Abstract

A terminal device reliably controlling the usage right with improved convenience is provided. The terminal device reads out a medium identifier held in a computer-readable content recording medium. Usage rights information for each content held in a computer-readable usage rights recording medium is read out, and the usage rights information read out from the usage rights recording medium is set unusable. Authentication information including the readout medium identifier and at least part of the usage rights information for each content is produced and stored, and the stored authentication information is subjected to a predetermined process for determining whether or not to grant access to the content held in the content recording medium.

Claims

1. A method of controlling a terminal device capable of reading information from a usage rights recording medium located close thereto in a readable range, comprising:

a step of causing the usage rights recording medium to record usage rights information corresponding to content to be processed;

a step of setting a content recording medium storing the content in the terminal device, and instructing initiation of a process; and

a step of bringing the usage rights recording medium recording the usage rights information corresponding to the content close to the terminal device in the range readable by the terminal device, causing readout, and receiving from the terminal device a setting for rendering unusable the usage rights information recorded in the usage rights recording medium.

2. A method of controlling a terminal device, comprising:

a step of reading a medium identifier held in a computer-readable recording medium;

a step of reading usage rights information for each content held in the computer-readable recording medium, and setting the usage rights information read out from the recording medium to unusable; and

a step of producing and storing authentication information including the readout medium identifier and the usage rights information for each content;

wherein

the stored authentication information is subjected to a predetermined process for determining whether or not to grant access to the content held in the recording medium.

3. A control method according to claim 2, wherein

when the content recording medium is received, the medium identifier held in the content recording medium is referred to, and a process of requesting a user to enter usage rights information is performed if the authentication information related to the medium identifier is not stored.

4. A control method according to claim 2, wherein

the terminal device includes an IC card reader/writer unit for accessing an IC card and reading and writing data, and

the usage rights recording medium is an IC card reader, and access to the usage rights information is made through the IC card reader/writer.

6. A control method according to claim 2, wherein

the content includes a plurality of content elements,

the usage rights information includes information specifying an accessible content element among the plurality of content elements, and

the stored authentication information is subjected to a predetermined process for determining whether or not to grant access to each content element of the content held in the recording medium.

8. A control method according to claim 2, wherein

when the content recording medium is received, the medium identifier held in the content recording medium is referred to, and, if the authentication information related to the medium identifier is stored, access is made to the content based on the usage rights information included in the authentication information.

10. A control method according to claim 2, wherein

the authentication information further includes a terminal identifier assigned uniquely to the terminal device, and

if the terminal identifier of the stored authentication information does not match its own terminal identifier, an authentication process based on the authentication information is controlled not to be performed.

5. A method of controlling a terminal device, comprising:

a step of reading a medium identifier held in a computer-readable content recording medium;

a step of reading usage rights information for each content held in the content recording medium, and setting unusable the usage rights information read out from the content recording medium; and

a step of producing and storing authentication information including the readout medium identifier and the usage rights information for each content;

wherein

the stored authentication information is subjected to a predetermined process for determining whether or not to grant access to the content held in the content recording medium.

7. A control method according to claim 5, wherein

the content includes a plurality of content elements,

the usage rights information includes information specifying an accessible content element among the plurality of content elements, and

the stored authentication information is subjected to a predetermined process for determining whether or not to grant access to each content element of the content held in the recording medium.

9. A control method according to claim 5, wherein

when the content recording medium is received, the medium identifier held in the content recording medium is referred to, and, if the authentication information related to the medium identifier is stored, the content is accessed based on the usage rights information included in the authentication information.

11. A control method according to claim 5, wherein

the authentication information further includes a terminal identifier assigned uniquely to the terminal device, and

if the terminal identifier of the stored authentication information does not match its own terminal identifier, an authentication process based on the authentication information is controlled not to be performed.

12. A terminal device, comprising

a device for reading out a medium identifier held in a computer-readable content recording medium;

a device for reading out usage rights information for each content held in the computer-readable usage rights recording medium, and setting unusable the usage rights information read out from the usage rights recording medium; and

a device for producing and storing authentication information including at least part of usage rights information for each content and the readout medium identifier;

wherein

the stored authentication information is subjected to a predetermined process for determining whether or not to grant access to the content held in the content recording medium.
