Abstract

A management system of a multimedia comprises a multimedia apparatus and a multimedia controller for managing and controlling the multimedia apparatus. The management system has processing means for transmitting and receiving a message between the multimedia controller and the multimedia apparatus, for automatically setting a predetermined name with respect to an owner of the multimedia apparatus, and for automatically or manually setting predetermined attributes with respect to attributes. The presence or absence of the right to access to the multimedia apparatus is judged in accordance with the contents of the attributes. By setting the multimedia apparatus itself to an object, a multimedia apparatus object is constructed in the multimedia apparatus. A circuit to manage a self secret protection is provided in the multimedia apparatus object. By setting a file in the multimedia apparatus to an object, attributes and an owner of the file are concealed in the file object, thereby protecting the secret of the file object.

Claims

1. An information management system comprising:

external memory means for storing various information including access information indicative of permission or inhibition of access to said external memory means;

input means for inputting an instruction for performing an access to said external memory means;

information memory means for storing the access information transferred from said external memory means; and

control means for controlling the access in response to the instruction input by said input means on the basis of the access information stored in said information memory means.

2. A system according to claim 1, wherein the access information includes an owner, a group, and other items.

3. A system according to claim 2, wherein the access information is classified depending on a kind of access.

4. A system according to claim 2, wherein the owner, group, and others items are discriminated by a user ID.

5. A system according to claim 1, wherein said external memory means comprises a video tape recorder.

6. A system according to claim 1, wherein said external memory means comprises a digital compact cassette.

7. An information management method comprising the steps of:

storing access information indicative of permission or inhibition of access to external memory means, the access information being transferred from the external memory means;

inputting an instruction for performing an access to the external memory means; and

controlling the access in response to the input instruction on the basis of the stored access information.

8. An information processing apparatus comprising:

memory means for storing access information indicative of permission or inhibition of access to external memory means, the access information being transferred from the external memory means;

receiving means for receiving an instruction for performing an access to the external memory means; and

control means for controlling the access in response to the instruction received by said receiving means on the basis of the access information stored in said memory means.

9. An apparatus according to claim 8, wherein the access information includes an owner, a group, and other items.

10. An apparatus according to claim 9, wherein the access information is classified depending on a kind of access.

11. An apparatus according to claim 9, wherein the owner, the group, and the other items are discriminated by a user ID.

12. An apparatus according to claim 8, wherein the external memory means comprises a video tape recorder.

13. An apparatus according to claim 8, wherein the external memory means comprises a digital compact cassette.

14. An information processing method comprising the steps of:

storing access information indicative of permission or inhibition of access to external memory means, the access information being transferred from the external memory means;

receiving an instruction for performing an access to the external memory means; and

controlling the access in response to the received instruction on the basis of the stored access information.

15. A method according to claim 14, wherein the access information includes an owner, a group, and other times.

16. A method according to claim 15, wherein the access information is classified depending on a kind of access.

17. A method according to claim 15, wherein the owner, the group, and the other items are discriminated by a user ID.

18. A method according to claim 14, wherein the external memory means comprises a video tape recorder.

19. A method according to claim 14, wherein the external memory means comprises a digital compact cassette.

20. An information processing apparatus comprising:

memory means for storing access information indicative of permission or inhibition of access to a file, the access information being transferred from the file;

receiving means for receiving an instruction for performing an access to the file; and

control means for controlling the access in response to the instruction received by said receiving means on the basis of the access information stored in said memory means.

21. An apparatus according to claim 20, wherein the access information includes an owner, a group, and other items.

22. An apparatus according to claim 21, wherein the access information is classified depending on a kind of access.

23. An apparatus according to claim 21, wherein the owner, the group, and the other items are discriminated by a user ID.

24. An information processing method comprising the steps of:

storing access information indicative of permission or inhibition of access to a file, the access information being transferred from the file;

receiving an instruction for performing an access of the file; and

controlling the access in response to the received instruction on the basis of the stored access information.

25. A method according to claim 24, wherein the access information includes an owner, a group, and other items.

26. A method according to claim 25, wherein the access information is classified depending on a kind of access.

27. A method according to claim 25, wherein the owner, the group, and the other items are discriminated by a user ID.
