AI Technical Summary

Problems solved by technology

The problem is that everyone must have their own IC card
Even if everyone has an IC card, it cannot be determined whether the user of the IC card is actually the owner of the IC card
The problem is that people under the specified age can use the IC card of other people above the specified age without permission to revoke the encryption of age-restricted programs

[0068] figure 1 The structural principle of the pay television system according to the first embodiment of the present invention is shown. The pay television system 1 is mainly divided into a transmitting side and a receiving side. The broadcasting station 900 is arranged on the sending side. The receiving side is equipped with a decryption module 200 , an IC card 100 for pay TV, and a TV set 300 .

[0069] On the transmitting side, the broadcasting station 900 transmits the encrypted program attribute signal 203 and the video-audio encrypted signal 201 . Radio or cable can be used as the transmission medium. In the case of a television program with a prescribed age restriction, the encrypted program attribute signal 200 includes program target age information indicative of the prescribed age restriction. In addition, information for revoking the encryption key of the video-audio encrypted signal may be included.

[0070] The video-audio encrypted signal 201 is encrypted ...

[0182] In the foregoing first embodiment, pay television IC card 100 and decryption module 200 are provided as separate units. In the second embodiment of the present invention, pay television IC card 100 and decryption module 200 are integrally formed as decryptor 400 .

[0183] The decryptor of the second embodiment is provided by a pay television service provider when a subscriber who is to receive the service of the pay television system applies for authorization to watch a pay television program. The pay television service provider and the subscriber's service number record the date of birth information and the secret identification code in the storage unit 120 accordingly, before handing over the decryptor to the subscriber.

[0184] Figure 9 is a block diagram of the principle structure of the decryptor of the second embodiment. see Figure 9 , the decryptor 400 includes a control unit 110 for controlling the entire decryptor 400, a broadcast information input unit ...

[0205] see Figure 11 According to the pay TV system 910 of the third embodiment of the present invention, it includes server devices 700A, 700B and 700C, one master registration device 800 and seven decryption modules 200A, 200B, 200C, 200D, 200E, 200F and 200G.

[0206] Although Figure 11 3 server devices 700A, 700B and 700C, master registration device 800 and decryption modules 200A, 200B, 200C, 200D, 200E, 200F and 200G are shown, but the number of these units is arbitrary as long as there is at least one duplicate unit.

[0207] In pay television system 910 of the third embodiment, the number of uses of pay television IC card 100A is managed by any one of server devices 700A, 700B, and 700C. For the sake of simplification, the following description will only be made based on the management of the server device 700A. The usage quantity of the pay television IC card 100A is managed according to the permitted usage quantity specified when the pay television IC card 100A ...

Abstract

A pay television IC card includes a storage unit prestoring fingerprint information that allows identification of a registrant, a fingerprint information input unit accepting input of physical description data of a user, a comparison determination unit comparing fingerprint information accepted by the fingerprint information input unit with fingerprint information stored in the storage unit to determine whether the user is the registrant, and a descramble key generation unit providing a descramble key based on the determination result by the comparison determination unit. A descramble key is output by determining whether the user and the registrant are the same person based on fingerprint information, and determination of the sameness between the user and the registrant is established.

Description

technical field [0001] The present invention relates to an IC card, an authorized individual identification method, an authorized individual identification program, a computer-readable recording medium on which the authorized individual identification program is recorded, and a decryptor which can have limited users. The present invention also relates to an authorized individual registration method, an authorized individual registration program, and a computer-readable recording medium recorded with the authorized individual registration program allowing authorized individual registration. Furthermore, the present invention relates to a server device, a management method, a computer-readable recording medium in which a management program is recorded, and a physical description reader for managing the usage-allowed number of IC cards. Background technique [0002] Satellite broadcasting systems are known which transmit pay television information via satellite and receive the ...
