Cybersecurity Experts Warn: Flicking the V-Sign in Photos Could Give Away Your Fingerprint Data

V-sign selfie pictures could disclose personal information about your fingerprints, security experts warn.

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.”

Key Players, Digital Trends & Deep Dives: China Internet Report 2021

SCMP just launched its latest China Internet Report. (And What’s on Weibo readers can get a 30% discount on the Pro Edition!)

Published

on

As China’s tech sector has been facing an ongoing crackdown by Beijing regulations, a lot has been changing in the country’s digital environment over the past year. The new China Internet Report 2021 by SCMP gives an overview of the latest trends and developments.

When it comes to China’s online landscape, nothing ever stays the same. Over the past year, political, economic, and social developments and measures have once again changed the Chinese digital environment.

Giving a comprehensive overview of the key leaders and major trends dominating the Chinese online field, South China Morning Post (SCMP) issued its fourth annual China Internet Report.

China’s internet population has now risen to 989 million – last year’s report indicated an internet population of 904 million. By now, there are 853 million mobile payment users, which indicates that over 86% of the entire mobile internet population uses mobile as a way to pay.

As China’s internet population is still growing, and new online startups are still popping up every day, there have been tightening regulations on multiple fronts.

As laid out in SCMP’s report, regulations mainly focus on the four areas of antitrust, finance, cybersecurity, and data privacy. Regulatory actions targeting the monopolistic behaviours of China’s biggest internet companies are still ongoing, and the new Data Security Law came into effect on September 1st of this year.

While Chinese tech companies are seeing increased scrutiny at home, they have also been facing intensifying geopolitical tensions between China and other countries. Over the past year, the various probes and shutdowns into Chinese companies by countries such as the US and India have meant a serious blow to the market share of Chinese apps.

Meanwhile, the SCMP report highlights the trend of various older and newer Chinese (e-commerce) apps “downplaying” their Chinese origins when entering foreign markets. Shein is a good example of this development, but other players including Zaful, Urbanic, and Cider are also experiencing more success outside of China while not explicitly marketing themselves as Chinese e-commerce apps.

Another noteworthy trend explained in the new report is how China’s shifting demographics are creating new niche segments to compete over. The COVID-19 crisis is partially a reason why China has seen an increase in senior internet users, with an increasing number of online products and content catering to the elderly.

China’s Ministry of Industry and Information Technology (MIIT) even issued special guidelines earlier this year for web pages and mobile apps to carry out so-called “elderly friendliness modifications.” Since this user group is still expected to see significant growth, the “silver economy” is an area that will only become more important in the years to come.

To check out all the main trends for 2021, China’s latest internet statistics, its top tech competitors, internet companies, and more, here’s a link to the free report.

The free report is 55 pages long and gives an overview of China’s latest internet numbers and players, covers the top cross-sector trends for 2021, including the tightening regulations and the bumpy road ahead for China’s tech IPOs.

The Pro Edition of China’s Internet Report 2021, also launched by SCMP, is 138 pages long and provides a deep-dive into ten relevant sectors – featuring insightful and useful analysis, data, and case studies relating to China’s e-commerce market, content & media, gaming, blockchain, fintech, online education, healthtech, smart cars, 5G, and Artificial Intelligence.

The China Internet Report Pro Edition is priced at US$400, but the team at SCMP has kindly reached out and made it possible for us to offer a special 30% discount to What’s on Weibo readers.

You’ll get the discount by using the discount code: WHATSONWEIBO30, or by clicking this link that will automatically include your discount code.

How Social Media Is Speeding Up Zhengzhou Flooding Rescue Efforts

Chinese social media are speeding up local rescue efforts after Zhengzhou saw the heaviest rain in 1,000 years.

Published

on

Social media is utilized as a tool in the response to the floodings in Henan province. Once again, Weibo facilitates active public participation to provide immediate assistance to the people facing this natural disaster. 

On Tuesday, July 20, heavy rainfall caused major disruptions in the central province of Henan. The amount of rain over the last three days in Zhengzhou is reported to be the same as what it would usually receive in an entire year.

It is reported that Henan Province has initiated the highest-level emergency response to floods, and China’s State Flood Control and Drought Relief Bureau has dispatched a workgroup to Henan, initiating level III emergency response rescue work.

Since the evening of July 20, news and information streams on the heavy rains and floods have been dominating Chinese social media. In the midst of the disastrous events, Weibo has become an online space for people seeking help, those disseminating information on available resources, and for other related activities that help netizens engage in emergency management and accessing information.

The volume of such messages is huge, with thousands of netizens seeking ways to help speed up rescue work and actively contribute to the emergency relief efforts.

The organically improvised response protocol on social media includes the following guidelines:

  • Verify, summarize, highlight, and spread online help requests posted by people from different locations
  • Remind people to delete help-seeking posts once they have been rescued or have found assistance.
  • Disseminate relevant knowledge relating to emergency care and response, and public health information, such as how to deal with different disaster scenarios, warning people about the safety of drinking water during floods, etc.
  • Share information regarding mental health and psychosocial support during the different phases of the disaster.

 

When posts of people trapped by the heavy rain started to be published on Weibo, many online influencers, no matter what subject they usually focus on, participated in spreading help-request posts that were not getting a lot of online attention.

Erdi 耳帝, a music influencer with nearly 15 million fans on Weibo, has been retweeting the online posts of people asking for help since the night of July 20.

The social media influencer Erdi has been kept retweeting asking-for-help posts since the night of July 20.

An example of such an online emergency help request (求助贴) is the following post of July 21st, 17:15 local time:

Our entire neighborhood is cut off from water and electricity, the water level is rising to chest level, and we currently have no drinking water at the moment. Need help urgently.

Status: Verified, pending rescue.
Seeking help: Wu M**, phone 13*****27
Number of people to be rescued: five or six thousand
Location: Zhengzhou City, Henan Province, Zhengdong New District, Shangdu / Xuzhuang Street intersection, east courtyard of Shangdu Jiayuan Muzhuang district (we can’t exit the building, there is no water, no electricity, no supplies, and it’s been 24 hours)

Once people who have been trapped by the water are rescued, the user who published the post will delete the original post to make sure other emergency posts are also noticed and disseminated.

Some Weibo users engage in organizing scattered online information in one single post, e.g. posts regarding local electricity leakage, making this information more accessible and easier to understand.

One post that was among the top-shared ones this week, is a picture that includes contact information of rescue teams of both officials and civilians. When realizing that some people were unable to upload the picture due to poor internet connections caused by the heavy rain, an up-to-date and full-text version was quickly shared by netizens.

Some Weibo users listed various methods to get assistance for hearing-impaired and deaf-mute people affected by the floods, advising people to download various apps to help to communicate and translate.

Besides the more general practical advice and emergency action plans shared by Chinese social media users, there are also those who pay attention to the importance of personal hygiene during these times. Some are sending out information about menstrual hygiene needs during floods, reminding women to frequently change sanitary pads and try to keep the genital area clean and dry due to the risk of infection. A hashtag related to menstruation during the flooding momentarily ranked fifth in the top search lists (#河南暴雨 如果你出在经期<).

Information on mental health support is disseminated all across social media.

People also try to provide mental support in other ways. A student orchestra spontaneously performed at the Zhengzhou station, where dozens of passengers were left stranded in the night. The video clips of the performance went viral, with the young musicians playing two widely-known songs, “My People, My Country” (我和我的祖国) and “Ode to the Motherland” (歌唱祖国). Many social media users shared the clips and expressed how the performance moved them to tears.

Some video clips that show how ordinary people save ordinary people amid such a natural disaster have also been widely shared. One video shows citizens of Zhengzhou standing in a line and use a rope to pull people from an underground floor where they were trapped by the water flooded.

In all the aforementioned ways and many more, Weibo has become a public platform for Chinese people to respond to the Henan disaster, efficiently communicate and keep track of help requests, organize and disseminate related information, and provide access to timely knowledge and relevant advice.

With so many online influencers and ordinary netizens voluntarily joining in, the online information flows are quickly circulating, allowing for necessary public communication channels while other resources and communication methods are still overwhelmed or in the making. The last time Weibo was used as an efficient emergency communication tool was during the early days of the COVID19 outbreak in Wuhan.

“Please stand strong, Zhengzhou” and “Hang on, Henan,” many commenters write: “Help is underway!”
