Recently, the news that “Tencent’s student identity information processing patent was authorized” has been on the hot topics Search. According to Tianyancha, on July 30, Tencent Technology (Shenzhen) Co., Ltd. applied for a project titled "Student Identity Information Processing Methods, Devices, Electronic Equipment and Storage Media in Blockchain Networks" in September 2019. The patent has been authorized and the announcement number is CN110532323B.

(The picture shows the basic information interface of Tianyancha patent)

What are Tencent’s considerations in developing this patent? What scenarios will it be applied to? Can it achieve the effect of improving information security and avoiding information leakage?

Accordingly, Tencent told Nandu Privacy Guard that the starting point of the patent is for scenarios such as personal information file management, and hopes to use blockchain technology to improve personal information files on the basis of protecting data security. Efficient circulation and independent controllability. Other experts said that this technology can ensure that information is difficult to tamper with, but it is not very innovative in preventing information leakage.

Tencent’s new patent was approved for similar technologies in many fields

According to the patent summary of Tianyancha, this invention provides a way to distinguish Student identity information processing method in the blockchain network, as well as information processing devices, electronic equipment and storage media. This patent can store and sell all the user’s student identity information at different stages in the blockchain network, which not only ensuresStudent identity information is fair, impartial, and cannot be tampered with, and it can also effectively improve information security and avoid information leakage.

(The picture shows the patent abstract structure diagram)

It is reported that blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. . It has rich and interesting application scenarios, can achieve collaboration, trust and consistent action among multiple subjects, and solve problems such as information asymmetry.

Nandu Privacy Guard found out that Tencent is not the first company to apply for patents on identity information processing methods and devices in blockchain networks. Since 2018, more than ten companies have applied for similar patents, covering multiple fields such as medical care, finance, and e-commerce.

Public information shows that in November 2019, Shenzhen Xiongdi Technology Co., Ltd. applied for a patent authorization titled "Blockchain-based Digital Identity Information Management Method and System"; in January 2019 In March, eBaoTech Medical Information Technology (Beijing) Co., Ltd. applied for patent authorization for "multi-dimensional dynamic identity identification methods, devices and systems based on blockchain".

Most of these companies first obtain the identity information of the target user, and after verification, obtain the public key that matches their authority information (referring to the non-secret key pair used together with the "public key algorithm" half) and encrypt it, and then complete the verification process of the identity data information in the blockchain network.

Inventor: It can improve the independent controllability of information files

Nandu Privacy Guard found that using blockchain network Processing personally identifiable information provides new ideas and methods for establishing a more secure and efficient electronic file management system. It is understood that the traditional student electronic file management system is a central information platform, and information management relies on the management platforms of each educational institution below it. They can easily become targets of cyber attacks.

At the same time, Internet application operators are the actual controllers of users' personal information. They can analyze, utilize or sell users' personal information to make profits. Users' personal information security faces various threats.

According to reports, in December 2014, a data package containing 1.3 million pieces of personal information of students who took the postgraduate entrance examination that year was sold on the Internet for a price of 15,000, involving mobile phone numbers, ID numbers, family Sensitive information such as address, school major, etc. In September 2018, the information of more than 2,600 students at Huaide College of Changzhou University in Jiangsu was leaked and used by unscrupulous companies to falsely pay wages and evade taxes.

Some people believe that such a large-scale information leak can only occur if the school file system, which holds detailed student information, is attacked.

So, what are Tencent’s considerations in developing this patent? What application scenarios will it be used for?

Nandu Privacy Guard contacted the inventor of the patent and Tencent Cloud Blockchain Senior Engineer Zhuang Xiaozhao. He said that the starting point of this patent is for scenarios such as personal information file management, of which student identity information is only one branch. He hopes to use blockchain technology to improve the efficient circulation and independent controllability of personal information files while protecting data security.

When introducing the application scenarios of patents, Zhuang Xiaozhao gave an example. Assume that before student A enters elementary school, he opens a personal student file on the blockchain and stores it encrypted. He can authorize the elementary school through the contract to maintain his own file permissions until he graduates from elementary school; when he enters junior high school, A The secondary school is also contractually authorized to maintain archives until graduation from junior high school. At this time, the primary school permission has automatically expired.

"Similarly, if A enters high school, university, or transfers to another school, A needs to authorize management. At the same time, students only have authorization or viewing rights, but do not have file maintenance rights." Zhuang Xiaozhao also said , due to the lack of efficient data circulation, the patent currently has no specific application. Taking student information files as an example, only by opening up the data circulation system of the entire education chain can it be possible to produce practical applications, and this is a long-term and gradual process.

Can Tencent’s new patent prevent information leakage?

So, what is the principle behind this patent claiming to be able to improve information security and avoid information leakage? Can such an effect be achieved?

"Information security or privacy protection is not the main function of the blockchain. We usually combine cryptography technology with blockchain technology to achieve the purpose of protecting data security on the blockchain." Zhuang Xiaozhao Analysis, "The blockchain has become a natural data circulation bridge with its 'distributed accounting model' and data non-tamperability."

General manager of Beijing Hanhua Feitian Xin'an Technology Co., Ltd. Peng Gen gave an example, saying that the technical principle of blockchain is a decentralized "distributed ledger", which can be understood as many people owning the same ledger. If someone initiates a transfer, the transfer action requires 51% of the people. Only after approval can it be successful and recorded in a block. In other words, if you want to tamper with the data inside, you also need to tamper with 51% of the account books at the same time to succeed.

Talking about the effectiveness of this patent in improving information security, Peng Gen bluntly said that due to decentralization, distributed ledgers can indeed ensure that information is fair and impartial and difficult to tamper with. If you want to tamper, you must tamper with more than 51% to succeed, which is very difficult to achieve. However, it is not very innovative when it comes to preventing information leakage.

“This patentThe innovation is that it combines encryption algorithms such as public keys and private keys with the blockchain and uses it in the new field of student identity information processing. "Peng Gen said.

❸ Is it difficult to develop a public blockchain chain? How many domestic companies can do it

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Blockchain is an important concept of Bitcoin. It is essentially a The centralized database, as the underlying technology of Bitcoin, is a series of data blocks generated using cryptographic methods. Each data block contains a batch of Bitcoin network transaction information, which is used to verify its information. Effectiveness (anti-counterfeiting) and generating the next block.

The biggest problem if such technology is to be put into application is the "impossible triangle problem"

That is, it cannot be achieved simultaneously Scalability, Decentralization, and Security can only be two out of three.

Most of the public chain projects currently on the market are difficult to put into use on a large scale.

❹ What is the recent development of blockchain? Are there any formal projects to introduce?

Analysis of expenditure scale and application prospects of China’s blockchain industry in 2018 2019 will be close to 300 million U.S. dollars per year, solving shortcomings and promoting economic development

Blockchain technology is expected to be widely used in the economic field

Blockchain technology is important for cultivating new drivers of economic growth, building an honest society, and improving Managing the level of science and technology and alleviating the financing difficulties of small and medium-sized enterprises have strong practical significance and are expected to be widely used in the economic field. Currently, the application of blockchain technology is still in the early stage of development and faces many challenges.

Analysis of unfavorable factors for the development of China’s blockchain

1. The technology is not mature enough. At present, blockchain technology is not yet mature in terms of system stability, application security, and business models, and cannot meet the requirements of "high efficiency and low energy", "decentralization" and "security" at the same time. First, performance issues. The transaction throughput that can be carried out on the blockchain is not high, and the current block capacity is very small, which leads to network congestion and high-frequency business needs are difficult to meet. Many projects are also working on optimization, but they are far from real scenarios such as banks. There is still a certain distance between the transaction throughput of , stock exchanges, etc. Second, there is the issue of consensus mechanism. In terms of energy consumption, consensus algorithms such as workload proof consume a lot of energy and cost, causing the blockchain to waste a lot of computing power and matching power across the entire network. In terms of types, the current blockchain consensus mechanisms are too few in type and will be diversified in the future. In business scenarios, a richer consensus mechanism is inevitably needed to adapt. Third, security issues. Issues such as privacy protection, harmful information on-chain, smart contract vulnerabilities, consensus mechanism and private key protection, computing power attacks, cryptographic algorithm security, etc. all make the blockchain face a severe situation of platform security and application security. Fourth, database issues. Unlike traditional databases, blockchain applications require a large number of write operations, HASH calculations, and verification operations. Database systems specifically for blockchain are still difficult to overcome.

2. The application scenario is unclear

Currently, the blockchain project is still in the exploratory stage, and no specific implementation scenario can be found. At present, promising areas include finance, sharing economy, Internet of Things, public services, etc. However, judging from the maturity of existing blockchain technology, there are still many problems in blockchain applications, and there is still a gap between actual use. First, the immaturity of blockchain technology restricts the implementation of commercial applications. Although there are currently many types of core blockchain technologies such as privacy protection algorithms and consensus mechanisms, they are generally not commercially available. Secondly, the application model of blockchain is still being explored, and the "irreplaceable" advantages of blockchain have not yet been realized. The blockchain itself represents a consensus system, and a consensus system that conforms to the corresponding business scenario should be built from a higher level, not just "business + blockchain". China has a large number of users, complex business scenarios, and any commercial product will involve a very large traffic and population, and the current blockchain technology cannot satisfy it.

3. Scarcity of professional talents

Blockchain technology is a multi-disciplinary and cross-field technology, which mainly involves operating systems, network communications, cryptography, mathematics, and finance. , production, etc., but currently our country still has shortcomings in interdisciplinary fields and fields, and the supply of talents in related fields is seriously insufficient. On the one hand, researchThere is a huge gap in technical talent. Blockchain technology research and development mainly focuses on programming languages ​​​​such as Go, Javascript, C and C+, and new smart contracts use new functional programming languages ​​​​such as Haskell, Ocaml, and Rholang. There is a huge gap in China's talent market for technical talents with senior R&D experience in relevant languages. On the other hand, there is a lack of design talent at the bottom level. Different from R&D technical talents, blockchain underlying system architecture design talents must master multiple cross-disciplinary professional skills. They must not only have an in-depth understanding of the underlying design principles of blockchain and have experience in the design of various system architectures, but also master the business logic of specific application scenarios. . Although some colleges and universities have launched cross-disciplinary education and blockchain-specific technical disciplines, professional talents are still very scarce.

Analysis of favorable factors for the development of China’s blockchain

1. Favorable policies promote development. In January 2017, the Ministry of Industry and Information Technology released the "Software and Information Technology Service Industry Development Plan (2016-2020)", which proposed requirements for innovation in blockchain and other fields to reach international advanced levels. In August 2017, the State Council issued the "Guiding Opinions on Further Expanding and Upgrading Information Consumption to Continuously Release the Potential of Domestic Demand" and proposed to carry out pilot applications based on new technologies such as blockchain and artificial intelligence. In October 2017, the State Council issued the "Guiding Opinions on Actively Promoting Supply Chain Innovation and Application" proposing to study and use emerging technologies such as blockchain and artificial intelligence to establish a credit evaluation mechanism based on the supply chain.

In March 2018, the Ministry of Industry and Information Technology released the "Key Points of the Standardization Work of the Informatization and Software Service Industry in 2018", proposing to promote the establishment of the National Informatization and Industrialization Integrated Management Standardization Technical Committee, the National Blockchain and Distributed Records Accounting Technology Standardization Committee. In June 2018, the Ministry of Industry and Information Technology issued the "Industrial Internet Development Action Plan (2018-2020)" to encourage and promote the application research of emerging cutting-edge technologies such as edge computing, deep learning, and blockchain in the Industrial Internet.

Since blockchain was first included in the "13th Five-Year Plan" National Informatization Plan in 2016, blockchain has increasingly received attention and attention from the national government. Beijing, Shanghai, Guangdong, Hebei, Twenty-four provinces, cities or regions including Jiangsu, Shandong, Guizhou, Gansu and Hainan have launched dividend policies, launched the layout of the blockchain industry chain, and actively explored industry applications based on blockchain.

2. The blockchain industry is gradually taking shape

At present, my country’s blockchain technology continues to innovate, and the blockchain industry is gradually taking shape, starting in supply chain finance, credit reporting, and product traceability. , copyright transactions, digital identity, electronic evidence and other fields are expected to promote technological changes, organizational changes and efficiency changes in our country's economic system, making important contributions to building a modern economic system. With the continuous influx of entrepreneurs and capital, the number of enterprises has increased rapidly. Blockchain applications will accelerate their implementation, promote high-quality development of traditional industries, accelerate industrial transformation and upgrading, and use blockchain technology to "reduce costs" and "reduce costs" for the real economy."Improve efficiency" and promote the standardized development of traditional industries. In addition, blockchain technology is deriving into new business formats and becoming a new driving force for economic development. Blockchain technology is promoting a new round of business model changes and becoming an important tool for building an honest social system. Important support.

3. Broad application prospects in the future

In the past, the circulation of physical banknotes was difficult to trace, but with the application of blockchain technology, all digital assets There will be a "chain" to check the flow. For example, in the financial field, blockchain is expected to solve the pain points and difficulties in the payment field, reduce the complexity of transactions, increase the end-to-end speed of transactions, and reduce communication costs in the transaction process. , improve the transparency and non-tamperability of transaction records. The cost of reconciliation, clearing, and settlement between financial institutions, especially cross-border financial institutions, has always been high, and there are complex manual processes. Blockchain technology has the characteristics of non-tamperable data and Traceability, its application can help reduce the cost of reconciliation and dispute resolution between financial institutions, can significantly improve the processing speed and efficiency of payment business, and also make small cross-border payments possible. In addition, the district The application of blockchain will also extend to many fields such as medical health, education, charity, social management, etc., and the market prospects are very broad.

❺ What are the practical application cases of blockchain in China

The most widely used application of blockchain is still in the field of financial technology, such as digital asset trading. As an underlying technology, blockchain is the technical implementation method of Bitcoin. The rapid application of blockchain technology has Virtual currencies are also needed. In the past, a large-scale economic scenario that required mutual trust and extensive collaboration among many people could only be solved through a centralized approach, which was very inefficient. The emergence of blockchain technology has solved this problem and eliminated it. Center. An important reason for getting rid of this center is that virtual currency provides an endogenous economic incentive mechanism for the blockchain, giving people the motivation to join the economic activities transformed by the blockchain. Of course, the blockchain will have more in the future Applications in wider and more mature fields. For example, in November last year, the State Grid submitted a patent application titled "Methods and Devices for Controlling Electricity Transactions with Blockchain". This year, the Xi'an City Wall International Marathon also used blockchain for the first time in the world. The technology registers all athletes' competition data, winning links and other information on the blockchain, using its traceable and non-tamperable technical features to open up information channels between various events, effectively ensuring the reliability of competition results.

❻ What blockchain projects in China that really affect society and life and have been implemented are worth mentioning

Speaking of blockchain, it can be said that there is currently no tens of millions of blockchain projects. The implementation of projects has emerged, but because of this, the imagination space of blockchain is very large. At present, major companies in various countries are deploying blockchain technology, but most of them are small-scale applications or pilots, but they are also Worth mentioning:

1. Blockchain + electronic invoice

On August 10, 2018, the country’s first blockchain electronic invoice was launched in Shenzhen. Different from traditional electronic invoices and simple electronic invoices, the blockchain electronic invoice that was implemented this time combines the "fund flow and invoice flow" into one, combines invoice issuance and online payment, and opens up invoices. The entire process of application, invoicing, reimbursement and tax filing.

The Shuqin core team has been committed to blockchain technology research and application exploration since 2013. At the beginning, the Shuqin team wanted to integrate blockchain technology with the Internet finance at that time. combine. However, how to ensure that the data saved by blockchain technology is recognized by the existing judicial system? Shuqin found that the development of the entire blockchain industry will face the same problem: judicial validity! In order to solve this industry problem, Shuqin team established Baoquan.com.

This was a problem that even Ali could not solve at the time. In order to establish a connection with the existing judicial system, the Shuqin team found Qianmai, the only identification center with data identification qualifications in Zhejiang Province at that time, and established Qianxin.com with them. After many efforts, in 2016, Qianxin.com issued the first blockchain-based electronic evidence forensic appraisal certificate.

Relying on Baoquan.com, a platform connected to the basic rules of society, Shuqin Technology is based on the vision of jointly building a new digital economic ecosystem.
