ABSTRACT:
A retrieval system includes a retrieval server for providing retrieval service and a retrieval device accessible through a transmission medium by the retrieval server. The retrieval device is configured to modify a first retrieval condition with a first retrieving extent into a second retrieval condition with a second retrieving extent which includes the first retrieving extent and which is greater than the first retrieving extent. The server retrieves first retrieved information under a second retrieval condition. The retrieval device retrieves second retrieved information from the first retrieved information under a first retrieval condition designated by a user. The first retrieval condition includes a first factor in connection with the user's privacy-related information. The first retrieval condition includes a second factor corresponding to the first factor. The second factor has a greater retrieving extent than the first factor for protection of the user's privacy-related information.
