It is made possible to maintain the security of one electronic device to which a plurality of other electronic devices are capable of being connected. To accomplish this, a notebook-type personal computer has an internal ROM storing ID information specific to this personal computer. The notebook-type personal computer is folded up and inserted into a docking station through an insertion port so as to be electrically connected to the docking station and rendered capable of executing processing that utilizes the resources of the docking station. The docking station has an internal non-volatile memory storing the IDs of notebook-type personal computers that are allowed to use the docking station. When a notebook-type personal computer is inserted into and connected with the docking station, use of the docking station is not allowed if the ID of this notebook-type personal computer has not been stored in the docking station. |

DETAILED DESCRIPTION Accordingly, an object of the present invention is to provide an information processing system, as well as a control method, in which it is possible to maintain the security of one electronic device to which a plurality of other electronic devices are capable of being connected.
According to the present invention, the foregoing object is attained by providing an information processing system constituted by a first electronic device having a standard input/output unit and being capable of executing processing independently, and a second electronic device having a standard input/output unit which, when the first electronic device has been connected to the second electronic device, takes the place of the standard input/output unit of the first electronic device, wherein the first electronic device comprises memory means storing ID information specific to the first electronic device, detecting means for detecting whether the first electronic device has been connected to the second electronic device, judging means for determining, on the basis of the ID information stored in the memory means, whether the first electronic device has been given permission to use the second electronic device if the detecting means detects that the first electronic device has been connected to the second electronic device, and control means for establishing an operating state by using the second electronic device if permission has been given to use the second electronic device, wherein the second electronic device has second memory means storing the ID information of the first electronic device to which permission has been given.
In a preferred embodiment, the second electronic device further includes third memory means for storing a password, and the first electronic device has second judging means which, when a character string is entered using the standard input/output unit of the second electronic device in a case where the first judging means has determined that the permission to use the second electronic device has not been given, compares the entered character string with the password and determines whether the character string and password match, and registration means for registering the ID information of the first electronic device in the second memory means of the second electronic device if matching is determined by the second judging means
