摘要：
An electronic data management system capable of preventing confusion due to transfer of electronic data, even if electronic data attached with original attribute is transferred is provided. This system includes a transfer source server and a transfer destination server connected via a network. The transfer source server retains electronic data having attribute information attached indicating that the electronic data is the original. The transfer source server duplicates the electronic data to create new electronic data and stores the same in conjunction with information indicating that the new electronic data is a duplicate and information identifying the transfer destination server to which the original has been transferred.
