Access control system and access control method using the same

Abstract

Disclosed herein are an access control system and an access control method using the same. The access control method in which a door operating device determines whether to open a door on the basis of an authentication token acquired from a user terminal without intervention of an authentication server includes obtaining the authentication token from the user terminal; determining whether the user have authorization for accessing the door based on a authentication information included in the authentication token; controlling the door to be opened in case of determined that the user have authorization for accessing the door.

What is claimed is: 
     
         1 . An access control method for determining whether to open a target door on the basis of an authentication information included in an authentication token and an access status information, the access control method comprising:
 obtaining the authentication token from a user terminal through a first communication unit;   determining whether to open the target door on the basis of the authentication information included in the authentication token and the access status information; and   controlling the target door to be opened in case of determination that the target door to be opened.   
     
     
         2 . The access control method  claim 1 , wherein the determining whether to open the target door comprising:
 determining that the target door should be open when the user has an authority for accessing the target door as a result of checking the authentication information and a access status for target door is valid as a result of checking the access status information.   
     
     
         3 . The access control method  claim 2 , wherein the determining whether to open the target door comprising:
 determining that the target door should be open when the access status is related to the first communication unit.   
     
     
         4 . The access control method of  claim 2 ,
 wherein the authentication information includes identification information of a door operating device corresponding to the target door, to which authority is assigned, and   wherein the determining whether to open the target door comprises determining that the user has the authority to access the door when identification information of at least one of the door operating device and the target door is included in the authentication information.   
     
     
         5 . The access control method of  claim 2 ,
 wherein the authentication information includes at least one of the identification information of the door operating device and the identification information of the door, which are stored in the authentication server, and includes an authority value corresponding to the identification information, and   wherein the determining whether to open the target door comprises determining that the user has the authority to access the door when the authentication information includes identification information of at least one of the door operating device and the door, and when the authority value corresponding to the identification information is a predetermined value indicating that there is authority.   
     
     
         6 . The access control method of  claim 1 , further comprising:
 obtaining the updated access status information that is changed from a first status to a second status in case of determination that the target door to be opened.   
     
     
         7 . The access control method of  claim 6 , further comprising:
 transmitting the updated access status information to the user terminal through a second communication unit.   
     
     
         8 . The access control method of  claim 7 ,
 wherein the first communication is located outside of the target door, and   wherein the second communication is located inside of the target door.   
     
     
         9 . An access control method comprising:
 obtaining an authentication token from a user terminal by a first door operating device;   determining whether to open the first door on the basis of the authentication information included in the authentication token and an access status information for the first door by the first door operating device;   controlling the first door to be opened in case of determination that the first door to be opened by the first door operating device;   obtaining the authentication token from the user terminal by a second door operating device;   determining whether to open the second door on the basis of the authentication information included in the authentication token, an access status information for the first door and an access status information for the second door by the second door operating device; and   controlling the second door to be opened in case of determination that the second door to be opened by the second door operating device.   
     
     
         10 . The access control method  claim 9 , wherein the determining whether to open the second door comprising:
 determining that the second door should be open when the user has an authority for accessing the second door as a result of checking the authentication information, an access status in the access status information for the first door is a second status, and the access status in the access status information for the second door is a first status.   
     
     
         11 . A non-transitory recording medium having a program recorded thereon for executing the method of any one of  claims 1  and  10 . 
     
     
         12 . A door operating device comprising:
 a first communication unit configured to obtain an authentication token from a user terminal;   a door driving unit configured to provide power necessary to open a target door; and   a door control unit configured to determine whether to open the target door on the basis of the authentication information included in the authentication token and an access status information, and control the target door to be opened in case of determination that the target door to be opened.   
     
     
         13 . The door operating device of  claim 12 ,
 the door control unit configured to obtain the updated access status information that is changed from a first status to a second status in case of determination that the target door to be opened.   
     
     
         14 . The door operating device of  claim 13 ,
 wherein the door operating device further comprises a second communication unit, and   the door control unit configured to transmit the updated access status information to the user terminal through the second communication unit.
