DATA READING DEVICE AND ITS METHOD

摘要

A server (2) authenticates a user A. When a user B makes a processing request (a), the server (2) starts filtering of object data a1 used for the processing requested by the user B. The server (2) conducts the requested processing and reads the object data a1 out of a DB unit (36). The server (2) conducts filtering of the object data a1 using a preset security mask, and sends as a reply to the user B only element data a2 (client name) to which the user B is permitted to access in respect to the security mask out of element data (client name, client address, and client telephone number) included in the object data a1.
