3D data system, server, and methods of handling 3D data

A server comprising:

• a processor;
• and
• a memory operably connected to the processor,
• wherein the processor is configured to
• store, in the memory, for each of a plurality of 3D data sets, a correspondence between a user who is a subject of a 3D model and another user with whom the 3D data set is shared, each 3D data set including a data body, share restriction information, and process restriction information, the data body representing a 3D model, the share restriction information describing restrictions on sharing the data body, and process restriction information describing restrictions on processing the 3D model;
• receive from a service application a processing request, which is a request to process the 3D data set, and includes a user identifier;
• a authenticate the user who sent the processing request to perform the process, based on the correspondence stored in the memory and the share restriction information included in the 3D data set;
• and
• transmit at least a part of the data body and at least a part of the process restriction information to the service application in response to the processing request in a case that the user who sent the processing request is authenticated to perform the processing,
• in a case that the processing request is a share request, which is a request for sharing the 3D data set with another user, the share request including a user identifier of a share source user and a user identity of a share destination user, the processor is configured to authenticate sharing of the 3D data set from the share source user to the share destination user based on the share restriction information stored in the memory, and
• the processor is further configured to cause the memory to store information that the 3D data set has been shared from the share source user with the share destination user in a case that sharing the 3D data set from the share source user to the share destination user is authenticated.

A 3D data processing method comprising:

• transmitting, by a client terminal, a processing request to a server, the processing request being a request for processing a 3D data set, the 3D data set including a data body, share restriction information, and process restriction information, the data body representing a 3D model, the share restriction information describing a restriction on a scope for sharing the data body, the process restriction information describing a restriction on the processing of the 3D model, the processing request including a data identifier for identifying the 3D data set and a user identifier for identifying the user;
• storing, by the server, in a memory, correspondence among the data identifier of the 3D data set, the user identifier of the user who is a subject in the data body included in the 3D data set, and the user identifier of the user who shares the 3D data set from the user;
• receiving, by the server, the processing request from the service application;
• authenticating, by the server, to perform the processing related to the processing request based on the correspondence stored in the memory and the share restriction information included in the 3D data set;
• transmitting, by the server, in response to the processing request, at least a part of the data body and at least a part of the process restriction information to the service application, in a case that performing the processing is authenticated;
• receiving, by the client terminal, the response from the server;
• processing, by the client terminal, the data body within the restrictions of the process restriction information;
• and
• outputting, by the client terminal a result of the processing,
• in a case that the processing request is a share request, which is a request for sharing the 3D data set with another user, the share request including a user identifier of a share source user and a user identity of a share destination user, the authenticating further includes authenticating sharing of the 3D data set from the share source user to the share destination user based on the share restriction information stored in the memory, and
• further comprising causing, by the server, the memory to store information that the 3D data set has been shared from the share source user with the share destination user in a case that sharing the 3D data set from the share source user to the share destination user is authenticated.
