Description

A method for verifying the authenticity of certified digital assets

This application claims the priority of a Chinese patent application filed with the Chinese Patent Office on July 26, 2019, the application number is 201910684253.8, and the invention title is "a method for verifying the authenticity of digital assets", the entire content of which is incorporated by reference In this application.

Technical field

The embodiments of the application relate to the technical field of digital assets, and in particular to a method for verifying the authenticity of digital assets.

Background technique

The digital asset certification platform, also known as the right confirmation platform, is mainly aimed at confirming the rights of a large number of intellectual works or achievements that have not undergone copyright registration. Its functions are mainly embodied in two aspects: first, to confirm the rights of the registered copyrights, trademarks or patents that have obtained patent certificates; second, to confirm the rights of a large number of unregistered intellectual works or achievements. For intellectual works or achievements that have been confirmed by the digital asset certification platform, they need to be managed by the corresponding platform, that is, the digital asset registration platform. The digital asset registration platform is not only used to store the confirmed digital asset data, It also uses the interface with other business systems to establish contact, so that other systems use the data on the digital asset registration platform to complete corresponding data operations.

In the application scenario of a digital asset registration platform as shown in Figure 1, the digital asset registration platform 2 and various types of terminals 1 (such as fixed terminals and mobile terminals) form a point-to-point connection through the Internet to conduct digital assets. Both parties of the transaction (any buyer or seller) can use different terminals 1 to establish a connection through a client 11 installed on the terminal side to complete the transaction of digital assets. The transaction process of digital assets usually includes multiple links. For example, the two parties involved in the transaction must go through the digital asset entity and negotiation to ensure the smooth completion of the transaction.

When a buyer obtains a digital asset, it cannot ensure that the digital asset entity it obtains is authentic, or that the authentication code and link it obtains corresponds to the real digital asset entity. The reason is that usually the entity obtained by the buyer, It can be provided directly by the seller, or the encrypted entity and public key can be provided together after the seller encrypts the entity, or it can also be provided by the third-party server 3 storing the digital asset entity based on the information provided by the seller. Considering that the seller may provide false entities or information, or the data stored in the third-party server may be attacked or tampered with, it will cause the digital asset entity obtained by the buyer to be an unreal entity. In order to avoid this In this case, the buyer has to verify the authenticity of the received digital asset entity.

The embodiments will be described in detail below, and examples thereof are shown in the accompanying drawings.

The embodiments of this application are applied in the scenario described in FIG. 1. Among them, the client 11 generally refers to any buyer's client that receives certified digital assets.

In different embodiments of this application, the digital asset data to be confirmed sent between the clients can be the sum data packet of the authentication code and the digital asset entity, or only the authentication code, where the digital asset data packet is an encrypted data packet . Wherein, if the form of data packet transmission is adopted, it should be considered that the method also includes the process of the client to package the data and parse the data packet, and the specific process is not limited in this embodiment. It should be noted that the digital signature algorithm used in all embodiments of this application is the same as the algorithm used in authentication. In addition, in some embodiments, the scenario described in FIG. 1 may also include other entities, such as a blockchain network or an agency platform.

Example one

Refer to Fig. 2, which is a flowchart of the first and second embodiments of the method for verifying the authenticity of digital assets provided by this application.

S101: After the client receives the authenticated digital asset data whose authenticity has not been verified, it needs to first send the authenticated digital asset data to the digital asset registration platform; wherein the authenticated digital asset data is data including an authentication code and a digital asset entity Package; In this embodiment, the data package can be an encrypted ciphertext data package plus a public key. At this time, when the client sends the data package to the digital asset registration platform, it needs to send the public key together to decrypt it with the public key The packet.

S102: The digital asset registration platform uses a digital signature algorithm to calculate the hash value A of the digital asset entity, and extracts the hash value B stored in the authentication abstract corresponding to the authentication code in the digital asset registration platform, and uses the The value B verifies the hash value A.

In step S102, the digital signature algorithm is used to calculate the hash value A for the entity part of the data packet, and then the digital asset registration platform queries the corresponding authentication summary stored in the platform according to the received authentication code, and extracts The hash value B stored in the authentication digest is compared with the hash value A and the hash value B, specifically to compare whether the two are exactly the same or have a preset specific relationship, for example, if the hash value A and the hash value If the value B is exactly the same, the comparison result obtained is that the verification is successful, and the authentication code and its corresponding entity part are true and effective. Otherwise, if the verification fails, the entity part corresponding to the authentication code is false. Among them, the authentication summary maintained by the digital asset registration platform is the original data generated during the digital asset authentication process, which has authenticity. Therefore, the authenticity of the digital asset entity can be learned through the comparative verification operation in this step.

S103: The digital asset registration platform feeds back the verification result to the client.

In this embodiment, the verification result may be a piece of feedback information to notify the client that the unverified digital asset data received is true or false; in addition, the verification result may also include other content, for example, Verification documents attached to the registration platform-such as an electronic certificate, which records the verification time, the comparison result of the hash value A/B, etc.

S104: The client determines whether the authentic digital asset is obtained according to the verification result.

When the client receives the verification result, if the verification result is shown as a real digital asset entity, the real digital asset entity can be parsed, encrypted, saved, and downloaded on the client; if the verification result is displayed as false For the digital asset entity, the client can delete or return the data packet containing the false digital asset entity to the seller's client, and feedback the verification failure information to the seller's client, thereby terminating the transaction.

It can be seen from the above technical solutions that the method provided in this application uses the digital asset registration platform to extract authentic hash values to verify the authenticity of the digital asset entity received by the client, so that the client can confirm the received digital asset entity Whether it is a real entity, and perform corresponding operations on real or false entities to ensure the effective conduct of digital asset transactions.

It should be pointed out that in this embodiment and subsequent examples, the calculation of the hash value can be based on the digital asset entity, or can be based on the data packet or digital asset that includes the digital asset entity, depending on the system settings. Therefore, one of them will be used as an example in the following examples.
