Detailed Description
To make the objects, technical solutions and advantages of the exemplary embodiments of the present application clearer, the technical solutions in the exemplary embodiments of the present application will be clearly and completely described below with reference to the drawings in the exemplary embodiments of the present application, and it is obvious that the described exemplary embodiments are only a part of the embodiments of the present application, but not all the embodiments.
The first embodiment is as follows:
to solve the technical problem in the prior art, the embodiment of the present application shows a digital asset finance system, which can specifically refer to fig. 3, and the system includes: the system comprises a client 1 and a digital asset financial platform 2, wherein the digital asset financial platform comprises: a digital asset certification platform 21 connected with the output end of the client 1, a digital asset registration platform 22 connected with the output end of the digital asset certification platform 21, a digital asset package processing platform 23 connected with the output end of the digital asset registration platform 22, and a financial center platform 24 connected with the output end of the digital asset package processing platform 23. The digital asset finance platform 2 further includes: and the blockchain agent platform 25, wherein the blockchain agent platform 25 is respectively connected with the client 1, the digital asset certification platform 21, the digital asset registration platform 22, the digital asset pack processing platform 23 and the financial center platform 24.
The blockchain agent platform 25 is configured to receive data uploaded by the client 1, the digital asset certification platform 21, the digital asset registration platform 22, the digital asset package processing platform 23, and the financial center platform 24, and send the data to a blockchain network; and is also used for sending the data stored in the blockchain network to the client 1, the digital asset certification platform 21, the digital asset registration platform 22, the digital asset package processing platform 23 and the financial center platform 24.
The client 1 shown in the present application is installed in a terminal, and the client may be a computer, a mobile phone, a tablet computer, a laptop computer, a personal digital assistant, a mobile internet device, or a wearable device.
The types of digital assets in the technical solution shown in the embodiment of the present application include: patents, trademarks, copyrights, etc., all exist in the form of digital asset packages in embodiments of the present application.
And the digital asset package processing platform 23 is used for classifying and packaging the authenticated digital assets stored in the digital asset registration platform 22 according to actual requirements. Taking a patent as an example, the digital asset pack processing platform 23 can pack the patent of patent a, which is the same source, or the patent of a competitor, to generate an asset pack.
The client 1 is used for sending the digital assets to the digital asset finance platform 2 and uploading the digital assets to a block chain network, wherein the block chain network comprises a public chain and a sub chain. It should be noted that the digital asset sent by the client to the blockchain according to the technical solution shown in the embodiment of the present application includes an abstract portion and an entity portion, where the abstract portion is sent to the public chain and the entity portion is sent to the corresponding target sub-chain.
The client is also used for conducting transactions with a digital asset registration platform 22, a digital asset package processing platform 23 and a financial center platform 24 in the digital asset financial platform 2.
The process of trading between a client and the digital asset registry 22 is described in detail below with specific examples.
Example 1:
after negotiation before transaction, the first client sends digital asset data to be confirmed to the second client; the digital asset data to be confirmed is a data packet comprising an authentication code and a digital asset entity; in this embodiment, the data packet may be in a form of an encrypted ciphertext data packet plus a public key, and at this time, when the first client sends the data packet to the second client, in order to enable the second client to check the data included in the data packet, the public key needs to be sent together while sending the data packet, so as to decrypt the data packet through the public key. In this step, the authenticity of the certified digital asset has not been confirmed.
The second client sends the obtained digital asset data to be confirmed to a digital asset registration platform;
in this embodiment, after receiving the digital asset data to be confirmed sent by the first client, if the authenticity of the data in the data packet needs to be checked, the second client may extract the authentication code or the entity part thereof by performing an operation (e.g., parsing) on the received data packet, and then send the authentication code and the entity part to the digital asset registration platform, respectively; if the data does not need to be viewed temporarily, the data packet can be directly forwarded to a digital asset registration platform, and the platform performs further operations (such as analysis and subsequent calculation) on the data packet; meanwhile, because the second client temporarily stores the content of the data packet (entity part) at this time, if the subsequent authentication result is a real entity, the stored data packet can be determined to be real data, and the user can immediately acquire the real entity part from the second client.
The digital asset registration platform calculates a hash value A of a digital asset entity by adopting a digital signature algorithm, extracts a hash value B in an authentication abstract corresponding to the authentication code stored in the digital asset registration platform, and compares the hash value A with the hash value B;
specifically, the digital asset registration platform calculates a hash value a from an authentication code or an entity portion in a data packet by using a digital signature algorithm, then the digital asset registration platform queries a corresponding authentication digest stored in the platform according to the received authentication code, extracts a hash value B stored in the authentication digest, and compares the hash value a with the hash value B, specifically, whether the hash value a and the hash value B are completely the same or have a preset specific relationship, for example, if the hash value a and the hash value B are completely the same, the obtained comparison result is that authentication is successful, the entity portion corresponding to the authentication code is true and valid, otherwise, the authentication is failed, and the entity portion corresponding to the authentication code is false content. The authentication abstract kept by the digital asset registration platform is original data generated in the digital asset authentication process and has authenticity, so that the authenticity of a digital asset entity can be acquired through the comparison operation in the step.
The digital asset registration platform feeds the comparison result back to the second client;
in this embodiment, the comparison result may be a piece of feedback information to notify the second client that the received digital asset data to be confirmed is real or false content; in addition, the comparison result may also include other content, such as an authentication certificate attached by the digital asset registration platform. For example, an electronic certificate of authentication, a description of the authentication time, the result of comparison of the hash values a/B, and the like.
And the second client determines whether to acquire the real digital asset entity according to the comparison result.
After the second client receives the comparison result, if the comparison result shows that the digital asset entity is real, the real digital asset entity can be analyzed, encrypted, stored, downloaded and the like on the second client; if the comparison result shows that the digital asset entity is false, the data packet containing the false digital asset entity can be deleted or returned to the first client by the second client, and the information of failure of confirmation is fed back to the first client, so that the continuation of the transaction is terminated.
According to the technical scheme, the block chain network has the characteristics of decentralization, tamper resistance and repudiation resistance, and data uploaded by a client, a digital asset certification platform, a digital asset registration platform and a digital asset package processing platform are uploaded to the block chain network through a block chain agent platform, wherein the data can be guaranteed not to be tampered, the reliability of digital asset data is guaranteed, and meanwhile the data can be guaranteed to be recorded in time.
Example 2:
in the above embodiment 1, the second client needs to acquire the digital asset data to be confirmed from the first client, and then transfer the data to the digital asset registration platform for processing, and in addition, the second client can obtain the real authenticated digital asset in a manner that the first client directly transmits the digital asset data to be confirmed to the digital asset registration platform.
Example 3:
the difference between this embodiment and embodiment 2 is that in the first embodiment, the hash value calculation and comparison process is completed through the digital asset registration platform, and when a third-party server exists in the system, the digital asset registration platform and the third-party server can send a request to acquire the calculated hash value.
Example 4:
different from embodiment 3, in the system for implementing the method, in addition to being obtained by the third-party server, the digital asset entity may also be obtained by establishing a connection between the digital asset registration platform and a public link node or a child link node of the block link network, where the public link node or the child link node can perform the same function as the third-party server.
Example 5:
the difference from embodiment 3 is that since the entity part in the digital asset data to be confirmed can be stored by the third party server, only the authentication code can be transmitted when the first client transmits the digital asset data to be confirmed to the second client.
According to the technical scheme, the block chain network has the characteristics of decentralization, tamper resistance and repudiation resistance, and data uploaded by a client, a digital asset certification platform, a digital asset registration platform and a digital asset package processing platform are uploaded to the block chain network through a block chain agent platform, wherein the data can be guaranteed not to be tampered, the reliability of digital asset data is guaranteed, and meanwhile the data can be guaranteed to be recorded in time. Meanwhile, the block network can transmit data to the client, the digital asset certification platform, the digital asset registration platform, the digital asset package processing platform and the financial center platform according to the request of the client, the digital asset certification platform, the digital asset registration platform, the digital asset package processing platform and the financial center platform.
Example two:
for flexibility of transaction, the technical solution shown in the embodiment of the present application may split the asset package. Specifically, referring to fig. 4, in an embodiment, the financial center platform 24 in the system includes: a digital asset integrity/decommissioning trading platform 241; one end of the digital asset integration/disassembly transaction platform 241 is connected with the output end of the digital asset pack processing platform 23, and the other end of the digital asset integration/disassembly transaction platform 241 is connected with the output end of the blockchain agent platform 25;
the digital asset integral/split trading platform 241 is used for judging whether the asset pack is an integral trading asset or a local trading asset; and if the assets are locally traded, splitting the asset pack into a plurality of sub asset packs.
In the technical solution shown in the embodiment of the present application, the whole transaction asset refers to a digital asset that is licensed and transferred in a whole manner.
Locally transacting assets, parts of a digital asset being dependent on each other, i.e. a numerical asset which as a whole cannot be split into separate parts.
The following describes the entire transaction asset or the partial transaction asset in detail by using a specific example.
(1) Trademarks (mental trade items);
A. the appropriate transaction is: overall, all of its rights are transferred to the assignee in a licensed or assigned manner.
B. Unsuitable trade: splitting and portioning mode
(2) Copyright (trade in the substance category);
A. (ii) a suitable transaction; overall mode, permission and transfer;
B. in some embodiments: the works are dependent on each other, namely the works can not be divided into independent parts as a whole, and the rights of the works are mostly implementation-class rights and are suitable for trade by shares, such as copy rights, distribution rights, rent rights, exhibition rights, showing rights, broadcast circles, performance rights, transmission rights and the like. For the rights of the independent, separately implementable, combined classes, it may be appropriate to split the deal, for example, a concert contract containing the right to show, advertise, propagate, etc., by splitting the deal of its content, one receiver of the contract is evolved into multiple receivers (deal objects).
(3) Patents (trade-offs in specific material categories);
A. the appropriate transaction is: overall, licensing, and transfer (in two categories, formal and substantive, the former referring to the transfer rights themselves, and the latter including other matters negotiated between them, such as accompanying assets, patent implementation related technologies and devices, market information, and other related matters).
B. Special transactions: the patent resource package with feasibility of implementation and certain market share is traded according to shares; the patent asset pack is divided for trading or securitized for trading.
Example three:
in the system shown in the second embodiment, the financial center platform 24 further includes: digital asset securitization platform 242; specifically, referring to fig. 5, one end of the digital asset securitization platform 242 is connected to the output end of the digital asset pack processing platform 23, and the other end of the digital asset securitization platform 242 is connected to the output end of the blockchain agent platform 25;
a digital asset securitization platform 242 for determining asset package trading contracts and controlling the process of transferring asset package rights according to said trading contracts.
The technical scheme shown in the embodiment of the application is intended to realize popular trading of digital assets. An asset package trading contract may be determined to implement digital asset securitization.
In particular, in one aspect, identifying an asset package trading contract may overcome some disadvantages of patents that are not conducive to trading, such as uncertainty in association and closeness of patents with their accompanying assets, small probability of patent conflicts between enterprises, and often technical reserves in enterprises. Therefore, with the digital asset securitization platform, it may be necessary to break the boundary between enterprises, i.e. to use "technology" (including patents and technical alliances accompanying assets) as the core of transaction (asset pack), assist in lawsuit threats, transactions caused by the process of formation of alliance members, implementation of production between alliance members, implementation of licensed use of upstream and downstream enterprises to which their technology is applied, etc., and also rely on the whole transaction and the per-share transaction of patents.
On one hand, the method determines the property package trading contract and can break the boundary between enterprises, takes the patent technology resource package as a trading object to realize the patent technology alliance between enterprises and individuals, takes the patent technology resource package as an investment object in a securitization trading mode, and is the behavior of the patent technology trading evolving into mass investment. Compared with the traditional stock market such as Shanghai, Shenzhen and the like, enterprises are used as investment main bodies, technical alliances of the enterprises are used as the investment main bodies, the competition relationship of some enterprises can be favorably developed into a cooperative relationship, competition among different alliances can be possibly generated, the problem that the capital is dead in the beginning of excellent technology research and development due to the defects of capital, market, personnel and the like is solved, investment waste is favorably reduced, and the capital can be more efficiently served for entity enterprises in the environment with low risk and strong profit capacity of capital natural buildings.
Example four:

Example six:
in the technical solution shown in the fifth embodiment, since the partial digital asset entity has a large capacity, which may reach several hundred M or even exceed 1G, the digital asset uploaded to the digital asset certification platform 21 by the client 1 may occupy more transmission resources and storage resources. In addition, the authentication process of the digital assets is based on the online operation of the internet, a large number of digital assets are uploaded randomly from different clients 1, and cannot be matched with the use condition of the network transmission resources of the digital asset certification platform 21, so that the uploading of the digital assets is delayed or the transmission fails. In order to solve the problems in the prior art, embodiments of the present application provide a digital asset processing system to be authenticated.
In order to solve the above problem, the technical solution implemented and shown in the present application further includes a preprocessing platform 3 connected to the output end of the client 1 on the basis of the technical solution shown in the fifth embodiment. Specifically, referring to fig. 8, the system shown in the fifth embodiment further includes a preprocessing platform 28 connected to an output end of the client 1, where an output end of the preprocessing platform is connected to an input end of the digital asset certification platform 21;
the preprocessing platform 28 is configured to receive a digital asset data package sent by a client, perform a digital signature operation on the digital asset data package by using a determined digital signature algorithm, and generate a signature string, where the digital asset data package includes a digital asset entity and a bibliographic item;
the link address of the signature character string, the bibliographic item and the digital asset entity is encrypted by adopting an asymmetric encryption algorithm to generate an encrypted asset data packet; and the system is used for generating the abstract of the asset package to be authenticated according to the encrypted asset data package and the public key and uploading the abstract to the block chain network and the digital asset certification platform.
It should be noted that, in the technical solution shown in the embodiment of the present application, the data received by the digital asset certification platform 21 is collectively referred to as a digital asset package to be authenticated, and the data transmitted to the digital asset certification platform 21 by the preprocessing platform 3 is also referred to as an asset package digest to be authenticated.
The digital signature algorithm can be determined by pre-negotiation between the client and the digital asset authentication platform. The digital signature algorithm may also be one of a set of algorithm programs provided in advance, and when the client and the digital asset authentication platform transmit the digital asset, the client selects one of the set of algorithm programs and transmits the digital asset authentication platform to notify the digital asset certification platform 21 to use the same digital signature algorithm. It should be noted that the algorithm program set includes a plurality of digital signature algorithms. The digital signature algorithm may be SHA256, SHA384, SHA512, or the like. The digital signature operation may be a Hash operation.
According to the embodiment of the application, the Hash operation is performed on the digital asset data packet by using the digital signature algorithm, and due to the property of the Hash operation, a generated signature character string is a unique value after the Hash operation is performed on the digital asset data packet. For example, the digital signature algorithm uses the SHA256, and the digital asset package performs a Hash operation using the SHA256 to obtain a 256-bit string, which is a unique value. After different digital asset data packets are subjected to Hash operation by using the same digital signature algorithm, the obtained signature character strings are different. Therefore, the signature string may be used to verify the authenticity of the digital asset package.
For example, when buyer a wants to buy a picture, after the picture is converted into digital assets expressed in electronic data form by technical means, a digital asset data packet is obtained, and a digital signature operation is performed by using SHA256 digital signature algorithm to obtain a real signature character string, wherein the signature character string is unique. Seller B claims to own the picture, and after the picture shown by seller B is converted into a digital asset data packet, the digital signature operation is carried out by using the SHA256 digital signature algorithm to obtain a group of new signature character strings. At the moment, whether the real signature character string is the same as the new signature character string is judged, and if yes, the seller B is a true owner of the picture; if the pictures are not the same, the picture shown by the seller B is a counterfeit, the seller B is the owner pretending the picture, the seller B is not the true owner of the picture, and therefore the buyer A cannot trade with the seller B. Due to the uniqueness of the signature string, the signature string can verify the authenticity of the digital asset pack.
Encrypting the signature character string and the link address of the digital asset entity by adopting an asymmetric encryption algorithm to generate an encrypted asset data packet;
because the capacity of the digital asset entity may be particularly huge, the link address of the digital asset entity with smaller capacity is adopted as a part of the encrypted asset data packet, and the capacity of the encrypted asset data packet is further reduced.
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 one possible embodiment, the digital asset data package is stored in a client, and in another possible embodiment, the preprocessing platform may include a third party server, and the digital asset data package is stored in the third party server. The digital asset data packet is stored in the third-party server, so that the storage resource of the client occupied by the digital asset data packet can be reduced, and the condition that the client runs at a low speed is avoided.
In the embodiment of the application, the asymmetric encryption algorithm is complex in strength, so that the security is extremely high. The asymmetric encryption algorithm comprises two keys, namely a public key and a private key, wherein the public key and the private key are different keys, and the encrypted asset data packet is obtained by encrypting the signature character string and the link address of the digital asset entity through the private key; in the process of decrypting the encrypted asset data packet, the public key is used, and the public key is used for decrypting the encrypted asset data packet, so that the signature character string in the encrypted asset data packet and the link address of the digital asset entity can be obtained.
And generating an asset package abstract to be authenticated according to the encrypted asset data package and the public key, and uploading the abstract to a block chain agent platform and a digital asset certification platform 21. The block chain agent platform uploads the received data to a block chain network, and the block chain network has the characteristics of decentralization, tamper resistance and repudiation resistance, so that the summary of the asset package to be authenticated, which is composed of the encrypted asset data package and the public key, is uploaded to the block chain network, and the digital asset entity corresponding to the link address of the digital asset entity in the encrypted asset data package can be guaranteed not to be tampered, and can be recorded in time.
The method and the device have the advantages that the abstract of the asset package to be authenticated is uploaded to the digital asset proving platform 21 by the client, the abstract of the asset package to be authenticated is composed of the encrypted asset package and the public key, the encrypted asset package is obtained by encrypting the link address and the signature character string of the digital asset entity with small capacity, and therefore compared with the method that the client directly uploads the digital asset entity to the digital asset proving platform 21, the method and the device upload the abstract of the asset package to be authenticated to the digital asset proving platform 21, and occupied transmission resources and storage resources are greatly reduced.
