Our cameras are getting better, but that’s not always a good thing. Chinese internet security experts warn that peace sign photos could potentially be abused to collect fingerprint data.

The 2019 China Cybersecurity Week was held in Shanghai this week, and made it to the top trending topics on Sina Weibo today.

The topic attracting the attention of millions of Chinese web users is not China’s cybersecurity in general, but one that was discussed during the event, namely the potential privacy risks in making a V-sign on photos.

Chinese internet security experts at the conference warned that people are unaware that they could be giving away personal data information about their fingerprints when sharing photos of themselves making a peace sign.

If the side of the fingertips is facing the camera, and if there is not a lot of space in between the camera and the hand, it would potentially be possible to gather fingerprint data using photo enlargement tools and AI techniques.

The deputy director of the Shanghai Information Security Industry Association stated that photos displaying a fingertop-facing V-sign taken within 1,5 meter of the camera could potentially disclose 100% of one’s fingerprint information, China Press reports.

Criminals could reconstruct fingerprint patterns of other people and abuse them in various means – basically wherever fingerprint information is used to confirm people’s identities (e.g. biometric door locks or fingerprint payment scanning).

Besides not disclosing fingerprint information in photos posted online, experts also warn people not to leave fingerprint information at machines without confirming their purpose and legality.

Fingerprint scanning is used for a multitude of purposes in China. Foreigners who arrived in China since 2017 will also be familiar with the policy of collecting foreign passport holders’ fingerprints upon their arrival in the PRC.

On Chinese social media, the topic “Making a V-Sign Could Leak Your Fingerprint Data” is one of the biggest being discussed today. On Weibo, the hashtag has gathered 200 million views at time of writing (#拍照比剪刀手会泄露指纹信息#).

Some commenters advise people on social media to make peace signs with the nail side of the fingers facing the camera. (That gesture, however, is deemed an offensive gesture in some nations.)

The V-sign is often used as a rather non-symbolic or cute gesture across in East Asia.

Although in many Western countries, the symbol is mostly known as the victory sign (“V for Victory”) as used during World War II, it entered mainstream popular culture in Japan since the 1960s and spread to other Asian countries from there.

This Time article explains how the gesture appeared in Japanese manga in the late 1960s, one of them titled V is the Sign (Sain wa ‘V’ / サインはV).

Amid the concerned Weibo users, some are not worried: “It’s ok,” one commenter writes: “Using a Beauty App smoothes out my skin anyway.”

There are also many commenters who are confused about the news, wondering what advanced photo camera quality and AI technique might implicate for future privacy risks concerning face recognition data and iris scanning software (“Should we also close our eyes?”).

Others offer a different solution to the unexpected V-sign issue: “Just flip the middle finger instead.”

WeChat’s New Emoji Are Here (Including a Watermelon-Eating and Doge One)

WeChat’s new emoji are based on popular memes.

On January 14, Tencent’s Wechat introduced new emoji to its existing emoji set. The new emoji include, among others, a watermelon-eating emoji and a smiling Shiba Inu.

On Weibo, the new emoji have become a topic of discussion under the hashtags “WeChat’s New Emoji” (#微信上线新表情#), “WeChat’s Watermelon Eating Emoji” (#微信上线吃瓜表情#), and “WeChat’s Dog Emoji” (#微信上线狗头表情#).

Different from the Unicode emoji (see Emojipedia), WeChat and Weibo have their own sets of emoji, although there is overlap.

The reason why especially the watermelon-eating and dog emoji are being discussed on social media, is because these emoji are based on popular internet memes.

“Eating watermelon” (吃瓜 chī guā) is an online expression that comes from “watermelon-eating masses” (吃瓜群众 chī guā qúnzhòng), which describes a common mentality of Internet users who have no idea what is actually going on but are still commenting or following online stories for their enjoyment – perhaps comparable to the “popcorn memes” that are ubiquitous on Western social media platforms.

The smiling dog has been around since 2013 and is known as the doge meme, based on a photo of a Shiba inu. The meme was originally spread on social media platforms such as Reddit, but then also became hugely popular in China, where it became a symbol of sarcasm (also read this Abacus article on this topic).

Other new emoji are the “wow” emoji, and others to express “ok,” “add oil,” “emm,” “oh!”

There’s also a “shehui shehui” (社会社会, lit. “society society”) emoji, which also comes from online culture and is a way among friends to (self-mockingly) talk about being ‘gangsters,’ ‘brothers.’ or ‘scoundrels.’

As the new emoji are still in their testing phase, not all WeChat users can use the new emoji yet, so you might have to wait a bit before being able to try them out.

‘Good Doctor’, Digital Hospitals: How Mobile Apps Are Alleviating China’s Healthcare Problems

With the rapid digitalization of China’s healthcare, Chinese patients now have more ways than one to receive medical assistance.

China’s healthcare industry is facing some serious challenges. As Chinese society is rapidly digitalizing, mobile apps now provide innovative solutions to alleviate pressing problems in the country’s health services sector.

 
This is the “WE…WEI…WHAT?” column by Manya Koetse, originally published in German by Goethe Institut China on Goethe.de: “Good-Doctor Apps und Digitale Krankenhäuser.” 
 

Social Credit System, artificial intelligence, surveillance cameras; these are some of the hottest topics making headlines in mainstream Western media when discussing China-related developments recently.

With the rapid digitalization of Chinese society, these topics certainly have come to play a more important role in social media discussions within the People’s Republic of China (PRC). But if there is one issue that seems to concern Chinese social media users the most, it is not facial recognition nor their ‘Sesame score’: it is the topic of healthcare.

In December of 2017, a photo showing a crying mother kneeling down beside a toddler on the sidewalk in front of a Shanghai hospital went viral overnight. The moment was captured on camera by a reporter who was visiting Shanghai’s Children’s Hospital.

The photo of Guo Yinzhen and her son that went viral in China (image via NetEase, source: https://3g.163.com).

The mother, Guo Yinzhen, is a single parent who had traveled from a remote village to seek medical help for her 3-old-son, who was suffering from congenital hydrocephalus or ‘water on the brain.’ Already having traveled to the city multiple times and spending all her money on medical bills, Guo could not afford the additional 100.000 yuan (€ 12.600) for medical procedures needed to save her son’s life.

Guo’s story struck a chord with Chinese netizens, who continue to share the heartbreaking photo on social media to this day. It has become emblematic of China’s healthcare problems.

 

Crowded Hospitals and ‘Healthcare Disturbance’

 

The key to an adequate healthcare system, no matter where in the world, is that there is a right balancing in the “iron triangle” of efficiency/cost containment, high quality care, and patient access.[1] China, however, struggles with all three sides of this triangle.

Guo’s case is an extreme example, but many people in China dealing with less serious health issues and needing basic medical services also struggle to afford and access the healthcare they need.

Over 95% of people in China have health insurance, but people from different regions do not enjoy the same benefits and their out-of-pocket expenses can vary greatly. Uncovered medical costs can sometimes be catastrophic and simply unaffordable for patients and their families.

As more money flows are going to healthcare facilities in China’s cities, there is also the issue of varying levels of providers’ medical education and the overall healthcare quality, with the substantial majority of modern hospitals still existing in urban areas.

Easy access to the right kind of healthcare can be especially problematic for China’s rural population, as people often need to travel long distances and have to go through the lengthy process of registering and waiting for their doctor’s appointment, which sometimes requires them to stay in the city overnight.

For all of these reasons, China’s bigger public hospitals can get super crowded, sometimes resembling shopping malls on an end-of-season sales day. On social media, both patients and medical workers often complain about the stress brought about by the huge crowds and the shortage of doctors in hospitals across the country.

Perhaps it is no wonder that China even has a word to describe outbursts of violence between patients and doctors: ‘Yī nào’ (医闹, literally: “healthcare disturbance”).

Weibo user ‘Sunscreen’ complains about the crowds at Huashan Hospital.

One major problem within China’s healthcare conundrum is the lack of local family or primary-care doctors, which often makes bigger hospitals the first stop to any kind of medical treatment for Chinese patients.

The reasons for this issue are manifold. There is a general lack of trust in private and smaller local healthcare clinics, for example, and patients often choose to go directly to a bigger hospital to avoid making extra costs.

This makes it extra difficult for many community health care centers – that are already struggling – to make enough money and to retain qualified staff. In a society that is rapidly aging, the challenges facing China’s healthcare industry are only becoming more pressing.

 

A Doctor Today, Just an App Away

 

As China’s online environment is thriving, new innovative online apps are popping up on a daily basis. Some of these apps, that have found their ways into China’s most popular app rankings, are offering solutions to some of the country’s most pressing healthcare problems.

One of these apps is Ping’an Good Doctor (平安好医生), which was developed by health insurance provider Ping’an in 2015 and calls itself China’s “one-stop healthcare ecosystem.”

Employing some 1000 medical staff in its in-house team, contracting over 5,200 external doctors, and collaborating with 3000 hospitals and thousands of pharmacy outlets across the country, the app is somewhat of an “online hospital.”

Through the app, users can look through an online database of medical professionals, order medicine at nearby pharmacies, get 24/7 online medical consultancy, search for information about both Western and Chinese Traditional Medicine, etc., but they can also use Ping’an Good Doctor as a fitness app to track their own health.

When looking for a specific doctor for a one-on-one consult, the app first lets users select an area of expertise (e.g. dermatology or gynecology), and then offers a list of different specialists in various price categories.

Doctors from well-known hospitals, for example, or those with excellent ratings, have a one-time consultation fee of 100 yuan (€ 12,60). Other doctors can be consulted starting from 30 yuan (€3,70). All costs can be paid efficiently via online payment apps.

Doctors to pick from within the app’s various price categories.

Ping’an Good Doctor uses an AI-driven system to ask patients various questions about their symptoms and to automatically create a user’s medical record to save time. Based on the AI-generated record and the conversation with the patients – files such as photos can also be uploaded to the app -, the doctors can prescribe medicine or refer the patient to a hospital for an offline appointment if needed.

Ping’an recently announced that its number of registered users exceeded 300 million users, with 62 million monthly active users. Because the app keeps building on its AI-driven system, Ping’an Good Doctor can be expected to only become a ‘smarter’ smart health app the more popular it gets.

Although Ping’an is now leading within China’s medical app category, there are many other apps providing similar services, such as Chunyu Yisheng (春雨医生), Haodafu Online (好大夫在线), or DingXiang Doctor (丁香医生).

The emergence of these apps is just one of the many ways in which China’s digital developments, online media, and tech giants are impacting the healthcare industry, profoundly changing how patients receive healthcare information and access medical services now and in the future.

In a way, China’s medical consultation apps fill the void in offline primary care. Patients who would otherwise turn to hospital care as their first stop can now  access medical consultations any time, any day, at a relatively low cost. Those who suffer from relatively harmless conditions could be diagnosed by a medical specialist via the app and get the medicine they need within a matter of minutes. With the growing popularity of these kinds of apps, many patients no longer need to visit a hospital at all.

Are smart health apps such as Ping’an Good Doctor the solution to China’s healthcare problems? No, they’re not. Struggling mums like Guo Yinzhen will not find the help they need there. But they do contribute to a more efficient healthcare environment where crowd flows in hospitals can be reduced, and patients do not need to spend a lot of time and money to stand in hour-long queues to get five minutes of their doctor’s time.

Although smart health apps could not help Guo Yinzhen and her son, social media apps could. As soon as their story went viral in late 2017, Shanghai Children’s Welfare Foundation Xiaoxingxin offered to cover medical treatments for the little boy, with a notable pediatric neurosurgeon operating the child. According to the latest updates, the boy’s situation was “looking good.”

Hopefully, the same holds true for the challenging sides of China’s healthcare industry.
