INFORMATION PROCESSING SYSTEM AND DATA PROCESSING METHOD THEREFOR

摘要

The present invention provides a system for realizing both the operation of archive and sharing of contents capable of maintaining a privacy policy of critical data. In order to realize the system, a disclosure condition to a data reference destination and a data conversion method of the file data are designated, and only the file data matching the disclosure condition is provided to the data reference destination by anonymizing the file data via the data conversion method. When the disclosure condition or the data conversion method is changed, an already disclosed file data is deleted, or replaced with the file data subjected to data conversion after the change.

主权项

1. An information processing system comprising a plurality of sub-computer systems including a first sub-computer system and a second sub-computer system for providing a stored file data to a client computer, and a data management computer system connected to the plurality of sub-computer systems;
the data management computer system comprising: a storage system; wherein the data management computer system stores a file data migrated from the plurality of sub-computer systems in the storage system; stores a file data disclosure rule to the second sub-computer system regarding a migration file data from the first sub-computer system; the file data disclosure rule including a data disclosure condition and a data conversion method of the file data; determines whether reference is possible or not based on the data disclosure condition when a reference request is received from the second sub-computer system to a migration file data from the first sub-computer system; provides the file data having been converted via the data conversion method to the second sub-computer system when reference is enabled; and deletes the file data provided to the second sub-computer when the file data disclosure rule has been changed.
