DATA MANAGEMENT METHOD AND SYSTEM, AND APPARATUS USED THEREIN
First Claim
1. A data management method, comprising:
- providing a plurality of information units, each information unit being a part of a base information and carrying information representing one of various items in said base information, said base information being provided to an information recipient by a unidirectional communication system from an information provider;
generating, by a first communications device which is associated with an information recipient, an information recipient verification data that identifies the information recipient and an identifying data that identifies the information unit selected by the information recipient,receiving, at an information manager from the first communications device, the information recipient verification data and the identifying data that identifies the information unit selected by the information recipient;
storing in a first database the identifying data and the information recipient verification data in a linked manner, when the information manager receives the identifying data and the information recipient verification data;
storing in a second database the identifying data and a reference data in a linked manner, said reference data defining features of the information unit corresponding;
sending the information recipient verification data from a second communications device to the information manager; and
accessing from the second communications device to the first database to find the information recipient verification data and the linked identifying data, and further accessing from the first database to the second database to find the corresponding identifying data and the linked reference data, whereby the second communications device is able to receive the linked reference data.

Abstract
An information unit carries information representing an item in base information provided unidirectionally to an information recipient from an information provider. The unit is part of the base information. A first communications device generates an information recipient verification data for an information recipient and an identifying data for the unit selected by the recipient. An information manager receives the verification data and the identifying data from the first device. The identifying data and the verification data are stored and linked in a first database. The identifying data and a reference data are stored and linked in a second database. The reference data defines features of the corresponding unit. Another communications device forwards the verification data to the information manager to access the first database and find the identifying data, and the first database accesses the second database to obtain the reference data, whereby the other can receive the reference data.

22. A data management system, comprising:
-
an arrangement which provides a plurality of information units, each information unit being a part of a base information and carrying information representing one of various items in said base information, said base information being provided to an information recipient by a unidirectional communication system from an information provider; a first communications device which is associated with an information recipient and generates an information recipient verification data that identifies the information recipient and an identifying data that identifies the information unit selected by the information recipient; an information manager which receives from the first communications device the information recipient verification data and the identifying data; a first database which stores the identifying data and the information recipient verification data in a linked manner, when the information manager receives the identifying data and the information recipient verification data; a second database which stores the identifying data and a reference data in a linked manner, said reference data defining features of the information unit; a second communications device which sends the information recipient verification data to the information manager; and a controller which controls accessing from the second communications device to the first database to find the information recipient verification data and the linked identifying data, and further accessing from the first database to the second database to find the corresponding identifying data and the linked reference data, whereby the second communications device is able to receive the linked reference data.
