Control access to function of information device
First Claim
1. A control system for controlling access to a protected function of an information device, comprising:
- a communication device configured to communicate with the information device entering an area, the information device having a current information device identifier;
a database configured to store a relationship between the information device and a registered user;
a control computer communicably connected to the communication device, the control computer being configured to;
send to the information device, each time the information device exits the area, a next information device identifier that is different than the current information device identifier, the next information device identifier being for the information device to store, each time the information device exits the area, as an updated information device identifier in place of the current information device identifier;
identify the information device each time the information device enters the area based on receiving from the information device the updated information device identifier that was sent by the control computer to the information device a most recent time when the information device exited the area;
identify a user entering the area with the information device;
determine whether or not to permit access to the protected function based on the identified user and the registered user for the information device; and
control the information device via the communication device so as to unlock or lock the protected function based on a result of determination whether or not to permit access.

Abstract
A control system for controlling access to a protected function of an information device is disclosed. The control system includes a communication device configured to communicate with the information device entering an area. The control system also includes a database configured to store a relationship between the information device and a registered user. The control system further includes a control computer communicably coupled to the communication device. The control computer is configured to identify a user entering the area with the information device. The control computer is also configured to determine whether or not to permit access to the protected function based on the identified user and the registered user for the information device. The control computer is further configured to control the information device via the communication device so as to unlock or lock the protected function based on a result of determination whether or not to permit access.

13. A method for controlling, by a control computer, access to a protected function of an information device, where the information device has a current information device identifier, the method comprising:
-
sending to the information device, each time the information device exits an area, a next information device identifier that is different than the current information device identifier, the next information device identifier being for the information device to store, each time the information device exits the area, as an updated information device identifier in place of the current information device identifier; identify the information device each time the information device enters the area based on receiving from the information device the updated information device identifier that was sent by the control computer to the information device a most recent time when the information device exited the area; identifying a user entering an area with the information device; determining whether or not to permit access to the protected function based on the identified user and a registered user in relation to the identifier; and transmitting a control signal to the information device by the communication device so as to unlock or lock the protected function based on a result of determination whether or not to permit access.

14. An information device having a current information device identifier, comprising:
-
a communication device configured to communicate with a control computer in entering an area; a protected module, access to the protected module being controlled by the control computer; a lock control module configured to block access to the protected module if the protected module is locked; and an interface module for accessing the protected module via the lock control module; wherein the lock control module is further configured to; receive, from the control computer via the communication device each time the information device exits the area, a next information device identifier that is different than the current information device identifier, the next information device identifier being for the information device to store, each time the information device exits the area, as an updated information device identifier in place of the current information device identifier; send, to the control computer via the communication device for the control computer to use to identify the information device each time the information device enters the area, the updated information device identifier that was sent by the control computer to the information device a most recent time when the information device exited the area; receive a control signal from the control computer by the communication device; and unlock or lock the protected module in response to receiving the control signal. - View Dependent Claims (15)
