BACKGROUND
[0002] With a boom of emerging technologies including Internet, big data, artificial intelligence and block chain, the online digital product industries are rapidly developing such as e-books, videos, audio, pictures and security documents. Their online transaction has been soaring year by year. The traditional digital products are restricted in regards to copyright protection, as they are vulnerable to copy, or tamper with. And origins are difficult to trace.
[0003] The current protection for digital products is DRM (Digital Rights Management) technology. DRM protects digital contents by algorithms, and the digital contents may include: eBook, video, audio, pictures and security documents. Although, the DRM technology can definitely provide sufficient security for the copyright of digital media, it requires the combination of the user's decryption key with local computer hardware. Obviously, the user can only get the ordered service on a specific computer in a specific place, which is an obvious shortcoming for this method.
[0004] Block chain technology, as a new decentralized protocol, can safely store digital currency transactions or other data, and the information cannot be forged or tampered with. The transaction confirmation in the block chain is completed by all nodes of the block chain, and its consistency is guaranteed by consensus algorithm. The block chain maintains a public account book, which is visible for any node in the storage block, thus ensuring its security from being forged or tempered with. Rooting from the development of block chain technology, many digital product protection technologies have been derived.
[0005] In which, copyright protection derived from block chain technology is mainly categorized into traceability protection and Non-Fungible Token (NFT). Traceability protection is to protect digital product by using block chain's traceability and tamperability. Non-fungible token generates an NFT from a digital product, and protects it as a unique identity, which protects the distribution of the digital product to a certain extent and improves the efficiency of the distribution. However, because of their openness and transparency, digital products can be easily copied, and copyrights are vulnerable.

Compared with the related art, the embodiment solution of the present disclosure provides a method of generating a digital product with copyright protection, which encrypts and protects the digital product in the form of encrypted NFT. As such, such technical solution improves the copyright and safety of the digital product. Users do not necessarily worry about privacy leakage by sharing data, and the maintenance cost of the industry chain of the digital product is reduced. Therefore sharing of the digital product can be expanded in scale under the copyright protection.
[00120] Referring to Fig. 4, Fig. 4 is a flow diagram showing a method of distributing a digital product according to an exemplary embodiment of the present disclosure. The method of distributing a digital product includes the following operations:
[00121] Operation S201, receiving a calling instruction, calling an asset distribution service in the block chain according to the calling instruction, uploading an asset distribution parameter, and generating a predetermined number of equity tokens;
[00122] where the asset distribution parameters include: hash of encrypted NFT, symbol of equity token, total amount of equity tokens, etc.
[00123] Operation S202, distributing the equity tokens as distributing assets of an encrypted NFT.
[00124] Specifically, there are two distribution methods for the encrypted NFT generated by the aforementioned solution:
[00125] in a general scenario, the generated encrypted NFT itself is a kind of issued asset; in a special scenario where the digital product is of high value and inconvenient to transfer its copyright, the digital product distribution can adopt the solution of the present embodiment. The specific process flows can be shown in Fig. 5, and the solution is implemented as follows:
[00126] when a user needs to distributes a special digital product asset having high value or inconvenient for copyright transfer, the user can call the asset distribution service in the block chain, pass in asset distribution parameters, and generate a certain number of equity tokens, where the asset distribution parameters can include hash of the encrypted NFT, equity token symbols, a total amount of equity tokens, etc.
[00127] Therefore, users have a certain number of equity tokens, which are the assets of the distributed encrypted NFT.
[00128] The equity token is the equity representation of the encrypted NFT and represents the equity interest of the encrypted NFT, and the equity token cannot be modified after being distributed.
[00129] In the present embodiment, through the above solution, the asset distribution service in the block chain is specifically called, and the asset distribution parameters are input to generate a predetermined number of equity tokens. And the equity tokens are distributed as assets of the encrypted NFT. Compared with the related art, the embodiment solution of the present disclosure provides a method of distributing a digital product with copyright protection, which encrypts and protects the digital product in the form of encrypted NFT. The distribution of the digital products are more flexible by directly distributing the NFT or distributing the equity tokens of the NFT. As such, such technical solution improves the copyright and safety of the digital product. Users do not necessarily worry about privacy leakage by sharing data, and the maintenance cost of the industry chain of the digital product is reduced. Therefore sharing of the digital product can be expanded in scale under the copyright protection.
[00130] Referring to Fig. 6, Fig. 6 is a flow diagram showing a method of transferring a digital product according to an exemplary embodiment of the present disclosure. The method of transferring a digital product includes the following operations:
[00131] Operation S301, receiving a transfer instruction for a digital product, where a transfer of the digital product includes: a transfer of an encrypted NFT and/or a transfer of equity tokens of the encrypted NFT.
[00132] Operation S302, transferring the encrypted NFT and/or transferring the equity tokens of the encrypted NFT according to the transfer instruction.
[00133] As to the transfer of encrypted NFT, the specific processing operations can be as follows:
[00134] receiving a payment instruction by a purchasing user for the encrypted NFT;
[00135] triggering a transfer instruction to the encrypted NFT, after the payment instruction is successtully operated, and
[00136] replacing the ownership wallet address of the encrypted NFT with a wallet address of the purchasing user;
[00137] receiving a calling instruction from the purchasing user, calling and executing a modification service of the encrypted NFT key according to the calling instruction, and generating a pair of new data public key and new data private key;
[00138] encrypting the original file of the digital product which is uploaded by the purchasing user through the new data public key to create encrypted data, and taking the encrypted data as NFT metadata, and writing the new data private key into the block chain with the encrypted data as a key.
[00139] As such, the encrypted NFT is transferred by the above solution.
[00140] As to the transfer of the equity tokens of the encrypted NFT, the specific processing operations can be as follows:
[00141] receiving a transfer instruction for the equity tokens of the encrypted NFT; determining whether a current account related to an equity change holds more than 50% of the equity tokens based on the transfer instruction; in response that the current account related to the equity change holds more than 50% of the equity tokens, calling an ownership change service of the encrypted NFT, and determining whether the current account related to the equity change validly holds more than 50% of the equity tokens; in response that the current account related to the equity change validly holds more than 50% of the equity tokens, changing an ownership to the current account related to the equity change; otherwise, failing of the equity change.
[00142] As such, the equity tokens of the encrypted NFT is transferred.
[00143] The following is a detailed explanation of the embodiment.
[00144] Specifically, in the present embodiment, the transfer of the digital product includes the transfer of the digital product itself, namely the transfer of the encrypted NFT and the transfer of the equity tokens.
[00145] The transfer of encrypted NFT includes the following operations:
[00146] at first, the purchasing user pays effective funds to purchase the encrypted NFT,
where the effective funds are the price of the encrypted NFT. Afterwards, the ownership wallet address of the encrypted NFT is changed to the wallet address of the purchasing user.
[00147] Then, when the purchasing user executes a key modification service of the encrypted NFT. A pair of new data public and new data private keys will be generated, and the original file of the original digital product uploaded by the purchasing user will be encrypted with the new data public key to create encrypted data. The encrypted data will be used as NFT metadata. The new data private key will afterwards be written into the block chain with the data encrypted by the purchasing user's public key as a new key.
[00148] The caller of the key modification service is only valid for the ownership wallet address of the encrypted NFT.
[00149] The transfer of the equity tokens of the encrypted NFT includes the following operations:
[00150] the general equity token transfer is actually a transfer of the token owner. An equity change account is maintained, and when the equity change account holds more than 50% of the equity tokens, the owner change service of the encrypted NFT is called. And it is judged whether the equity change account holds more than 50% of equity tokens validly, if so, changing the encrypted NFT owner into an equity change account; otherwise, the owner change service fails.
[00151] The present embodiment implements the transfer of the encrypted NFT and the equity tokens of the encrypted NFT. Compared with the related art, the present disclosure provides a method of transferring and authorizing a digital product with copyright protection, by encrypting and protecting the digital product in the form of encrypted NFT. Together with the transfer and authorized use of digital product, the circulation of digital product in the whole industry line is promoted efficiently, conveniently and safely. The present disclosure improves the copyright and safety of the digital product. Users do not necessarily worry about privacy leakage by sharing data, and the maintenance cost of the industry chain of the digital product is reduced. Therefore sharing of the digital product can be expanded in scale under the copyright protection.
[00152] Referring to Fig. 7, Fig. 7 is a flow diagram showing a method of authorizing a digital product according to an exemplary embodiment of the present disclosure. The method of authorizing a digital product includes the following operations:
[00153] Operation S401, in response to an authorization instruction related to a digital product, determining an authorization mode corresponding to the authorization instruction.
[00154] The authorization mode includes: active authorization and application authorization.
[00155] As to the triggering of active authorization, the owner of the digital product can call the authorization service of the encrypted NFT in the block chain to trigger the authorization instruction for the digital product; and as to the triggering of the application authorization, the applicant of the digital product can call the application authorization service of the encrypted NFT to trigger the authorization instruction for the digital product.
[00156] In practical implementation, in response to the authorization instruction, it is determined that the authorization mode corresponding to the authorization instruction is an active authorization, where the authorization instruction is triggered by an owner of the digital product calling the authorization service of the encrypted NFT, or, in response to the authorization instruction, it is determined that the authorization mode corresponding to the authorization instruction is an application authorization, where the authorization instruction is triggered by an applicant of the digital product calling the authorization service of the encrypted IS NFT.
[00157] Operation S402, calling an authorization service of an encrypted NFT corresponding to the authorization mode and the authorization instruction, determining an authorization list of the encrypted NFT, and authorizing the digital product.
[00158] In response that the authorization mode is the active authorization, a list to be authorized is transmitted and written into the block chain according to the authorization instruction. An active authorization list is then added to the authorization list of the encrypted NFT after the transaction is confirmed, where the active authorization list is a wallet address list in the block chain. A key request service of the encrypted NFT is called based on the wallet address in the authorization list of the encrypted NFT in the block chain, and the data private key of the encrypted NFT is obtained.
[00159] In response that the authorization mode is the application authorization, an encrypted NFT address and an applicant address are uploaded according to the authorization instruction, and an application fee is paid. The encrypted NFT address and the applicant address are then written into the block chain. Afterwards, the calling instruction related to the digital product 1s received, and an application list is inquired and examined, and a result is written into the block chain, where the calling instruction is triggered by the owner of the digital product calling an authorization and approval service of the encrypted NFT, and the result includes whether the examining of the application list is passed. An applicant address is then added into the authorization list of the encrypted NFT, after the transaction is confirmed. An calling instruction from the applicant is called, calling a key request service of the encrypted NFT, to obtain the data private key of the encrypted NFT.
[00160] If the applicant is in the authorization list of the encrypted NFT, the applicant can call the key request service of the encrypted NFT, that is, the applicant is qualified to obtain the data private key of the encrypted NFT. On the contrary, the data private key of the encrypted NFT cannot be validly requested for the applicant who does not in the authorization list.
[00161] The solution is implemented by: receiving an instruction for registration, and calling a wallet service in a block chain to register a wallet account according to the instruction for registration, and obtaining registration information; receiving a calling instruction based on the registration information, calling a generation service of an encrypted NFT in the block chain according to the calling instruction, uploading an original file of the digital product, and obtaining a NFT code.
