Information processor
First Claim
1. An information processing apparatus connected to a bus via one of a plurality of control devices, which are connected to the bus, the apparatus comprising:
- storage means for storing authentication information of the control device for which control is allowed;
obtaining means for obtaining the authentication information of the control device which requests control via the bus;
comparing means for comparing the authentication information stored in the storage means and the authentication information obtained by the obtaining means; and
allowing means for allowing the control device which requests control to perform control based on the comparison result obtained from the comparing means.

Abstract
The present invention relates to an information processing apparatus in which a personal computer including a device can acquire access to the device on a network formed by IEEE 1394. When a personal computer 1-1 or a personal computer 1-2 requests acquirement of access from a hard disk drive (HDD) 11, the HDD 11 compares the global unique identifier (GUID) of the personal computer 1 and the GUID of the personal computer 1-1 stored in the HDD 11. If the GUIDs match, access is granted to the personal computer 1. That is, access is granted to only the personal computer 1-1. The present invention can be applied to HDDs.
