Abstract

A mechanism is provided for sensor sharing control dynamically. One or more sensor use permissions are received from one or more sensor provider terminals. For each sensor use permission, a sensor use permission is recorded in an authorization policy thereby forming a set of authorization policies. A use request is recorded for sensor use request information received from a sensor user terminal in a request policy. A search is performed for any authorization policy in the set of authorization policies that matches the request policy. Responsive to identifying the authorization policy that matches the request policy, a list of sensors included in the sensor use permissions of an authorization policy that matches the request policy is created. The list of sensors is transmitted to the sensor user terminal, where the search is performed again dynamically when the request policy or one of the set of authorization policies is changed.

Claims

1. A sensor sharing control apparatus comprising:

a processor; and

a memory coupled to the processor, wherein the memory comprises instructions which, when executed by the processor, cause the processor to;

receive one or more sensor use permissions from one or more sensor provider terminals;

for each sensor use permission, record a sensor use permission in an authorization policy thereby forming a set of authorization policies;

receive sensor use request information from a sensor user terminal;

record a use request for the sensor use request information in a request policy, the request policy including one or more minimum requirements of a sensor requested by a user of the sensor user terminal, wherein the one or more minimum requirements includes at least one requirement other than sensor location;

responsive to the request policy being recorded, search for any authorization policy in the set of authorization policies that matches the request policy;

responsive to identifying the authorization policy that matches the request policy, creating a list of sensors included in the sensor use permissions of the authorization policy that matches the request policy; and

transmitting the list of sensors to the sensor user terminal, wherein the search is performed again dynamically when the request policy or one of the set of authorization policies is changed;

wherein the instructions further cause the processor to;

receive a list of available sensors;

create a token allowing the sensor user terminal to control a sensor in the list of available sensors; and

transmit the token to the sensor user terminal.

2. The sensor sharing control apparatus according to claim 1, wherein the instructions further cause the processor to:

authenticate the validity of a sensor user associated with the sensor user terminal in accordance with the sensor use request information, wherein the sensor use request information is recorded in the request policy when the authentication is successful.

3. The sensor sharing control apparatus according to claim 1, wherein the instructions further cause the processor to:

authenticate the validity of a sensor provider associated with the sensor use terminal in accordance with each sensor use permission, wherein the sensor use permission is recorded in the authorization policy when the authentication is successful.

4. The sensor sharing control apparatus according to claim 1, wherein the instructions further cause the processor to:

manage statuses of respective sensors; and

create a list of available sensors based on the status of the respective sensors.

5. The sensor sharing control apparatus according to claim 1, wherein receiving the sensor use request information includes receiving positional information of the sensor user terminal at regular intervals and updating the associated request policy.

6. The sensor sharing control apparatus according to claim 4, wherein the instructions further cause the processor to:

obtain positional information of a sensor in the list of available sensors at regular intervals and update the associated authorization policy.

7. The sensor sharing control apparatus according to claim 1, wherein the sensor use request information includes a user terminal ID, a sensor type, a position, and a degree of secrecy.

8. The sensor sharing control apparatus according to claim 1, wherein the sensor use permission includes a sensor type, an installation location, a sensor serial number, and a degree of secrecy.

9. The sensor sharing control apparatus according to claim 1, wherein responsive to receiving the list of sensors, the sensor user terminal is configured to:

display a map on a display device based on positional information of the sensor user terminal and each sensor in the list of sensors;

in response to designation of a sensor searching range on the displayed map, display the controllable sensors located within the range, as objects, at the positions of the corresponding sensors;

in response to selection of the object, display information of the corresponding sensor; and

in response to designation of a control of the sensor, transmit a signal for controlling the sensor.

10. The sensor sharing control apparatus according to claim 9, wherein, responsive to receiving the signal for controlling the sensor making a function included in the sensor controllable;

receiving a token from a sensor user terminal; and

enabling the function to be controlled from the sensor user terminal when the received token matches the stored token.

11. The sensor sharing control apparatus according to claim 9, wherein:

the sensors are dynamically updated when the sensor searching range is changed or moved, and the updated sensors are displayed as objects, and

a moving object is set at a center of the sensor searching range and the position of the moving object is acquired based on information from the sensors and the sensor searching range is dynamically changed in accordance with the movement of the moving object.

12. A method, in a data processing system, for performing sensor sharing control dynamically, the method comprising:

receiving one or more sensor use permissions from one or more sensor provider terminals;

for each sensor use permission, recording a sensor use permission in an authorization policy thereby forming a set of authorization policies;

receiving sensor use request information from a sensor user terminal;

recording a use request for the sensor use request information in a request policy, the request policy including one or more minimum requirements of a sensor requested by a user of the sensor user terminal, wherein the one or more minimum requirements includes at least one requirement other than sensor location;

responsive to the request policy being recorded, searching for any authorization policy in the set of authorization policies that matches the request policy;

responsive to identifying the authorization policy that matches the request policy, creating a list of sensors included in the sensor use permissions of the authorization policy that matches the request policy; and

transmitting the list of sensors to the sensor user terminal, wherein the search is performed again dynamically when the request policy or one of the set of authorization policies is changed;

the method further comprising;

receiving a list of available sensors;
