Abstract

Provided are apparatuses, systems and methods for providing security services. The apparatus includes a network interface unit for transceiving data between a control device and a management device, a controller for controlling provision of services requested from the control device through the network interface unit when a permit time, during which a target of security service is allowed to be given services, is longer than a used time, during which predetermined services are provided to the target of security service, and a used time processing unit for updating the used time by reflecting time during which the services are provided. When security services are performed, services of a controlled device can be provided during the permitted time according to a user or a control device.

requesting by the controlled device, the management device to update the used time period stored in the management by reflecting the time during which the security services requested by the control device are provided;

updating by the management device, the used time period ;

stored in the management device by reflecting the time during which the security services requested by the control device are provided, and

updating, by the controlled device, the used time period stored in the controlled device by reflecting the time during which the security services requested by the control device are provided,

wherein the permit time period is a total amount of time during which the target of the security services is allowed to be provided with the security services, and

wherein the target of the security services has its own used time period.

7. The method of claim 6, wherein the target of the security services refers to any one among the control device, a user who requests security services via the control device, and a user group to which the user belongs.

8. The method of claim 6, wherein the controlled device periodically performs updating of the used time period.

9. The method of claim 6, further comprising:

searching, by the management device that received the request, the permit time period and the used time period of the target of the security services;

transmitting, by the management device, the permit time period and the used time period to the controlled device; and

comparing, by the controlled device, the received permit time period with the used time period.

10. The method of claim 8, further comprising, by the controlled device, stopping provision of the security services if the permit time period is not longer than the updated used time period.

11. The method of claim 9, wherein the used time period is a total amount of time during which the security services have been previously provided to the target of the security services through a plurality of controlled devices constituting a home network, and the permit time period is a total amount of time during which the target of the security services is allowed to be provided with the security services through the plurality of controlled devices constituting the home network.
