Data filing system

摘要

An arrangement for filing and retrieving data of a plurality of mutually remote data sources which are connected to a remote central file-storage system by a public, wide-area transmission network. Mutually separable storage fields are maintained in the central file-storage system by allocating separate storage fields to the data of each of the remote data sources by a user filter coupled to the file storage system to ensure that every user can transfer in the central file system only in his field. An access authorization code transmitted from a remote data source is compared to an access code stored in the file-storage system to permit access by a remote data source to the separate storage fields allocated to the data source seeking access.
