Abstract

A semiconductor integrated circuit device for use in a data communication apparatus includes setting means for setting, for each of a plurality of files that the semiconductor integrated circuit device manages, a flag indicating whether definition information functioning as information on each of the plurality of files is browsable or not browsable; and response sending means for sending, when provision of the definition information on a file is externally requested, a response falsely indicating that the semiconductor integrated circuit device is not managing the file existing in the plurality of files according to the flag set for the file indicating that the definition information on the file is not browsable.

Claims

1. A semiconductor device comprising:

a tangible non-transitory computer-readable memory configured to store a folder of files, a service being one of the files;

a processing unit configured to execute a computer program, said computer program instructing said processing unit to execute;

a step of determining a service access status, a service-no-browse indication being produced when said service access status restricts access to said service by an electronic device;

a step of determining a folder access status, a folder-no-access indication being produced

when said folder access status restricts access to said folder by said electronic device;

a step of producing a non-registration indication when either said service-no-browse indication or said folder-no-access indication has been produced, said non-registration indication falsely indicating an absence of said service from within said folder even when said service exists in said folder,

wherein said non-registration indication is produced when said service is absent from said memory,

wherein said folder-no-access indication is producible only when said service access status permits access to said service by said electronic device.

2. The semiconductor device set forth in claim 1, wherein receipt of said non-registration indication by said electronic device prohibits access of said electronic device to said service.

3. The semiconductor device set forth in claim 1, wherein said computer program instructs said processing unit to execute:

a step of receiving a command from a computer-readable network, said command being sent from said electronic device;

a step of transmitting said non-registration indication, said non-registration indication being a reply to said command.

4. The semiconductor device set forth in claim 1, further comprising:

an input unit configured to receive said service access status and said folder access status.

5. The semiconductor device set forth in claim 1, wherein said service access status is stored within said service.

6. The semiconductor device set forth in claim 1, wherein said folder access status is stored within said folder.

7. The semiconductor device set forth in claim 1, wherein said service-no-browse indication is producible only when said service is exists in said memory.

8. The semiconductor device set forth in claim 1, wherein said computer program instructs said processing unit to execute:

a step of producing a registration indication when neither said service-no-browse indication nor said folder-no-access indication has been produced.

9. The semiconductor device set forth in claim 8, wherein receipt of said registration indication by said electronic device permits access of said electronic device to information within said service.

10. The semiconductor device set forth in claim 1, further comprising:

a communication unit configured to provide communication with said electronic device.

11. The semiconductor device set forth in claim 10, wherein said communication is wireless communication.
