Will IPFs bring a piracy free network era?
IPFs can effectively protect and encourage content creation. In terms of copyright confirmation and genuine verification, it can achieve data credibility, copyright protection and transaction credibility. In terms of preventing piracy, it can give priority to duplicate inspection and protection through technologies such as "file fingerprint" and "file de duplication".
On November 1, the personal information protection law was officially implemented, and building a secure boundary for the use of information and protecting personal information in an all-round way once again became a hot topic.
At present, with the popularity of the Internet, the problem of user privacy disclosure is receiving great attention. In July this year, Zhejiang communications administration investigated that on November 11, 2019, Alibaba cloud disclosed the registration information retained by the user to third-party partners without the user's consent. Subsequently, Alibaba cloud reported that the incident had been seriously dealt with and actively rectified in accordance with the company's system. The copyright owner of this year's hit series "anti Mafia storm" issued a statement, saying that the full version of the sample film sent for approval by "anti Mafia storm" was exposed on the Internet and widely spread in a very short time, which has seriously disturbed the normal broadcasting order of the film.
At present, the world has gradually entered the digital era, data has become the core production factor of enterprises, and any data security event has a great impact. One after another data leakage incidents targeting users and enterprises occur frequently, which makes many people pay attention to the emerging blockchain technology. How to make the data no longer "transparent" through the unique advantages of tamper proof, traceability and full link transparency of blockchain? Relevant experts answered this.
Blockchain is decentralized
"At present, the new IT infrastructure built with blockchain technology as the core is improving the related problems of data security from the underlying architecture." He Jin, Professor of blockchain Industry School of Chengdu University of information engineering, said that blockchain technology, abbreviated as BT (blockchain Technology), also known as distributed ledger technology, can be simply understood as a "distributed shared database", It has three main characteristics: open and transparent information, difficult to tamper with records, and non centralization without relying on intermediaries.
"The main role of blockchain is to make data traceable and trustworthy, so as to promote the evolution of information internet to value Internet. In the system that has used blockchain technology, the trust problem of all parties involved can be effectively solved by automatically executing smart contracts without the audit of central institutions." He Jin said, The system architecture based on blockchain has the characteristics of decentralization, which can be tamper proof, traceable and transparent all links. It provides a new path to solve the problems of certificate storage, transaction and rights protection in fields such as network copyright. Many content giants at home and abroad have begun to use blockchain to solve the persistent problem of piracy.
On April 9, 2020, the opinions of the CPC Central Committee and the State Council on building a more perfect market-oriented allocation system and mechanism of factors were published, and the data were written into the document as a new type of production factor. The efficient allocation of data elements requires the reform of data resource allocation system and mechanism matched with the reform of market economy from the perspective of transaction marketization; It is also necessary to provide technical support from the perspective of technical implementation. Blockchain technology is an important supporting technology in the era of digital economy.
In May this year, the Ministry of industry and information technology and the state network information office issued the guiding opinions on accelerating the application of blockchain technology and industrial development, which further defined the development objectives of the blockchain industry in the next 10 years: by 2025, the comprehensive strength of China's blockchain industry will reach the world advanced level and the industry will begin to take shape; By 2030, the comprehensive strength of China's blockchain industry will continue to improve and the industrial scale will further expand.
"The release of the guidance indicates that the top-level design of China's blockchain development has been basically completed, which has important guiding significance for the overall development of the industry." He Jin said that with the increase of policy efforts and the continuous maturity of blockchain technology, blockchain has begun to show its edge in anti-counterfeiting traceability, supply chain management, judicial deposit, government data sharing, livelihood services and other scenarios.
However, blockchain technology itself still faces problems such as security, credibility and scalability. Limited by many factors such as underlying technology, scenarios and commercialization, blockchain has not really realized large-scale implementation.
Blockchain "upstart" IPFs can effectively protect digital information
As a mainstream system protocol in the blockchain technology field, IPFs (interplanetary file system) has caught fire in recent years. IPFs is also called "interstellar file system". It is a point-to-point distributed file system protocol. You can understand it as a network transmission protocol for network content storage and file sharing.
"In the IPFs protocol, how files are stored, indexed and transmitted in the system is defined in advance, that is, the uploaded files are converted into a special data format for storage; at the same time, IPFs will hash the same files to determine their unique address." He Jin said that the biggest difference between IPFs and HTTP protocol is that HTTP passes through the domain name (web address) To find the text, pictures, music, video and other content stored in the network, commonly known as "web address addressing"; IPFs looks for network files through file fingerprints (hash values), commonly known as "content addressing".
We are no stranger to "URL addressing". "Content addressing" can be understood as that when you want to see a movie, you only need to enter the movie name into the search box, and the movie will be presented directly. Without a series of complex operations, it can better ensure the user's sense of experience. In this regard, he Jin added that when the server nodes based on IPFs protocol develop to a certain extent, there will be no single point of failure, that is, there will be no phenomena such as "404 inaccessible", and the rapid exchange of data between nodes can be realized without mutual trust.
In terms of preventing piracy and information leakage, IPFs is a "potential stock" in the blockchain technology industry. Chen Xu, a distinguished industry tutor of the school of blockchain industry of Chengdu University of information engineering, believes that the main application scenarios of IPFs include search engine, file transmission, social media, content platform, etc.
It is understood that once the security sensitive data stored on IPFs and protected by blockchain authorization and additional security mechanism is found to be copied and disseminated, it may touch the IPFs smart contract. The system will destroy or warn the file and record this error at the same time, so as to provide reliable data for subsequent accountability and traceability.
Chen Xu believes that on the premise that the Internet infrastructure and underlying data are mature, IPFs can effectively protect and encourage content creation. In terms of copyright confirmation and genuine verification, IPFs can achieve data credibility, copyright protection and transaction credibility. In terms of preventing piracy, IPFs can give priority to duplicate inspection and protection through technologies such as "file fingerprint" and "file de duplication".
IPFs is expected to become a new "tuyere" of information industry
In recent years, in response to the national call for new infrastructure, domestic telecom operators have established distributed storage infrastructure. Alibaba cloud, Tencent cloud, Huawei cloud, Inspur and other enterprises are entering the layout of IPFs. At the same time, some technical service providers focusing on decentralization have also become exporters of the underlying technology community.
"At present, the infrastructure of smart city construction in major cities mostly adopts distributed storage, so that the upper application can withstand the huge data flow. After years of development, it has formed a certain scale and application, especially the whole network computing power of IPFs has obvious advantages," He Jin said, Some Internet technology enterprises are participating in the wave of exploration and research of this new technology.
Jiang Yin, a researcher at the digital governance research center of the school of blockchain industry, Chengdu University of information engineering, also believes that IPFs technology, as an important supporting technology in the era of digital economy, its research and application will largely meet the requirements of all walks of life for data security, so as to realize the effective protection of enterprises and people's digital information assets. "The integrated development of IPFs technology will serve enterprises and people in government affairs, finance, medical treatment, education, law and other industries," he said.
"Although some enterprises are actively exploring and developing the market, it should be noted that the advantages of IPFs are relative. Only when there are enough storage nodes based on IPFs protocol can they give full play to their great advantages. At present, many practical applications are distributed storage based on a single ecology, so the storage cost is not reduced, but the hardware investment cost is increased. In this regard, the government or leading enterprises need to take the lead to build a unified application platform for trusted blockchain research and trusted distributed storage, "Jiang Yin said.
In this regard, Chen Xu also believes that according to the development law of IT technology, continuous research and practice are needed to form large-scale applications, including the government strengthening policy support and guidance, universities and scientific research institutions strengthening research and cultivating talents, and enterprises should cultivate the market more prospectively and actively. "The government, universities, scientific research institutions and enterprises should work together to build an ecosystem of talents, theory, technology and market, cultivate 'new species' in the new ecology and apply them to daily production and life, so as to form sustainable vitality and value," he said.
