Description

A digital asset processing system to be authenticated

This application claims the priority of a Chinese patent application filed with the Chinese Patent Office, the application number is 201910656458.5, and the invention title is "a digital asset processing system to be certified" on July 19, 2019, the entire content of which is incorporated into this application by reference in.

Technical field

This application relates to the technical field of digital assets, in particular to a processing system based on a digital asset to be authenticated.

Background technique

Any intellectual labor results expressed in the form of electronic data can be called digital assets, for example, patents, trademarks and copyrights expressed in the form of electronic data. When digital assets are traded, it is necessary to determine the ownership of the rights to ensure that the digital assets can be disposed of by the provider. The ownership of patents and trademarks is determined by the national administrative department, and copyright rights have been created from the day the author creates the work. If the work is not registered by the relevant national administrative department, there will be disputes over the ownership of the work rights.

In order to avoid the above problems, the digital asset processing system can be used to authenticate the digital assets, that is, to stamp the digital assets with a time stamp to clarify the ownership of the copyright. As shown in Figure 1, the digital asset processing system includes a number of terminals 1 and a digital asset authentication platform 2. The terminal 1 is connected to the digital asset authentication platform 2 via the Internet. Generally, the client terminal 11 can be installed on the terminal 1 to establish a data connection between the client terminal 11 and the digital asset authentication platform 2. Specifically, the digital asset is uploaded to the digital asset authentication platform 2 through the client 11, and the digital asset authentication platform 2 performs an authentication operation on the digital asset.

The digital asset 3 provided by the client 11 usually includes two parts, a description item 31 and a digital asset entity 32, as shown in FIG. 2. Among them, the bibliographic item 31 usually contains the name, address, priority document information, etc. of the right holder; the digital asset entity 32 is usually a collection of various legal and technical documents that record the core content of the digital asset. Due to the huge difference in the capacity of digital assets to be authenticated, for example, the file capacity of film and television works expressed in the form of electronic data is very large, reaching several hundred M or even more than 1G, which makes the digital assets uploaded by the client 11 inevitably occupy more transmission resources And storage resources. In addition, the authentication process of digital assets is an online operation based on the Internet. Obviously, a large number of digital assets are randomly uploaded from different clients, which cannot match the usage status of the network transmission resources of the digital asset authentication platform, which leads to the uploaded digital assets. Delays or transmission failures make the authentication operation untimely.

Detailed ways

In order to make the purpose, technical solutions, and advantages of the present application clearer, the technical solutions of the present application will be described clearly and completely in conjunction with specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of this application. The technical solutions provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

Referring to Figure 1, in the prior art, due to the large physical capacity of some digital assets, which can reach hundreds of M or even more than 1G, the digital assets uploaded by the client 11 to the digital asset authentication platform 2 will occupy more transmission and storage resources. . In addition, the authentication process of digital assets is an online operation based on the Internet. A large number of digital assets are randomly uploaded from different clients 11, which cannot match the usage status of the network transmission resources of the digital asset authentication platform 2, resulting in delays in uploading digital assets or The transmission failed. In order to solve the problems in the prior art, an embodiment of the present application provides a digital asset processing system to be authenticated.

Example 1

The embodiment of the application provides a digital asset processing system to be authenticated. As shown in FIG. 3, the processing system includes a client 11, and a digital asset authentication platform 2 and a blockchain network 4 connected via the Internet;

Wherein, as shown in FIG. 4, the client 11 is configured to perform the following steps:

Specifically, the digital signature algorithm may be determined through pre-negotiation between the client and the digital asset authentication platform. The digital signature algorithm can also be one of a set of pre-provided algorithm programs. When the client and the digital asset authentication platform transmit digital asset data packets, the client selects one of the algorithm programs and sends it to the digital asset authentication platform. , Notify the digital asset authentication platform to use the same digital signature algorithm. It should be noted that the set of algorithm programs includes multiple digital signature algorithms.

The client of this application is installed in a terminal, and the terminal can be a computer, a mobile phone, a tablet computer, a laptop computer, a personal digital assistant, a mobile Internet device, or a wearable device. It should be noted that, no matter what type of digital assets, the types include: patents, trademarks, copyrights, etc., in the embodiments of this application, they all exist in the form of digital asset data packages.

The digital signature algorithm may be SHA256, SHA384 or SHA512. The digital signature operation may be a Hash operation.

The embodiment of the present application uses a digital signature algorithm to perform a hash operation on the digital asset data packet. Due to the nature of the hash operation, after the hash operation is performed on the digital asset data packet, the generated signature string is a unique value. For example, the digital signature algorithm uses SHA256, and the digital asset data packet uses SHA256 to perform a Hash operation to obtain a 256-bit number string, which is a unique value.

After different digital asset data packets use the same digital signature algorithm to perform the Hash operation, the signature strings obtained are all different. Therefore, the signature string can be used to verify the authenticity of the digital asset data package, for example:

When buyer A wants to buy a painting, when the painting is converted into a digital asset expressed in electronic data by technical means, the digital asset data packet is obtained, and the SHA256 digital signature algorithm is used for digital signature operation to obtain the real signature characters String, the signature string is unique. Seller B claims that he owns this painting. When the painting shown by Seller B is converted into a digital asset data packet, it uses the SHA256 digital signature algorithm to perform a digital signature operation to obtain a new signature string. At this point, it is judged whether the real signature string is the same as the new signature string. If they are the same, it means that seller B is the real owner of the painting; if they are not the same, it means that the painting shown by seller B is an imitation, and seller B It is pretending to be the owner of the painting, and seller B is not the true owner of the painting, so buyer A cannot trade with seller B. Due to the uniqueness of the signature string, the signature string can verify the authenticity of the digital asset package.

In a possible implementation manner, the digital asset data package includes digital asset entities and bibliographic items. The digital asset data package that generates the signature string may also include bibliographic items.

Since the capacity of the digital asset entity may be extremely large, this application uses the link address of the digital asset entity with a smaller capacity as a part of the encrypted asset data package, thereby reducing the capacity of the encrypted asset data package.

It should be noted that, according to the link address of the digital asset entity, the storage location of the digital asset entity can be determined. In a possible implementation manner, the digital asset data package is stored in the client. In another possible implementation manner, the processing system further includes a third-party server 5, and the digital asset data package is stored in Third-party server 5.

The digital asset data package is stored in the third-party server 5, which can reduce the storage resources of the client terminal occupied by the digital asset data package, and avoid the situation that the client runs slowly.

In the embodiments of the present application, the asymmetric encryption algorithm has complex algorithm strength, so the security is extremely high. Asymmetric encryption algorithm has two keys, including public key and private key. The public key and private key are two different keys. The signature string and the link address of the digital asset entity are encrypted by the private key to obtain encrypted asset data. Package: In the process of decrypting the encrypted asset data package, the public key is used. The public key decrypts the encrypted asset data package to obtain the signature string in the encrypted asset data package and the link address of the digital asset entity.

According to the encrypted asset data package and public key, a summary of the asset package to be authenticated is generated and uploaded to the blockchain network 4 and the digital asset authentication platform 2.

Specifically, the blockchain network has the characteristics of decentralization, tamper-proof and non-repudiation, so uploading the encrypted asset data package and the public key to be certified asset package summary to the blockchain network can ensure that the encrypted asset data package The digital asset entity corresponding to the link address of the digital asset entity will not be tampered with and will be recorded in time.

In a possible implementation manner, the system further includes: a platform database 6 configured on the Internet;

Referring to Figure 5, the digital asset authentication platform 2 is configured to perform the following steps:

Upload the certified asset package to the blockchain network 4 and the platform database 6.

The platform database 6 is configured to perform the step of: receiving the certified asset package.

The specific process of reviewing the digital asset data package corresponding to the asset package summary to be certified is: decrypt the asset package summary to be certified with the public key to obtain the signature string and the link address of the digital asset entity, and determine the number according to the link address of the digital asset entity The asset entity performs a digital signature operation on the digital asset data packet composed of the newly obtained digital asset entity to obtain a new signature string, and compare the decrypted signature string with the new signature string. If they are consistent, review by. After the audit is passed, the time stamp and authentication code of the digital asset data package are generated, and the authentication asset package with the time stamp and authentication code is generated.

Take an example to illustrate: when the user completes a picture, the picture is processed by the client to obtain a summary of the asset package to be authenticated. Upload the summary of the asset package to be certified to the digital asset certification platform. The digital asset certification platform uses the public key to decrypt the encrypted asset data package to obtain the signature string and the link address of the digital asset entity. The picture is determined by the link address of the digital asset entity The corresponding digital asset entity performs a digital signature operation on the digital asset data packet formed by the digital asset entity corresponding to the link address of the digital asset entity to obtain a new signature string. Compare whether the signature string obtained by decrypting the encrypted asset data packet is consistent with the new signature string. If they are consistent, the verification is passed, the time stamp and authentication code of the digital asset entity are generated, and the authentication asset with the time stamp and authentication code is generated package. In the embodiment of the application, the time stamp can be used to prove the upload time of the painting, which indirectly explains the creation time of the painting completed by the user, and provides evidence to prove the copyright ownership of the painting. The authentication code can play a role in confirming the authentication asset package.

Upload the certified asset package with the time stamp and the certification code to the blockchain network to record the certified asset package. In addition, the certified asset package can also be uploaded to the platform database 6 for storing the certified asset package.

In a possible implementation manner, the processing system further includes: a preprocessing platform 7 and a platform database 6 configured on the Internet, as shown in FIG. 6.

Platform database 6 and digital asset certification platform 2;

It should be noted that since a large number of asset package abstracts to be certified are uploaded to the digital asset certification platform, if all of them pass the digital asset certification platform certification, it will cause a large amount of data to be certified by the digital asset certification platform, and the digital asset certification platform will have a heavy load. In the embodiment of this application, the preprocessing platform is used to replace the digital asset authentication platform to complete the operation of generating the time stamp, so that the digital asset authentication platform only receives the quasi-authenticated asset package with the time stamp, which can reduce the workload of the digital asset authentication platform. Speed up the operation of the digital asset certification platform.

The digital asset authentication platform 2 is further configured to execute the following steps:

Receive the quasi-certified asset package and generate the certification code;

According to the authentication code and the quasi-certified asset package, a certified asset package is generated, and the certified asset package is uploaded to the blockchain network 4 and the platform database 6.

The platform database 6 is configured to perform the steps of: receiving a quasi-certified asset package, and receiving a certified asset package.

In this embodiment of the application, a preprocessing platform is used instead of a digital asset authentication platform to complete the operation of generating a quasi-authenticated asset package with a time stamp.
