DETAILED DESCRIPTION

[0013] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0014] In conjunction with the accompanying drawings, a copyright protection method, a copyright protection device, an electronic device and a readable storage medium provided by the embodiments of the present application are described in detail below through specific embodiments and their application scenarios.

[0015] Figure 1 A copyright protection method provided by an embodiment of the present application is shown. The method can be executed by a terminal. The method includes the following steps: S110: When it is detected that there is digital media content to be protected, determine a copyright protection package corresponding to the digital media content.

[0016] The copyright protection package includes the digital media content embedded with a tracking code, a digital signature corresponding to the digital media content, and a hash value of a copyright transaction statement, and the tracking code and the digital signature are generated based on the attribute information of the super SIM card of the terminal.

[0017] Among them, the digital media content to be protected refers to media works that have not yet undergone copyright registration or other legal protection measures; the tracking code is an identifier used to identify, track and protect the copyright of digital media content; the digital signature is an encryption technology that encrypts the digital media content to verify the authenticity and integrity of the source of information; the copyright transaction statement is used to confirm the copyright ownership of the digital media content.

[0018] In this step, the tracking code and the digital signature are generated based on the attribute information of the super SIM card of the terminal. It is understandable that a super SIM card is a highly secure SIM card that usually integrates a powerful security chip that can resist various forms of physical and logical attacks. Using the attribute information of the super SIM card to generate a digital signature and tracking code can effectively protect data from unauthorized access or tampering, and can effectively prevent malware or physical attackers from obtaining and abusing users' sensitive information.

[0019] At the same time, traditional copyright protection mechanisms require users to actively upload their own works, such as text, pictures, audio or video. However, some users do not actively apply for copyright protection after completing their creation, resulting in the inability to implement effective copyright supervision. Therefore, the copyright protection method provided in the embodiment of the present application can realize automatic copyright protection of digital media content. In an exemplary embodiment, the detection of the existence of digital media content to be protected includes: monitoring the operation log of each media file on the terminal; for each of the media files, when the operation log includes a target operation, determining that the existence of the digital media content to be protected is detected, wherein the digital media content is the media file, and the target operation includes creation, editing, and modification.

[0020] It is understandable that by monitoring the operation logs of each media file on the terminal to track, identify and manage the generation, modification and use of media files, media files that need protection can be discovered in time, thereby enhancing the efficiency and accuracy of copyright protection.

[0021] In another exemplary embodiment, the detection of the existence of digital media content to be protected may further include: performing version control on each media file. That is, a version tag is marked for a media file that has been copyright protected, and the copyright tag is used to indicate that the media file has been copyright protected. In the detection process, only the media files that are not marked with the copyright tag are detected, thereby improving the detection efficiency.

[0022] S120: Sending a copyright protection request to the copyright protection cloud platform using the super SIM card.

[0023] The copyright protection request carries the copyright protection package, and the copyright protection request is used to request protection of the copyright corresponding to the digital media content.

[0024] It is understandable that the Internet allows digital content to be quickly copied, modified and shared. Compared with traditional physical media, digital content can be easily copied and transmitted around the world, thus bringing risks to the copyright owner. Therefore, the online protection mechanism based on the copyright protection cloud platform can provide a faster monitoring and processing mechanism, thereby improving the efficiency of copyright protection. At the same time, the super SIM card is used to send a copyright protection request to the copyright protection cloud platform to request the copyright protection cloud platform to protect the copyright corresponding to the digital media content. The copyright protection cloud platform will protect the digital media content based on the copyright protection package. In this way, when there is a copyright risk, the copyright protection cloud platform will send the risk information directly to the corresponding user terminal, and the user terminal will initiate a super SIM pop-up warning to remind the risk information.

[0025] In an embodiment of the present application, when the existence of digital media content to be protected is detected, a copyright protection package corresponding to the digital media content is determined, wherein the copyright protection package includes the digital media content embedded with a tracking code, the digital signature corresponding to the digital media content, and the hash value of the copyright transaction declaration, and the tracking code and the digital signature are generated based on the attribute information of the super SIM card of the terminal, so that they cannot be accessed by unauthorized devices or users, thereby ensuring the security, concealment and tamper-proofness of the digital signature and the tracking code, thereby achieving the purpose of active copyright confirmation and potential infringement tracing, and finally using the super SIM card to send a copyright protection request to the copyright protection cloud platform, wherein the copyright protection request carries the copyright protection package, and the copyright protection request is used to request protection of the copyright corresponding to the digital media content, so that online protection of the digital media content can be achieved, thereby improving the efficiency and strength of copyright protection.

[0031] Step 2: Encrypt the content feature vector and timestamp respectively to obtain an encrypted feature vector and an encrypted timestamp.

[0032] It is understandable that encryption can ensure the security and integrity of data and prevent the subsequently generated digital signatures from being forged and tampered with.

[0033] Exemplarily, the content feature vector F and the timestamp T are asymmetrically encrypted to obtain an encrypted feature vector and encrypted timestamp , the formula can be:

[0034] in, is the public key, is the system parameter, Is a random number.

[0035] Step 3: Use the SIM card signature private key to sign the encrypted feature vector and the encrypted timestamp to obtain the digital signature.

[0036] It can be understood that using the SIM card signature private key of the super SIM card to perform secondary encryption of the encrypted feature vector and the encrypted timestamp can effectively ensure the security of the digital signature during transmission and prevent middle attacks or illegal tampering of data.

[0037] For example, the SIM card signature private key is used right Sign and get the content signature : .

[0041] in, is the normalized value of the SIM card identifier, is the chaos parameter.

[0042] Step 2: Generate the tracking code based on the random number sequence.

[0043] For example, a random number sequence R is used to generate a tracking code sequence , the formula can be:

[0044] in, is a parameter and can be determined by the content feature vector F. represents the rounding function, It is an XOR operation.

[0045] In another exemplary embodiment, after generating the tracking code, the method further comprises: embedding the tracking code into the digital media content using an embedding algorithm. Exemplarily, the embedding algorithm may be:

[0046] in, is the pixel block coordinate, is a set of candidate embedding positions, determined by a random number sequence R, is the spreading factor.

[0047] S116: Based on the tracking code and the digital signature, determine the hash value of the copyright transaction statement.

[0048] Among them, in an exemplary embodiment, S116 may include: constructing a copyright transaction statement based on the digital signature, the identifier of the copyright owner corresponding to the digital media content and the tracking code; storing the copyright transaction statement in the blockchain network to obtain a hash value of the copyright transaction statement.

[0049] It is understandable that using content signing , Tracking Code The copyright transaction statement tx is constructed with the copyright owner's identifier. For example, the identifier can be the copyright owner's public key PK or public key hash. ,So, , and then submit it to the blockchain network for storage to obtain the hash value of the copyright transaction statement.

[0050] In an exemplary embodiment, Figure 2 Another flowchart of a copyright protection method provided by an embodiment of the present application is shown, which may include the following steps: S210: The user uploads the digital media content to the corresponding database using the target device.

[0051] Among them, the user device can be: a mobile phone terminal with a super SIM card function; the digital media content can be: pictures, short videos, etc.; the database can be: an Internet application cloud server, etc.

[0053] Among them, S220 may include: extracting key features of the media content, and generating a digital signature in combination with information such as timestamp and super SIM card ID, and generating a globally unique tracking code based on a random number seed, and embedding the tracking code invisibly into the digital media content. Finally, submitting the digital signature and tracking code to the blockchain network together to achieve content copyright confirmation and certification.

[0054] S230: Upload the copyright protection package to the copyright protection cloud platform.

[0055] Figure 3 Another copyright protection method provided by an embodiment of the present application is shown. The method can be executed by a copyright protection cloud platform. The method includes the following steps: S310: Receive a copyright protection request sent by a terminal.

[0056] Among them, the copyright protection request is used to request protection of the copyright corresponding to the digital media content, and the copyright protection request carries a copyright protection package, and the copyright protection package includes: the digital media content embedded with a tracking code, the digital signature of the digital media content and the hash value of the copyright transaction statement, the tracking code and the digital signature are generated based on the attribute information of the super SIM card of the terminal, the hash value of the copyright transaction statement is generated based on the copyright transaction statement stored in the blockchain network, and the copyright transaction statement is constructed based on the digital signature corresponding to the digital media content and the tracking code.

[0057] S320: Perform copyright protection on the digital media content based on the copyright protection package.

[0058] In an embodiment of the present application, a copyright protection request is sent by a receiving terminal, wherein the copyright protection request is used to request protection of the copyright corresponding to the digital media content, and the copyright protection request carries a copyright protection package, which includes: digital media content embedded with a tracking code, a digital signature of the digital media content, and a hash value of a copyright transaction statement, the tracking code and the digital signature are generated based on the attribute information of the super SIM card of the terminal, the hash value of the copyright transaction statement is generated based on the copyright transaction statement stored in the blockchain network, and the copyright transaction statement is constructed based on the digital signature and tracking code corresponding to the digital media content, and then based on the copyright protection package, the digital media content is protected from copyright. Since the tracking code and the digital signature are generated based on the attribute information of the super SIM card of the terminal, they cannot be accessed by unauthorized devices or users, thereby ensuring the security, concealment and tamper-proofness of the digital signature and the tracking code, thereby achieving the purpose of active copyright confirmation and potential infringement tracing. At the same time, the online protection mechanism based on the copyright protection cloud platform can provide a faster monitoring and processing mechanism, thereby improving the efficiency and strength of copyright protection.

[0059] In an exemplary embodiment, performing copyright protection on the digital media content based on the copyright protection package may include: acquiring content to be detected; and determining whether the content to be detected infringes upon the digital media content based on the copyright protection package.

[0060] In this embodiment, the copyright protection cloud platform can realize real-time infringement judgment of massive content. That is to say, the copyright protection cloud platform continuously monitors the massive network content (such as pictures, short videos, etc.) of media publishing channels through network crawlers, network monitoring, etc., and performs copyright verification on each network content to determine whether the content to be detected infringes on the digital media content.

[0061] In an exemplary embodiment, judging whether the to-be-detected content infringes upon the digital media content based on the copyright protection package may include the following steps: Step 1: Obtain the hash value of the digital signature corresponding to the content to be detected.

[0062] For example, from the content to be detected Get content fingerprint or digital signature :

[0063] in, represents adaptive blocking, For zonal sampling, is the radial spectrum projection, is Trace transformation, Identifier of the copyright owner.

[0064] Then, based on the extracted digital signature Calculating the hash value :

[0065] in, is a homomorphic hash function, is a random generator, is a large prime number, is the fingerprint dimension. is a dimensional feature vector, representing the digital signature. is a vector No. Component, indicating that the content is in The value of a feature dimension.

[0066] Step 2: Based on the hash value of the copyright transaction statement, obtain the digital signature corresponding to the digital media content from the blockchain network.

[0067] That is, using the copyright statement transaction hash Get the digital signature of the digital media content from the blockchain network, and then calculate the homomorphic hash value in front of the number Among them, the homomorphic hash value The calculation method of refers to the above step 1 and will not be repeated here.

[0068] Step 3: Based on the Hamming distance between the hash value of the digital signature corresponding to the content to be detected and the hash value of the digital signature corresponding to the digital media content, determine whether the content to be detected infringes on the digital media content.

[0069] For example, the distance between two homomorphic hash values ​​is calculated :

[0070] in, is the Hamming distance, is the hash code length, Brackets for Iverson.

[0071] Further, in another exemplary embodiment, the judging whether the content to be detected constitutes an infringement on the digital media content based on the Hamming distance between the hash value of the digital signature corresponding to the content to be detected and the hash value of the digital signature corresponding to the digital media content includes: when the Hamming distance is less than a preset distance, determining that the content to be detected constitutes an infringement on the digital media content.

[0072] Furthermore, after determining that the content to be detected constitutes an infringement on the digital media content, the method also includes: obtaining a tracking code corresponding to the content to be detected; and constructing a propagation chain for the digital media content based on the tracking code corresponding to the content to be detected and a content signature library corresponding to the content to be detected.

[0073] It is understandable that after determining that the content to be detected infringes on the digital media content, the digital media content has been embedded with a tracking code during copyright protection, so the tracking code also exists in the content to be detected. Therefore, the tracking code hidden in the content to be detected can be extracted, and then the propagation path can be determined based on the tracking code.

[0074] In an exemplary embodiment, the obtaining of the tracking code corresponding to the content to be detected includes: using a clustering algorithm to determine the tracking code corresponding to the content to be detected based on pixels included in the content to be detected.

[0075] In other words, the content to be detected All pixels are considered as points in two-dimensional space, that is, a set of positions , using clustering algorithm to divide it into two categories, corresponding to and . Using K-means, GMM and other clustering algorithms, It is divided into and Two classes. Calculate the center of two classes and , and the distance from each sample point to the two centers and .

[0076] Finally, a decision is made based on the distance ratio and the tracking code is obtained. :

[0077] in, is the decision threshold, which can be adjusted according to the clustering effect. For content Pixel block coordinates, A collection of locations.

[0078] Then, using the Verifiable Random Function (VRF) and zero-knowledge proof protocol, Verify the propagation chain information in plain text:

[0079] here For the The hash commitment of the hop propagation node, For VRF certification, is a multi-hash verification function. Zero-knowledge proof protocol. Propagation chain evidence Is an ordered tuple consisting of hash commitments from multiple nodes and zero-knowledge proof Combined in the order of propagation.

[0080] Further, after determining that the to-be-detected content infringes upon the digital media content, the method further includes: initiating a super SIM pop-up window warning to the terminal based on copyright risk information corresponding to the digital media content.

[0081] In an exemplary embodiment, Figure 4 Another flowchart of a copyright protection method provided by an embodiment of the present application is shown, which may include the following steps: S410: Using an infringing content discovery algorithm based on a fingerprint library, actively monitor the content to be detected for infringement.

[0082] S420: Integrate the characteristic values ​​of the infringing content.

[0083] S430: Send to the user terminal.

[0084] S440: The Super SIM pop-up window warns the user whether to take legal action.

[0085] S450: When the user decides to conduct legal rights protection, the legal rights protection process is automatically triggered.

[0086] It is understandable that the copyright protection cloud platform continuously monitors the massive network content (such as pictures, short videos, etc.) of media release channels through technical means such as web crawlers and network monitoring, extracts multimedia content fingerprint features, and then conducts copyright verification. When there is a copyright risk in the verification, the cloud platform will send the information directly to the corresponding user's mobile terminal, and the mobile terminal will initiate a super SIM pop-up warning. The user confirms whether to start the copyright protection process according to the needs. The system automatically generates a standardized rights protection notice letter, which is sent to the relevant responsible party of the media release channel after confirmation by the user, requiring it to delete the infringing content. At the same time, the infringement evidence is stored on the blockchain, and through channels such as the judicial chain, it is connected to the notary office, arbitration agency or court to start the legal rights protection process.
