Detailed ways

In order to enable those skilled in the art to better understand the technical solutions in the embodiments of this specification, the technical solutions in the embodiments of this specification will be described in detail below in conjunction with the drawings in the embodiments of this specification. Obviously, the described implementation The examples are only a part of the embodiments in this specification, not all the embodiments. Based on the embodiments in this specification, all other embodiments obtained by those of ordinary skill in the art should fall within the scope of protection.

The technical solutions provided by the embodiments of this specification will be described in detail below with reference to the accompanying drawings. As shown in FIG. 1, FIG. 1 is a schematic flow chart of a method for depositing evidence of infringement based on a depositing blockchain according to an embodiment of this specification. The process specifically includes the following steps S101 to S107.

S101: Receive a monitoring request sent by a user equipment, and determine data to be monitored according to the monitoring request, where the data to be monitored includes user works related to the user.

The data to be monitored here can be user works in various forms such as documents, pictures, music, videos, codes, etc., which can be protected by copyright.

In actual applications, the data to be monitored uploaded by the user does not need to be authorized. For example, an original picture in a press release created by a user that day can be uploaded as data to be monitored to prevent competitors from copying and reprinting. Of course, the data to be monitored uploaded by the user can also be an authorized work. For example, novels, software, etc. that have been registered.

For example, on the client side, "registered works" or "unregistered works" are provided for users to choose, so as to better meet user needs.

Based on this, in an embodiment, the user may also be identified before receiving the data to be monitored sent by the user. For example, verification is performed based on the ID card picture provided by the user, and after the verification is passed, the ID number of the user is bound.

Furthermore, if the user selects the "registered work" to upload, it is necessary to match the owner's information contained in the "registered work" with the user's identity (for example, ID number), and the data to be monitored has been confirmed The attribution relationship with the user is opened after the match is passed, so as to avoid invalid evidence collection and reduce system overhead.

In an embodiment, the data to be monitored may be user works that have been previously stored in the blockchain. That is to say, after the user passes the identity verification, the data to be monitored is stored on the evidence block chain, so that on the one hand, it can ensure that the user's work will not be tampered with, and on the other hand, the relationship between the user's work and the user can be clarified.

S103: Determine the work identification information of the data to be monitored, and obtain a suspected infringing work that matches the work identification information.

The work identification information is the information used to uniquely identify the work on the public network. Based on this, the hash value of the data to be monitored can be determined as the work identification information.

Of course, it is also possible to intercept part of the content of the data to be monitored, and use the hash value of the part of the data to be monitored as the work identification information. For example, for a novel, the content in the first paragraph in the second chapter can be taken, and the hash value of the content can be used as the work identification information.

For registered works, there is usually a unique registration number. At this time, the registration number can also be used to uniquely identify the work. Therefore, the unique registration number of the work can also be used as the work identification information of the data to be monitored.

In practical applications, for documents, information such as the name of the work, the keywords of the work, and key paragraphs can be used as the work identification information. For example, for a novel, you can first determine the names of multiple main characters contained in it, and arbitrarily combine the keywords of multiple works, so as to determine the combined phrase as the work identification information.

And, it is also possible to obtain key paragraphs in the document, for example, the index part, the opening paragraph, or the ending paragraph as the key paragraphs, and use these key paragraphs as the work identification information.

If the data to be monitored is a video, a specified number of frames can be extracted from the video. Video is actually composed of continuous still pictures, for example, a general video is 30 frames per second.

Based on this, a specific extraction can be performed from the video, for example, the 20th frame picture in the 5th second of the video can be extracted as the work identification information. Of course, you can also extract multiple pictures specified and combine them as work identification information.

After determining a piece of work identification information of the data to be monitored, public network monitoring can be started based on the user's choice. The public network refers to the Internet in a broad sense. The way of monitoring can be real-time monitoring of a number of predetermined target websites by default.

Specifically, the server device itself can perform public network monitoring, or it can call other monitoring service providers to perform monitoring, and receive suspected infringing works returned by other monitoring service providers. For example, the server equipment invokes monitoring services provided by other service providers such as Alibaba Cloud and Tencent Cloud to obtain suspected infringing works.

Based on online infringement, the evaluation method of the degree of infringement of the data to be monitored is generally related to the number of views. Therefore, the method of determining the target website can also be based on indicators such as the number of views and click-through rates of each website or webpage. Make sure.

In practical applications, the initiation of monitoring can be started after the data to be monitored is uploaded, or it can be initiated by the user based on user needs.

For example, users can actively configure the monitored objects and the monitoring duration (for example, 1 year). For example, the user can enter the domain name of the website that needs to be monitored; or, for certain authorized websites, they can add to the whitelist and not monitor.

The specific monitoring method needs to be based on the aforementioned work identification information. For example, an auxiliary public network scan is performed based on the name of the work. After it is determined that a target website discloses a target resource with the same name, the work identification information (for example, hash value) in the target resource is determined. If the identification information of the work is exactly the same as the identification information of the work to be monitored, or the similarity between the two is not lower than a certain threshold, it is determined that the target resource is a suspected infringing work, and there is infringement on the target website.

S105: Collect evidence for the suspected infringing work, and generate evidence collection information.

A specific way of obtaining evidence may be to determine the Uniform Resource Locator (URL) of the suspected infringing work, and generate forensic information including the URL and the suspected infringing work. For example, a screenshot of the URL of a page that provides a suspected infringing work is taken, and a picture containing the URL and the suspected infringing work is generated as evidence information.

Further, while displaying suspected infringing works, some target websites may also contain further detailed forensic information (for example, click volume, sales volume, display start time, etc.) of suspected infringing works, and other information at this time It is also necessary to save. Therefore, in an embodiment, periodic screenshots may be taken of the page containing the usage information of the suspected infringing work to generate a picture sequence containing the usage information; the picture sequence of the usage information is determined as forensic information.

For example, if an unauthorized music download is provided on a CRBT platform, and it has been on the download list for a long time, you can take screenshots of the download list every 24 hours to obtain a series of infringements about the music. The detailed circumstances are used as important supporting evidence in the pursuit of liability.

In an embodiment, video recording of the infringement of the target website can also be performed to obtain more intuitive evidence collection information.

S107. Construct a target transaction that includes the forensic information, and send the target transaction to the node device of the attestation block chain, so that the node device broadcasts the target transaction in the attestation block chain, and sends the target transaction to the target transaction. After the transaction completes the consensus, the target transaction is written into the deposit certificate blockchain.

Block chains are generally divided into three types: Public Blockchain, Private Blockchain and Consortium Blockchain. In addition, there are many types of combinations, such as private chain + alliance chain, alliance chain + public chain and other different combinations. Among them, the most decentralized one is the public chain. The public chain is represented by Bitcoin and Ethereum. Participants who join the public chain can read the data records on the chain, participate in transactions, and compete for the accounting rights of new blocks. Moreover, each participant (ie, node) can freely join and exit the network, and perform related operations. The private chain is the opposite. The write permission of the network is controlled by an organization or institution, and the data read permission is regulated by the organization. In simple terms, the private chain can be a weakly centralized system with strict restrictions and few participating nodes. This type of blockchain is more suitable for internal use by specific institutions. Consortium chain is a block chain between public chain and private chain, which can realize "partial decentralization". Each node in the alliance chain usually has a corresponding entity or organization; participants are authorized to join the network and form a stakeholder alliance to jointly maintain the operation of the blockchain.

The deposit blockchain involved in the embodiments of this specification may be any one of a public chain, a private chain, or a consortium chain. The target transaction (transfer) described in this manual refers to a piece of data that is created by the node device of the attestation blockchain and needs to be finally released to the distributed database of the attestation blockchain. The server device can be a member of the node device in the certificate blockchain network, or it may not be the node device in the certificate blockchain network.

In one embodiment, after receiving the data to be monitored sent by the user, the server device may also generate a unique unified evidence number for the data to be monitored. For example, the hash value and system time of the data to be monitored can be further selected. Hopefully, the unified evidence number of the data to be monitored can be obtained. Correspondingly, when constructing a target transaction that includes the forensic information, a target transaction that includes the forensic information and a unified evidence number can be constructed.

Further, the server device may also determine the generation time of the target transaction, establish and store the correspondence between the unified evidence number, the hash value of the target transaction, and the generation time of the target transaction. For example, create an index table, in which the unified evidence number is the main key, and the hash value and generation time of the target transaction are used as the value. Of course, the index table can also contain other more information, for example, the relevant credible time in the work to be inspected. The credible time refers to the time provided by a credible timing agency.

For example, in one embodiment, each time the user successfully uploads the work to be detected, the hash value of the work to be detected can be determined, and the hash value can be uploaded to a trusted timing agency. The trusted timing agency determines the moment when it receives the hash, digitally signs the moment with the hash value, and generates a timing certificate. The trusted agency’s digital signature included in the timing certificate guarantees the The time is the credible time provided by the credible timing agency. The time at this time can be called the credible storage time, so that the credible storage time can also be written into the index with the unified evidence number as the main key.

For another example, in an embodiment, since the user needs to initiate active monitoring, based on this, it is possible to determine the unified evidence number, receive the monitoring instruction initiated by the user, generate a monitoring transaction containing the monitoring instruction, and then The monitoring transaction is written into the deposit certificate blockchain network. In practical applications, monitoring transactions can also contain auxiliary information such as monitoring logs.

Furthermore, the generation time of the monitoring transaction can be determined (as mentioned above, the credible time for generating the monitoring transaction can also be obtained), and the unified evidence number, the hash value of the monitoring transaction and the generation of the monitoring transaction can be established. The corresponding relationship of time is written into the aforementioned index with the unified evidence number as the primary key.

For another example, in an embodiment, when the suspected infringing work is determined and evidence is obtained, the related evidence collection instruction (which can be initiated by the user or the service) can be obtained when collecting evidence for the suspected infringing work. The end device automatically initiates after the infringement is determined), generates a forensic transaction including the forensic instruction, and writes the forensic transaction into the attestation blockchain network. As mentioned earlier, forensic transactions can also include forensic operation logs and other information related to forensic operations.

Furthermore, the generation time of the forensic transaction can be determined (as mentioned above, the credible time for generating the forensic transaction can also be obtained), and the unified evidence number, the hash value of the forensic transaction and the generation of the forensic transaction can be established. The corresponding relationship of time is written into the aforementioned index with the unified evidence number as the primary key.

As shown in FIG. 2, FIG. 2 is a schematic diagram of an index with a unified evidence number as the main key provided by an embodiment of this specification. In the index table, the credible storage time, the credible time for generating the target transaction, the credible time for generating the monitoring transaction, and the credible time for generating the forensic transaction can also be arranged in chronological order. It should be noted that the aforementioned target transaction, forensic transaction or monitoring transaction is only a functional description. In essence, they can be stored in the same blockchain network and have the same data structure or generation method.

In an embodiment, the node device may also receive a query request sent by the user, and the query request includes a unified evidence number. In this way, the node device can obtain at least one hash value of the target transaction, forensic transaction or monitoring transaction from the aforementioned index table, so as to obtain the corresponding target transaction, forensic transaction or monitoring from the blockchain network according to the hash value. At least one of the transactions, and return the transaction obtained in the query to the user

Of course, in practical applications, the target transaction, forensic transaction, or monitoring transaction corresponding to the unified evidence number can generally be returned together, and the credible time corresponding to each exchange can also be returned to the user separately, thereby realizing the return from the deposit To the complete evidence chain for forensics, and there are credible timing agencies in the evidence chain to ensure the accuracy of the time sequence of each transaction, and the characteristics of the blockchain can ensure that each transaction cannot be tampered with. As shown in FIG. 3, FIG. 3 is a schematic diagram of a system framework structure provided by an embodiment of the specification.

In an embodiment, if the server device is a member of the blockchain node device and is a node device with verification function, it can also accept the hash value sent by the user at this time (usually, It is the hash value corresponding to a certain exchange in the target transaction, forensic transaction or monitoring transaction), verify the integrity of the target transaction corresponding to the hash value, and return the verification result to the user so that the user can conduct the transaction at any time Integrity verification. Transaction integrity verification refers to verifying whether a transaction has been tampered with in the blockchain network. Blockchain verification based on hash value is already very mature in current technology, so I won't go into details here.
