Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metaverse security, and particularly relates to an information protection method based on multiple digital human images. BACKGROUND

[0002] A digital human, also called a virtual digital human, refers to a "person" existing in a digital world, and is a product of the integration of technology and culture. The digital human can be created through various digital technologies to have a virtual appearance. The virtual digital human can replicate human knowledge, memory and thinking to a certain extent, and can be endowed with intelligent, emotional and thoughtful characteristics in humanized design.

[0003] At present, digital humans are applied to various application scenarios in various industries, and can perform computing or control tasks using established programs. This includes, but is not limited to, guiding in the transportation industry, acting in the entertainment industry, course guidance in the teaching industry, interpretation in scenic spots, museums and exhibition halls, live streaming, promotion and sales in the sales industry, and online customer service or telephone customer service in the customer service field.

[0004] With the development of the metaverse, digital humans have been further applied in the metaverse network, especially for multi-user communication and exchange in the metaverse, bringing a more profound experience. Users can use the shell of a digital human to communicate and exchange with other users or digital humans in the metaverse, thereby being more immersed in the metaverse network to obtain a virtual and real network experience.

[0005] However, in this process, considering that users in the metaverse network will also face a variety of needs, such as learning, medical treatment, meetings, shopping, entertainment and the like, the corresponding metaverse scenes often have some same but not completely same situations. For example, there are learning methods that combine learning with entertainment, and academic exchanges are completed in the form of entertainment. Such metaverse scenes have both learning elements and entertainment elements, but the proportion of learning elements and entertainment elements is different.

[0006] When users communicate and exchange in different metaverse scenes through digital human images, there is a need to hide part of the personal information. For example, in the scene of a metaverse hospital, the digital human of a user cannot disclose the relevant information of the project executed in a metaverse research institute or the illness information of a patient diagnosed by the user when communicating and exchanging with other digital humans.

[0007] In addition, when the user communicates and exchanges in different metaverse scenes through the digital avatar, the user needs to consider the metaverse scene in which the digital avatar is located, and then the communication in the metaverse scene needs to meet the scene requirements. For example, when the future development direction of the company is discussed in the metaverse conference scene, the digital person owned by the user is negotiating with other digital persons about playing games after the meeting, and similar situations are inappropriate in the metaverse conference scene.

[0008] Meanwhile, in the metaverse scene, the digital person owned by the user needs to consider whether the metaverse scene has requirements for the dress style of the digital avatar when communicating and exchanging with other digital persons. For example, in the metaverse hospital scene, the digital avatar with the identity of a doctor will wear a white coat, instead of a digital avatar wearing a swimsuit being displayed in front of a digital avatar with the identity of a patient. Therefore, corresponding to different metaverse scenes, the digital avatar needs to correspond to the identity and take different costumes.

[0009] Based on the above situation, the present application provides a multi-digital avatar-based information protection method, device and system, which configures operation permissions corresponding to digital avatars in different identities and metaverse scenes, thereby protecting the information security of users owning digital avatars, which is a technical problem that needs to be solved at present.

[0045] Techniques, methods, and devices known to those of ordinary skill in the relevant art can not be discussed in detail, but should be considered part of the patent specification where appropriate. In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments can have different values. Embodiment

[0046] In this embodiment, the user has multiple identities in the metaverse, such as a teacher, a student, a doctor, a patient, etc. When the user presents himself through his digital avatar, the corresponding identity needs to be selected to match the metaverse scene he is in.

[0047] Referring to Figure 1 As shown in a flowchart provided by the present application. The implementation steps S100 of the method are as follows:

[0048] S101, acquire the scene information of the metaverse scene where the digital avatar is located, and the identity information of the digital avatar in the metaverse scene; the digital avatar is configured with corresponding operation permissions in different identities and / or metaverse scenes.

[0049] In this embodiment, the digital avatar is a presentation of the digital person in the metaverse scene. After the user owns the digital avatar, he can express the information he wants to express through the digital person, and communicate and exchange with other users and other digital persons in the metaverse through the aforementioned digital avatar, so as to achieve the effect of experiencing immersive communication and exchange in the metaverse scene.

[0050] The metaverse scene in this embodiment can be divided into metaverse scenes of different types, including but not limited to metaverse hospitals, metaverse schools, metaverse guidance agencies, metaverse airports, metaverse entertainment, metaverse shopping, and metaverse shopping malls.

[0051] It should be noted that the metaverse scene can set metaverse sub-scenes according to different types. Among them, the arrangement mode of multiple metaverse sub-scenes can adopt a parallel metaverse sub-scene arrangement mode, or a progressive metaverse sub-scene arrangement mode.

[0052] As an example but not limitation, taking the metaverse school as an example, the progressive metaverse sub-scene arrangement mode can be that the metaverse school is divided into university, high school, junior high school, primary school and kindergarten according to the type of the school, that is, the types of metaverse sub-scenes in the metaverse school scene include but are not limited to metaverse university, metaverse high school, metaverse junior high school, metaverse primary school and metaverse kindergarten. The promotion path of the school from low to high order is metaverse kindergarten, metaverse primary school, metaverse junior high school, metaverse high school and metaverse university. Among them, taking the metaverse university as an example to further subdivide the metaverse sub-scene, the metaverse university can be marked as 985 colleges and universities, 211 colleges and universities, double first-class colleges and universities, etc.

[0053] The parallel meta-universe sub-scene arrangement mode can be used for a large number of university campus scenes in the meta-universe, and different scene types can be divided according to teaching buildings, canteens, dormitories, playgrounds, auditoriums, libraries and the like. In addition, the users and / or digital humans in the university can also divide the teaching scenes and dormitory scenes in the meta-universe university according to different selected majors, so as to realize the arrangement of a plurality of meta-universe sub-scenes in the meta-universe school scene according to different types.

[0054] It should be further pointed out that the parallel meta-universe sub-scene arrangement mode and the progressive meta-universe sub-scene arrangement mode can also be used in combination to adapt to the arrangement of the meta-universe scene.

[0055] In the embodiment, the identity information can be an identity, a role or a duty possessed by a user or a digital human in the meta-universe, including but not limited to a doctor, a teacher, a salesperson, a lawyer, a firefighter, a nurse, a student, a bank clerk and the like.

[0056] It is considered that a user can exhibit multiple identities possessed by himself in the meta-universe network, and the foregoing identities can be exhibited by a digital human image possessed by the user, so as to distinguish the digital human images according to the differences of the digital human images under different identities.

[0057] By way of example but not limitation, user 1 in the meta-universe network has four digital human images, namely digital human image 1, digital human image 2, digital human image 3 and digital human image 4. Among them, digital human image 1 is set corresponding to the doctor identity of the user, and the corresponding operation permission can view the illness information and the inquiry record information of the patient; digital human image 2 is set corresponding to the sales identity of the user, and the corresponding operation permission can view the sold-out information of the goods and the purchase record information of other users or digital humans; digital human image 3 is a researcher in the meta-university research institute scene, and the operation permission can view the relevant process information of the corresponding project; digital human image 4 is a student identity in the meta-university school scene, and the operation permission is to watch the corresponding course video and has the operation permission of uploading homework after class.

[0058] For another example, user 2 in the meta-universe network has two digital human images, namely digital human image 5 and digital human image 6. Among them, digital human image 5 is a lawyer identity in the meta-university law firm scene, and the corresponding operation permission is to view the relevant materials of the relevant clients served by user 2 in the meta-university law firm scene; digital human image 6 is a volunteer in the welfare agency in the meta-university old-age care scene, and the corresponding operation permission is to provide corresponding services for the old people seeking help in the meta-universe network.

[0059] The plurality of digital human images can be configured according to different combinations of clothes, makeup, and styles, so that the digital human images of a user under different identities are different, and the digital human images of different users are different, thereby distinguishing the digital human images of different users under different identities.

[0060] In S102, the digital human image is switched and / or identified according to the aforementioned identity information in different meta-universe scenes, so as to display a specific digital human image in a specific scene, thereby protecting the information security of the user who owns the digital human image.

[0061] Since the digital human image is configured with corresponding operation permissions in different identities and / or meta-universe scenes, when the meta-universe scene of the digital human image changes, the meta-universe scenes before and after the change are preferably compared, and the operation permissions of the digital human image before and after the change of the meta-universe scene are determined according to the identity information of the digital human image in the meta-universe scene before the change and the identity information of the digital human image in the meta-universe scene after the change, thereby protecting the information security of the digital human image and the information security of the user who owns the digital human image.

[0062] It should be emphasized that displaying a specific digital human image in a specific scene not only protects the information security of the user who owns the digital human image, but also protects the information security of the digital human image.

[0063] As an example but not limitation, when the user is offline in the meta-universe scene and the digital human image owned by the user is displayed as online, the digital human image will communicate with other digital human images or other users in each scene of the meta-universe according to the predetermined procedure and perform corresponding operations.

[0064] However, even in the case where the user is offline and the digital human image owned by the user is displayed as online, real-time monitoring is needed to protect the information security of the digital human image and the information security of the user who owns the digital human image, so as to analyze whether the digital human image has performed an operation beyond the operation permission according to the operation performed by the digital human image, so as to avoid network vulnerabilities caused by the operation performed by the digital human image beyond the operation permission set for the corresponding meta-universe scene and identity, and further avoid the information of the digital human image and the user who owns the digital human image from being exploited or attacked by network hackers.

[0065] It should be further noted that the operation permission can also match the identity level of the aforementioned digital human image under different identities.

[0066] Considering that the identity level displayed by the digital human image under different identities is different, the identity level displayed by the digital human image under different identities in different meta-universe scenes is different, thereby resulting in different corresponding operation permissions.

[0067] By way of example but not limitation, when the identity levels are set as the first identity level, the second identity level and the third identity level, the operation permissions corresponding to the first identity level correspond to the largest range, the operation permissions corresponding to the second identity level correspond to the second largest range, and the operation permissions corresponding to the third identity level correspond to the smallest range. There are digital human image 1, digital human image 2 and digital human image 3 corresponding to different metaverse scenes, and each digital human image in each metaverse scene has a corresponding identity level, so that each digital human image in each metaverse scene has different operation permissions according to the identity level corresponding to the identity.

[0068] Preferably, the types of the metaverse scenes include metaverse hospital, metaverse school, metaverse tutoring agency, metaverse airport, metaverse entertainment, metaverse shopping and metaverse mall; the metaverse scene can set metaverse sub-scenes according to different types.

[0069] Preferably, the scene information includes type information of the metaverse scene, and entry time information and exit time information of the digital human image.

[0070] Preferably, the operation permissions match the identity levels corresponding to the digital human image in different identities; the operation permissions include operation permissions of the digital human image and operation permissions of the user holding the digital human image.

[0071] It should be emphasized that the operation permissions include operation permissions of the digital human image and operation permissions of the user holding the digital human image.

[0072] Therefore, in order to protect the information security of the digital human image and the information security of the user holding the digital human image, the operation permissions of the digital human image and the operation permissions of the user holding the digital human image in different identities and different metaverse scenes are set.

[0073] Preferably, when the digital human image in different metaverse scenes is switched and / or identified, at least one of the following situations should be met: situation one, one user has multiple digital human images; situation two, multiple users use the same digital human image; situation three, one user authorizes the digital human image owned by the user to other users.

[0074] It should be noted that, in the metaverse network, there are various scenarios in which a user has a digital human avatar, i.e., scenario one, a user has multiple digital human avatars; scenario two, multiple users have the right to use the same digital human avatar, which represents that a digital human avatar can be provided for use by multiple users; and scenario three, a user authorizes the digital human avatar owned by the user to be used by other users.

[0075] Preferably, when the switching and / or identification includes one of the aforementioned scenarios, the digital human avatar in one of the aforementioned scenarios is replaced; and the replaced digital human avatar can perform relevant operations according to the operation permissions obtained thereby.

[0076] When the switching and / or identification includes one of the aforementioned scenarios, the digital human avatar owned by the user is replaced, at this time, the operation permissions of the digital human avatar in different metaverse scenarios and under different identities are pre-set. When the metaverse scenario is switched, the digital human avatar is also replaced, which makes the setting of the operation permissions of the digital human avatar and the setting of the operation permissions of the user holding the digital human avatar consistent with the identity of the user in the metaverse scenario, so it is not necessary to adjust the operation permissions of the digital human avatar.

[0077] Preferably, when the switching and / or identification includes scenario two and / or scenario three, a digital watermark is added to the digital human avatar in scenario two and / or scenario three to mark the digital human avatar owned by the user at the current time; and the replaced digital human avatar can perform relevant operations according to the operation permissions obtained thereby.

[0078] When the switching and / or identification includes scenario two and / or scenario three, a digital watermark is added to the digital human avatar owned by the user, so as to mark the identity information of the user using the digital human avatar at the current time on the digital human avatar.

[0079] The digital watermark has the following characteristics: transparency, the watermark is closely combined with the original data and hidden therein, and the existence of the watermark cannot destroy the appreciation value and use value of the original data; robustness, the ability to detect the watermark after normal processing operations such as lossy compression, recording, printing, scanning, rotation, translation, etc.; security, the ability to resist unauthorized deletion, embedding and detection attacks by attackers; identification, the watermark should have an identifier to mark the current copy of the digital work.

[0080] In the embodiment, the digital watermark displays the identity information of the user using the digital human avatar on the digital human avatar on the interactive interface through a digital watermark technology. The digital watermark preferably uses a spatial domain watermark to load the digital watermark onto the digital human avatar.

[0081] The advantage of using the digital watermark is that other digital human images and / or other users on the interactive interface can only learn the identity information of the digital human image and the current identity information of the user holding the digital human image in the metaverse scene, so as to realize interactive operation with the digital human image with the identity information and / or the user owning the digital human image under the identity information. This ensures that other digital human images and / or other users on the interactive interface cannot master the operations and related information performed by the user in all metaverse scenes from other scenes outside the metaverse scene, thereby avoiding the leakage of user information.

[0082] Another reason for using the digital watermark is that when there are multiple digital human images that are similar or identical in appearance in the metaverse scene, the digital watermark loaded on the digital human image can be used to distinguish them.

[0083] Optionally, the user holding the digital human image can add different accessories to the digital human image to distinguish between digital human images that are similar or identical in appearance.

[0084] For the switching and / or identification including the second and / or third cases, it should be noted that the digital human images in the second and third cases are not pre-set for the user, but are authorized for use after the user applies for them. Therefore, the user cannot pre-set the corresponding operation permissions for the digital human image before being authorized, and needs to assign operation permissions to the digital human image after being authorized. The setting of the operation permissions has a time limit, which is determined by the length of time the user controls the digital human image.

[0085] It should be emphasized that the above three cases rarely exist independently, and in most cases, they exist in the metaverse scene in the form of combination of the above three cases.
