In the present invention, a digital image does not only mean a single image but also includes an image (for example, an image frame included in a moving image) that can be provided by a moving image or other method.
The
The object to be photographed by the digital image may be an identification card, a user's card or other object expected to be occupied by the user, or may be a physical object (e.g., a face, etc.) Objects, and so on.
The present invention can be used for non-face-to-face authentication. In this case, the digital image transmitted by the

The
In this specification, a module may mean a functional and structural combination of hardware for carrying out the technical idea of the present invention and software for driving the hardware. For example, the module may refer to a logical unit of a predetermined code and a hardware resource for executing the predetermined code, and it does not necessarily mean a physically connected code or a kind of hardware But can be easily deduced to the average expert in the field of the present invention.

Then, the
According to an embodiment, the
For example, according to an embodiment of the present invention, when an image transmitted to the
According to the technical idea of the present invention, the user authenticates the first object (e.g., ID card) on which his / her face is displayed and the image (or the first object image and the second object image) To the
In this case, an effect similar to offline face-to-face authentication (for example, a process of presenting an ID card off-line and comparing the face of the user face and the ID card with the naked eye by the authentication side) can be obtained. Depending on the implementation, the
Meanwhile, according to the technical idea of the present invention, at least one of the
The image processing may include, for example, scaling one of the first face image (the image included in the identification card) or the second face image (the face image taken by the portable terminal) to the same or similar size as the other one . According to an embodiment of the present invention, an image adjustment process may be included in which an image is changed or an image is filtered so as to have the same or similar color, roughness, or brightness as the other image. In any case, the image processing may be performed in such a way that the image attributes of the first face image and / or the second face image are compared with a relative image (e.g., a second face image in the case of a first face image, Based on the image attributes (e.g., size, color, illuminance, and / or brightness, etc.) of the first face image (which means first face image).
After this image processing process is performed, an editing module (not shown) included in the
The image arrangement process may include arranging the first face image and the second face image after the image processing is performed in a first area and a second area, respectively, which are predefined on a predetermined UI. The first face image and the second face image can be confirmed at the same time through the image arrangement process, thereby increasing the efficiency of the comparison process.
Depending on the implementation, only the image placement process may be performed without the image processing. In this case, the first face image and the second face image may be simply placed in the first region and the second region so that a predetermined solution or user can easily compare the first face image and the second face image.
If the second face image is a plurality of photographs, the arrangement area can be appropriately adjusted according to the number of photographs. For example, an ID photo may be arranged first, a plurality of face photographs may be simply arranged, or a plurality of photographs may be arranged side by side with the ID photo up or down. Or you could put a photo of your ID at the center and put a lot of photos around it. It will be appreciated by those of ordinary skill in the art that the manner of placement may vary.
An example of an image placement process is shown in FIG.

For example, from each of the first face image and the second face image, the editing module can determine each position indicating a specific region. Then, based on the respective positions, the first face image (or the first face image subjected to the image processing) and the second face image (or the second face image processed with the image) can be arranged to overlap with each other. Of course, any one of the face images can be displayed as transparent or translucent. In such a case, the comparison between the facial images can be easily performed depending on whether or not the specific region is displayed overlapping and how much the remaining regions overlap the same or similarly.
In any case, the first area and the second area can be arranged so that the first face image and the second face image can be easily compared with each other.

On the other hand, when a user attempts to authenticate a user by using a first digital image that is an object of a user's face (for example, an ID) and a second digital image that a user's face is photographed, The face image displayed on the object may be adjusted and photographed. In this case, even if a malicious user does not photograph his / her face, the
The technical idea of the present invention provides a technical idea that can distinguish whether a predetermined digital image is an image of a real object or a two-dimensional image such as a photograph of the real object.
According to an exemplary embodiment of the present invention, the object (e.g., ID card) and the face of the user can be simultaneously photographed together with the front camera and the rear camera of the
Alternatively, the
Or whether the
According to an embodiment, when the second digital image is captured, the
Of course, in order that the reflection characteristic of the light may well appear in the image, the
For example, when a photograph is photographed with a fresh light, a relatively large amount of light is reflected on the photographed photograph, or the light emission effect itself by the fresh light appears on the photograph. On the other hand, There may be no phenomenon or it may be relatively small. Therefore, the predetermined solution or staff provided in the
According to the technical idea of the present invention, even if the
To solve this problem, the
In this specification, the case where the illumination device continuously photographs images in the activated state and the inactivated state is mainly described, but depending on the embodiment, the illumination device may be operated in a different illumination state (e.g., It is needless to say that the technical idea of the present invention can also be applied to the case of photographing continuously such that the intensity is different or the kind of illumination is made different).
In any case, the
In addition, when both the illumination active image and the illumination inactive image are acquired, image characteristics due to reflection of light output from the illumination device can be obtained very clearly. For example, when obtaining the difference image represented by the difference of the illumination-inactive image in the illumination-active image, the difference image may well exhibit an image characteristic representing reflection of light or the like, and through the image characteristic, It is possible to clearly distinguish whether the at least two images are an image of a real object or an image of an image by judging whether the image has a characteristic of being photographed or a characteristic of photographing a two-dimensional image.
According to an embodiment, it is possible to judge whether at least one digital image has photographed a physical object by photographing an object to be photographed at a plurality of angles. For example, the face image or the photo displayed on the ID card is usually an image that faces the front face or indicates a certain direction of the object. The
In some cases, an unauthorized user may have images taken at different angles with respect to a specific object, and when the unauthorized user photographs each of the images, the authentication is successful even if the real object of the specific object is not photographed It is possible.
In order to solve such a problem, the
Then, the specific angle or specific distance is controlled by the
Through the above-described technical idea, it is possible to verify a case in which a malicious user captures an image of a photograph or the like (for example, a photograph of an article or a face image displayed on an ID card) without photographing the real object, When the digital image received from the
The technical idea of the present invention which can distinguish whether a predetermined digital image is an image of a real object or an image of a photograph or the like taken by the physical object is not only authentication of the user but also whether or not the real object has been photographed It can be widely used for authentication.
For example, when a user performs a commercial transaction such as a transaction for a used article, there is a case where an image of an article not owned by the seller is uploaded to a predetermined service page to conduct a fraudulent transaction.
In this case, the
For example, the
The
The
At this time, the digital image obtained and transmitted by the
Then, in the authentication image, an image (hereinafter, referred to as an 'illumination active image') in which the object (e.g., an article or a face, etc.) is photographed in a state in which the illumination device Quot;). To this end, the
According to another embodiment, the authentication image may include a plurality of images obtained by photographing the object at different angles as described above. At least one of the plurality of images may be a light-activated image, and all of the plurality of images may be an image (hereinafter, referred to as a 'light-inactive image') in a state in which the illumination device is not activated.
According to the technical idea of the present invention, the
When the illumination active image is used, the
The image characteristics that appear in the image-taking image in the active illumination state may be, for example, an image feature associated with the reflection of the illumination or the like.
For example, in the case of a live image in the active illumination state, the degree of reflection of the illumination may be small or absent, and in the case of the image taken image in the active illumination state, the degree of reflection of the illumination may be large. Or at least the actual image in the illumination active state is different between the degree of reflection of the light of the real object part and the degree of reflection of the background part, The degree of reflection of the portion of the illumination may be substantially the same. Or the live image in the active illumination state, the images of the object portion are homogeneous and clear, while the image taken image may show portions in which a specific portion of the object portion is not homogeneous or unclear. The
The
The learning module may then derive image features that appear in the image capture image in the active illumination state through various types of learning algorithms. For example, the image shown in FIG. 5A is an image pickup image in an illumination active state for a specific object (for example, a remote controller), and the image shown in FIG. 5B is a real object Image.
As can be seen in Fig. 5, the image pickup image in the active illumination state has the same or similar reflected characteristics of the illumination of the object portion (e.g., the remote control portion) and the background portion, For example, the remote control portion) and the reflected characteristics of the illumination of the background portion may be dissimilar. In addition, the real image in the active state of illumination may be such that the images of the object portion are homogeneous and clear, while the image taken image may show portions in which the specific portions of the object portion are not homogeneous and unclear. Therefore, the reflection characteristics of the illumination, such as the difference between the object part and the background part, the difference of the homogeneity and the sharpness of the object part, may be learned as the image characteristics of the image taken image in the illumination active state. It goes without saying that various image characteristics can be learned by the learning module while learning is performed in addition to these characteristics.
After the learning is performed, the
The learning algorithm used by the learning module may be various types of machine learning or deep learning, but is not limited thereto. As described above, any algorithm capable of learning enough to distinguish an image captured image and a real image in an illumination- Can also be used.
On the other hand, when the image characteristic is derived through the learning as described above, the
For example, the
In addition, the illumination active image and the illumination inactive image may be continuously acquired even if the user performs only one photographing operation as described above. Of course, each of the users may perform a plurality of photographing actions. Also, depending on the implementation, the
Also, as described above, the authentication image may include a plurality of images in which the object (e.g., an article held by a user or a user's face) is photographed a plurality of times at different angles. The
According to an example of determining whether the image for authentication is a real image or an image taken image based on a plurality of images, the
In addition, both the image (real image) in which a user's face is photographed for user authentication and the image in which an object (for example, an ID card) on which the user's face is displayed are transmitted from the
As a result, according to the technical idea of the present invention, the
According to the technical idea of the present invention, whether or not the predetermined digital image determined by the
According to an exemplary embodiment of the present invention, the determination process performed by the determination module 170 (i.e., determining whether a predetermined digital image is a real image or an image captured image) may be performed by the
In this case, when the
