Detailed Description

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

Referring to fig. 1, fig. 1 is a network architecture diagram of a work management method according to an embodiment of the present application. In fig. 1, when the publishing platform 10 needs to publish a new work, a work publication request needs to be sent to the blockchain 20, where the new work is carried in the work publication request (for convenience of description, hereinafter referred to as a target work), and the blockchain 20 may determine the creator 30 of the target work based on the internal node and obtain authorization information of the creator 30. While determining whether the work distribution request submitted by the distribution platform 10 is a valid request based on the authorized work, the authorized object information, and the authorized period information in the authorization information, the blockchain 20 may determine whether to allow the distribution platform 10 to distribute the target work based on the authorization information of the creator 30. When the work distribution request submitted by the distribution platform 10 is a valid request, a confirmation message for allowing distribution may be returned to the distribution platform 10 to enable the distribution platform 10 to distribute the target work and determine the hash value of the target work. Further, after the target work is distributed by the distribution platform 10, a work distribution image (such as a distribution page screenshot) generated by the distribution platform 10 when the target work is distributed may be acquired and transmitted to the creator 30, so that the creator 30 signs the work distribution image by using its own private key to obtain a distribution information ciphertext. Alternatively, blockchain 20 may send the authorization information of creator 30 to distribution platform 10 such that distribution platform 10 signs the authorization information with its own private key to obtain the authorization information ciphertext. Further, the blockchain 20 may acquire the authorization information ciphertext generated by the distribution platform 10, the public key of the distribution platform 10, the distribution information ciphertext generated by the creator 30, and the public key of the creator 30, and send the authorization information ciphertext generated by the distribution platform 10, the public key of the distribution platform 10, the distribution information ciphertext generated by the creator 30, and the public key of the creator 30 to the consensus node to enable the consensus node to verify the validity of the authorization information ciphertext and the distribution information ciphertext, and send a signature confirmation message after the verification passes. When the signature confirmation message sent by the consensus node meets a preset consensus policy, it may be explained that the authorization information ciphertext and the release information ciphertext are valid ciphertexts, at this time, the authorization information ciphertext, the release information ciphertext, and the hash value of the target work may be stored in the blockchain, and the creator 30 and the release platform 10 may be returned to the target block height, so that the creator 30 views the release information ciphertext and the hash value of the target block from the blockchain 20 based on the target block height, and the release platform 10 views the authorization information ciphertext and the hash value of the target work from the blockchain 20 based on the target block height.

Referring to fig. 2, fig. 2 is a flow chart of a work management method according to an embodiment of the present application. The work management method shown in fig. 2 may include the following steps S101 to S107.

S101, receiving a work release request submitted by a first release platform.

In some possible embodiments, when the first distribution platform needs to distribute the target work, a work distribution request may be submitted to determine whether the target work can be distributed, and the work distribution request carries the target work, so that after receiving the work distribution request carrying the target work, the blockchain may determine whether to allow the distribution platform to distribute the target work based on the target work. The target works include, but are not limited to, a written work, an image work, a video work, etc., and may be specifically determined based on an actual application scenario, which is not limited herein.

S102, acquiring first authorization information of an author of the target work, and determining whether the work release request is a valid request based on the first authorization information.

In some possible embodiments, after the work release request of the first release platform is acquired, an creator of the target work may be determined, and first authorization information of the creator for the target work may be acquired, so as to determine whether the work release request submitted by the first release platform is a valid request based on the first authorization information of the target work. Specifically, the first authorization information includes information such as the first authorized work, the first authorization object information, and the first authorization, so that platform information of the first distribution platform and a time of submitting the work distribution request can be obtained, the first authorized work and the target work can be compared, and if the first authorized work is consistent with the target work, the first authorization information obtained from the creator can be described as effective authorization information. The platform information of the first distribution platform may be further compared with the first authorization object in the first authorization information, and the commit time of the work distribution request may be compared with the first authorization period at the same time. If the platform information of the first distribution platform is consistent with the first authorization object information, the first distribution platform is informed of the distribution authorization of the creator to the target works, and if the submitting time of the work distribution request is within the first authorization period, the first distribution platform is informed of the distribution period allowed by the creator when the work distribution request is submitted. Therefore, only when the target work is consistent with the first authorized work, the platform information of the publishing platform is consistent with the first authorized object information, and the submitting time of the work publishing request is within the first authorized period, the work publishing request submitted by the first publishing platform can be determined to be a valid request, otherwise, the work publishing request submitted by the first publishing platform can be described as an invalid request, and the publishing platform is not allowed to publish the target work at the moment.

For example, referring to fig. 3, fig. 3 is a schematic diagram of authorization information provided by an embodiment of the present application. The authorization information shown in fig. 3 is an authorization of the creator "Zhang Sano". Wherein, the first party (i.e. the creator) is Zhang Sanand the second party (i.e. the authorized object information) is the self-media platform of XX limited company, and the first party prescribes the obligation of the rights of the two parties, the illegal contents, the condition of ending the authorization and the like for the authorized matters of the work (i.e. the authorized works). It is not difficult to see from fig. 3 that the authorization time of the creator for the target works is from 2013, 07, 18 to 2014, 07, 18, so it is assumed that when a work distribution request submitted by a distribution platform is received at this time, only if the target works carried by the work distribution request are consistent with "person eating potatoes" in the authorization, and the distribution platform is a "XX limited company self-media platform" in the authorization, and the submission time of the work distribution request is from 2013, 07, 18 to 2014, 07, 18, the distribution platform can be allowed to distribute works "person eating potatoes".

S103, if the work release request is an effective request, determining a hash value of the target work, and returning a confirmation message allowing release to the first release platform.

In some possible embodiments, when the product release request is a valid request, a confirmation message that allows release may be returned to the first release platform to cause the first release platform to release the target product. Meanwhile, as the first distribution platform is about to distribute the target work, the hash value of the target work can be determined at the moment so as to store the hash value of the target work into the blockchain after the first distribution platform distributes the target work. When the hash value of the target work is determined, different types of hash determination modes can be adopted according to different types of the target work. Specifically, when the target work is a written work, a hash calculation can be performed on the target work by adopting a message digest algorithm to obtain a hash value of the target work. The hash values obtained by different information summarization algorithms are different in length, form of expression and the like, and specific information summarization algorithms can be determined based on actual application scenes and are not limited herein. For example, a hash value expressed in 8-bit hexadecimal numbers can be obtained based on CRC32, a hash value expressed in 32-bit hexadecimal numbers can be obtained based on MD5, and a hash value of 32 bytes (256 bits) in length can be obtained based on SHA 256.

Optionally, when the target work is an image work, scaling the target work to obtain a gray image with a preset size, and calculating gray values of each pixel point of the scaled image to obtain the gray image of the target work. Therefore, the hash value of the target work can be determined based on the gray value of each pixel point of the gray image of the target work, or the gray image of the target work can be further subjected to discrete pre-change to obtain a discrete image of the target work, and the hash value of the target work is determined based on the frequency domain value of each pixel point of the discrete image. The preset size is a size capable of highlighting the image features of the target work, and specifically may be determined based on the actual size of the target graphic and the actual application scenario, which is not limited herein. When calculating the Gray value of each pixel of the scaled image, the Gray value corresponding to each pixel may be obtained based on any one of a floating point algorithm (gray=r×0.3+g×0.59+b×0.112), an integer method (gray= (r×30+g×59+b×11)/100), a shift method (gray= (r×76+g×151+b×28) > > 8), and an average method (gray= (r+g+b)/3), where Gray represents the Gray value, R represents the red value, G represents the green value, and B represents the blue value. Optionally, the green value corresponding to each pixel point may be determined as the gray value corresponding to the pixel point, and the specific implementation manner may be determined based on the actual application scenario, which is not limited herein.

Specifically, when the hash value of the target work is determined based on the gray value of each pixel of the gray image, the gray average value of all the gray values of the gray image may be obtained, each gray value of the gray image may be traversed to compare each gray value of the gray image with the gray average value, the gray value greater than the gray average value may be recorded as 1, the gray value not greater than the gray average value may be recorded as 0, and a data sequence composed of 0 and 1 may be obtained, and at this time, the data sequence may be determined as the hash value of the target work. The number of bits of the hash value (data sequence) of the target work is consistent with the number of gray values in the gray level image, for example, the size of the gray level image is 8×8, the gray level image contains 64 gray level values, and the hash value of the corresponding target work is a data sequence consisting of 64 0 or 1. It should be noted that, the order of traversing each gray value to compare it with the gray average value may be determined based on the actual application scenario, each gray value is compared only once, and the order of 1 or 0 corresponding to each gray value in the data sequence coincides with the traversed order of the gray value.

For example, referring to fig. 4, fig. 4 is a schematic diagram of a scenario for determining a hash value of a target work according to an embodiment of the present application. Suppose that the target work is scaled to obtain a scaled image of 8×8, and the scaled image is converted into a gray image to obtain the gray image of the target work in fig. 4. At this time, the sequence from the first gray value of the first line to the last gray value of the last line in the gray image of the target work can be compared with the gray average value of 5.73 to obtain a 64 data sequence. Taking the gray value of the last line of the gray image of the target work as an example, the gray values of 11, 2, 10, 4, 15, 4, 6 and 3"8 can be compared with the gray average value of 5.73 to obtain a data sequence of 10101010 according to the comparison sequence, wherein the data sequence is the last 8 data sequences of the hash value of the target work.

Specifically, when determining the hash value of the target work based on the frequency domain value of each pixel point of the discrete image of the target work, the frequency domain average value of the frequency domain values of all the pixel points can be first obtained, each frequency domain value of the discrete image is traversed to compare each frequency domain value in the discrete image with the frequency domain average value, the frequency domain value greater than the frequency domain average value is recorded as 1, the frequency domain value not greater than the frequency domain average value is recorded as 0, and then a data sequence consisting of 0 and 1 can be obtained, and at this time, the data sequence can be determined as the hash value of the target work. The number of bits of the hash value (data sequence) of the target work is consistent with the number of frequency domain values in the discrete image, for example, the size of the discrete image is 8×8, the discrete image contains 64 frequency domain values, and the hash value of the corresponding target work is a data sequence consisting of 64 0 or 1. It should be noted that, the order of traversing each frequency domain value to compare it with the frequency domain average value may be determined based on the actual application scenario, each frequency domain value is compared only once, and the order of 1 or 0 corresponding to each frequency domain value in the data sequence is consistent with the traversed order of the frequency domain value. Optionally, after the gray-scale image is subjected to discrete cosine transform to obtain a discrete image, in order to reduce the comparison frequency of the frequency domain values and obtain the hash value of the target work at last, the hash value of the target work can be represented by the same, at this time, a part of the discrete image with a lower frequency domain value (low frequency part) can be taken from the discrete image, and a data sequence which is also composed of 0 or 1 is determined as the hash value of the target work by adopting the manner of determining the hash value of the target work based on the discrete image. The number of the longitudinal pixels and the number of the transverse pixels of the partial discrete image are consistent, and the specific selection mode is not limited herein.

For example, as shown in fig. 5, fig. 5 is another schematic view of determining a hash value of a target work according to an embodiment of the present application. As shown in fig. 5, it is assumed that the target work is scaled to a scaled image with a size of 32×32 and converted to a gray image, and then the gray image with a size of 32×32 is obtained, and further the discrete image in fig. 5 is obtained after the discrete cosine transform. At this time, a first pixel point at the upper left corner of the discrete image may be selected to select a discrete image with a size of 3*3, where the low-frequency part of the discrete image with 32×32 gray values in the discrete image 3*3 is the frequency domain mean value of the frequency domain values of the discrete image 3*3 is not difficult to obtain at this time. At this time, the frequency domain values of 3*3 are arranged according to a certain sequence to obtain a frequency domain value sequence of '0.1, 0.3, 0.2, 0.3, 0.1, 0.3, 0.2', and each frequency domain value in the frequency domain value sequence is compared with a frequency domain mean value of 0.21 (more than the frequency domain mean value is recorded as 1 and less than the frequency domain mean value is recorded as 0.21), so as to obtain a data sequence '010101010', and the data sequence '010101010' is the hash value of the target work.

Optionally, when the target work is a video work, binary data of the video work can be determined, and hash calculation is performed on the binary data by adopting a message digest algorithm to obtain a hash value of the target work. The hash calculation of the information summary algorithm can refer to the calculation mode of the written works, and is not repeated here.

In some possible embodiments, the instant first distribution platform is authorized by the creator, but because the creator's work itself has the potential for infringement, i.e., the target work may be the same or similar to other works, it is necessary to determine whether there is a target hash value in the blockchain that is consistent with or has a hamming distance from the hash value of the target work that is less than a preset hamming distance before returning a confirmation message to the first distribution platform that allows distribution. If the target hash value consistent with the hash value of the target work or the Hamming distance smaller than the preset Hamming distance exists in the blockchain, the target work is identical or similar to the work corresponding to the target hash value, and at the moment, the relevant information of the identical work or similar work can be returned to the first distribution platform and the creator so that the first distribution platform and the creator can determine whether the target work is an infringement work. If the target hash value consistent with the hash value of the target work or the Hamming distance smaller than the preset Hamming distance does not exist in the blockchain, the fact that the work identical or similar to the target work does not exist in the blockchain is indicated, the fact that the target work authored by the creator does not have infringement is indicated, and at the moment, a confirmation message allowing release can be returned to the first release platform. The preset hamming distance may be determined based on the actual application scenario, which is not limited herein. It should be noted that, because the hash value of the target work is determined by adopting the information abstraction algorithm, when a bit of data in a word or binary data in the target work is changed, the hash value of the target work will have a large difference from the hash value before the change, so when the target work is a word or video work, it is only necessary to determine whether the target hash value consistent with the hash value of the target work exists in the blockchain. When the target work is an image work, it may be determined whether there is a target hash value in the blockchain that is consistent with the hash value of the target work or that has a hamming distance that is less than a preset hamming distance.

For example, referring to fig. 6, fig. 6 is a schematic view of a scene of a determined similar work provided by an embodiment of the present application. In fig. 6, it is assumed that the target work is a picture, the hash value of the target work is 01110000 00011000 10101000, the hash value of one work in the blockchain is 01110110 00011010 10101011, and it is not difficult to find out after the hash value of the target work is compared with the hash value of another work in a para-position, and the data corresponding to the 6 th, 7 th, 15 th, 23 rd and 24 th bits are different, so that it can be determined that the hamming distance between the hash value of the target work and the hash value of another work is 5. If the preset Hamming distance is 6 at this time, since the Hamming distance between the Hamming value of the target work and the Hamming value of another work is smaller than 6, it can be determined that the Hamming value of the work is similar to the Hamming value of the target work, that is, the work is similar to the target work.

S104, acquiring a first work release image generated by the first release platform when the target work is released, and sending the first work release image to the creator so that the creator signs the first work release image based on a private key of the creator to obtain a first release information ciphertext.

In some possible embodiments, when the first distribution platform distributes the target work, a first work distribution image generated when the first distribution platform distributes the target work may be acquired, where the first work distribution image may include related information of the first distribution platform, related content of the target work, distribution time, related information of an creator, and the like, so as to be used as a distribution certificate of the first distribution platform corresponding to the target work. The first work release image may be a web page screenshot, a public number screenshot, a publishing cover, etc., and may be specifically determined based on an actual application scenario, which is not limited herein. Further, the first work distribution image may be sent to the creator to cause the creator to sign the first work distribution image based on its own private key, and while encrypting the first work distribution image, once the creator signs the first work distribution image, the caption creator approves various information in the first work distribution image, i.e., the creator approves the distribution of the target work by the first distribution platform.

And S105, the first authorization information is sent to the first distribution platform so that the first distribution platform signs the first authorization information based on a private key of the first distribution platform to obtain a first authorization information ciphertext.

In some possible implementations, the first authorization information of the creator may be sent to the first distribution platform to cause the first distribution platform to sign the first authorization information based on its private key, while the first work distribution image is sent to and signed by the creator. The first authorization information is signed, and the first issuing platform approves the relevant regulations of the first authorization information of the creator, so that after both parties approve the relevant information of the other party, authorization confirmation of the first work is completed.

S106, acquiring a first authorization information ciphertext and a first public key of a first distribution platform, acquiring a first distribution information ciphertext and a second public key of an creator, transmitting the first authorization information ciphertext, the first public key, the first distribution information ciphertext and the second public key to a consensus node so that the consensus node verifies the validity of the first authorization information ciphertext and the first distribution information ciphertext, and transmitting a signature confirmation message after verification is passed.

In some possible embodiments, after the signing of the first distribution platform and the creator is completed, an authorization information ciphertext obtained by the first distribution platform after signing the first authorization information and a public key of the first distribution platform may be obtained, and after signing the first work distribution image by the creator is obtained at the same time, the first distribution information ciphertext and the public key of the creator may be obtained. In order to further ensure that the acquired first authorization information ciphertext and the first distribution information ciphertext are valid ciphertexts, and prevent serious influence caused by storing invalid ciphertexts, the authorization information ciphertext, the public key of the first distribution platform, the distribution information ciphertext and the public key of the creator can be sent to the consensus node at the moment, so that the consensus node can verify the validity of the first authorization information ciphertext based on the public key of the first distribution platform and verify the validity of the first distribution information ciphertext based on the public key of the creator respectively. The common node may send a signature confirmation message when the first issuing information ciphertext and the first authorization information ciphertext are both valid ciphertexts, where the signature confirmation message may be any form of information for explaining that the common node considers that the first issuing information ciphertext and the first authorization information ciphertext are both valid ciphertexts, and specific information content is not limited herein. And the signature confirmation message generated by each consensus node can represent the generation node of the signature confirmation message, so that the consensus node sending the signature confirmation message can be determined according to the signature confirmation message after the signature confirmation message of each consensus node is received. Optionally, after generating the signature confirmation message, each consensus node may generate a digest on the signature confirmation message through hash calculation, and encrypt the digest by using its private key to prevent the signature confirmation message from being tampered with.

And S107, receiving the signature confirmation message, storing the first authorization information ciphertext, the first distribution information ciphertext and the hash value of the target work to the blockchain when the signature confirmation message meets a preset consensus strategy, and returning the target block height to the first distribution platform and the creator.

In some possible embodiments, signature verification messages sent by a plurality of consensus nodes in the blockchain may be received, and when each received signature verification message meets a preset consensus policy, it may be determined that both the first distribution information ciphertext and the first authorization information ciphertext are valid ciphertexts. The preset consensus strategy may be that when a certain proportion of consensus nodes in all the consensus nodes in the blockchain confirm that the hash value of the first electronic evidence of the same type is consistent with the hash value of the second electronic evidence, for example, after receiving a signature confirmation message sent by ninety-five percent of the consensus nodes, the first sending information ciphertext and the first authorization information ciphertext may be considered to be valid ciphertexts. Or, the preset consensus strategy may also be that when receiving signature confirmation messages sent by a plurality of consensus nodes in the blockchain, whether the consensus node sending the signature confirmation message belongs to the preset consensus node is determined based on the signature in the signature confirmation message, and/or after the consensus node sending the signature confirmation message is the preset consensus node and/or the consensus node sending the signature confirmation message exceeds all the consensus nodes in the blockchain by a certain proportion, the first distribution information ciphertext and the first authorization information ciphertext are considered to be valid ciphertexts. It should be specifically noted that the preset consensus policy may further include, but is not limited to, a Proof of Work (PoW), a Proof of equity (PoS), a share authorization (Delegated Proof of Stake, DPoS) and a practical barking mechanism (Practical Byzantine Fault Tolerance, PBFT), and a risple consensus algorithm, which may be specifically determined based on the actual application scenario, and is not limited herein.

Further, the first authorization information ciphertext, the first distribution information ciphertext, and the hash value of the target work may be packaged into a block, and the block height of the block may be used as a target block height to be sent to the first distribution platform and the creator, so that the first distribution platform and the creator determine a target block storing the first authorization information ciphertext, the first distribution information ciphertext, and the hash value of the target work from the blockchain based on the target block height. The specific implementation manner in which the first authorization information ciphertext, the first distribution information ciphertext, and the hash value of the target work are included in the block may be determined based on an actual application scenario, which is not limited herein.

Referring to fig. 7, fig. 7 is another flow chart of a work management method according to an embodiment of the present application. The work management method shown in fig. 7 may include the following steps S201 to S206.

S201, receiving an authorization change request submitted by an creator.

In some possible implementations, when the creator wants to terminate the publication rights of the first publication platform to the target work and give the second publication platform publication rights to the target work, the creator may submit an authorization change request to change the authorization object. The authorization change request submitted by the creator may carry second authorization information and a target block height, where the second authorization information includes a target work, a second authorization object, and a second authorization period. Further, the blockchain may receive an authorization change request submitted by an author and determine whether to complete the authorization change based on the authorization change request.

S202, determining a target block from a block chain based on the block height, and acquiring a first authorization information ciphertext corresponding to the target work and a hash value of the target work from the target block.

In some possible embodiments, when the authorization change request carries the target block height, a target block corresponding to the target block height may be determined from the blockchain, and the first authorization information ciphertext corresponding to the target work and the hash value of the target work may be obtained from the target block. Specifically, the block body of the target block may be parsed to determine the hash value of the target block and the first authorization information ciphertext from the hash value of the root node of the obtained merck tree, the block body of the target block may be parsed to determine the hash value of the target block and the first authorization information ciphertext from the merck tree of the block body, the determination mode of the hash value stored in the target block may be determined, and the hash value of the target work may be obtained by performing hash calculation on the target work in the same hash determination mode, where the specific acquisition mode may be determined based on the actual application scenario, and the present invention is not limited thereto.

S203, decrypting the first authorization information ciphertext based on the first public key to obtain the first authorization information.

In some possible embodiments, since the first authorization information ciphertext is obtained by signing the first authorization information by the first distribution platform and the first authorization information is already approved by the first distribution platform, in order to determine the validity of the second authorization information carried in the authorization change request, the first authorization information that has been signed by the first distribution platform needs to be compared with the second authorization information, so as to avoid unfairness caused by comparing the first authorization information that is retransmitted by the creator. Therefore, the public key of the first distribution platform can be obtained, the first authorization information can be obtained by decrypting the first authorization information based on the public key of the first distribution platform, and the authorization change request of the creator is allowed by the first distribution platform in a lateral description.

S204, when the second authorization period is after the first authorization period in the first authorization information and the submitting time of the authorization change request is outside the first authorization period, acquiring a second work release image of the target work on a second release platform corresponding to the second authorization object information.

In some possible embodiments, the first authorization period in the first authorization information is compared with the second authorization information in the second authorization information, if the second authorization period is before the first authorization period, the second authorization period is indicated as an error period or an expiration period, and then the second authorization information is determined as invalid information, and then the authorization change request of the response creator is refused. On the other hand, if the first authorization period and the second authorization period have time intersection, the first distribution platform still has the distribution right of the target work at the moment, an authorization change notification can be sent to the first distribution platform at the moment, the second work distribution image of the second distribution platform is determined after the first distribution platform agrees to the authorization change, and otherwise, the authorization change request of the creator is refused. If the second authorization period is after the first authorization period and the second authorization period and the first authorization period have no time intersection, the first distribution platform is not entitled to the distribution right of the target work, and the first distribution platform can be not required to be notified to directly determine the second work distribution image of the second distribution platform.

S205, determining a second release information ciphertext based on the second work release image, and determining a second authorization information ciphertext based on the second authorization information.

In some possible embodiments, after determining the second work distribution image generated by the second distribution platform when the target work is distributed, determining the second distribution information ciphertext based on the second work distribution image, and further determining the specific implementation manner of the second authorization information ciphertext based on the second authorization information may refer to the implementation manner shown in step S104 and step S105 in fig. 2, which is not described herein again.

S206, deleting the first release information ciphertext, the first authorization information ciphertext and the hash value of the target block from the target block, and storing the second release information ciphertext, the second authorization information ciphertext and the hash value of the target block into a new block of the blockchain.

In some possible embodiments, since the creator changes the publishing rights of the target work from the first publishing platform to the second publishing platform, it is necessary to delete the first publishing information ciphertext, the first authorization information ciphertext, and the hash value of the target work generated when the first publishing platform publishes the target work from the target block. And storing the hash value, the second release information ciphertext and the second release information ciphertext of the target work into a new block in the block chain after the second release platform releases the target work, and simultaneously returning the block height of the new block to the second release platform and the creator.

Referring to fig. 8, fig. 8 is a schematic flow chart of a work management method according to an embodiment of the present application. The work management method shown in fig. 8 may include the following steps S301 to S303.

S301, receiving an infringement determination request of the first distribution platform.

In some possible implementations, when the first distribution platform finds that other works may be similar or identical to the target work that it distributes, the infringing determination request may be submitted to cause the blockchain to determine whether infringing work information included in the infringing determination request is identical or similar to the target work. It should be noted that, the infringing composition carried in the infringing determination request is a composition considered as suspected infringing by the first distribution platform, and the type and content of the specific composition are not limited herein.

S302, determining a target block from a block chain based on the height of the target block, and acquiring a first distribution information ciphertext corresponding to the target work and a hash value of the target work from the target block.

In some possible embodiments, the specific implementation manner of determining the first distribution information ciphertext corresponding to the target work and the hash value of the target work may refer to the implementation manner shown in step S202 in fig. 7, which is not described herein again.

S303, determining the hash value of the infringing work, decrypting the first distribution information ciphertext based on the second public key to obtain a first work distribution image and generating infringement notification information based on the first work distribution image when the hash value of the infringement work is consistent with or similar to the hash value of the target work, and sending the infringement notification information to a third distribution platform corresponding to the platform information of the infringement work.

In some possible embodiments, after the hash value of the target work is determined from the target block, hash calculation may be performed on the infringement work by using a hash determination method adopted when the hash value of the target work is stored in the target block, so as to obtain the hash value of the infringement work. If both the infringing article and the target article are image articles, it may be determined whether the infringing article is identical or similar to the target article by determining a similarity of the hash value of the infringing article to the hash value of the target article. Specifically, the number of bits of the hash value of the infringing article and the hash value of the target article that are the same may be determined, and the duty ratio of the same number of bits in the hash value of the infringing article or the hash value of the target article may be determined. When the duty cycle exceeds a preset duty cycle, it may be determined that the infringing article is similar to or the same as the target article. Alternatively, when the infringing composition and the target composition are both a written composition or a video composition, an intelligent contract may be invoked to cause a third party accredited to determine whether the infringing composition is the same as or similar to the target composition.

Further, if the infringing article is the same as or similar to the target article, the first distribution information may be decrypted based on the public key of the creator to obtain a first article distribution image, and infringing notification information may be generated based on the first article distribution image. And meanwhile, the third release platform can be determined based on the platform information of the infringing works carried in the infringing determination request submitted by the first release platform, and infringing notification information is sent to the third release platform. The infringement notification information is any form of notification information for notifying the third distribution platform that the third distribution platform has infringed and includes information related to the infringed work (target work) (related information of the creator, related information of the first distribution platform, distribution time of the target work, etc.), and may be specifically determined based on the actual application scenario, and is not limited herein.
