Description

Technical Field

[0001] This application relates to the field of data security technology, and in particular to an authorization and authentication method, system and storage medium for a three-dimensional model system for data security. Background Technology

[0002] In today's digital age, data security has become a critical issue. 3D modeling systems are widely used in numerous fields, such as industrial design, architectural planning, virtual reality, and urban metaverse. These 3D models contain a wealth of valuable information, including intellectual property, trade secrets, and sensitive data. Therefore, ensuring the security of 3D model data is of paramount importance.

[0003] Currently, many 3D modeling systems fail to adequately implement data security and protection measures during delivery. In some cases, users can log in and use the system without authentication after installation, posing a serious risk of data leakage. Common authorization, encryption, and authentication methods for 3D modeling systems fall into two main categories: account and password authentication, where users simply enter their correct username and password to log in; and authorization serial numbers or authorization files, which grant access after authorization. However, these authentication methods are relatively simplistic, relying solely on username and password authentication is far from sufficient. More reliable multi-factor authentication is needed, and these systems are vulnerable to attacks such as role impersonation, password theft, and tampering, failing to meet complex security requirements. Existing technologies in this area still have many shortcomings. Summary of the Invention

It should be understood that the following drawings only show some embodiments of this application and should not be regarded as a limitation of the scope.

[0026] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this application.

[0028] In the description of the embodiments of this application, technical terms such as "first" and "second" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly defined.

[0029] like Figure 1 As shown, in one embodiment, the authorization and authentication method mainly includes steps S100-S700, which mainly involve at least three authentication methods such as user account password authentication, user terminal identity authentication, and 3D model resource authentication.

[0030] S100, Obtain the authorization and authentication request initiated by the user terminal of the 3D model system. The authorization and authentication request includes a user identity acquisition request, an identity authentication request, and a 3D model resource loading request.

[0031] S200, responding to the user identity collection request, obtain the first identity information of the user terminal.

[0032] S300, in response to the 3D model resource loading request, obtain the second identity information of one or more 3D model resources preloaded into the 3D model system.

[0033] S400, in response to the identity authentication request, obtain the third identity information stored in the verification module that corresponds to the first identity information.

[0034] S500, verify the user's identity and access permissions based on the first identity information and the third identity information;

[0035] S600, verify the user's access rights to the 3D model resources based on the first identity information, the second identity information and the third identity information.

[0036] S700, if both the access permission verification and the usage permission verification pass, feedback is given allowing the user's 3D model system to load one or more of the requested 3D model resources.

[0037] In some embodiments, the first identity information includes at least one or more of user account password information, user terminal hardware information, and collection timestamp, and at least includes user account password information. The user terminal hardware information is used to verify the binding status between the user terminal and the user account. The collection timestamp is used to verify the real-time nature of user identity collection.

[0038] For example, in step S200, responding to the user identity collection request and obtaining the user's first identity information can be done simply through the user's account and password information for initial authorization authentication. In some embodiments, authorization authentication can also be performed using the user's account and password information and the user's hardware information. This not only verifies the correctness of the user's entered account and password but also verifies the physical hardware device of the user's terminal to ensure that the user can only log in and use the device on the bound authorized hardware device. The user's hardware information can include hardware serial number, hardware model, network card MAC address, and BIOS information, such as the motherboard, CPU, hard drive, and graphics card of the user's terminal. The BIOS information includes the BIOS version number and manufacturer information. In some embodiments, authorization authentication can also be performed using the user's account and password information, user's hardware information, and a collection timestamp. When obtaining the user's entered account and password information and user's hardware information, a timestamp is generated simultaneously for real-time collection and to prevent tampering.

[0039] In some embodiments, steps S100-S700 can all be performed on the local user terminal. In other embodiments, steps S100-S700 can be an online authentication process, jointly completed by the user terminal and the cloud server.

[0040] For example, step S100 may involve the cloud server obtaining an authorization and authentication request initiated by the user terminal of the 3D model system, parsing the request, and breaking it down into a user identity acquisition request, an identity authentication request, and a 3D model resource loading request, and executing steps S200-S400 respectively.

[0041] When executing S200, the required primary identity information can be extracted directly from the user identity collection request, such as user account password information, user terminal hardware information, and collection timestamp. In some embodiments, after the initial authorization authentication of the user account password is completed, the cloud server instructs the user terminal to collect user terminal hardware information. If the user account password verification fails, the authorization authentication is terminated directly, and a verification failure notification is sent.

[0042] In step S300, when the 3D model resource is already stored on the user terminal, the cloud server instructs the user terminal to obtain the second identity information. When the 3D model resource is stored on the cloud server, the cloud server obtains the second identity information of the requested 3D model resource from the resource library based on the user account and / or user terminal hardware information.

[0043] In step S400, the verification module is stored on a cloud server. Alternatively, the initial user verification module can be stored on the local user terminal, and the secondary verification module can be stored on the cloud server. In step S500, the cloud server verifies the user's access rights based on the first identity information and the third identity information. In step S600, the cloud server verifies the user's access rights to the 3D model resources based on the first identity information, the second identity information, and the third identity information. In step S700, if both the access rights verification and the usage rights verification pass, the cloud server provides permission for the user's 3D model system to load one or more requested 3D model resources.

[0044] In some embodiments, after the cloud server responds to the 3D model resource loading request during the online authentication process, it can further determine whether the user terminal has stored one or more of the requested 3D model resources. If not, after completing the access permission verification and the usage permission verification, the pre-loaded 3D model resources are sent to the user terminal or online access permissions are provided.

[0045] In one embodiment, the second identity information may include at least one of global identity information, specific region identity information, model accuracy limitation information, and roaming interaction permission information, and can be configured in any way according to specific usage requirements.

[0046] The global identity information is mainly used to represent the global identity of the 3D model resource, including global identification information and / or global 3D feature information; wherein, the global identification information includes identification information pre-configured for the 3D model resource, used to verify the user account's access rights to the 3D model resource through the identification information; the global 3D feature information includes feature information automatically calculated and generated by performing 3D model feature recognition on the 3D model resource, used to verify the user account's access rights to the 3D model resource through the feature information.

[0047] The specific region identity information is mainly used to represent the specific region identity existing in the 3D model resource, including specific region identification information and / or specific region 3D feature information; wherein, the specific region includes a target region associated with the user account; the specific region identification information includes identification information pre-configured for the specific region existing in the 3D model resource, used to verify the user account's access rights to the 3D model resource through the identification information; the specific region 3D feature information includes feature information automatically calculated and generated by performing 3D model feature recognition on the specific region existing in the 3D model resource, used to verify the user account's access rights to the 3D model resource through the feature information.

[0048] In this context, "global" refers to the entire space of the 3D scene displayed after the 3D model resources are loaded into the 3D model system, while "specific region" refers to a designated area or a portion of the space within the entire 3D scene that meets relevant rules. Both global 3D feature information and global identifier information, as well as specific region 3D feature information and specific region identifier information, involve feature information and identifier information. The difference between 3D feature information and identifier information is that identifier information is one or more labels configured according to preset configuration rules, while 3D feature information is 3D model feature point information automatically generated according to a preset feature recognition algorithm. In some embodiments, the identifier information can be a 3D scene name, such as a model name, game name, city name, place name, park name, character name, user-associated name, etc.

[0049] In some embodiments, the feature information may include scene 3D features of the 3D model, such as the regional features, distribution features, and / or distinctive features of any 3D model in the scene, such as building models, vegetation models, mountain models, river models, and lake models. In some embodiments, the feature information may also include 3D anti-counterfeiting information; the 3D anti-counterfeiting information includes hidden watermarks and / or visible watermarks. The 3D feature information of a specific area includes feature information automatically calculated by performing feature recognition on a specific area existing in the 3D model resource that includes scene 3D features and / or 3D anti-counterfeiting information; the 3D feature information of the entire domain includes feature information automatically calculated by performing feature recognition on the 3D model resource that includes scene 3D features and / or 3D anti-counterfeiting information.

[0050] In some embodiments, the model precision limitation information is used to verify the user's permission to use the precision of the 3D model resources loaded in the 3D model system. The model precision limitation information can be the highest precision in the entire scene, the precision level required by the user, the precision level of a specified area, etc., and can be divided into various precision levels, such as L1-L5 levels, or meter-level, sub-centimeter-level, centimeter-level, millimeter-level, etc.

[0051] The roaming interaction permission information is used to verify the user's roaming interaction permissions in the 3D scene formed by loading the 3D model resources. The roaming interaction permission information may include restrictions such as the roaming range in the scene space, whether the user can view the 3D model up close, and whether the user can view the internal structure.

[0052] During authorization and authentication, if any of the following does not match: the first identity information of the user initiating the authorization request, the second identity information of the 3D model resource to be loaded, and the third identity information stored in the verification module, namely, the global identity information, the specific region identity information, the model precision limitation information, and the roaming interaction permission information, then the authorization fails and the user client is not allowed to load and access the corresponding 3D model resource. In some embodiments, the user client may also be prevented from loading and running the 3D model system.

[0057] This application also discloses an online authorization system for a 3D model system. The online authorization system mainly consists of a cloud server and a user terminal, and is configured to perform authorization authentication based on the online authentication method. The cloud server mainly includes a first processing module, a second processing module, a third processing module, a communication module, an access permission verification module, a usage permission verification module, and a fourth processing module.

[0058] This application also discloses a computer-readable storage medium for storing a computer program. When a computer reads the computer program from the storage medium, the computer runs the authorization and authentication method described in the first aspect or the online authentication method described in the second aspect.
