit card.

👉Mobile apps: CBDC ready mobile apps so that tourists can use mobile wallets if they choose.

👉CBDC gloves: Ok these may be a stretch but so your hands won’t get cold gloves with a built-in CBDC wallet."

My take: it may be a missed PR opportunity but this won't stop China's pursuit of the bigger goal, which is to be a digital economy unlike anywhere else in the world. This is about more than just replacing coins and notes with a digital code you can use on your mobile phone.

The bigger picture is about removing the friction, cost and barriers to trading that exist in the current financial systems and mechanisms.

China is building a technical infrastructure for the 21st century that is built on digital currency, blockchain trading systems and a bloc of Belt and Road Initiative trading partners that do not rely on the US Dollar as the trading currency.

Imagine CBDCs carried on blockchain technology that can make cross-border payments in seconds, instead of days. And at half the cost. That's what's coming.

America is still contemplating its navel when it comes to CBDCs, and lawmakers are conflating cryptocurrencies with digital ones (a CBDC is not a cryptocurrency.)

Twitter’s AI found to have racial bias

In a rare act of transparency from BigTech, Twitter opened up its image-cropping algorithm to public scrutiny. Twitter's AI ethics team held a public competition to find bias in the algorithm after a white user noticed that Twitter’s AI had cropped out his black colleague in a photo where both of them were present, only displaying him.

The issue is that whilst AI has created the ability to recognise a face or apply filters to an image, these same AI algorithms can also reflect unconscious bias when making its decisions. This comes about because AI algorithms are computer programs that are trained using real human beings.

So, if the majority of the coders are white males or the training of the algorithms is done using students on a college campus, the outcomes will not reflect the diversity of a global population.

To tackle this issue, Twitter announced in late July that the company would hold the first-ever “algorithmic bias bounty challenge.”

In early August anyone could peruse the code underpinning Twitter’s image-cropping algorithm, then submit a bias assessment for the chance to win one of five cash prizes up to $3,500. The algorithm in question had been used by Twitter since 2018 and has now been decommissioned.

Twitter received nearly 50 submissions from the week-long review. First prize went to a university researcher who found that the algorithm prioritized young, slim, and lighter-skinned faces.

Other winners found that the algorithm rarely chose to feature people pictured in wheelchairs, that it preferred emojis with lighter skin tones, and that for memes, it was more likely to showcase English text than Arabic script.

The issue comes down to something called "saliency".

Saliency algorithms are widely seen as a shortcut for identifying the most important or relevant aspects of a photo. It’s also the type of model that Twitter had used to crop images in the algorithm under review.

The problem with saliency is that the algorithms are trained via human eye-tracking, e.g., where someone’s eyes go first when shown an image. This makes the training of the AI open to unconscious bias.

Twitter praised the contest entry as important in a world where many of us use camera and editing apps that apply beauty filters before we share photos with friends or on social media. That can distort our expectations of attractiveness.

Beauty and apps filters are widespread. Facetune promises to help you "stand out on social media", whilst B612 offers a "smart beauty" tool that can recommend changes to your face shape and other appearance changes. However, Google has disabled its automatic touch-ups by default in its Pixel camera app after concluding that beautification filters can "negatively impact mental well-being." Google has also stopped calling its adjustments "beauty" filters.

Pegasus Spyware

Wiser! readers will remember that I covered the Pegasus Spyware issue back in June in issue #25. The latest news is that 5 French ministers may have been targeted by Israeli NSO's Pegasus Spyware. The ministers' cellphones had 'suspicious marks,' according to a leaked document, suggesting at least an attempt to infect the device with the Pegasus spyware in 2019. Source: Haaretz, Wiser! #25
