㈠ How to promote blockchain technology to increase data security

The advantages of blockchain in information security and the software blockchain technology laboratory are based on their own development experience And technical features summarize the following aspects: 1. Use a highly redundant database to ensure the data integrity of information; 2. Use relevant principles of cryptography to verify data to ensure that it cannot be tampered with; 3. Use multiple private key rules in authority management. Perform access control.
Blockchain is decentralized and distributed. Blockchain technology is open and transparent. Currently, there is no effective way to deal with data security. In fact, data projects have limited control over personal data. During data transfer, the project cannot control how it is used later. And through the use of cryptocurrencies, blockchain provides financial incentives for institutions that maintain the network. Blockchain provides a secure storage and management of information, including personal data.

Establish a cross-regional and cross-industry data sharing platform that can be open to the entire society, strengthen data security legislation, and gradually increase the introduction of artificial intelligence and blockchain technology to promote big data and artificial intelligence, The integration of new technologies such as blockchain improves the ability to perceive, predict, and prevent risk factors.

㈡ Applications of Blockchain

The main application areas of Blockchain include: digital currency, transaction settlement of financial assets, digital government affairs, certificate depository and anti-counterfeiting data services and other fields. Blockchain is a database technology that links data blocks in an orderly manner. Each block is responsible for recording a file data and encrypting it to ensure that the data cannot be modified or forged.

Blockchain is essentially a distributed database system that uses cryptography technology for multi-party participation, joint maintenance, and continuous growth. It is also called a distributed shared ledger. Each page in the shared ledger is a block, and each block is filled with transaction records. The anonymity, decentralization, openness, transparency, and non-tamperability of blockchain technology make it highly favored by enterprises and has gained More extensive application attempts.

Blockchain application scope 1. Financial field

Blockchain can provide a trust mechanism and has the potential to change the financial infrastructure. Various financial assets such as equity, bonds, bills, warehouse receipts, fund shares, etc. It can be integrated into the blockchain technology system and become a digital asset on the chain, which can be stored, transferred and traded on the blockchain.

The decentralization of blockchain technology can reduce transaction costs and make financial transactions more convenient, intuitive and secure. The combination of blockchain technology and the financial industry will inevitably create more and more business models, service scenarios, business processes and financial products, thereby bringing more impact to the development of financial markets, financial institutions, financial services and financial formats. . With the improvement of blockchain technology and the combination of blockchain technology with other financial technologies, blockchain technology will gradually adapt to the application of large-scale financial scenarios.

2. Public service field

Traditional public services rely on limited data dimensions, and the information obtained may not be comprehensive enough and have a certain lag. districtThe non-tamperable nature of the blockchain makes the digital certification on the chain highly credible. It can be used to establish new authentication mechanisms in the fields of property rights, notarization and public welfare, and improve the management level of public services.

Relevant information in the public welfare process, such as donation projects, fundraising details, fund flows, recipient feedback, etc., can be stored on the blockchain to meet the privacy protection of project participants and other relevant laws and regulations. Under the premise of requirements, public disclosure will be made conditionally to facilitate public and social supervision.

3. Information security field

Using the traceability and non-tampering characteristics of blockchain, we can ensure the authenticity of data sources and ensure the non-forgery of data. Blockchain technology will fundamentally change information Security issues of the propagation path.

Blockchain is reflected in the following three points in the field of information security:

User identity authentication protects data integrity and effectively prevents DDoS attacks

The distributed storage architecture of blockchain will make Hackers are at a loss as to what to do. Some companies have begun to develop a distributed Internet domain name system based on blockchain to eliminate the root cause of the current DNS registration shortcomings and make the network system cleaner and more transparent.

4. Internet of Things field

Blockchain + Internet of Things can allow each device on the Internet of Things to operate independently, and the information generated by the entire network can be protected through smart contracts in the blockchain.

Security: Traditional IoT devices are highly vulnerable to attacks, data loss and maintenance costs are high. Typical information security risk issues for IoT devices include low firmware versions, lack of security patches, permission loopholes, too many device network ports, and unencrypted information transmission. The blockchain's consensus mechanism for network-wide node verification, asymmetric encryption technology and distributed data storage will significantly reduce the risk of hacker attacks.

Trustability: The traditional Internet of Things is managed and controlled by a centralized cloud server. Due to the security of the device and the opacity of the centralized server, it is difficult to effectively protect user privacy data. The blockchain is a distributed account book. Each block is interconnected and has its own independent working ability, ensuring that the information on the chain will not be tampered with at will. Distributed ledgers can therefore provide trust, ownership records, transparency and communication support for the Internet of Things.

Effectiveness: Limited by cloud services and maintenance costs, the Internet of Things is difficult to achieve large-scale commercial use. The traditional Internet of Things realizes communication between things through centralized cloud servers. The disadvantage of this model is that as the number of access devices increases, the server faces more load, requiring enterprises to invest a lot of money to maintain the normal operation of the IoT system.

Blockchain technology can directly realize point-to-point transactions, omitting the labor expenditure of other intermediaries or personnel, which can effectively reduce the costs incurred by third-party services and maximize benefits.

5. Supply chain field

The supply chain consists of many participating entities, with a large amount of interaction and collaboration. Information is discretely stored in their own systems, lacking transparency. The lack of smooth information makes it difficult for participating entities to accurately understand relevant matters.The real-time status and existing problems of items affect the collaborative efficiency of the supply chain. When disputes arise between parties, it is time-consuming and laborious to provide evidence and pursue accountability.

Blockchain can make data open and transparent among various entities, thereby forming a complete, smooth, and non-tamperable information flow throughout the entire supply chain. This can ensure that all entities promptly discover problems arising during the operation of the supply chain system and find targeted solutions, thus improving the overall efficiency of supply chain management.

6. Automotive Industry

Last year announced a partnership using blockchain to build a proof of concept to streamline the car rental process and build it into a “click, sign up, and drive” process. Future customers choose what they want The rented car enters the public ledger of the blockchain; then, sitting in the driver's seat, the customer signs the rental agreement and insurance policy, and the blockchain updates the information simultaneously. This is not an imagination, for car sales and car registration Said, this type of process may also develop into reality.

7. Stock Trading

For many years, many companies have worked to make the process of buying, selling, and trading stocks easy. Emerging Blockchain Chain startups believe that blockchain technology can make this process more secure and automated than any previous solution. At the same time, blockchain startup Chain is working with Nasdaq to enable private companies through blockchain. Equity transfer

8. Government management

Government information, project bidding and other information are open and transparent. Government work is usually subject to public attention and supervision. Since blockchain technology can ensure the transparency and immutability of information, it is very important to the government. The implementation of transparent management plays a great role. There is a certain degree of information opacity in government project bidding, and enterprises also have the risk of information leakage during the sealed bidding process. Blockchain can ensure that bidding information cannot be tampered with and can ensure the transparency of information nature, forming a common trust among competitors who do not trust each other. It can also arrange subsequent smart contracts through the blockchain to ensure the construction progress of the project and prevent the growth of corruption to a certain extent.

There are many more applications of blockchain technology, and this is just a fulcrum of blockchain applications. In the future, blockchain technology will be applied everywhere

㈣ The way blockchain solves industrialization problems

The way blockchain solves industrialization problems is to use blockchain’s unique logistics system, capital flow system and corporate supervision to promote Solving industrialization problems.

1. Logistics system: At present, in global logistics, all parties use separate databases, and each party runs a different system. Therefore, two interfaces are needed. If blockchain is introduced as a distributed global database.

It can bring the following advantages: First, consensus, all distributed accounts in the network are synchronized, and all agree on the time and content of transactions; second, traceability, the ownership of each asset is recorded.

2. Capital flow system: the basic operational flow of industrial enterprisesThe process includes market demand, technical design, customer approval, project procurement, manufacturing and production, technical inspection and delivery. There are transactions in all links. Using blockchain technology to connect these links can make any operation trustworthy, non-repudiable and non-tamperable.

3. Enterprise supervision: The traditional informatization model lacks strong data protection measures for the transmission of digital file information at various nodes, which may lead to the possibility of theft and tampering of data files. .

At present, the State Environmental Protection Administration uses a statistical system similar to ERP or SFCS. Such systems have a central server and are controlled by developers. However, in order to reduce their own burden, enterprises may find ways to improve the data. Use your hands and feet to reduce the payment of sewage charges.

The security system that blockchain technology can provide is:

The industrial Internet may expose the company's production line to the external network, even if it does not need to be connected to The public Internet avoids external attacks, but physical isolation may also lead to infection of external viruses due to management negligence.

Therefore, the Industrial Internet needs real-time network performance monitoring and early warning technology based on blockchain networks to manage industrial data in a distributed manner to avoid the huge impact of a single node being attacked on the network; at the same time, prevent unauthorized access Stricter security protection technologies such as entity identification, tracking and access are used to protect the data and network security of industrial networks.

㈤ BT110: What benefits does blockchain technology bring to the information security industry?

The significance of blockchain to the information security industry is reflected in the following three points:
1. Users Identity authentication protection
Asymmetric public and private key encryption technology uses two sets of key systems, which is more secure than symmetric encryption. Most public key encryption is implemented on the PKI platform, which can easily be used by hackers to impersonate identities. The WhatsApp vulnerability was exploited by hackers Send fake keys to perform man-in-the-middle attacks.
Blockchain can build a new identity management system. The identity identification algorithm used by business secret mail makes it difficult to conceal tampering, thus effectively preventing identity forgery.
2. Data Integrity Protection
Once the traditional encryption algorithm is tampered with by a man-in-the-middle, the participants in the network cannot detect it in time. Similar things often happen in the transaction emails of some companies: sending emails There is no problem with the person's email address, but the receiving account has been tampered with, and this type of email fraud is usually not discovered until the damage has been done.
The U.S. Department of Defense’s DARPA Advanced Research Projects Agency is considering using blockchain to protect sensitive military data. Blockchain uses a hash algorithm to store data. Data blocks are connected to each other. Any data tampering will cause changes in the block sequence value. No matter how large the network is, the source of the tampering can be easily found.
3. Effectively prevent DDoS attacks
The intensified DDoS attacks are daunting to enterprises. An advanced DDoS attack can even easily bring down a large enterprise., which is also the first choice for hackers trying to carry out large-scale damage.
The distributed storage architecture of blockchain will make hackers at a loss. Some companies have begun to develop a distributed Internet domain name system based on blockchain to eliminate the root cause of the current DNS registration shortcomings and make the network system cleaner and more transparent.
