At this time, the authentication means is a configuration for authenticating the user separately from the authentication by the authentication server, which will be described later. Specifically, the authentication means authenticates whether or not the user has a right to use the user terminal 100. The authentication means may use an authentication method using a password or a pattern input, and may use a biometric authentication method such as fingerprint or iris.

The field network system 200 authenticates the user terminal 100 connected through the external network and provides the CCTV image service to the authenticated user terminal. The field network system 200 includes an authentication server 210 for authenticating the user terminal 100 and a CCTV image web server 220 for providing a CCTV image service to the authenticated user terminal. Preferably, the field network system 200 may provide a CCTV image service to the user terminal 100 in the form of a web site. In this case, it is possible to provide a CCTV video service only by accessing the corresponding website without installing a separate application in the user terminal 100. [

In addition, the field network system 200 may include one or more CCTV systems 250 for providing CCTV images to the CCTV video web server 220. The field network system 200 shown in FIG. 1 is divided into functional units in order to perform the functions of the present invention. According to the embodiment, each of the components may be composed of integrated functional units, The unit may be configured in one or more separate functional units.

The authentication server 210 authenticates the user terminal 100 connected through the external network. Specifically, when the user terminal 100 accesses the field network system 200 and transmits login information, the authentication server 210 authenticates the user terminal 100 using the login information. The login information may include at least one of identification information of a user terminal, identification information of a user, and a password. The identification information of the user terminal is information uniquely assigned to the user terminal, for example, a telephone number, a product number, a MAC address of the user terminal, a unique number of the SIM card, and the like. The identification information of the user is information uniquely assigned to the user. For example, biometric information such as an ID, an employee number, a name, and a fingerprint may be used.

The authentication information and the user information may be periodically transmitted from the intra-company network system 300, which will be described later. At this time, the authentication information and the user information are preferably transmitted in an encrypted form. The authentication server 210 updates and stores the received authentication information and user information in a separate authentication database. Accordingly, when the authentication server 210 receives the login information transmission request and the connection request from the user terminal 100, the authentication server 210 can determine whether the user terminal is authenticated by comparing the authentication information stored in the authentication database. If the authentication is successful, the authentication server 210 allows the user terminal 100 to access the CCTV video web server 220, extracts user information about the user terminal, and provides the extracted user information to the CCTV video web server 220 . On the other hand, if the authentication fails, the authentication server 210 blocks the access of the user terminal 100 and transmits a message to the user terminal indicating that the authentication has failed.

Unlike the above embodiment, the authentication server 210 may authenticate the user terminal 100 in cooperation with the in-house network system 300 without storing authentication information and user information. In this case, when login information is transmitted from the user terminal 100 and an access request is received, the authentication server 210 transmits the authentication information received in the intra-company network system 300, and the intra-company network system 300 transmits the login information And transmits the authentication result to the authentication server. If the authentication of the user terminal 100 is successful, the authentication server 210 may allow the user terminal to access the CCTV image web server 220. In this case, the in-house network system 300 can transmit the user information about the user terminal 100 to the authentication server 210. On the other hand, if the authentication for the user terminal 100 fails, a message about the authentication failure is transmitted from the in-house network system 300 to the authentication server 210. The authentication server blocks the access of the user terminal, A failure message can be transmitted to the user terminal.
