Abstract

An information processing device to solve the above-mentioned disadvantage according to the present invention comprises: information receipt part to receive a digital information from an external information record medium; first judgment part to judge whether the external information record medium is a medium which is readable and writable; second judgment part which judges whether a predetermined security processing is performed to the digital information to be received; and control part to control the information receipt part to refuse a receipt of the digital information which is judged that the medium is readable and writable by the first judgment part and a security processing is not performed by the second judgment part.

Claims

1. An information processing device comprising:

information receipt means to receive digital information from an external information storage medium;

first judgment means to judge whether said external information storage medium is a medium which is readable and writable;

second judgment means which judges whether a predetermined security processing is performed to the digital information to be received;

control means to control said information receipt means to refuse a receipt of the digital information when said external information storage medium is judged by said first judgment means as readable and writable and by said second judgment means to determine that the security processing is not performed; and

connector means for connecting a removable storage medium which is readable and writable, wherein

as to digital information for which it is judged by said second judgment means that encoding processing is performed, said control means decodes the encoded information, and

as to digital information which is read from said external information medium for which it is judged by said first judgment means that said external information medium is not readable and writable and for which it is judged by said second judgment means that encoding processing is not performed, said control means encodes the digital information and prompts the information processing device to write the encoded digital information on said removable medium via said connector means.

2. The information processing device according to claim 1, wherein said security processing is a processing which reversibly transforms a pattern of the digital information according to a predetermined rule.

3. The information processing device according to claim 1, wherein said digital information is a digital information with an execution format to activate a device.

4. The information processing device according to claim 3, wherein a holding area of the digital information with said execution format is held in a volatile memory.

5. An information processing device comprising:

information receipt means to receive a digital information from an external information storage medium;

first judgment means to judge whether said external information storage medium is a medium which is distributed under a specific condition;

second judgment means which judges whether a predetermined security processing is performed to the digital information to be received;

control means to control said information receipt means to refuse a receipt of the digital information which is judged that the medium is not distributed under the specific condition by said first judgment means and a security processing is not performed by said second judgment means; and

connector means for connecting a removable storage medium which is readable and writable, wherein

as to digital information for which it is judged by said second judgment means that the predetermined security processing is performed, said control allows the receipt of the digital information, and

as to digital information which is read from said external information medium for which it is judged by said first judgment means that said external information medium is distributed under the specific condition and for which it is judged by said second judgment means that the predetermined security processing is not performed, said control means encodes the digital information and prompts the information processing device to write the encoded digital information on said removable medium via said connector means.

6. The information processing device according to claim 5, wherein said security processing is a processing which reversibly transforms a pattern of the digital information according to a predetermined rule.

7. The information processing device according to claim 5, wherein said digital information is a digital information with an execution format to activate a device.

8. The information processing device according to claim 7, wherein a holding area of the digital information with said execution format is held in a volatile memory.

9. An information processing device comprising:

information transmission/receipt means to transmit/receive a digital information to/from an external information storage medium;

first judgment means to judge whether said external information storage medium is a medium which is readable and writable or a medium which is distributed under a specific condition;

second judgment means which judges whether a predetermined security processing is performed to the digital information to be received; and

control means to control said information receipt means to refuse a receipt of the digital information when said external information storage medium is judged by said first judgment means as readable and writable or as being distributed under the specific condition by said first judgment means, and by said second judgment means to determine that the security processing is not performed and to prompt writing the digital information, to which a security processing is performed, on said external information storage medium; and

connector means for connecting a removable storage medium which is readable and writable, wherein

as to digital information for which it is judged by said second judgment means that security processing is performed, said control means decodes the encoded information, and

as to digital information which is read from said external information medium for which it is judged by said first judgment means that said external information medium is not readable and writable or as being distributed under the specific condition, and for which it is judged by said second judgment means that security processing is not performed, said control means encodes the digital information and prompts the information processing device to write the encoded digital information on said removable medium via said connector means.

10. The information processing device according to claim 9, wherein said security processing is a processing which reversibly transforms a pattern of the digital information according to a predetermined rule.

11. The information processing device according to claim 9, wherein said digital information is digital information with an execution format to activate a device.

12. The information processing device according to claim 11, wherein a holding area of the digital information with said execution format is held in a volatile memory.

13. A computer readable storage medium comprising a program providing functionality to perform the steps of:

(1) judging whether an external information storage medium is a medium which is readable and writable;

(2) judging whether a predetermined security processing is performed to a digital information to be received; and

(3) controlling a mechanism for receiving digital information to refuse a receipt of the digital information which is judged that the medium is readable and writable and is judged that the security processing is not performed,

on a computer which comprises said mechanism to receive the digital information from said external information storage medium;

further comprising the steps of;

(4) connecting a removable storage medium which is readable and writable via a connecting means;

(5) for digital information for which it is judged that security processing is performed, decoding the encoded information; and

(6) for digital information for which it is judged that said external information storage medium is not readable and writable and for which it is judged that security processing is not performed, encoding and writing the encoded digital information on said removable medium via said connector means.

14. The storage medium according to claim 13, wherein said program performs all or a part of said functionality in cooperation with a control program which is installed in an information processing device comprising said computer and said storage medium.

15. A computer readable storage medium comprising a program providing functionality to perform the steps of:

(1) judging whether an external information storage medium is a medium which is readable and writable;
