That is, the management web page can provide the manager with a function to directly select any one employee included in the list among internal employees to send a message, and the access right required for facial recognition technology among internal employees is not granted. You can provide a function that selects all employees who have not been granted and sends a message, and provides a function that selects all employees who have passed a certain period of time after being granted access rights among internal employees and sends a message. can provide

By such an input of the manager, an internal employee who has received a message transmitted from the message transmitting unit 112 to his/her user terminal 200 can access the registration web page through the address included in the message, , as shown in FIGS. 4A to 4E , it is possible to perform a registration procedure of uploading a face photo after self-authentication according to the guidance.

The face picture of the internal employee uploaded through this process must be a picture taken in real time through the shooting function by the camera 120 of the user terminal 200, and the upload of the picture stored in the user terminal 200 is It is limited to problems such as changes in faces over time or theft of other people's photos.

Thereafter, the extraction unit 113 extracts one face image by identifying the face of the internal employee from the photo uploaded from the user terminal 200 accessing the registration web page, and the registration unit 115 is the extraction unit The face image extracted in step 113 is registered to grant regular access rights. can be displayed.

At this time, the photo uploaded from the user terminal 200 should be a single photo in which the entire front of the face is clearly shown by taking a close-up shot of the face of the internal employee, but the uploaded photo may have various problems, and the problem is that of the internal employee In the case of face identification, the extraction of the face image by the extraction unit 113 is impossible, so the registration cannot be completed.

Therefore, when an error occurs in the identification of the user's face or the extraction of one face image by the extraction unit 113, the signal transmitter 114 sends a request signal for requesting the user to re-upload the photo to the web server ( 100), it is possible to display a request message requesting re-upload of the photo on the screen of the user terminal 200 in a state in which the registration web page is accessed.

In addition, the administrator can input the phone number of a visitor who needs free entry in a building, etc. into the system without a separate identification process, and the visitor whose phone number has been entered is sent to the message sent to the user terminal 200 in his or her name. Preparation for use of the present invention can be completed by performing a registration procedure for one's face according to the included guidance.

In this case, the term “visitor” in the present invention includes both a visitor who has directly visited a security facility, company, school, etc., where the present invention is used, and a prospective visitor who has notified the date and time of the visit in advance.

Specifically, the present invention may be configured to store visitor's personal information including a phone number in the database 111 for a certain period of time, and to automatically delete the visitor's personal information after a certain period of time has elapsed, and the register ( 115) registers the face image extracted by the registration procedure by the message transmitting unit 112, the extracting unit 113 and the signal transmitting unit 114 based on the visitor's personal information to obtain the date and time. It may be configured to grant temporary access rights that must be included and additionally limit the location.

The visitor's personal information input at this time is information directly provided by each visitor to the manager or information provided to the manager collectively by the group to which a large number of visitors belong, and it is assumed that it is not false. not included in the invention.

Therefore, an administrator using the present invention can access and log in to the management web page using the administrator terminal 300, and input visitor's personal information including a phone number according to the form provided by the management web page, , the input visitor personal information is stored in the database 111 .

That is, the management web page may provide an administrator with a function to directly select any one visitor included in the visitor list or to transmit a message by collectively selecting all visitors to which access rights are not granted.

Thereafter, the visitor who receives the message transmitted from the message transmitting unit 112 to their user terminal 200 can access the registration web page through the address included in the message, as shown in FIGS. 4A to 4E . As described above, you can perform a registration procedure to upload your own face photo after authenticating yourself according to the guide.

Thereafter, the extraction unit 113 extracts one face image by identifying the visitor's face from the photo uploaded from the user terminal 200 accessing the registration web page, and the registration unit 115 extracts an extraction unit ( 113) registers the extracted face image to grant access, and when access is granted, a message notifying completion of registration may be displayed on the screen of the user terminal 200 in a state in which the registration web page is accessed. there is.

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

However, while the access rights granted to internal employees by the registration procedure targeting internal employees are regular access rights without restrictions on period, access time, etc., access rights granted to visitors by the registration procedure targeting visitors There is a difference in the temporary access right that may have restrictions including the date and time, and additional restrictions may occur in the accessible places, etc., and such restrictions are caused by input by the administrator.

That is, in the management web page, when the administrator inputs a message requesting execution of the registration procedure to be transmitted to the visitor's user terminal 200, restrictions such as date and time are inputted together, so that the access permission granted to the visitor The registration unit 115 performs a registration procedure 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 to grant temporary access rights that must include the date and time and additionally limit the location.

In this case, the administrator can access the web page for management even after temporary access is granted to the visitor, and can arbitrarily change the conditions of the already granted restrictions, and can lose the temporary access right, but completely remove all restrictions granted to the visitor. It is restricted so that it cannot be released.

In addition, the management server 110 may transmit a message informing the visitor of this fact to the user terminal 200 of the visitor when the loss of the temporary access right granted to the visitor is imminent. Through the link address, it is possible to request extension of temporary access rights with imminent loss.

The request for extension of the temporary access right is configured to be extended a specified number of times for a specified time by setting 6:00 pm, which is widely used as a normal leave time, as a deadline.

In response to this, as an embodiment of the present invention, a visitor whose temporary access right is imminent, whose deadline is set until 4 pm, may extend 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 who is about to lose the temporary access right, whose deadline is set until 6 pm, is configured so that the link address requesting the extension of the temporary access right is not included. Therefore, it is not always possible to extend the temporary access right.

In addition, the present invention provides access to other internal employees who have been granted access rights for the purpose of verifying the authenticity of the facial photos uploaded by the internal employees or verifying the authenticity of the facial photos that are the basis of the access permission granted to the internal employees. It may be configured to request confirmation of a face photograph of a particular 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 extraction unit 113 to the web server 100, and a confirmation web page for confirmation. to be registered in , and the message transmission unit 112 transmits a message including an address linked to the web page for confirmation to a plurality of user terminals 200 by using the phone number included in the employee's personal information. can be configured.

At this time, the registration unit 115 is an internal employee identified only when the confirmation of the face photo or face image occurs from the user terminals 200 of a certain percentage or more among the plurality of user terminals 200 accessing the confirmation web page. may be configured to grant access rights to

At this time, it is desirable that the majority of internal employees who are requested to confirm the face photo of a specific internal employee consist of internal employees who work in the same department as the specific internal employee, but new employees who are difficult to confirm by other internal employees In the case of an employee, the above confirmation procedure may be omitted.

With such a configuration, the present invention has an effect that can prevent an internal employee from receiving a regular access right by photographing another person's face in advance may cause verification by other internal staff to occur, allowing for granted regular access privileges to be maintained or lost.

On the other hand, the camera 120 is a known photographing device that generates image information by photographing a passer-by, and is installed so as to photograph the face of the front side of a passer who approaches the opening/closing device installed to control access.

In addition, the recognition device 130 recognizes the face of the passer-by shown in the image information, compares the recognized face with the face image included in the access right, confirms the passer's access right, and determines whether or not the access right is checked. As an information processing device that determines passage permission according to

Therefore, when an internal employee who is granted regular access or a visitor who has been granted temporary access through the registration procedure as described above approaches the opening/closing device installed to control access, shooting by the camera 120 and the recognition The opening and closing device may be automatically opened according to the confirmation by the device 130 , and restrictions on passers-by for which the registration procedure has not been performed may be limited.

In addition, the camera 120 and the recognition device 130 may be installed at the exit of a place requiring access management, and the management server 110 is generated from the recognition device 130 installed at the entrance and the exit, respectively. A pass permit for an employee can be used to manage the time and attendance of that internal employee.

In addition, the management server 110 is based on the pass permission for the visitor generated by the recognition device 130 installed at the entrance and the exit, respectively, to discover the visitor remaining inside the building at the point in time the temporary access right is lost. In case a remaining visitor is found, it is possible to re-notify the fact that the temporary access right is lost to the visitor's user terminal 200 and transmit a message urging them to leave the building at the same time, and to the manager terminal 300 Visitors who remain inside the building can be notified that they have been found.
