Shanghai Airport Gets Check-In With Facial Recognition Machines

Increased convenience may come at a cost in a country with few rules on how the government can use biometric data.

It’s now possible to check in automatically at Shanghai Hongqiao airport using facial recognition technology, part of an ambitious rollout of facial recognition systems in China that has raised privacy concerns as Beijing pushes to become a global leader in the field.

Shanghai Hongqiao International Airport unveiled self-service kiosks for flight and baggage check-in, security clearance and boarding powered by facial recognition technology, according to the Civil Aviation Administration of China.

Similar efforts are under way at airports in Beijing and Nanyang city, in central China’s Henan province.

Many airports in China already use facial recognition to help speed security checks, but Shanghai’s system, which debuted Monday, is being billed as the first to be fully automated.

“It is the first time in China to achieve self-service for the whole check-in process,” said Zhang Zheng, general manager of the ground services department for Spring Airlines, the first airline to adopt the system at Hongqiao airport. Currently, only Chinese identity card holders can use the technology.

Spring Airlines, Shanghai said Tuesday that passengers had embraced automated check-in, with 87 percent of 5,017 people who took Spring flights on Monday using the self-service kiosks, which can cut down check-in times to less than a minute and a half.

Across greater China, facial recognition is finding its way into daily life. Mainland police have used facial recognition systems to identify people of interest in crowds and nab jaywalkers, and are working to develop an integrated national system of surveillance camera data.

Chinese media are filled with reports of ever-expanding applications: A KFC outlet in Hangzhou, near Shanghai, where it’s possible to pay using facial recognition technology; a school that uses facial recognition cameras to monitor students’ reactions in class; and hundreds of ATMs in Macau equipped with facial recognition devices to curb money laundering.

But increased convenience may come at a cost in a country with few rules on how the government can use biometric data.

“Authorities are using biometric and artificial intelligence to record and track people for social control purposes,” said Maya Wang, senior China researcher for Human Rights Watch. “We are concerned about the increasing integration and use of facial recognition technologies throughout the country because it provides more and more data points for the authorities to track people.” (VOA)

New Technology That Can Clean Water Twice As of Now

Novel technology cleans water using bacteria

Researchers, led by one of Indian-origin, have developed a new technology that can clean water twice as fast as commercially available ultrafiltration membranes, an advance that brings hope for countries like India where clean drinking water is a big issue.

According to a team from the Washington University in St. Louis, more than one in 10 people in the world lack basic drinking water access, and by 2025, half of the world’s population will be living in water-stressed areas.

The team led by Srikanth Singamaneni, Professor at the varsity, developed an ultrafiltration membrane using graphene oxide and bacterial nanocellulose that they found to be highly efficient, long-lasting and environment-friendly.

The membrane technology purifies water while preventing biofouling, or build up of bacteria and other harmful micro-organisms that reduce the flow of water.

For the study, published in the journal Environmental Science and Technology, they used bacteria to build such filtering membranes.

The Gluconacetobacter hansenii bacteria is a sugary substance that forms cellulose nanofibres when in water.

The team then incorporated graphene oxide (GO) flakes into the bacterial nanocellulose while it was growing, essentially trapping GO in the membrane to make it stable and durable.

They exposed the membrane to E. coli bacteria, then shone light on the membrane’s surface.

After being irradiated with light for just three minutes, the E. coli bacteria died. The team determined that the membrane quickly heated to above the 70 degrees Celsius required to deteriorate the cell walls of E. coli bacteria.

While the bacteria are killed, the researchers had a pristine membrane with a high quality of nanocellulose fibres that was able to filter water twice as fast as commercially available ultrafiltration membranes under a high operating pressure.

When they did the same experiment on a membrane made from bacterial nanocellulose without the reduced GO, the E. coli bacteria stayed alive.

The new technology is capable of identifying and quantifying different kinds of cyanobacteria, or blue-green algae, as a threat to shut down water systems when it suddenly proliferates. Pixabay

While the researchers acknowledge that implementing this process in conventional reverse osmosis systems is taxing, they propose a spiral-wound module system, similar to a roll of towels.

It could be equipped with LEDs or a type of nanogenerator that harnesses mechanical energy from the fluid flow to produce light and heat, which would reduce the overall cost.

If the technique were to be scaled up to a large size, it could benefit many developing countries where clean water is scarce, the researchers noted. (IANS)
