Abstract: The present invention includes a memory and a processor configured to store, in a storage, a first digital twin in which at least one model defining at least one function of an entity at a given time, and at least one piece of second data that includes, as a constituent element, first data for realizing the function of the entity due to being input to the model are included, create at least one second digital twin by performing predetermined first computation using, as a computation target, at least one first digital twin stored in the storage, and execute computation for arranging the second digital twin in a sandbox for which a predetermined time axis has been set, and realizing a function of an entity indicated by the second digital twin in the sandbox in accordance with the time axis.

Abstract: An information management device includes a memory, and processing circuitry coupled to the memory and configured to convert said spatio-temporal information in storage object information into a one-dimensional bit string, split the converted one-dimensional bit string into an upper bit string and a lower bit string, and cause a storage target node to store at least the split upper bit string in a key and to store the split lower bit string and said associated data in a value of that key, and convert a range condition of spatio-temporal information of an object to be retrieved into one-dimensional bit string, split the converted one-dimensional bit string into an upper bit string and a lower bit string, retrieve a key from a search target node using at least the split upper bit string, and retrieve a value corresponding to the split lower bit string from values of the retrieved key.

Abstract: An original data circulation system for storing or circulating original data which is digital information is provided. The original data circulation system includes an issuer apparatus, a user apparatus and a collector apparatus. The issuer apparatus generates originality information including first information corresponding to the issuer apparatus and second information corresponding to data and sends the originality information. The user apparatus verifies the validity of the source apparatus of the originality information and stores the originality information when the validity is verified. The collector apparatus verifies the validity of the source apparatus of the originality information and processes data corresponding to the second information when the validity is verified.
