Description

Non-face-to-face dual security access control system}

The present invention relates to a non-face-to-face dual security access control system, and more specifically, to a non-face-to-face dual security access control system for controlling building access using facial recognition and beacon-based visitor recognition.

The existing corporate access control method involves visitors meeting with a receptionist at the entrance of the building, writing down the purpose of the visit, their name, the department they are visiting, and the name of the person in charge, and leaving their ID card.

However, in situations where face-to-face contact is difficult due to highly contagious infectious diseases such as COVID-19, or for companies that find it difficult to hire separate information staff, a system that allows for convenient and safe access control in a non-face-to-face manner is needed.

Meanwhile, as vaccinations expand, the prevailing view in major countries is that even if they return to their daily lives away from home-based life and work, the cycle of easing and strengthening lockdowns will continue to repeat due to the spread of various infectious diseases in the future.

In addition, the general open work space was operated non-face-to-face without an information desk, allowing an unspecified number of people to come and go, but there were restrictions such as access times, so outside of working hours, only people who had been issued a security card in advance were allowed to enter.

Therefore, there is a need for a non-face-to-face double security kiosk that can open the door by authenticating that the pass issued non-face-to-face and the person holding it are the same person.

Afterwards, the face is detected through the customer pass check unit 230, and then it is checked whether the customer has a pass.

If you do not possess a beacon-type customer pass, it will not be recognized, so procedures to issue a beacon-type customer pass will be performed on site.

Afterwards, the face registration unit 240 checks whether the customer passes the pass and, when possessed, matches the face information with the corresponding customer information stored in the visitor information database 130 based on the detected face area, stores and processes the facial information. will be.

In other words, face registration procedure processing is performed and the corresponding face information is stored and processed.

Afterwards, face recognition of the customer wishing to enter is performed through the face recognition unit 250.

It is a self-evident fact that the operation of the face recognition unit can be recognized in real time at the relevant location after detecting the face, but it can also be recognized when the face is visited again at a later date.

And, it is a self-evident fact that in case face recognition fails, a face registration procedure can be performed to re-register the face.

Thereafter, the access permission processing unit 260 outputs access permission information when the face recognition result matches the registered customer's face.

Meanwhile, according to a preferred embodiment, the face registration unit 240,

In other words, by improving face recognition performance using face recognition and beacon-based visitor recognition, user inconvenience caused by misrecognition of the conventional face recognition alone method is resolved, and access control for visitors is facilitated through issuance of beacon passes. It provides one advantage.

In addition, by providing an artificial intelligence-based non-face-to-face kiosk access control service, Bluetooth beacon passes are issued to new visitors through the access management platform, and separate guide personnel are deployed by allowing entry through a double security method through the facial recognition function. Since it can be operated without any equipment, management costs can be reduced and work efficiency can be promoted.

In addition, initial visitors must access and register on the access management platform, and the pass is issued in a form that is valid only for a certain period of time after consenting to personal information and undergoing an authentication process via smartphone.

In addition, the pass is part of the means of authenticating one's identity, and provides a security procedure for final determination through face recognition. (Face Verification)

In addition, the current face recognition rate shows an accuracy of 99.63% in the LFW (Labeled Faces in the Wild) dataset for FaceNet for a given image, but in reality, it falls below 75% in various environments such as lighting changes, and the present invention As shown, the use of FaceQnet, an artificial intelligence model, in the face registration process provides the effect of further strengthening access security by increasing the face recognition rate.

In addition, by predicting whether the images captured when registering a face using FaceQnet are suitable for face recognition purposes, selecting the most suitable photo, and then using the face embedding vector of this photo, it provides the effect of increasing the face recognition rate in the real environment. I do it.
