Description

Accessor identity unmanned authentication system {UNMANED ENTRANCE SYSTEM}

The present invention relates to an unmanned authentication system for identity of visitors.

In general, an access system is performed at the entrance so that only those who are permitted to visit and who are identified for the purpose of technology leakage, safety, etc. in a company or residential area can enter.

Generally, access systems are performed manually. The access system was a method in which a guide at the information desk checks whether or not the person is entitled to enter, and if there is an access qualification, he or she keeps an item (such as an ID card) that can guarantee one's identity, and then delivers the previously held pass.

However, this method runs counter to the non-face-to-face era, and there are problems with the trend and efficiency of the times because waiting time increases when there are many visitors and it is difficult to secure a waiting space when the place is narrow.

Recently, there has been a movement to introduce an unmanned access system to solve this problem, but it is not easily introduced due to security problems.

Therefore, with respect to the access system, there is a growing voice of desire for an access system that simplifies the procedure, confirms identity upon entry, and shortens inefficient procedures that occur during entry and exit, and emphasizes security.

FIG. 2 illustrates an operation diagram of a system including an unattended user identification device 100 according to an embodiment of the present invention.

According to an embodiment, the present inventor's unmanned identity verification device 100 is installed at an entrance to determine the identity of a person entering or exiting. The unmanned authentication device 100 according to an embodiment receives and stores preset identity information, generates proof information using a person's identity authentication object, compares the identity information and the proof information, and checks whether or not they match. You can check whether access is possible or not.

Looking at the present invention in more detail with reference to FIG. 2 , the present invention may include a management server 10 and an unattended identity verification device 100 .

The user can generate identity information and transmit it to the management server 10 . Here, the identity information may include visit date information, company name information, phone number information, identification object information, photo information, name information, date of birth information, issuance date information, and fingerprint information. Here, the user can directly create and input identity information with the unmanned identity verification device 100 or transmit the identity information to the management server 10 using various other devices.

The management server 10 may check identity information and check whether visitation is possible. Here, if the user's visit is possible, the management server 10 may generate visit approval information. Here, the visit approval information may be transmitted to the unattended identity verification device 100 . Or it can be delivered to various other devices of the user.

And if the management server 10 can generate visit rejection information. Then, the management server 10 may transmit the information to the unmanned authentication device 100 for the identity of the visitor. Or it can be delivered to various other devices of the user.

Then, the user can generate identity information again and transmit it to the management server 10 . Among the information included in the identity information transmitted by the user, visit date information may be different from previous information.

3 illustrates a step of generating identification information by an unmanned authentication device for the identity of an unattended person of the present invention according to an embodiment.

FIG. 4 illustrates setting an area from which an image is extracted by an extraction unit of an unattended user identification authentication device according to an embodiment of the present invention.

According to an embodiment, the present inventors' unattended identity verification device 100 may include a camera unit 110 and an extraction unit 120 . When the user visits the company according to the visit date information included in the identification information, the camera unit 110 may generate photographic information by photographing an object proving identity and a face.

In the present invention, an image of a specific part in photographing information is extracted, and characters (data) can be extracted by using pre-processing, OCR S/W operation, and post-processing. That is, the operation rate of the OCR S/W can be increased by modifying the captured image, and the accuracy of the extracted data can be increased by modifying the finally derived data.

That is, the present invention extracts an image of a specific part of photographing information and extracts data from the extracted part.

The camera unit 110 of the unattended authentication device 100 generates photographing information. Then, the unmanned authentication device 100 operates to check whether the photographed object is a resident registration card, a driver's license, or an alien registration card. That is, according to the present invention, the type of object is first checked, and then the area to be captured can be set.

If the object proving identity is a resident registration card as shown in (a) of FIG. 4, it may be photographed as shown in (a) of FIG. In this case, as shown in (a) of FIG. 4, images of parts A, B, C, and D of photographing information may be captured.

As shown in (b) of FIG. 4 , when the identification object is a driver's license, the user's information may be different. In this case, as shown in (b) of FIG. 4 , images of parts A, B, C, and D of photographing information may be extracted.

In addition, if the user is a foreigner, the foreigner registration card may be an object proving the identity. In this case, it is the same as in (c) of FIG. 4, and images of parts A, B, C, and D can be extracted even at this time.

Thereafter, the extraction unit 120 may extract data from the corresponding image using a pre-processing operation, an OCR S/W operation, and a post-processing operation.

Here, the extraction unit 120 may perform correction processing (pre-processing) before or after extracting data from the image. That is, the extraction unit 120 may perform a correction operation after extracting a specific image from the photographing information.

Here, the extraction unit 120 may perform a correction operation only on a specific image for which data extraction is not performed without performing a correction operation on all images.

(Perform pre-processing operation)

Here, the correction performed by the extraction unit 120 may be color correction. That is, the extractor 120 may perform color correction using the image, and then perform rotation and angle correction by examining distortion of the image. This is because the data becomes clearer by correcting the color of the data, and thus the numerical value of the degree of distortion can be accurately confirmed.

(After treatment)

Also, the extractor 120 may correct data itself. For example, the extraction unit 120 may extract data using previously stored contrast information when data in an image is recognized even if a correction operation is performed or not.

That is, the extraction unit 120 includes contrast information through previous learning, and in the contrast information, data that is inclined in various shapes or has problems is stored. Therefore, the extractor 120 compares the contrast information with the data extracted from the image, and when the corresponding data is unidentifiable or difficult to identify, it can be extracted by loading data corresponding to the corresponding data from the contrast information.

Therefore, the extraction unit 120 can prevent erroneous identification and extraction of erroneous data.

In addition, the extraction unit 120 may detect whether personal information is included in the data after performing a data correction operation when extracting the data.

As such, the extraction unit 120 may generate proof information using the image.

5 is a diagram showing that the present inventor's unmanned identity authentication system determines identity according to an embodiment.

The determination unit 130 has a preset API program. Therefore, the determination unit 130, for example, if the object proving the identity is a resident registration card, it is possible to determine whether or not the fake identity is obtained by using the date of birth information and the issuance date information using the API program.

Here, the date of birth information and the issuance date information may not be a problem even if any one of identification information previously transmitted by the user or proof information generated by the extraction unit 120 is used.

Here, the determination unit 130 may, for example, determine whether or not a forged identity is obtained by using a serial number of the driver's license when the object proving the identity is a driver's license.

Here, the determination unit 130 may determine whether or not a counterfeit identity is obtained by using date of birth information, issuance date information, alien registration number information, etc., when the object proving identity is, for example, a foreigner ID card.

The determination unit 130 may check the identity by comparing the transmitted identity information with the authentication information extracted and generated by the extraction unit 120 .

That is, the determination unit 130 of the unmanned authentication device 100 of the present inventor extracts the identity authentication object information, photo information, name information, date of birth information, and issuance date information from among the identity information transmitted by the management server 10. Identity information can be verified by comparing name information, date of birth information, and issuance date information within the authentication information generated by the unit 120 .

In addition, the determination unit 130 may determine whether or not the user's identity is determined by comparing photographic information and photographic information in which the user's face is photographed.

Afterwards, if there is no problem, it is possible to determine whether to approve the visit by authenticating whether or not the user is allowed to enter.

In addition, the determination unit 130 may perform a three-step authentication procedure.

Step 1 of the determination unit 130

Comparison of input information and identification information (visit date information, company name information, phone number information, identification item information, name information, date of birth information, issuance date information)

Step 2 of the determination unit 130

Comparison of face information (including preprocessing such as correction) included in photographing information through an object and photographing information using the camera unit 110

3 steps of judgment unit 130

Compare and contrast the fingerprint information on the identification card photographed by the photographing unit 110 with the actual fingerprint of the visitor

The determination unit 130 may randomly perform one or more of the three steps described above. That is, the determination unit 130 may perform step 1, then step 3 and step 2, or step 2 may be performed first, and then step 1 and step 3 may be sequentially performed, or otherwise, all of the steps may be performed at the same time. After scaling the data, you can perform the same steps as above.

After performing the same operation as in FIG. 5 , the unattended identity authentication device 100 according to the present invention can perform learning by performing the following operations.

Using the image extracted by the extraction unit 120, a positive sample group and an image mismatched or a negative sample group irrespective of a matching format may be generated.

Then, based on the input sample group, a training data file may be generated through image learning. This is because the recognition rate can be improved in proportion to the number of samples.

After loading the format data file in the extraction unit 120, it is converted into a 300 DPI jpg format and stored. Here, you can change the resolution according to the environment file option of the format classification.

Afterwards, the learning data image and the image format recognition target image are corrected in gray form, and the features in the document (extracted image data) such as text, line, and object are analyzed and automatically classified into a format with high similarity.

Although the present invention has been shown and described in relation to specific embodiments, it is known in the art that the present invention can be variously improved and changed without departing from the technical spirit of the present invention provided by the claims below. It will be self-evident to those skilled in the art.
