Description

Technical Field

[0001] This invention relates to the field of virtual reality technology, and in particular to a method for achieving safe interaction of digital humans in a metaverse. Background Technology

[0002] The virtual world, also known as the virtual reality world, is a world independent of the real world but connected to it. Specifically, it refers to a network world based on a computer simulation environment, using virtual avatars as carriers, where users live and communicate. Users in the virtual world can choose virtual 3D models as their avatars and communicate with others through various media such as text, images, sound, and video.

[0003] In recent years, with the rise of the concept of the metaverse, related virtual reality technologies and products have emerged one after another. How to obtain a more realistic social experience in the metaverse network, and how to find friends with common interests and like-minded playmates are the most popular topics in virtual reality technology at present.

[0004] However, in this process, we also need to consider the real-world challenges of making friends. For example, with busy work schedules, people have fewer and fewer ways to make new friends. Meeting new friends or close friends often happens through recommendations from friends or through blind dates arranged by elders. This is especially true for introverted people, who often feel very tense and awkward when meeting strangers for the first time. Furthermore, after the first meeting, both parties familiarize themselves with each other's general situation, such as personality traits, characteristics, and preferences, before deciding whether to continue communication. In the real world, people consider the feelings of friends or elders; even if they don't want to continue the meeting, they will persist until it ends as a sign of respect.

[0005] In contrast, within the metaverse's network environment, people can freely make friends and connect with new people in their preferred way. Furthermore, they can directly and clearly refuse strangers they don't want to know, without having to consider the feelings of friends or elders, and without feeling embarrassed by a clear refusal.

[0006] In the metaverse, we can combine real-world friendship models with meeting, interacting, and communicating to learn about the other person's personality, characteristics, preferences, and other information. We also hope that after getting to know each other initially, we can proactively refuse without feeling awkward.

[0007] Furthermore, in the metaverse, interactions with people can be achieved through methods of making friends that are unlikely to occur in the real world. For example, in the metaverse, friends can be made through virtual scents, thus enabling interaction between digital people.

[0008] However, it is worth considering that when interacting in the metaverse, the information security of both parties needs to be protected. When one party requests to add another as a friend, the other party will have corresponding concerns. For example, the other party may think: Is this person reliable? Will my personal information be leaked by him? Before adding him as a friend, how can I assess the security risks this person poses to my personal information, so as to avoid adding such a digital person as my good friend in the metaverse?

[0009] Therefore, a method, device, and system for realizing secure interaction of digital humans in the metaverse are provided. This method enables virtual scent-based social interaction in the metaverse, thereby attracting digital humans to make friends in the metaverse while ensuring information security. This is a technical problem that urgently needs to be solved. Summary of the Invention

[0010] The purpose of this invention is to overcome the shortcomings of the prior art and provide a method, device and system for realizing the safe interaction of digital humans in the metaverse. This invention can attract digital humans to make friends in the metaverse through virtual scent social interaction while ensuring information security.

[0011] To address the existing technical problems, the present invention provides the following technical solution:

[0012] A method for ensuring secure interaction between digital humans in a metaverse, the method comprising the following steps:

[0013] The system sets up digital human images and virtual scent information for the digital humans within a metaverse, and generates virtual scent dispersion areas within a preset range of the digital humans; the digital humans include user digital humans and other digital humans.

[0014] Based on the interaction between the user's digital avatar and other digital avatars, information on changes in the virtual scent corresponding to the user's digital avatar and / or other digital avatars is displayed within the virtual scent dispersion area. This information can be displayed through an identifier, which is used to indicate whether the act of other digital avatars adding the user's digital avatar as a friend in the metaverse poses a risk to information security.

[0015] Furthermore, the virtual odor dispersion area includes virtual odor information corresponding to various parts of the digital human; the virtual odor dispersion area is defined by drawing a new outline outward from the outline of the aforementioned digital human image, and the area inside the new outline but outside the outline of the digital human image is set as the virtual odor dispersion area.

[0016] Furthermore, the determination of whether the act of other digital humans adding the user's digital human as a friend in the metaverse poses a risk to information security includes the following steps: comparing a first set of virtual scent information and a second set of virtual scent information; the first set of virtual scent information includes the virtual scent information and / or the change information of virtual scent when other digital humans add the user's digital human as a friend in the metaverse; the second set of virtual scent information includes the historical virtual scent information of other digital humans when adding other users' digital humans as friends in their historical interactions, and / or the historical change information of virtual scent; based on the results of the aforementioned comparison, determining the intention of other digital humans to add the user's digital human as a friend; and based on the correspondence between digital human behavior and information security risk status preset in the metaverse information security database, determining the information security risk corresponding to the digital human's request to add a friend.

[0017] Furthermore, the virtual odor information includes virtual location, virtual odor concentration, and virtual odor duration information; the virtual odor information can be adjusted by adding virtual perfumes; the virtual perfumes are pre-set according to the perfume types, characteristics, and quality standards in the real world, and are stored in the metaverse odor information database accordingly.

[0018] Furthermore, the interaction specifically includes communication between two or more digital humans in different scenarios within the metaverse, as well as teaming up to perform assigned tasks within the metaverse; the communication includes action interaction, text communication, voice calls, and video calls.

[0019] Furthermore, the aforementioned interaction process is monitored to detect changes in virtual odors at various locations within the virtual odor dispersion area and on the digital human image.

[0020] Furthermore, the location of the aforementioned change information is determined, and the change information is displayed in a way that differs from the surrounding information to reflect the information security risks of the digital human during the interaction process.

[0021] A device for ensuring safe interaction of digital humans in a metaverse, comprising the following structure:

[0022] The information generation unit is used to set the digital human image in the metaverse and the virtual odor information of the digital human, and to generate a virtual odor dispersion area within a preset range of the digital human; the digital human includes the user digital human and other digital humans;

[0023] The information interaction unit is used to display changes in the virtual scent of the user's digital human and / or other digital humans within the virtual scent dispersion area, based on the interactions between the user's digital human and other digital humans. These changes can be displayed through identifiers, which indicate whether the act of other digital humans adding the user's digital human as a friend in the metaverse poses a risk to information security.

[0024] A secure interactive system for digital humans in a metaverse includes:

[0025] Metaverse nodes are used for sending and receiving data;

[0026] The Metaverse Information Security Module is used to ensure information security during digital human interaction.

[0027] System server, which connects to the metaverse node and the metaverse information security module;

[0028] The system server is configured to: set up digital human images in the metaverse and virtual scent information of the digital humans; generate a virtual scent diffusion area within a preset range of the digital humans; the digital humans include user digital humans and other digital humans; based on the interaction between user digital humans and other digital humans, display the change information of the virtual scent corresponding to user digital humans and / or other digital humans within the virtual scent diffusion area; the change information can be displayed through an identifier, which is used to indicate whether the act of other digital humans adding user digital humans as friends in the metaverse will lead to information security risks.

[0029] A computer-readable storage medium storing a computer program, wherein when executed by a processor, the computer program implements the steps of the above-described method for implementing interactive security of digital humans in the metaverse.

[0030] Based on the above advantages and positive effects, the advantages of this invention are as follows: virtual scent enables digital humans to engage in virtual scent-based social interaction in the metaverse. Digital humans can use the virtual scents of other digital humans to identify their intention to make friends and determine whether such intentions could compromise their own information security in the metaverse. Thus, virtual scent-based social interaction in the metaverse attracts digital humans to make friends while ensuring information security. Attached Figure Description

[0037] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a method, apparatus, and system for implementing interactive security of digital humans in a metaverse, as disclosed in this invention. It should be noted that the technical features or combinations of technical features described in the following embodiments should not be considered isolated; they can be combined to achieve better technical effects. In the accompanying drawings of the following embodiments, the same reference numerals in each drawing represent the same features or components, which can be applied to different embodiments. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0038] It should be noted that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art in understanding and reading the invention. They are not intended to limit the conditions under which the invention can be implemented. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of the invention, should fall within the scope of the technical content disclosed in the invention. The scope of the preferred embodiments of the present invention includes other implementations, wherein functions may be performed not in the order stated or discussed, including substantially simultaneously or in reverse order, depending on the functions involved. This should be understood by those skilled in the art to which the embodiments of the present invention pertain.

[0039] Techniques, methods, and apparatus known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and apparatus should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. Example

[0040] See Figure 1 The diagram shown is a flowchart provided by the present invention. The implementation steps S100 of the method are as follows:

[0041] S101, Set up the digital human image in the metaverse and the virtual odor information of the digital human, and generate a virtual odor diffusion area within the preset range of the digital human; the digital human includes the user digital human and other digital humans.

[0042] The metaverse refers to a virtual world constructed by humans using digital technology, which maps to or transcends the real world, allows interaction with the real world, and is a digital living space with a new social system.

[0043] The digital human is a digital image created using computer graphics (CG) technology that closely resembles the human form and is given a specific human identity. This visually shortens the psychological distance between the human and the human, bringing a more realistic emotional interaction to the human.

[0044] The virtual scent can be a comprehensive evaluation obtained by integrating information that reflects the personal characteristics of the digital person in the real world, such as identity authentication information, daily activity preference information, dietary preference information, social preference information, living habits information, and living environment information.

[0045] The virtual odor information refers to information reflecting the aforementioned comprehensive evaluation. The virtual odor information includes virtual location, virtual odor characteristics, virtual odor concentration, and virtual odor duration.

[0046] Taking the aforementioned virtual odor characteristics as an example, rather than a limitation, based on the digital human's real-world information "male, 35 years old, dentist, 180 cm tall, 70 kg in weight, 14% body fat percentage, light diet, enjoys reading, and has little social interaction," in the metaverse, the digital human's virtual odor characteristics are mainly the smell of disinfectant, with the smell of books as a secondary characteristic.

[0047] For example, based on the digital human's information in the real world, "female, 32 years old, coffee shop owner, 165 cm tall, 49 kg in weight, loves socializing and gardening," in the metaverse, the virtual scent characteristics of the digital human are mainly coffee scent, with floral scent as a secondary feature.

[0048] The virtual odor dispersion area is defined by drawing a new outline outward from the outline of the aforementioned digital human image, and the area inside the new outline but outside the outline of the digital human image is set as the virtual odor dispersion area.

[0049] In this embodiment, the delineation can be a proportional enlargement of the outline of the digital human image, or it can be delineated independently.

[0050] S102, based on the interaction between the user's digital human and other digital humans, display the change information of the virtual scent corresponding to the user's digital human and / or other digital humans in the virtual scent diffusion area; the change information can be displayed through an identifier, which is used to indicate whether the behavior of other digital humans adding the user's digital human as a friend in the metaverse will lead to information security risks.

[0051] The virtual odor change information includes virtual odor information at different time points, so as to reflect the changes in virtual odor corresponding to the aforementioned virtual odor information.

[0052] It should be noted that the concentration of the virtual odor can change over time, becoming stronger or weaker; or the virtual odor can be changed over time by adding new virtual odor features to the original virtual odor or ignoring one or more virtual odor features.

[0053] Based on different parts of the digital human, the virtual odor dispersion area can be divided into multiple virtual odor dispersion sub-regions, thereby obtaining virtual odor information within each virtual odor dispersion sub-region.

[0054] Regarding step S102, as an example rather than a limitation, other digital humans 1 and user digital human 2 in the metaverse decide to become friends in the metaverse after interaction and communication. At this time, after other digital human 1 makes a friend request to user digital human 2, user digital human 2 can obtain information about changes in the virtual scent of other digital human 1, and / or, other digital human 1 can obtain information about changes in the virtual scent of user digital human 2.

[0055] It is important to emphasize that the change information can be displayed through an identifier to indicate whether the behavior of other digital humans adding the user's digital human as a friend in the metaverse poses a risk to information security.

[0056] The logo can take the form of color, pattern, expression, or text description.

[0057] When changes are expressed through emojis such as "smiley face," patterns such as "sunny day," or text such as "happy" or "joyful," then the act of user Digital Person 2 adding other Digital Person 1 as friends will not pose a risk to their information security.

[0058] Conversely, when changes are expressed through emojis such as "crying face," images such as "thunderstorm," text such as "unhappy," or text such as "sad," then the act of user Digital Person 2 adding other Digital Person 1 as friends may pose a risk to their information security.

[0059] If adding other Digital Humans 1 as friends by User Digital Human 2 poses a risk to their information security, User Digital Human 2 can either refuse the friend request from other Digital Humans 1, or still add other Digital Humans 1 as friends and receive system alerts about the security risks associated with adding friends, thus ensuring the information security of User Digital Human 2.

[0060] Preferably, the virtual odor dispersion area includes virtual odor information corresponding to various parts of the digital human; the virtual odor dispersion area is defined by drawing a new outline outward from the outline of the aforementioned digital human image, and the area within the new outline but outside the outline of the digital human image is set as the virtual odor dispersion area.

[0061] The body part can be broken down into the head, neck, limbs, and back, etc., so that the digital human image can be divided according to the various parts of the human limbs.

[0062] As an example rather than a limitation, since digital humans are digital images that closely resemble human figures, in the metaverse, the outline of the digital human image is determined based on the user's digital image. At the same time, based on the outline of the digital human image, an outline can be drawn outward to define the area where the digital human's virtual scent can waft.

[0063] The virtual odor-spreading area can be defined proportionally outward from the outline of the digital human image, or it can be defined as a range, such as an outer circle or outer square based on the digital human image, or an area larger than the outer circle or outer square can be set as the virtual odor-spreading area of ​​the digital human.

[0064] It should be noted that the virtual odor dispersion area can be divided into multiple virtual odor dispersion sub-regions based on different parts of the digital human, thereby obtaining virtual odor information within each virtual odor dispersion sub-region.

[0065] Preferably, it involves assessing whether the act of other digital humans adding user digital humans as friends in the metaverse poses a risk to information security.

[0066] It should be noted that the assessment of whether information security risks exist can be approached from multiple perspectives. The preferred approach is to consider the intent of the digital human's request to add friends, and / or to determine the actions performed by the digital human after making historical friend requests, as important references for assessing information security risks.

[0067] The determination specifically includes the following steps:

[0068] S111, compare the first virtual scent information set and the second virtual scent information set; the first virtual scent information set includes the corresponding virtual scent information and / or virtual scent change information when other digital humans add the user's digital human as a friend in the metaverse; the second virtual scent information set includes the historical virtual scent information when other digital humans add other user digital humans as friends during historical interactions, and / or the historical change information of virtual scent.

[0069] Optionally, the comparison in step S111 can also compare the virtual odors of various parts of other digital human 1 during the current interaction and the historical interaction.

[0070] S112, Based on the results of the aforementioned comparison, determine the intent of other digital humans to add the user's digital human as a friend.

[0071] As an example rather than a limitation, there exist other digital humans 1, user digital humans 2, other user digital humans 3, other user digital humans 4, and other user digital humans 5 in the metaverse.

[0072] When another digital human 1 sends a friend request to user digital human 2, the information in the first virtual scent information set and the second virtual scent information set can be compared. By comparing the information in the first virtual scent information set and the second virtual scent information set, the intention of the other digital human 1 to request to add user digital human 2 as a friend can be determined.

[0073] For example, if Other Digital Person 1 is a lively and cheerful digital persona, and the virtual scent information of Other Digital Person 1 currently adding User Digital Person 2 as a friend is consistently positive compared to the virtual scent information of Other Digital Person 1 when adding User Digital Person 3, User Digital Person 4, or User Digital Person 5 as friends in previous interactions, then it can be determined that Other Digital Person 1's current intention to request User Digital Person 2 to become a friend is normal.

[0074] At this point, it can be considered that other digital human 1 is requesting to add user digital human 2 as a friend, without any information leakage or other operations that could endanger the information security of user digital human 2.

[0075] For example, another digital human, 1, is the avatar of a skilled hacker. Their usual practice is to add other digital humans as friends to obtain more personal information. In this situation, although the virtual scent information of another digital human currently adding user digital human 2 as a friend is consistent with the virtual scent information when they added other user digital human 3, other user digital human 4, or other user digital human 5 as friends in previous interactions, the presence of negative reviews or warnings indicates that other digital human 1's current request to add user digital human 2 as a friend is suspicious.

[0076] At this point, if another digital human 1 requests to add user digital human 2 as a friend, it may subsequently leak user digital human 2's information security, thus threatening user digital human 2's information security.

[0077] S113, Based on the pre-set correspondence between digital human behavior and information security risk in the metaverse information security database, determine the information security risk corresponding to the digital human requesting to add friends.

[0078] As an example, not a limitation, if in the metaverse, after other digital human 1 and user digital human 2 interact and communicate, and when other digital human 1 makes a friend request to user digital human 2, it is determined that the intention of other digital human 1 in adding the friend request is to obtain more personal privacy information of digital human 1 for resale or dissemination, then the information security risk level of user digital human 2 adding other digital human 1 as a friend is high. In this case, the friend request of other digital human 1 can be rejected to protect the information security of user digital human 2.

[0079] Alternatively, the information security risk of adding another digital person (user 1) as a friend can be determined by analyzing their past actions after requesting to add them as friends. For example, if another digital person 1 has spread false information about other digital persons when requesting to add other users (user 3, 4, and 5), then the information security risk level of adding another digital person 1 as a friend is high. In this case, user 2 can reject that digital person's friend request to protect their own information security.

[0080] The correspondence between the digital human's behavior and information security risks can be preset.

[0081] For example, if a digital human collects personal information from other digital humans, then the information security risk posed by that digital human to other digital humans is serious; similarly, if a digital human promotes or resells government-banned goods under the guise of making friends, then the information security risk posed by that digital human to other digital humans is serious; if a digital human does not collect personal information from other digital humans, then the information security risk posed by that digital human to other digital humans is minor, and so on.

[0082] It is important to emphasize that the changes in the virtual scent can reflect changes in the digital person's overall evaluation when communicating and interacting with others in the real world. This change information can be displayed using identifiers to indicate whether the actions of other digital persons adding the user's digital persona as a friend in the metaverse pose a risk to information security.

[0083] The advantage of performing the above operations is that virtual scents enable digital humans to engage in virtual scent-based social interaction within the metaverse. Digital humans can use the virtual scents of other digital humans to discern their intentions to make friends and determine whether such intentions could compromise their own information security within the metaverse.

[0084] Preferably, if the aforementioned intention to add friends is deemed normal, the following steps are further performed to identify situations where what appears normal is actually abnormal, specifically including:

[0085] S1121, Obtain the basic information of the other digital humans who requested to add you as friends as the first information.

[0086] The basic information refers to information other than the aforementioned virtual scent information, including one or more of the following: digital human image, digital human name, digital human motto, and digital human privacy information.

[0087] S1122, based on the first information, retrieve basic information in the metaverse that matches the first information to a preset threshold as the second information.

[0088] The compatibility level can be preset by the user or the metaverse administrator.

[0089] The threshold can be set, for example, to a preset threshold when the degree of matching between the first information and the second information reaches 90%.

[0090] It should be noted that the second piece of information is the basic information of digital humans excluding the other digital humans mentioned above.

[0091] S1123, then based on the second information, obtain the corresponding digital human account, obtain the communication interaction information between the digital human account and other digital humans who requested to add each other as friends, the account online time and / or the account online location, in order to determine the degree of correlation between the two.

[0092] The correlation can be determined by information such as the communication interaction information between the digital human account obtained from the second information and the aforementioned digital human who requested to add friends, the account's online time and / or the account's online location.

[0093] The correlation degree can be set to strong correlation, general correlation, and weak correlation, and corresponding thresholds can be set for the aforementioned strong correlation, general correlation, and weak correlation.

[0094] For example, we can set the correlation (90%, 100%) as a strong correlation, the correlation (50%, 90%) as a moderate correlation, and the correlation [0%, 50%] as a weak correlation. Under a strong correlation, we can conclude that the aforementioned digital human account is a related account of the other digital human who requested to add us as a friend.

[0095] S1124, when the correlation reaches the threshold, the aforementioned digital human account is determined to be an associated account of the other digital human who requested to add friends.

[0096] The associated account can be one person in the real world corresponding to multiple digital people in the metaverse, and these digital people are managed by the same person.

[0097] S1125, determine whether the associated account is in the preset blacklist of accounts.

[0098] The blacklisted accounts can also be pre-set by users or metaverse administrators. For example, if the aforementioned digital human account has multiple negative reviews or warnings in its history of making friends, after accumulating a certain number of times, the digital human account can be added to the blacklist. Furthermore, based on the fact that the digital human account is associated with the aforementioned other digital human accounts, it can be determined that the other digital human's intention to add friends is abnormal.

[0099] S1126, when it is determined that the account is in the blacklist, update the friend request intention of other digital users who requested to add friends to the status as abnormal.

[0100] As an example, and not a limitation, this applies when there are other digital humans in the metaverse, such as Digital Human 1, User Digital Human 2, and multiple digital humans like Digital Human 3 and Digital Human 4.

[0101] When another digital human 1 requests to add user digital human 2 as a friend, if the intention of the other digital human 1 to add the friend is judged by virtual scent information and the intention to add the friend is normal, then it is possible to further judge whether the intention of the other digital human 1 to add the friend is pseudo-normal, that is, a situation where it pretends to be normal but is actually abnormal.

[0102] Using the basic information of other digital humans 1, i.e., the first information, basic information that matches the first information to a preset threshold is retrieved in the metaverse as the second information. For example, if the preset threshold for matching is 90%, there are two sets of second information that meet this threshold. Based on the second information, the corresponding digital human accounts can be identified as digital human 3 and digital human 4.

[0103] At this point, the communication interaction information, account online time and / or account online location of digital human 3 and digital human 4 with other digital human 1 who requested to add each other as friends are obtained to determine the degree of association between digital human 3 and other digital human 1, and between digital human 4 and other digital human 1.

[0104] Further analysis of the correlation between Digital Person 3 and other Digital Person 1, and between Digital Person 4 and other Digital Person 1, reveals that Digital Person 3 has a 95% correlation with other Digital Person 1 (i.e., a strong correlation), and Digital Person 4 has a 25% correlation with other Digital Person 1 (i.e., a weak correlation). Therefore, it is concluded that Digital Person 3 is an associated account of other Digital Person 1.

[0105] Next, it is determined whether the associated account (digital human 3) is in the preset blacklist of accounts. If it is determined to be yes, the friend request intentions of other digital humans that have requested to add friends are updated to abnormal.

[0106] The advantage of executing steps S1121-S1126 is that it can identify situations that are disguised as normal but are actually abnormal, even when the aforementioned intention to add friends is normal. This is to prevent the user's personal information security from being exposed to risks after the user's digital person adds other digital people as friends.

[0107] Preferably, the virtual odor information includes virtual location, virtual odor concentration, and virtual odor duration information; the virtual odor information can be adjusted by adding virtual perfume; the virtual perfume is pre-set according to the perfume type, perfume characteristics, and perfume quality in the real world, and is stored in the metaverse odor information database accordingly.

[0108] The virtual location can be customized to set the position of the digital human in the metaverse, or it can be preset by the system.

[0109] The virtual odor concentration can be displayed numerically as the value of the virtual odor concentration of each part of the digital human within the aforementioned virtual odor dispersion area.

[0110] Optionally, the area where the virtual odor is closest to the digital human's outline reflects the strongest odor, and the corresponding value is set to the maximum; conversely, it is set to the minimum if the odor is further away from the outline.

[0111] Furthermore, it is worth noting that the changes in the numerical values ​​can also form a data point on their own. The changes in the numerical values ​​can reflect the changes in the area where the user's virtual odor diffuses. Alternatively, different colors can be used to represent the numbers, and the intensity of the colors can be used to determine the area of ​​change in the numerical value of the virtual odor diffuse area, as well as the degree of change in the concentration of the virtual odor emitted in that area.

[0112] The duration of the virtual odor reflects the length of time the current digital person stays in the metaverse.

[0113] Optionally, the virtual odor information corresponds to different odor concentration levels for different locations within the area.

[0114] The virtual odor information can be represented by numbers to indicate the odor concentration values ​​at various locations within the virtual odor dispersion area of ​​the digital human.

[0115] When multiple digital beings interact in the metaverse and bring them closer in their communication within the metaverse, the numerical changes in the virtual scent information corresponding to the multiple digital beings are obtained. Based on the numerical changes corresponding to these concentration values, the sensitivity of the digital beings to other digital beings they are interacting with is determined, thereby allowing them to choose to receive and / or send friendship information.

[0116] It should also be noted here that digital humans can adjust their virtual scent by using virtual perfume on themselves.

[0117] As an example, and not a limitation, considering the use of perfume, which is most commonly sprayed on the wrists, behind the ears, and head, the virtual scent diffusion sub-regions are designated for the digital human image, corresponding to the head, neck, hands, and hair. The virtual scent information within each sub-region is recorded.

[0118] Ideally, from the perspective of olfactory psychology, the virtual scent of each digital human should correspond to its personality traits. By spraying virtual perfume, the most prominent personality characteristics of a digital human's virtual scent can be displayed to other digital humans.

[0119] For example, people who like woody perfumes tend to be strong-willed and introverted. Such people often adhere to certain rules and principles in their interactions with others.

[0120] For example, people who like the smell of fruit are often positive, optimistic, and outgoing—typical extroverts. They are straightforward in their interactions, efficient in their work, hate procrastination, are bold, unafraid of risks and challenges, and are full of interest in new things, able to quickly accept and master them.

[0121] Optionally, based on the fragrance family classification, virtual perfumes can be categorized into four types: aromatic, fresh, classic, and rich. Each type further includes different virtual perfume base notes.
