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 integrated circuit device for use in a data communication apparatus, the semiconductor integrated circuit device comprising:

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.

2. The semiconductor integrated circuit device according to claim 1, wherein:

the setting means also sets a flag designating a requester who requests provision of the definition information; and

when the provision of the definition information is requested from the requester designated by the flag set by the setting means, the response sending means sends the response falsely indicating that the semiconductor integrated circuit device is not managing the file.

3. An information processing method comprising the steps of:

setting, for each of a plurality of managed files, a flag indicating whether definition information functioning as information on each of the plurality of files is browsable or not browsable; and

sending, when provision of the definition information on a file is externally requested, a response falsely indicating that the file existing in the plurality of files is not being managed according to the flag set for the file indicating that the definition information on the file is not browsable.

4. A program for causing a computer to perform a process comprising the steps of:

setting, for each of a plurality of managed files, a flag indicating whether definition information functioning as information on each of the plurality of files is browsable or not browsable; and

sending, when provision of the definition information on a file is externally requested, a response falsely indicating that the file existing in the plurality of files is not being managed according to the flag set for the file indicating that the definition information on the file is not browsable.

5. A portable terminal comprising:

a semiconductor integrated circuit device for use in a data communication apparatus, the semiconductor integrated circuit device including

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.

6. A semiconductor integrated circuit device for use in a data communication apparatus, the semiconductor integrated circuit device comprising:

a setting unit that sets, 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

a response sending unit that sends, 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.

7. A portable terminal comprising:

a semiconductor integrated circuit device for use in a data communication apparatus, the semiconductor integrated circuit device including

a setting unit that sets, 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

a response sending unit that sends, 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.
