Description

Signature verification method and signature verification machine for meta universe three-dimensional digital model
Technical Field
The invention relates to the technical field of metauniverse, in particular to a signature verification method and a signature verification machine for a metauniverse three-dimensional digital model.
Background
The meta universe is a virtual scene built up from three-dimensional digital models. The virtual scene can be accessed by one or more persons, and the access can realize interaction between persons or interaction between persons and models or between models. Humans in the metauniverse can perform activities (interactions, communications, browsing, etc.) in the metauniverse through projections or three-dimensional digital models.
A meta-universe is made up of one or more virtual scenes, any virtual scene being accessible. There may be an association between virtual scenes (access to additional virtual scenes directly in the virtual scenes to effect scene transition or jump) or no association (access to addresses of additional virtual scenes to effect scene transition or jump).
Three-dimensional digital models are polygonal representations of objects, typically displayed with a computer or other video device. The displayed object may be a real world entity or an imaginary object. The three-dimensional digital model body of the meta universe consists of three-dimensional digital models, rendering, special effects, animation and other elements.
The three-dimensional digital model signature and signature checking machine can sign or check the three-dimensional digital model under a plurality of virtual scenes. The same three-dimensional digital model may be signed by any of a number of organizations.
Virtual space scene: an interactive or browsable three-dimensional digital space constructed by a three-dimensional digital model can be used as a whole metauniverse by a virtual space scene constructed by an independent three-dimensional digital model. Or constructing the whole metauniverse by a plurality of virtual space scenes, wherein each virtual space scene belongs to different individuals.
The signature verification mainly adopts a CA certificate signature verification mode.
In the meta-universe, a three-dimensional digital model is not provided with an appropriate ownership mechanism, unlike a real-world three-dimensional real object and a two-dimensional image. When a virtual scene is accessed, the ownership of the three-dimensional digital model constituting the scene is not known, so that the ownership of the three-dimensional digital model cannot enjoy the value possessed by the three-dimensional digital model production or design. ( For example: a is made into a three-dimensional statue model through software, the model is purchased by B and placed in the meta universe established by B, and C imitates the three-dimensional statue model graph of A to also make the three-dimensional statue model with the same appearance and place the model in the meta universe. The three-dimensional statue model imitated by C is sold by D. C infringes the copyright of a. However, other users accessing D cannot well determine who the ownership of the three-dimensional figurine model is, resulting in random use of the simulated three-dimensional figurine, and diffusion copying is easier because the three-dimensional digital model is electronic data. )
NFT, collectively referred to as Non-fungbletoken, refers to a Non-homogeneous communication certificate, essentially a trusted digital rights certificate with unique characteristics in a blockchain network, and is a data object capable of recording and processing multidimensional and complex attributes on a blockchain. The method is a means for solving the problem of digital artwork (all three-dimensional digital models can be regarded as digital artwork, pictures in a three-dimensional space can also be regarded as a three-dimensional digital model, and three dimensions of the pictures have values of 1 or 0, so that the three-dimensional digital model of the pictures is watched as a picture), but a metauniverse can be composed of a plurality of virtual space scenes, and in the current metauniverse technology, NFT can be used in one metauniverse scene built under the same technical system. Or a cross-chain technology is used for ensuring the unification of the value of the digital artwork under two technical systems. The NFT technology is complex to build, has extremely high cost and is not suitable for popularization. The use of the personal universe scene builder cannot be satisfied.

(1) A establishing ownership for three-dimensional digital model
As shown in fig. 2, a creates a three-dimensional digital model and generates a digital abstract of the three-dimensional digital model through calculation. The three-modulus word model digital digest information may be digital digest information of the three-dimensional model, code information, or the three-dimensional model itself.
Firstly, a three-dimensional digital model producer A can encrypt a digital abstract of three-dimensional digital model data and identity information of the producer A by using a private key of the producer A to obtain signature information.
(2) B, checking labels of the three-dimensional digital model manufactured by the A
As shown in fig. 3, B obtains a public key of a, where the public key may be sent from a to B, or a may be placed on a public network, and B queries through the public network to obtain the public key of a and identity information of a.
And B, decrypting the signature information by using the public key of A to obtain a digital abstract of the three-dimensional digital model and the identity information of A.
And B, obtaining the digital abstract information of the three-dimensional digital model through calculation.
Comparing the identity information of a may determine that the signature is signed by a. And comparing the digital abstract information of the three-dimensional digital model, wherein the digital abstract in the signature has a corresponding relation with the three-dimensional model if the digital abstract information is the same, namely the digital abstract is obtained by calculation of the three-dimensional model. From this, it can be derived that the ownership of the three-dimensional model is A.
(3) A authorizes B
As shown in FIG. 4, B provides A with its identity information, or A obtains B identity information by other means (network public channel query obtains, solicits B)
A encrypts digital abstract information of a three-dimensional digital model, A identity information and B identity information by using own private key to obtain authorization information
(3) C verifying whether B obtains authorization of A
As shown in FIG. 5, C obtains the public key information of A and the identity information of A and B (solicitation or query from public channels)
C, calculating the three-dimensional digital model to obtain a digital abstract of the three-dimensional digital model;
c, decrypting the signature information of the three-dimensional digital model by using the public key of the A to obtain digital abstract information of the three-dimensional model, identity information of the A and identity information of the B;
the model is authorized by A by comparing with the identity information of A, and B is authorized by comparing with the identity information of B. Comparing the digital abstract information of the three-dimensional digital model, the three-dimensional model is manufactured by A.
Thus, when C accesses B's metauniverse or the metauniverse owned by a metauniverse B, it is known by verification that the model in B's metauniverse has been authorized by A.
The prior art stores and blockchains digital asset information with personal information to prove ownership of the model. (NFT technology) but cannot circumvent the digital asset being used. A person purchases a digital avatar in 1050 thousands of dollars, the avatar ownership being recorded in the blockchain, the person owns the avatar ownership, but it cannot prevent others from using the picture on the internet platform. In a metaspace virtual space. The value of the model is higher, and the building cost of the blockchain is too high, so that the ownership of the model can be known only by verifying the ownership of the model through a signature tag verification machine in a cross-platform mode. The signature verification machine only comprises a public key and a private key of a user, and the cost is low. Meanwhile, the signature verification mode can be used for authenticating ownership under different network environments and different technical frameworks.
