In addition, when an error occurs in the identification of the user's face or the extraction of one face image by the extraction unit 113, a procedure such as transmission of a request signal by the signal transmission unit 114 is performed to obtain a face picture of an internal employee. The procedure for registration is the same as in the case of registration.

However, while the access rights granted to internal employees through the registration process for internal employees are regular access rights without restrictions on period and access hours, the access rights granted to visitors through the registration process for visitors The difference occurs in that is a temporary access right that is subject to restrictions including the date and time, and additional restrictions may occur such as places where access is possible, and such restrictions are caused by input by the administrator.

That is, when the administrator inputs a message requesting the execution of the registration procedure to the visitor's user terminal 200, the management webpage requires the administrator to input restrictions such as date and time, so that the access authority granted to the visitor must occur, and the registration unit 115 is registered by the message transmission unit 112, the extraction unit 113, and the signal transmission unit 114 based on the visitor's personal information. It is characterized in that it is configured to register the extracted face image, necessarily include the date and time, and grant temporary access rights that can additionally limit the location.

At this time, even after the temporary access right is granted to the visitor, the administrator accesses the web page for management and can arbitrarily change the condition of the previously granted restriction or lose the temporary access right, but completely remove all restrictions granted to the visitor. It is restricted so that it cannot be unlocked.

In addition, the management server 110 may transmit a message notifying the visitor of this fact to the user terminal 200 of the visitor when the point of loss of the temporary access right granted to the visitor is imminent, and the visitor may receive information included in the message. Through the link address, you can request an extension of temporary access rights that are about to be lost.

Such a request for extension of the temporary access right is configured to be extended for a specified number of times by a specified time, with 6:00 p.m., which is widely used as a normal work-off time, as a deadline.

In response to this, as an embodiment of the present invention, a visitor imminently losing the temporary access right for which the deadline is set until 4:00 pm is extended by 10 minutes through the link address included in the message notifying the imminent loss of the temporary access right. You can apply up to 3 times.

However, the message sent to the visitor imminently losing the temporary access right with a deadline set at 6:00 PM is structured so that the link address requesting an extension of the temporary access right is not included, and both the above time and frequency can be changed according to the circumstances. Therefore, it is not necessarily possible to extend temporary access rights.

In addition, the present invention provides other internal employees with access rights for the purpose of verifying the authenticity of the face photo uploaded by the internal employee or the authenticity of the face photo that is the basis of the access permission granted to the internal employee. It may be configured to request verification of a face picture of a specific internal employee and receive a response thereto.

In order to realize such a configuration, the management server 110 transmits a face photo uploaded by an internal employee or a face image extracted from the extractor 113 to the web server 100 to confirm a web page for confirmation. and the message transmission unit 112 transmits a message including an address linked to the confirmation web page to a plurality of user terminals 200 using the phone number included in the employee personal information. can be configured.

At this time, the registration unit 115 checks the face photo or face image from the user terminals 200 of a certain ratio or more among the plurality of user terminals 200 accessing the web page for confirmation, and only when the confirmation of the face photo or face image occurs, the confirmed internal employee It can be configured to grant access rights to.

At this time, it is desirable that most of the internal employees who are requested to check the face photo of the specific internal employee are composed of internal employees working in the same department as the specific internal employee, but it is difficult for other internal employees to check the face photo. In the case of an employee or the like, the above confirmation procedure may be omitted.

With this configuration, the present invention has an effect of preventing an internal employee from taking a picture of another person's face and being granted regular access rights in advance, and even in the case of a new employee, when a certain time elapses may cause verification by other internal personnel to occur, resulting in the maintenance or loss of regular access privileges granted.

On the other hand, the camera 120 is a known photographing device that generates image information by photographing a passer-by, and is installed to capture a frontal face of a passer-by approaching an opening/closing device installed to control entry and exit.

In addition, the recognizing device 130 recognizes the face of the passer shown in the image information, compares the recognized face with a face image included in the access right, checks the passer's access right, and determines whether or not the access right has been confirmed. It is an information processing device that determines passage permission according to the information processing device, and has the control authority of the switchgear installed to control access.

Therefore, when an internal employee with regular access authority or a visitor with temporary access authority accesses the opening/closing device installed to control access through the above registration procedure, the photographing by the camera 120 and the recognition According to confirmation by the device 130, the opening/closing device may be automatically opened, and restrictions on passersby who have not undergone the registration procedure may be restricted.

In addition, the camera 120 and the recognition device 130 may be installed at the exit of a place where access management is required, and the management server 110 generates internal information generated by the recognition device 130 installed at the entrance and exit, respectively. Passage for employees can be used to manage the time and attendance of its internal employees.

In addition, the management server 110 can detect visitors remaining inside the building at the time the temporary access right is lost based on the pass permission for the visitor generated by the recognition device 130 installed at the entrance and exit, respectively. If a remaining visitor is found, the fact that the temporary access right has been lost may be re-notified to the user terminal 200 of the visitor and a message urging him to leave the building may be transmitted, and the manager terminal 300 may Visitors remaining inside the building may be notified of their discovery.
