摘要： A file editing system that provides a high file content secrecy, a file version management, and an asynchronous editing is disclosed. For a high file content secrecy, the block data of files managed by a file management server device are enciphered in units of blocks, and a client device obtains the block data of the desired file in enciphered state, deciphers the obtained block data in units of blocks, carries out an editing of the desired file to obtain editing data, enciphers the editing data in units of blocks, and transmits the enciphered editing data to the file management server device. For asynchronous editing, the system includes a unit for generating editing procedure data that indicates a procedure to obtain the editing made in the desired version of the desired file by each client device, a unit for converting the editing procedure data for the desired version of the desired file into converted editing procedure data for the latest version of the desired file, and a unit for generating record management information indicating a result of the editing made by each client device according to the converted editing procedure data for the latest version of the desired file.
