All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The data left by the user on the internet belongs to the user, and generally cannot be used by others without permission. In 2018, the GDPR act, also known as the general data protection regulation, was issued by the european union. It is a regulation of all european union individuals regarding data protection and privacy in the european union law, and relates to the export of personal data outside the european context. The primary goal of GDPR is to take the citizen's and resident's control over personal profiles and to simplify the unified specification within the european union for international commerce. China subsequently promulgated similar regulations.
Some commercial products for protecting digital assets of users are already available, however, most users cannot remember all data left on the internet, so that the digital assets extracted by the product background are not complete, and the data protection is not complete enough. Based on this, the embodiment of the invention provides a digital asset acquisition method, a digital asset acquisition device and electronic equipment, which are applied to the technical field of block chains and distributed web crawlers, and particularly designs an automatic call user digital asset uplink system, so that colleges and universities can quickly find user data and register the user data into the block chains.
For the convenience of understanding the embodiment, a detailed description will be given to a digital asset acquisition method disclosed in the embodiment of the present invention.
Example 1
The embodiment of the invention provides a digital asset acquisition method, which is applied to a server, wherein the server is in communication connection with a digital asset management maintenance platform; and the user terminal is in communication connection with the digital asset management maintenance platform.
Data left by a user on the internet is called digital assets, which are registered into the blockchain system so that the data has an owner and the rights established for the digital assets are owned by the user. The novel application mode of computer technologies such as block chain distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and the like is essentially a decentralized database. The digital asset management maintenance platform is used for communicating with a user terminal, and the user terminal can be a mobile phone, a tablet personal computer, a computer and other devices with communication functions.
Based on the above description, referring to the flowchart of a digital asset acquisition method shown in fig. 1, the digital asset acquisition method includes the following steps:
step S102, acquiring personal information of a user to be processed, which is sent by a digital asset management maintenance platform; the personal information comprises an address list, an asset name and a user name; the personal information is obtained from a log of the user terminal.
The digital asset management maintenance platform is used for acquiring personal information of a user to be processed and sending the personal information to the server. The personal information can be summarized by a user and is sent to the digital asset management maintenance platform from the user terminal; or the user terminal directly sends the self log to the digital asset management maintenance platform, and the digital asset management maintenance platform directly obtains the self log from the log.
The address list refers to a list of addresses where the digital assets of the user exist, each address in the address list corresponds to at least one digital asset, and it should be noted that the digital assets corresponding to each address in the address list may also be the same digital asset, and there may be a duplication. Asset name generally refers to the name of a digital asset. The user name generally refers to the name of the user to be processed, and can be a real name or a network name.
And step S104, crawling the digital assets of the user to be processed from the Internet based on the personal information.
After the server acquires the address list, the corresponding digital assets can be extracted from the address list to be used as the digital assets of the user to be processed. After the server acquires the asset name, the corresponding digital asset can be searched from the Internet according to the asset name; after the server obtains the user name, the digital assets corresponding to the user name can be searched from the Internet.
Extracting digital assets may be in a manner that crawls from the internet. Crawling is also called crawling, which is a technology for searching data and downloading related data on the internet using a network retrieval technology. Particularly, a distributed crawler mode can be adopted, the distributed crawler is a crawler system which uses a decentralized network node to perform parallel network crawler, the distributed crawler has high efficiency, and the distributed crawler is a necessary infrastructure of most search engines.
Step S106, recording the digital assets in a preset block chain system.
When a user submits data information and links of new digital assets, or a product background automatically discovers internet data corresponding to the new digital assets of the user, the back end of the product records the data information and registers the data information in a blockchain system, and establishes ownership of the assets to ensure the asset right of the user.
The embodiment of the invention provides a digital asset acquisition method, which comprises the steps of receiving personal information of a user to be processed, which is sent by a digital asset management maintenance platform, wherein the personal information is acquired from a log of a user terminal; and crawling the digital assets from the Internet based on the personal information and recording the digital assets in a preset blockchain system. The personal information obtained from the log of the user terminal can ensure no omission, so that the personal information is complete, all digital assets of the user can be obtained, and the complete protection of the digital assets is realized.
Example 2
The embodiment of the invention also provides another digital asset acquisition method; the method is realized on the basis of the method of the embodiment; the method focuses on describing a specific implementation manner for crawling digital assets of a user to be processed from the Internet based on personal information. Another digital asset acquisition method, as shown in fig. 2, is a flow chart, comprising the steps of:
step S202, acquiring personal information of a user to be processed, which is sent by a digital asset management maintenance platform; the personal information comprises an address list, an asset name and a user name; the personal information is obtained from a log of the user terminal.
Referring to an overall framework diagram of a digital asset acquisition method shown in fig. 3, as shown in fig. 3, a server includes a crawler system and a blockchain system, the crawler system is used for crawling digital assets; the blockchain system is used to record digital assets.
The digital asset acquisition method mainly comprises a digital asset management and maintenance platform and a server cluster, and a user registers personal information to a back-end management and maintenance platform through the digital asset platform. And after receiving the registration information, the back-end platform submits the user information to the server cluster platform. The server cluster system is a distributed system. After receiving the user information, the server cluster searches all internet data related to the user in the network, registers the data information into a block chain, and establishes index information. This information is eventually returned to the user. The back-end management maintenance platform is used for designing an asset and user database and storing and maintaining digital assets of users.
And step S204, crawling the digital assets of the user to be processed from the addresses included in the address list.
The process of crawling the digital assets by the crawler system can be seen from a schematic diagram of the crawling process of the digital assets shown in fig. 4, and as shown in fig. 4, the cluster system is composed of a large number of distributed server nodes. In a completely centerless state. Each server node runs two processes internally. One is a crawler process responsible for crawling user data, and the other is a blockchain process responsible for running a blockchain system. When the server node receives the user information, the crawler process automatically searches and downloads the corresponding user data in the internet according to the information (including the specified address list, asset name, user name, asset abstract, asset update time, etc.). When data is searched, consistent hash acquisition is needed, wherein the consistent hash acquisition refers to mapping addresses to host nodes through a hash ring, and hash stability can be kept under the condition that the nodes change, so that hash efficiency and stability are improved.
After the server obtains the address list, the digital assets corresponding to the addresses can be extracted according to each address in the address list to serve as the digital assets of the user to be processed.
And S206, crawling the digital assets corresponding to the asset names from the Internet.
After the server obtains the asset name, the digital asset corresponding to the asset name can be crawled from the internet according to a crawler process in the crawler system and used as the digital asset of the user to be processed.
And S208, crawling the digital assets corresponding to the user names from the Internet.
After the server acquires the user name, the digital assets corresponding to the user name can be crawled from the Internet according to a crawler process in the crawler system and serve as the digital assets of the user to be processed.
Step S210, recording the digital assets in a preset blockchain system.
Digital assets are recorded in a blockchain system, which may be referred to as blockchain transactions, and when a transfer transaction is conducted between two accounts in a blockchain, transaction information is linked up, and such transaction information cannot be deleted or changed. Specifically, user data is handed to the blockchain process, the blockchain process records the user data in the blockchain in a blockchain mode, one party of transaction is the user's own address, and the other way is a public user. The purpose of blockchain transactions is to link user data in the chain, and the transaction itself is of little significance, so that the transaction is completed with a common account. And taking the address obtained after the transaction as a user data index and returning the user data index to the user.
The personal information may include an asset summary and an asset update time in addition to the address list, asset name and user name. The asset abstract is a brief description of digital assets owned by a user, and the server can crawl electronic assets from the Internet according to the asset abstract, and the specific method comprises the following steps: and extracting some keywords from the asset abstract, and crawling the electronic assets from the Internet based on the keywords. The asset update time is used for explaining the update time of each electronic asset, and the latest electronic asset can be crawled from the Internet.
After recording the digital assets in the preset blockchain system, the server also sends the address information of the digital assets recorded in the blockchain system. Specifically, the address information is sent to the digital asset management maintenance platform, and the digital asset management maintenance platform sends the address information to the user terminal.
The method provided by the embodiment of the invention is based on the block chain and the distributed crawler, acquires the personal information of the user to be processed, automatically finds the digital assets of the user to be processed on the Internet, and registers the digital assets into the block chain system.
