Pay attention to the security of QR code payment： how to protect the wallet after sweeping it？

　　Nowadays, QR code payment is widely used in offline micropayment scenarios such as restaurants, supermarkets and convenience stores. However, there are still hidden risks in the bar code generation mechanism and transmission process, which also leads to the risk cases of payment security, and unfair competition exists in the business promotion process of market institutions (see the report "Sweep, why is the wallet" on May 11, this edition). What measures should relevant departments and payment institutions take to ensure the safety of users’ payment? How to further improve the user experience of QR code payment?

　　Competent department:

　　Formulate technical standards and standardize business development

　　The 2017 China Third Party Mobile Payment Industry Research Report pointed out that the offline scanning code payment industry has entered an accelerated development period. On the one hand, offline scanning code payment is simple and fast, which brings users a convenient consumption experience; On the other hand, merchants who access offline scanning code payment also enjoy the increase in revenue brought by digital marketing and operation.

　　In promoting the development of industry norms, the People’s Bank of China positioned QR code payment as a small, convenient and effective supplement to bank card payment, and adopted a series of measures to standardize the development of QR code payment business. It includes the establishment of a regulatory idea that whether commercial banks or payment institutions, using bank accounts or payment accounts to carry out QR code payment, should verify the security level according to the transaction, and carry out risk control and security management through the transaction quota.

　　In recent years, with the wide application of payment marking and other technologies in mobile payment, the security standard of QR code payment has been objectively improved. The People’s Bank of China guides relevant market players to actively improve their technical level, formulate relevant technical standards, and standardize the development of QR code payment services.

　　The barcode payment business specification previously issued by the central bank has been implemented since April 1, 2018. In view of the technical risks of barcode payment, this specification puts forward a series of targeted requirements. For example, strengthen the security protection of bar codes, take measures such as payment marking, validity control and bar code anti-counterfeiting identification, improve the security protection ability of bar codes in the aspects of generation, storage, display, reading, analysis and use, and effectively guarantee the reliability and effectiveness of bar codes.

　　Because static bar codes are easy to be tampered with or altered, and it is easy to carry Trojans or viruses, the central bank stipulates that if static bar codes are used for payment, no matter what transaction verification method is used, the cumulative transaction amount of the same customer bank or payment institution in a single day should not exceed 500 yuan. The new payment regulations also require that the payment institution must have a license: "To carry out bar code payment business, the payment institution should obtain the corresponding business license according to the regulations and conduct business according to the corresponding management measures."

　　Jing Linbo, director of China Social Science Evaluation Center of China Academy of Social Sciences, believes that QR code payment still faces some problems if it wants to develop healthily. For example, QR code, a common QR code, became a national standard in 2000. A few years ago, the state issued relevant policies on QR codes, but a comprehensive standard for QR codes has not yet been issued. "In addition to formulating the business norms of QR code payment, the state should strengthen the top-level design of QR code payment, formulate comprehensive industry standards, and widely promote and use our national standards nationwide." Jing Linbo said.

　　Payment institution:

　　Strengthen security and improve payment experience.

　　As the first commercial bank to launch QR code payment products, the relevant person in charge of ICBC introduced that ICBC QR code payment has all the functions of the mainstream code scanning products in the current market, and uses the internationally leading token technology to mutate the card number to hide the real card number information and ensure the security of account funds. At the same time, through a series of security control measures such as 7×24-hour uninterrupted real-time risk monitoring, transaction limit control, large transaction verification, and 60-second mandatory update of QR code, it provides bank-level protection for customer funds and information security, and effectively improves the payment experience of users. At present, ICBC QR code payment has achieved comprehensive aggregation acceptance function, with security, compatibility and convenience, and has attracted more than 1 billion potential individual users for 5.6 million ICBC e-payment merchants, making it the largest aggregation payment platform in China.

　　China UnionPay and more than 40 commercial banks launched UnionPay China Unionpay Quick Pass QR code products. The insiders believe that this is an active exploration and innovation of large state-owned commercial banks in QR code payment, and it is a useful attempt to provide users with efficient, convenient and safe mobile payment transactions.

　　As a third-party payment platform, Alipay has also adopted a number of technical means to reduce transaction risks in "sweeping" payment. Shang Shanhu, a security expert of Alipay, said that in order to prevent information security risks and avoid being parsed out of user account or transaction order information due to the spread of QR codes, Alipay first encrypts the information that needs to be transmitted through QR codes into character strings by an encryption algorithm, and then compiles the character strings to form a QR code. Therefore, even if the QR code is acquired and scanned by others, it can only parse the encrypted character string, but can not further parse any relevant information of the user. Barcodes formed by merchants’ cashiers and by Alipay APP are time-sensitive. After expiration, new barcodes will be formed, while previously generated barcodes will be invalid, thus preventing information and financial risks caused by barcode copying and dissemination.

　　Alipay also launched the "You dare to accept, I dare to pay" protection plan: if the merchant’s money collection code is maliciously replaced or switched, its lost funds will also be paid through the insurance company.

　　User public:

　　Raise awareness of prevention, don’t just scan the code.

　　If you want to make "sweeping" safer, you can’t do without the efforts of regulatory authorities and market institutions. You also need users to raise their awareness of prevention and strengthen self-protection.

　　Industry experts reminded that users should have a sense of prevention and be vigilant, and don’t easily believe in brand promotion activities such as free code scanning and gifts in the market. There may be huge security risks hidden behind the "sweeping" behavior, such as the disclosure of personal information, and there may also be some illegal acts. In particular, don’t easily provide personal name, ID card, bank card, telephone number, mailing address and other information. Even a credible QR code application may be maliciously used by some hackers and criminals to become malicious QR codes, so we should always be vigilant.

　　Shang Shanhu suggested that with the popularity of two-dimensional codes, users should master some relevant knowledge and common cases of two-dimensional codes to raise their awareness of safety precautions. At the same time, we should develop good habits of using mobile phones, including downloading tools and software in official website, not scanning the code, and installing anti-virus software in mobile phones.

Recently, Aunt Li from Huangpu, Shanghai, thought about eating out for the New Year’s Eve dinner next year, so she went to the Electric Xinghualou to consult about the New Year’s Eve dinner, only to be told that the New Year’s Eve was nearly full.

　　The reporter learned from Xinghualou that the box on New Year’s Eve is the most tense every year. Many guests have finished this year’s dinner and booked the next year’s dinner directly. Therefore, the boxes on New Year’s Eve will be fully booked in the first half of the year. Although the lobby is more abundant, it still needs to be booked in advance.

　　According to the relevant person in charge of Xinghualou, the bookings from the first day to the sixth day are equally hot. Many Shanghai families are now more willing to book a reunion dinner for a large number of people in the first month, and only choose to eat with small families.

　　In view of a small number of spare seats outside the important time nodes, many hotels have launched promotions such as full reduction and discounts, and also launched New Year’s Eve packages with different dishes and different prices for the public to choose, and the prices are basically the same as in previous years.

　　Table for four, table for six.

　　More suitable for small families

　　Many people who came to book the New Year’s Eve dinner also found that compared with the previous table and meal for only 10 people, many old-fashioned New Year’s Eve dinner packages have also undergone new changes this year:

　　Xinghualou has added 4-person meals, 6-person meals and 8-person meals, as well as supporting tables for 4-6 people and 8 people;

　　In addition to the box for 10 people, Shanghai Dongjiao Hotel also has meals for 4 people and 5 people in different halls.

　　The New Year’s Eve package of Drunk West Building is also divided into three grades: four, six and eight.

　　The relevant person in charge of Xinghualou said that this measure was also adjusted according to many customers’ feedback. Considering that many Shanghai families are mostly small families, it is easy to waste food by booking a meal for 10 people, so corresponding reforms have been carried out to facilitate customers to choose according to their needs and have a good year.

　　In addition, the services of popular time-honored brands have also been upgraded. Mr. Huang Lao, who often eats New Year’s Eve dinner outside, said that the service of the old brand is becoming more and more humanized. If the itinerary changes after booking the New Year’s Eve dinner, you only need to contact the store in advance. Whether it is a refund or a change of time, the operation is quite flexible.

　　The takeaway package will be on sale soon.

　　In addition to the time-honored New Year’s Eve dinner, it is also worth looking forward to for some diners who don’t grab the New Year’s Eve dinner and want to have a good meal. With the improvement of the technology of semi-finished dishes, the taste of many time-honored take-away New Year dishes is getting higher and higher, and the patterns are becoming more and more abundant.

　　As it is still early for the Chinese New Year, most of the time-honored take-away New Year dishes have not been booked yet. However, the reporter has mastered some "spoilers" in advance.

　　According to the person in charge of a well-known time-honored brand, as a special delicacy at the New Year family banquet, there will be several packages for consumers to choose from this year, including cold dish packages and cake packages.

　　Nowadays, the time-honored take-away New Year’s Eve dinner packages in Shanghai often provide online shopping channels in addition to the traditional ways such as going to the store and booking by telephone. Customers can enter the corresponding time-honored WeChat WeChat official account or Micro Mall to place an order. Please pay attention to the specific information page or consult the store.

The body is slim, the size is moderate, and it is suitable for holding. The "forehead" and "chin" are symmetrical to each other.

　　In terms of color scheme, Meizu E3 has champagne gold, obsidian black and danqing 3 color schemes to choose from. Today’s Xiaoshan experience of this Meizu E3 is danqing, compared with the more common black and red on the market, the recognition can be said to be very high.

　　It is worth mentioning that the Charm Blue E3 uses an inward recessed side fingerprint identification key, which is an integrated non-pressable button design. Unlike this model equipped with side fingerprint recognition, the Charm Blue E3’s fingerprint identification key and power button are separate, and the power button is on the upper part of the fingerprint identification key. This design can be said to be very user-friendly and will not cause unnecessary accidental touches.

　　In terms of hardware configuration, the Meizu E3 uses the Qualcomm Snapdragon 636 processor, while the Qualcomm Snapdragon 636 uses the big.little architecture, with four Qualcomm Kryo260 cores and four Kryo260 cores, providing very powerful performance.

This Super mCharge is a shrunken version that provides 10V/2A fast charging, and the 20W charging power can fill a 3360mAh battery in 95 minutes. Super mCharge’s charge pump technology can improve charging speed while effectively reducing heat generation. Whether it is playing games or daily use, it is very handy.

　　We mainly take a look at the photography effect of the Meizu E3. As a thousand-yuan model, the photography effect of the Meizu E3 can definitely be said to be very brilliant. The Meizu E3 adopts a rear dual camera design.

　　The main camera is 12 million pixels, with a maximum aperture of f/1.9, and supports dual PD full-pixel dual-core focusing. Its CMOS sensor is the Sony IMX362 previously used for the Meizu Note6, with a unit pixel area of 1.4 μm, and supports the ArcSoft algorithm. This algorithm integrates functions such as multi-frame noise reduction, HDR, and portrait blurring.

With the development and application of large-scale language models and ChatGPT-like technologies accelerated by major companies, the potential risks of these artificial intelligence technologies and how to develop and apply them reasonably have attracted much attention. Thousands of top people, including Musk and stephen wozniak, the co-founder of Apple, have publicly called on AI Lab to suspend training more powerful models for six months in order to formulate and implement relevant security protocols.

According to the latest reports from foreign media, SV Angel, a top investment company, will convene executives and employees of top companies in the field of AI R&D to discuss the formulation of standards for using AI technology.

The foreign media mentioned in the report that this meeting convened by SV Angel will be held on Wednesday local time. Representatives from companies such as OpenAI, Microsoft, Google, Apple and NVIDIA are expected to attend, and the participants are expected to discuss how to continue to develop AI in the most responsible manner.

When Musk and others called for a six-month suspension of training more powerful models, they mentioned in their letters that AI labs and third-party experts should use the suspension time to jointly formulate and implement the shared security protocol for advanced AI design and development, and related protocols are strictly reviewed and supervised by third-party experts.

At the management meeting on April 9th, JD.COM Retail established the latest organizational structure reform framework, which mainly included the following contents:

Cancel the business group system and change it into the business division system, and the person in charge of the original business group will be the person in charge of the business division;

Each business department under the unified management of the original business group will be divided into specific business units according to the subdivided categories, giving the category leaders more decision-making autonomy, including the rights of personnel appointment and dismissal;

In addition, in the split business unit, there will be no distinction between POP and self-operation, and the two will be fully opened and managed by a unified category manager, further realizing the "equal rights" of traffic.

This is the biggest organizational restructuring of JD.COM retail in the past five years after the business division was upgraded to a business group system in 2018. It is also the first time that JD.COM has opened up its own business and POP since it set foot in the POP business, and truly realized a plate of goods. (Source: 36Kr)

It can be said that although My AI may not be as good as generative artificial intelligence that can talk freely in terms of "intelligence", at this stage, it can obviously provide more and more practical help for the work. (Source: Fast Technology)

A study in university of vermont found that TikTok content related to food and nutrition continued unhealthy food culture among young users, while the voice of experts was basically absent on the platform. Researchers advocate a shift to a weight-inclusive nutrition, and rethink the attitude of society towards body, food and health.

The research was recently published in PLOS One magazine, and found that the information of weight norms, that is, the idea that weight is the most important criterion to measure a person’s health, is dominant on TikTok, and the most popular video beautifies weight loss behavior, and takes food as the main means to achieve health and weight loss. These findings are particularly worrying in view of the existing research that shows that the use of social media by teenagers and young adults is related to abnormal diet and negative body image.

Lizzy Pope, a senior researcher, said, "Every day, what millions of teenagers and young people are taught on TikTok is very unrealistic and inaccurate in describing food, nutrition and health. TikTok, which is caught in the trend of losing weight, may be a very bad environment for the audience, especially for the main users of the platform, that is, young people. (Source: cnBeta)
