Detailed Description

All other embodiments that can be derived from the disclosure by one of ordinary skill in the art based on the embodiments in the disclosure are intended to be within the scope of the disclosure.

In the related art, the internet platform can record the virtual identity information of the user, so that the risk of leakage of the virtual identity information exists, and the privacy protection of the user is not facilitated.

In order to solve the above problem, an embodiment of the present disclosure provides a terminal device, and referring to fig. 1, fig. 1 is an architecture diagram of a terminal device provided in an embodiment of the present disclosure, the terminal device includes a SIM (Subscriber Identity Module) card 101 and a metastic application Module 102, where:

Wherein, the virtual identity information is: when a first user who logs in the metas application module 102 registers an SIM card, the SIM card 101 is generated based on a private key of the first user; the private key of the first user is obtained by performing hash calculation on a preset random number.

The metas application module 102 is further configured to send an authentication request to the metas platform based on the virtual identity information, so that the metas platform authenticates the authentication request based on the virtual identity information.

The terminal equipment provided by the embodiment of the disclosure can generate the virtual identity information of the user when the user registers the SIM card, store the virtual identity information in the SIM card, and subsequently, based on the virtual identity information recorded in the SIM card, the user can access the metas platform without recording the virtual identity information of the user on each Internet platform, so that the risk of virtual identity information leakage is reduced, and the privacy protection of the user is facilitated.

The terminal device provided by the embodiment of the disclosure can be applied to different scenes, for example, the terminal device can be a mobile phone, and a user can communicate with the metas platform through the mobile phone. Accordingly, the SIM card in the terminal device represents a SIM card built in the mobile phone, and the metastic application module may include an application installed in the mobile phone for accessing a metastic platform.

An embodiment of the present disclosure further provides a SIM card, as shown in fig. 2, fig. 2 is a structural diagram of a SIM card provided in an embodiment of the present application, including: a computing chip 201, a SIM card module 202 and a communication module 203;

and the computing chip 201 is used for carrying out data communication with a metastic application module in the terminal equipment through the communication module 203.

The SIM card in the present disclosure may also be referred to as a BSIM (block chain Subscriber Identity Module) card. The metastables platform application module may be metastables software installed for the terminal device.

In one implementation, as shown in fig. 3, fig. 3 is a schematic diagram of a hardware structure of a BSIM card according to an embodiment of the present disclosure. In fig. 3, the BSIM card includes a SIM card module 301, a bluetooth module 302, a computing chip 303, and an interface module 304. The SIM card module 301 includes the hardware structure of a conventional SIM card, the bluetooth module 302 is the communication module in the above embodiment, and the interface module 304 includes a specific interface described later. The computing chip 303 is configured to generate virtual identity information of a user, sign a transaction record, generate a unique identifier of a virtual asset, and verify the identity of the user, and specifically, will be received in detail in the following embodiments. The computing chip 303 has a financial security level.

In one implementation, the BSIM card may support block chain algorithms such as ECC-secp256k1 (Elliptic Curve Algorithm, elliptic Curve Cryptography), AES (Advanced Encryption Standard), ECDSA-secp256k1 (Elliptic Curve Digital Signature Algorithm ), HMAC-SHA512 (Hash-based Message Authentication Code), and the like. The BSIM card supports a blockchain digital currency protocol such as BIP32 (a wallet layering scheme), BIP44 (a wallet mnemonic creation scheme) and the like. The storage space in the BSIM card is more than 1M, and the user space is more than 450K; the signature speed is less than 150ms. The user space is used for storing virtual identity information, virtual assets, a mobile phone number, an encryption seed and a private key of a user.

In one implementation, the BSIM may be implemented by the following architecture: the system comprises a JAVA application layer, a JAVA platform, a hardware interface layer and a hardware layer. The JAVA application layer is used for realizing block chain application logic in the BSIM card, and comprises seed generation, public and private key generation, encryption storage, digital signature generation, private key recovery, backup and the like. The JAVA platform layer can realize JAVACARD virtual machine and card content management functions and provide a JAVA interface called by an application.

The hardware layer can improve the performance of the algorithm through the hardware algorithm IP coprocessor. The hardware algorithm IP coprocessor is the computing chip in the above embodiments.

Based on the same inventive concept, the embodiment of the present disclosure further provides a communication method, which may be applied to an SIM card and a metastic application module in a terminal device. The SIM card and the metastic application module may be the SIM card 101 and the metastic application module 102, respectively, in the terminal device in fig. 1. Referring to fig. 4, fig. 4 is an interaction diagram of a communication method provided by an embodiment of the present disclosure, where the method may include the following steps:

s401: when the metastic platform needs to be accessed, the metastic application module sends an identity information request to the SIM card.

S402: and when the SIM card receives the identity information request, the SIM card acquires the locally recorded virtual identity information and sends the virtual identity information to the metacavic application module.

Wherein, the virtual identity information is: when a first user logging in the metachrosis application module registers an SIM card, the SIM card is generated and obtained based on a private key of the first user; the private key of the first user is obtained by performing hash calculation on a preset random number.

S403: and the metas application module sends an authentication request to the metas platform based on the virtual identity information so that the metas platform authenticates the authentication request based on the virtual identity information.

According to the communication method provided by the embodiment of the disclosure, the virtual identity information of the user can be generated and stored in the SIM card when the user registers the SIM card, and subsequently, based on the virtual identity information recorded in the SIM card, the user can access the meta platform without recording the virtual identity information of the user on each Internet platform, so that the risk of virtual identity information leakage is reduced, and the privacy protection of the user is facilitated.

In addition, in the related art, the virtual assets and virtual identities are the core of the meta universe and bear the asset interests and social identities of the users in the meta universe. However, since the virtual identity interpretation right of the user is in the Internet platform mechanism, the ownership attribute is not clear, and the development of the meta universe is hindered.

Based on the method of the embodiment of the present disclosure, the virtual identity information of the user is recorded in the SIM card registered by the user, so that the user can have ownership of the virtual identity information, that is, ownership of the virtual identity information can be made clear, and the development of the meta universe is promoted.

For step S401, the metastables platform corresponds to a metastables application module, i.e., a user may access different metastables platforms through different metastables application modules.

In one implementation, when a user starts a metastic application module in a smart terminal, the metastic application module may send an identity information request to a SIM card. For example, the metas application module may call an SDK (Software Development Kit) through a specific interface, and then, send an identity information request to the SIM card through the SDK to obtain the identity information stored in the SIM card. The specific interface can be an interface provided by an operating system of the intelligent terminal.

With respect to step S402, the first user is a user who needs to access the metastables through the metastables application module when using the smart terminal currently. In one implementation, the first user may apply for registering the SIM card with the operator, and the SIM card may generate virtual identity information of the first user when registering the SIM card.

For step S403, in one implementation, the virtual identity information of the first user may include a DID. That is, when a first user registers a SIM card, an operator may store the DID of the first user into a blockchain constructed by the operator. Accordingly, the metastables application module may generate a DID verifiable claim based on the DID of the first user and send an authentication request carrying the DID verifiable claim to the metastables platform. Correspondingly, the metastic platform can acquire the DID of the first user stored in the block chain constructed by the operator, and verify the DID verifiable statement based on the DID, and thus can authenticate the authentication request. Wherein the authentication request, i.e. the first user, is authenticated.

For example, the DID may contain a DID identifier and a DID document including: the public key of the first user, a set of encryption protocols, a set of service endpoints, a creation timestamp of the DID document, and a JSON-LD (JavaScript Object notification-Linked Data, a method for representing and transmitting interlinked Data based on JSON) signature. Wherein the JSON-LD signature is used for verifying the legality of the DID document. The public key of the first user corresponds to a private key of the first user mentioned later.

In one implementation, the metastic platform may verify the DID verifiable claim carried in the authentication request based on the DID specification of W3C (World Wide Web Consortium). For example, it may be determined whether the signature in the DID-verifiable claim is legitimate, or it may be determined whether the DID in the DID-verifiable claim is a DID trusted by the metastables platform, i.e., whether the DID identifier and DID document characterized by the DID-verifiable claim are stored in a carrier-built blockchain. That is, when the first user accesses the metastables through the metastables application module, the metastables platform may obtain a DID verifiable statement of the first user, and if the DID verifiable statement passes the verification, it may be determined that the first user is successfully authenticated; otherwise, it is determined that the authentication of the first user fails.

In one implementation, referring to fig. 5, fig. 5 is a schematic diagram for accessing a meta universe platform according to an embodiment of the present disclosure. Each meta space in fig. 5 represents a meta space platform, and after a natural person (i.e., a user) performs real name authentication by an operator, the meta space platform can be logged in, and a plurality of different meta space platforms can be switched to be accessed. The operator stores the DID key (namely DID) of the user in the BSIM card chip, the metaspace platform can acquire the DID of the user from the operator, and subsequently, when the user accesses the metaspace platform, the metaspace platform can analyze and verify the DID verifiable statement, so as to authenticate the user. The DID identification specification definition based on the W3C can realize interconnection, intercommunication and mutual recognition of DIDs with unified specifications among the meta-universe platforms, and users can realize seamless switching among a plurality of meta-universe platforms, namely, the users can access different meta-universe platforms based on one DID without registering different DIDs in different meta-universe platforms. The blockchain infrastructure is a network operating based on blockchain technology, and an operator can participate in the construction of the blockchain infrastructure, and simultaneously, the blockchain can also store the DID. Additionally, a transaction record for each DID in the metastables platform may also be stored in the blockchain. The BSIM card is used for storing the virtual identity information of the user, digital identities among a plurality of meta-universe platforms can be communicated, a uniform identity authentication protocol across the meta-universe platforms is realized, and an authoritative, standard and credible user identity system infrastructure is constructed for the cloud universe platform.

In one implementation, referring to fig. 6, fig. 6 is an interaction diagram of another communication method provided by the embodiment of the present disclosure, and on the basis of fig. 4, the method may include the following steps:

s404: the metastic application module acquires a transaction record of the first user in the metastic platform.

S405: the metastic application module sends a transaction record to the SIM card.

S406: and the SIM card encrypts the transaction record based on the private key of the first user to obtain a corresponding digital signature and sends the digital signature to the metas application module.

S407: the metastic application module obtains a digital signature from the SIM card and sends the transaction record and the digital signature to the metastic platform.

The metastables may use blockchains as infrastructure, e.g., the metastables may publish virtual assets based on blockchains.

When a user purchases or sells a piece of virtual asset in the metaspace platform, the metaspace platform may generate a transaction record to represent that the first user conducts a transaction of the virtual asset in the metaspace platform. For example, the transaction record may contain the time of the transaction, virtual identity information of the parties to the transaction, and the native identification of the virtual asset of the transaction. The original identifier of the virtual asset represents the identifier obtained when the virtual asset is generated.

In one implementation, the SIM card may process the transaction record based on a digital digest algorithm to obtain a string of fixed length, and then encrypt the string based on a private key of the first user to form a digital signature. The SIM card may send the digital signature to the metas application module through the blockchain interface. For example, the digital digest algorithm may be a Hash algorithm. The block link interface can be a hardware interface provided by the SIM card, and the SIM card can access the block link corresponding to each metastic platform through the hardware interface.

The metas application module may obtain a digital signature based on a block link interface in the SIM card and send the digital signature and its corresponding transaction record to the metas platform.

According to the communication method provided by the embodiment of the disclosure, when the user conducts virtual asset transaction, the transaction record is signed by using the private key of the first user stored in the SIM card, and the obtained digital signature and the transaction record are sent to the metas platform, so that the transaction record of the user can be prevented from being tampered, and the transaction cost is low and is not limited by time and space.

In an implementation manner, referring to fig. 7, fig. 7 is an interaction diagram of another communication method provided by an embodiment of the present disclosure, and on the basis of fig. 4, the method may include the following steps:

s408: and when detecting that the first user acquires the virtual assets in the metastic platform, the metastic application module sends the virtual assets to the SIM card.

S409: and the SIM card generates a unique identifier of the virtual asset based on the virtual identity information, and locally and correspondingly records the virtual asset and the unique identifier.

The first user can purchase virtual assets and exchange the virtual assets in the metastic platform through the metastic application module, and accordingly the metastic application module can send the virtual assets obtained by the first user to the SIM card.

In one implementation, the first user may use credits to purchase NFT (Non-homogeneous Token) digital merchandise such as digital artwork, game items, and the like. The integral can be a virtual asset obtained by recharging the first user on a service operation platform of an operator; or, the virtual assets given to the user by the operator according to the historical consumption records of the user can also be given.

In one implementation, the SIM card may splice the virtual identity information and the original identifier of the virtual asset, as the unique identifier of the virtual asset.

In the related art, virtual assets and virtual identities are the core of the meta-universe and bear the asset interests and social identities of users in the meta-universe. However, the data such as the virtual identity information and the derived related assets and activities lack privacy, which is not beneficial to protecting the privacy of the user. According to the communication method provided by the embodiment of the disclosure, unique identifiers can be generated for different assets in different metas based on the virtual identity information stored in the SIM card, so that the management of virtual assets by a user is facilitated, and further, the creation of metas trade ecology and the privacy protection of the user are facilitated.

In an implementation manner, as shown in fig. 8, fig. 8 is a flowchart of a generation process of virtual identity information provided in the embodiment of the present disclosure, where the process of generating virtual identity information by a SIM card includes:

s801: a random number is generated.

S802: and calculating the hash value of the random number based on a preset hash algorithm to obtain the private key of the first user.

S803: and generating the DID of the first user based on the private key of the first user as the virtual identity information of the first user.

In one implementation, upon registration of the SIM card by the first user, the SIM card may generate a Random Number of specified bytes through a hardware Random Number Generator (TRNG). And processing the random number based on a preset hash algorithm to obtain the private key of the first user.

And processing the private key of the first user based on a Hash algorithm to obtain a character string with a fixed length as a first Hash value. And acquiring bytes with a first numerical length of the first hash value, and taking the bytes with the first numerical length as a second hash value. And adding a DID role type byte before the second hash value, and taking the second hash value after the DID role type byte is added as a third hash value. And calculating the third hash value based on a hash algorithm to obtain a fourth hash value. And acquiring bytes with the second numerical value length of the fourth hash value, splicing the bytes with the second numerical value length with the third hash value, and taking the obtained spliced value as a fifth hash value. And coding the fifth hash value to obtain a DID corresponding to the first user as the virtual identity information of the first user.

The first byte may be the first 20 bytes, and the second byte may be the first 4 bytes. The Hash Algorithm may be SHA-512 (Secure Hash Algorithm-512, secure Hash Algorithm). The DID role type byte represents a role type represented by the DID, wherein the role type may be an application, a person or a device, etc. The encoding process of the fifth hash value may use a Base58 encoding method of bitcoin.

The designated byte can be 64 bytes, the length of the private key can be 512 bits, so that 512-power different private keys with 2 can exist, namely, the number of the private keys is close to 150-power of 10, the probability that the randomly selected private keys are the same is one-150-power of 10 and is close to 0, and further, the uniqueness and the safety of the private keys can be improved.

In one implementation, when the SIM card is lost or damaged, the user can recover the SIM card, and accordingly, the user identity can be verified. As shown in fig. 9, fig. 9 is a flowchart of a user authentication process provided in an embodiment of the present disclosure, where the process includes:

s901: when the user identity of the user to be verified needs to be verified, the user password and the user real identity information provided by the user to be verified are obtained.

S902: and determining the encrypted random number and the operator password corresponding to the user real identity information provided by the user to be verified based on the corresponding relationship among the pre-recorded user real identity information, the encrypted random number and the operator password.

Wherein, the encrypted random number recorded in the corresponding relation is: the password is obtained by encrypting based on a user password provided by the registered user and a corresponding operator password.

S903: judging whether the determined encrypted random number can be successfully decrypted or not based on the determined operator password and the user password provided by the user to be verified; if yes, go to step S904; if not, go to step S905.

S904: and determining that the user to be authenticated passes the identity authentication.

S905: and determining that the user to be authenticated does not pass the authentication.

In addition, the user may provide real identity information. The real identity information may include the user's name and identification number. The carrier password is generated by the carrier when the user registers the SIM card. The operator passwords corresponding to different users may be the same or different. For each user, when the user registers the SIM card, the SIM card can store the encrypted random number corresponding to the user, the operator password, and the real identity information provided by the user in the service operation platform of the operator after obtaining the corresponding encrypted random number.

The user to be verified is the user needing user identity verification at present, and when the user identity of the user to be verified needs verification, the SIM card can acquire the encrypted random number and the operator password which are recorded in the service operation platform and correspond to the real identity information provided by the user to be verified. Then, the SIM card decrypts the encrypted random number by combining a user password and an operator password provided by the user to be authenticated; if the decryption is successful, determining that the user to be verified passes the identity verification; and if the decryption is not successful, determining that the user to be authenticated does not pass the identity authentication.

The operator can write the recorded encryption seed and operator password corresponding to the real identity information such as the mobile phone number provided by the user to be authenticated into the SIM card. In addition, the SIM card can obtain the user password input by the user to be authenticated, and then the SIM card decrypts the encrypted seed based on the operator password and the user password, and if the decryption is successful, it is determined that the user to be authenticated passes the authentication, and correspondingly, the operator can recover the SIM card for the user to be authenticated, that is, the user to be authenticated obtains a new card, and retrieves the wallet (that is, the private key of the user to be authenticated); and if the decryption is not successful, determining that the user to be authenticated does not pass the identity authentication.
