[0044] S2, the global device management server accesses the physical Internet of Things devices;

[0045] In an embodiment, in the step of the global device management server accessing the physical Internet of Things devices, first, for a specific Internet of Things device model, the division of atomic operations is completed, forming an operation set, then the atomic operations in the operation set are arranged and combined to form a scene set, subsequently, according to the scene set, the user data specification definition and the virtual device metadata definition are set, forming a virtual device description file, the global device management server creates a virtual device for the accessed physical device, the virtual device contains all the scene set and initial user data, which is used as the root node of the subsequent virtual device tree, and the initial user is the device administrator.

[0046] Specifically, the definition and creation of the virtual device:

[0047] For a specific Internet of Things physical device, according to its operation function, the atomic function is combed and split to form an atomic function set, denoted as OSet:

[0048] OSet={op1,op2,...,op i};

[0049] Wherein, op i ​The executable operations, such as turning on the device, turning off the device, etc., each operation in OSet can be executed independently, but there are allowed dependencies (such as the device can only be turned off after being turned on).

[0050] For a specific Internet of Things physical device, according to its operating function, define its global state data, denoted as S. The state data S is a matrix used to manage the basic information of the device, such as device signal strength, power, switch state, etc. At the same time, for the user data managed by the device, define the user information set DSet:

[0051] DSet={D1,D2,...,D i};

[0052] Where D i represents the matrix of each user information managed by the device, i.e. D i and D j are data belonging to completely independent subjects, such as user fingerprints, mobile phone numbers, etc. D i and D j can also be set as different range data of the same user, such as desensitized photos and original photos, etc.

[0053] The matrix structure and data definition of D i and D j are consistent. For a specific user data, denoted as D. At this point, a subject's specific operation on a physical device can be expressed as: op i (S, D). Where S can be empty, i.e. the operation can not interact with the global device information, such as pressing the switch, but it does not need to know whether the device is turned on after the switch operation.

[0054] According to the device functions that need to be opened in the meta-universe business scenario, design the operation scenario, and the operation scenario set is denoted as ASet.

[0055] ASet={A1,A2,...,A i};

[0058] Obtain the user's authorization data, corresponding to D i user data;

[0059] According to the business context, determine the scene A x that the user can operate;

[0060] According to A x Determined op i Confirm whether to contain global state data S;

[0062] Virtual device creation is completed, and its elements include device scene A x User data D i Device metadata, global state data S (may be empty).

[0063] Use of virtual device:

[0064] The user updates or enters his personal data, and the data is synchronized to the virtual device under his name;

[0065] The user selects the virtual device and performs the operation op i Its corresponding op i (S, D) process is sent to the physical device for actual execution;

[0066] After the physical device performs the operation, the corresponding S and D change, and the user obtains the results.

[0069] Referring to Figure 2 the schematic diagram of the creation process of the virtual device and Figure 3 the schematic diagram of the virtual device data structure; virtual device authorization and secondary creation:

[0070] For the virtual device owned by the user subject, obtain its device scene and user data;

[0071] User selects authorized content, authorized operation is a subset of device scene, but needs to exist in the physical device scene set;

[0072] User selects authorized data content, which is a subset of personal data, and checks the compatibility of the device scene subset and the personal data subset, i.e. the operation is executable within the authorized data range;

[0073] For authorized users, combine their personal data with the authorized data subset to form a new personal data set;

[0074] According to the scene subset, the new personal data set, define device metadata, and create a new virtual device.

[0075] S4, the global device management server completes the virtual device creation;

[0076] In an embodiment, in the step of completing the virtual device creation by the global device management server, the global device management server receives a virtual device creation request, first verifies the virtual device unique identifier in the request against the signature of the authorized principal to authenticate, ensures the request legality, secondly verifies the matching of the operation set and the data set in the request, ensures the operation and data function have execution on the device, after verification success, uses depth traversal to locate the authorized principal's virtual device in the virtual device tree, adds a leaf node virtual device under it, the leaf node contains the device operation set in the request, virtual device metadata, personal principal and signature information of the authorization process, the device ownership belongs to the principal of the request virtual device.

[0081] For each user, a corresponding virtual device is generated, which is the first layer tree node, and for the second authorized device of the user and the third authorized device, the nodes are continuously generated along the branch of the corresponding tree until the nth time;

[0082] For each node of the global virtual device tree, when the user data and global device data change, the corresponding data of the child node is changed, and the actual operation interaction of the virtual device corresponding to the child node with the user is performed;

[0083] When a certain node is deleted, the corresponding child nodes are all deleted first, and then the node itself is deleted, and the virtual device deletion information corresponding to the node is no longer available to the user.

[0084] Among them, the natural person with data ownership is taken as the granularity, which is the finest division, the virtual device can be infinitely divided on the physical device, the user can authorize others to use the virtual device, the data flow process is clear, and there is a strict permission traceability relationship.
