In one embodiment, in the visitor application page provided by the processor 106 to the visitor G1, the visitor G1 may be required to upload his selfie as the first face image GM1, and input related visit information (for example, the contact of the interviewee V1). Information (such as name, phone number, email address, affiliation, etc.), access time, number of visitors, etc.). In other embodiments, if multiple visitors want to visit the interviewee V1 at the same time, the processor 106 may request the visitor G1 to upload individual selfies of these visitors, or only include the group photos of the above-mentioned visitors (that is, this group photo does not include Persons other than the above-mentioned visitors) are used as the corresponding first face image, but it is not limited to this.

In addition, in one embodiment, after the processor 106 receives the first face image GM1 uploaded by the visitor G1, it can determine whether the number of faces appearing in the first face image GM1 matches the visitor G1 and fill in the visit application. The number of visitors. If it is, the processor 106 may determine that the first face image GM1 of the visitor G1 has been obtained, otherwise, it may request the visitor G1 to upload again, but it is not limited to this.

In one embodiment, after determining that the first face image GM1 and the above-mentioned interview information are obtained, the processor 106 may ask the interviewee V1 whether to approve the interview application. For example, the processor 106 can notify the interviewee V1 of the contact information (such as name, phone number, email, affiliation, etc.) and visit time of the visitor G1 in a text message or email, so that the interviewee V1 can determine whether to agree or not. Visit application submitted by visitor G1.

If the interviewee V1 agrees to the visit application of the visitor G1, the processor 106 may correspondingly send a visit application success message to the electronic device of the visitor G1. On the other hand, if the interviewee V1 disagrees with the visit application of the visitor G1, the processor 106 may cancel the visit application and send an access application failure message to the electronic device of the visitor G1, but the present invention is not limited to this.

After that, in step S220, the processor 106 may obtain the second face image VM1 of the interviewee V1. In one embodiment, the second face image VM1 is, for example, the face image uploaded by the interviewee V1 to the visitor authentication device 100 in advance, and the face image is, for example, the ID photo of the interviewee V1 stored in the system of the company to which the interviewee V1 belongs. /Portrait/Selfie, etc., but not limited to this.

Then, in step S230, the processor 106 may shoot the first specific image PH1 of the visitor G1 and the interviewee V1, and recognize a plurality of first human faces F1, F2 in the first specific image PH1. In one embodiment, before the visitor G1 enters the above-mentioned specific field, the processor 106 may request a group photo of the visitor G1 and the interviewee V1 to be taken as the first specific image PH1. For example, the processor 106 may request the visitor G1 and the interviewee V1 to stand together at a designated check-in point, and then take a group photo of the visitor G1 and the interviewee V1 as the first specific image PH1, but it is not limited to this.

After that, in step S240, in response to determining that the aforementioned first face F1 and F2 match the first face image GM1 and the second face image VM1, the processor 106 may determine that the visitor G1 is authenticated.

In one embodiment, in response to determining that the visitor G1 is authenticated, the processor 106 may correspondingly allow the visitor G1 to enter the above-mentioned specific field (for example, open the gate), but it is not limited to this.

In another embodiment, in response to determining that the aforementioned first face F1 and F2 do not match the first face image GM1 and the second face image VM1, the processor 106 may determine that the visitor G1 has not passed the authentication, and prohibits it accordingly The visitor G1 enters the above-mentioned specific field, but it is not limited to this.

Specifically, before the visitor G1 wants to leave the above-mentioned specific field, the processor 106 may further request to take another group photo of the visitor G1 and the interviewee V1 as the second specific image, and identify the majority of the second specific image. A second face. Afterwards, in response to determining that the aforementioned second human face matches the first human face image GM1 and the second human face image VM1, the processor 106 can correspondingly allow the visitor G1 to leave the specific field, but it is not limited to this. In addition, when the processor 106 allows the visitor G1 to leave the above-mentioned specific field, the personal data previously provided by the visitor G1 can also be deleted, but it is not limited to this.

In addition, although a single visitor G1 is used as an example for description above, a person with ordinary knowledge in the field should be able to understand the implementation of verifying multiple visitors at the same time based on the above teachings. For example, when multiple visitors want to visit interviewee V1 at the same time, the processor 106 can obtain individual facial images (such as selfies) of these visitors based on previous teachings, and before these visitors enter the above-mentioned specific field , Ask these visitors to take a group photo with interviewee V1 (ie, the first specific image). After that, the processor 106 can recognize whether the multiple faces in the group photo match the face images provided by the visitors and the second face image VM1 of the interviewee V1. If so, the processor 106 can determine that these visitors have passed the authentication, and can correspondingly allow these visitors to enter the above-mentioned specific field. Otherwise, it can determine that these visitors have not passed the authentication and prohibit these visitors from entering the above-mentioned specific field.

In another embodiment, after obtaining the aforementioned group photo and recognizing the human faces therein, the processor 106 may also first determine whether the number of human faces matches the number of visitors and the total number of interviewees. If the number of faces does not match the number of visitors and the total number of interviewees, the processor 106 may directly determine that the visitors have not passed the authentication, and prohibit these visitors from entering the specific field. For example, assuming that the number of visitors previously provided by the visitor G1 is 1 person, there should be only 2 persons in the above group photo (that is, 1 visitor G1 and 1 interviewee V1). Therefore, if the processor 106 determines that the number of recognized faces is not 2, it can directly determine that the visitor has not passed the authentication (for example, there are more visitors). For another example, assuming that the number of visitors previously provided by visitor G1 is 3, there should be only 4 people in the above group photo (that is, 3 visitors and 1 interviewee). Therefore, if the processor 106 determines that the number of recognized faces is not 4 (for example, there are more visitors or a few visitors are missing), it can directly determine that the visitor has not passed the authentication.

In addition, when the aforementioned visitors want to leave a specific area, the processor 106 may also request these visitors to take another group photo with the interviewee V1. After that, the processor 106 can recognize whether the multiple faces in the another group photo match the face images provided by the visitors and the second face image VM1 of the interviewee V1. If so, the processor 106 can determine that these visitors have passed the authentication and can correspondingly allow these visitors to leave the above-mentioned specific field. Otherwise, it can determine that these visitors have not passed the authentication and prohibit these visitors from leaving the above-mentioned specific field.

In summary, the present invention has at least the following features: (1) By taking a group photo of the interviewee and the visitor, the existing visitor's renewal and sign-in process can be obtained, and the visitor and the interviewee can enter and exit a specific venue together. (2) Because the visitor can provide relevant information in advance, the present invention can avoid the tedious and error-prone process of manually creating files on site when the visitor visits, and does not need to keep the visitor's credentials, thereby avoiding the issue of credential theft; ( 3) The present invention does not require guards to assist in managing the visitor's entry and exit, which is beneficial to shorten the time for authenticating visitors and reduce unnecessary guard manpower waste; (4) The present invention can be based on a group photo of the visitor and the interviewee while at the same time The identification of multiple visitors can make the meeting process more time-saving and efficient; (5) The present invention allows visitors to visit specific venues without issuing meeting cards, thus solving the problem of non-owner holding visitor certificates , And issues such as missing or wrong visitor cards.

In addition, through the technical means of the present invention, when a visitor wants to enter and leave a specific area, the interviewee and the visitor need to take photos together for authentication, and only after passing the authentication can they enter or leave the specific area. Being accompanied by interviewees can prevent visitors from accidentally entering non-permitted areas and ensure the safety of specific venues.
