[0054] The present application will be described below with reference to the accompanying drawings in the present application.

[0055] Embodiment 1: As Figure 1 shown, a method for data collection and protection of ceramic digital copyrights of the present invention specifically includes the following steps:

[0056] S1. Obtain the image data, identity certificate information, and production process data of the ceramic work; the image data includes the appearance, texture, color, and three-dimensional structure of the ceramic work; the identity certificate information includes the creation time, author, material, and process of the ceramic work; the production process data includes raw material ratio, ceramic forming, and firing parameters;

[0057] Image data collection: Use a high-resolution digital camera or professional scanner to ensure that fine texture and color changes can be captured;

[0058] Appearance recording: Adopt high-resolution photography or scanning technology to photograph the ceramic work comprehensively and from multiple angles to ensure that the overall shape, detailed texture, color matching, and any unique decorative elements of the work can be clearly shown; Use professional software to perform post-processing on the image to ensure color restoration and detail clarity, so as to accurately reflect the original appearance of the work;

[0059] Texture and color analysis: Use image processing technology to analyze the texture and color of the ceramic surface and extract feature data, which helps to make accurate comparisons during anti-counterfeiting verification;

[0060] Three-dimensional structure: For ceramic works with complex structures or special three-dimensional effects, their three-dimensional models can be reconstructed through 3D scanning technology to digitally preserve the spatial form of the work completely;

[0061] Identity certificate information is obtained by directly asking the author or manufacturer, or by consulting relevant archives and certification documents;

[0062] Creation time: Record the creation time of the ceramic work to ensure that the history and origin of the work can be accurately traced later;

[0063] Author: Record the creator information of the ceramic work in detail, including name, possible stage name, or other relevant identity information;

[0064] Materials and Techniques: Accurately record the types of materials used in the ceramic work and their proportions, as well as the specific technological steps in the production process of the work; this information is very important for determining the technical style and production techniques of the work;

[0065] For production process data, it is necessary to communicate with the manufacturer or craftsman to ensure obtaining the most accurate production process parameters;

[0066] Raw Material Proportions: Record the proportions of the raw materials used in the production of the ceramic work, which directly affect the physical and chemical properties of the work;

[0067] Ceramic Forming and Firing Parameters: Describe in detail the specific technological parameters used in each stage of ceramic production, such as forming techniques, firing temperature and time, etc.;

[0068] By comprehensively collecting and recording these data, it can provide a reliable basis for subsequent anti-counterfeiting processing, blockchain registration and copyright database construction, thereby effectively protecting the copyright of ceramic art works and the legitimate rights and interests of the creators.

[0069] S2. Conduct anti-counterfeiting processing on the image data by embedding digital watermarks in the image data of the ceramic work; the digital watermarks include author information and work numbers;

[0070] Digital watermark technology is a technology for embedding invisible or hardly perceptible information into multimedia data. This information can be text, image or code, used to prove the source, ownership or integrity of the data; for ceramic works, the embedding of digital watermarks needs to meet two core requirements: one is that the watermark should be sufficiently hidden without affecting the aesthetic experience of the work; the other is that the watermark must have high robustness, that is, it is difficult to be removed or tampered with, ensuring the copyright protection of the work during digital dissemination;

[0071] According to the characteristics of the work, design digital watermarks containing author information and work numbers; the watermark design needs to consider the balance between concealment and robustness to ensure that the watermark can resist common image processing operations without affecting the visual effect of the work;

[0072] Adopt advanced digital watermark embedding algorithms, such as spread steganography, transform domain watermarking techniques (such as DCT, DWT) or deep learning algorithms, to embed the designed watermark information into the image data of the ceramic work; the selected algorithm needs to consider its adaptability under the complex textures and color changes of the ceramic work to ensure the invisibility and robustness of the watermark;

[0073] Determine the position of watermark embedding, usually select at the texture details or color changes of the work to ensure that the overall visual perception and artistic expressiveness of the work are not affected after embedding;

[0074] After the embedding is completed, the robustness of the watermarked image data is tested by simulating image processing and attacks under different conditions to ensure that the watermark information can be retained in various possible digital environments. At the same time, a visual quality assessment is carried out to confirm that the presence of the watermark will not have a negative impact on the artistic appreciation of the work.

[0075] Step S2 realizes anti-counterfeiting processing of the image data that is imperceptible and difficult to remove while maintaining the original appearance of the ceramic work. This not only improves the copyright protection level of the ceramic work but also provides technical support for subsequent copyright verification and authenticity identification.

[0076] S3. Register the image data, identity information, and production process data of the ceramic work on the blockchain to obtain a digital document set of the ceramic work.

[0077] As a distributed ledger technology, the blockchain is jointly maintained by numerous nodes. Each node stores a complete transaction history record, and once the data is written, it cannot be tampered with, which provides a highly secure and transparent storage environment for the copyright information of the ceramic work. By adding the relevant data of the ceramic work to the blockchain in the form of blocks, the long-term persistence and verifiability of the data can be ensured.

[0078] Pack the processed image data, identity information, production process data, and the image data with digital watermark. This data packet contains the full picture information of the ceramic work, from the appearance to the creation details and then to the anti-counterfeiting marks, forming a comprehensive digital fingerprint.

[0079] On the blockchain platform, create a smart contract for the ceramic work. A smart contract is a computer program that automatically executes, controls, or documents legal events and actions, and can handle behaviors such as copyright registration, transfer, and authorization of the work. The smart contract embeds the metadata of the work, including the author, work number, creation time, etc., to ensure that every copyright-related transaction can be automatically verified and recorded on the blockchain.

[0080] Through the API interface of the blockchain, submit the encapsulated data packet to the blockchain network. This process will trigger a new transaction, adding the copyright information of the ceramic work as a new block to the blockchain. Each block contains the hash value of the previous block, forming an irreversible chain structure to ensure the integrity and immutability of the data.

[0081] Establish and manage a ceramic digital copyright database to ensure data security and access control.

[0082] Encrypt and store the copyright data of the ceramic work to protect the data from unauthorized access and tampering.

[0083] Through the implementation of step S3, a digital copyright archive of ceramic works can be effectively established, ensuring its non-tamperability and traceability throughout the process, thus providing a strong copyright protection mechanism for artists and creators.

[0084] S4. Perform time calibration processing on the digital document set, stamp a time stamp on the digital document set, and obtain the copyright data of the ceramic works;

[0085] The main objectives of time calibration and time stamp stamping are to provide an undeniable proof of the creation time for the copyright data of ceramic works, ensuring the timeliness, authenticity, and verifiability of the data; in the digital age, time stamps can be used as key evidence in the event of copyright disputes.

[0086] Determine a trusted time source as the time reference for the data set. Usually, the Network Time Protocol (NTP) or other recognized time synchronization protocols are adopted;

[0087] Match the digital document set of the ceramic works with this time reference to ensure that the creation time and change time of the data set are consistent with the actual events;

[0088] Using digital signature technology, generate time stamps for each key data item (such as image data, identity proof information, production process data, etc.) in the digital document set; the time stamp contains the exact time when the data item was created or modified, the identity information of the data owner, and the verification data of the digital signature, ensuring the non-forgeability and traceability of the time stamp;

[0089] Attach the obtained time stamps to the digital document set of the ceramic works to form the final copyright data; in this way, each piece of copyright data is bound to an exact creation time, and any subsequent viewing or operation can be traced back to this time point;

[0090] Ensure that each important data item of the ceramic works undergoes time calibration and time stamp processing to guarantee the integrity and non-tamperability of the data set; the time stamp, as part of legal evidence, can be used to prove the creation time and ownership of the data set, providing legal protection for copyright protection;

[0091] Through the implementation of step S4, the digital copyright data set of the ceramic works will have strong time evidence support, providing strong protection and support for artists and creators in the face of copyright infringement and legal disputes.

[0092] S5. Establish a ceramic digital copyright database, set access permissions, and encrypt and store the copyright data of the ceramic works;

[0093] This step aims to create a centralized, secure, and easily manageable storage platform for the copyright information of ceramic works; the purpose is to ensure that data is protected from illegal access, tampering, or leakage, while facilitating legitimate rights holders and authorized institutions to query and verify the copyright information of ceramic works;

[0094] Adopt a distributed database architecture to improve the stability of the system and the reliability of data; the database should be designed to support high-concurrency access so that it can be effectively scaled when demand increases;

[0095] Copyright data needs to be encrypted before storage, using internationally recognized encryption algorithms such as AES (Advanced Encryption Standard), RSA, etc., to ensure that even if the data is illegally accessed, it cannot be directly read; at the same time, implement a higher level of encryption protection for sensitive fields such as author information and work numbers;

[0096] Establish a strict access permission system to ensure that only authenticated users can access the database; including ceramic artists themselves, copyright agencies, law enforcement agencies, etc.; adopt role-based access control to assign corresponding access rights and operation rights to different user groups;

[0097] Regularly back up the database to prevent data loss or damage; the backups should be stored separately in different physical locations to improve disaster recovery capabilities; at the same time, design a data recovery process to ensure that data can be quickly restored in the event of a data loss incident;

[0098] Record all access and modification operations on copyright data, including visitor identity, timestamp, operation type, etc., to provide an audit trail for possible copyright disputes;

[0099] Develop a user-friendly interface for rights holders to query, upload, or update copyright information; at the same time, provide API interfaces to allow third-party applications or systems to integrate, so as to efficiently utilize copyright data within the legal scope

[0100] Step S5 will effectively guarantee the security and manageability of the copyright data of ceramic works, provide a solid foundation for intellectual property protection for artists and creators, and at the same time promote the healthy development of the art market.

[0101] Example two: As Figure 2 shown, a data collection and protection system for the digital copyright of ceramics according to the present invention specifically includes the following modules;

[0102] A data collection module that obtains the image data, identity proof information, and production process data of ceramic works; the image data includes the appearance, texture, color, and three-dimensional structure of ceramic works; the identity proof information includes the creation time, author, material, and process of ceramic works; the production process data includes raw material ratio, ceramic forming, and firing parameters;

[0106] A data encryption storage and access control module that establishes a ceramic digital copyright database, sets access permissions, and encrypts and stores the copyright data of ceramic works.

[0107] Through the anti-counterfeiting processing module, the system embeds creator information and work numbers using digital watermark technology without damaging the visual effect of ceramic works; it not only improves the anti-counterfeiting ability of works, but also makes authenticity identification and attribution confirmation rapid and reliable;

[0108] The blockchain registration module uses the immutability and decentralization characteristics of blockchain technology to create a transparent and traceable record for the full life cycle information of ceramic works; meaning that every link from creation, production to sales can be traced, greatly enhancing the strength and efficiency of copyright protection;

[0109] The time calibration module provides accurate time proof for the digital document set of ceramic works by stamping a time stamp, which helps to quickly resolve potential legal disputes;

[0110] The data encryption storage and access control module ensures the secure storage of the copyright data of ceramic works, preventing unauthorized access and data leakage through encryption technology; at the same time, reasonable access permission settings not only protect data security, but also ensure that legitimate users can conveniently access the required information, promoting the legal dissemination and utilization of works;

[0111] The system integrates a variety of advanced technologies such as data collection, anti-counterfeiting processing, blockchain, time stamping, and encrypted storage, filling the technological gap and providing a comprehensive solution for copyright protection in the field of ceramic art; it not only solves the limitations of traditional copyright protection means, but also promotes the innovation and development of technology in practical applications;

[0112] In summary, through a series of carefully designed functional modules, the system effectively addresses the copyright protection challenges faced by ceramic works in the digital age, creating a safer, more transparent, and fairer creation environment for ceramic artists and creators.
