In the following, specific embodiments of a method and apparatus for image authentication will be described.

In recent years, when conducting second-hand transactions or financial transactions, the need for image-based authentication of goods and personal authentication of users has increased, and in addition to this, the need for image-based authentication of location and time has also increased.

In the case of digital content, it is extremely easy to copy and distribute without permission, making it difficult to guarantee the right to display the name of the original author.

This embodiment is intended to solve problems such as forgery and theft of images, and when transmitting an image, it is authenticated as a directly photographed image, and an automatic NFT (Non-fungible token: The purpose is to support the issuance of non-fungible tokens.

In this specification, an image may refer to content generated by a camera, including photos and videos.

The computer device 200 according to the present embodiment may provide a messenger service to a client by accessing a dedicated application installed on the client or a web/mobile site associated with the computer device 200. The computer device 200 may be configured with a computer-implemented image authentication system. For example, the image authentication system may be realized in the form of a program that operates independently, or may be configured in the form of an in-app of a specific application and runs on the specific application. It may be implemented as possible.

The processor 220 of the computer device 200 may be implemented as a component for executing the following image authentication method. Depending on the embodiment, components of processor 220 may be selectively included or excluded from processor 220. Also, depending on the embodiment, components of processor 220 may be separated or combined to express the functionality of processor 220.

Such processor 220 and components of processor 220 may control computing device 200 to perform the steps included in the image authentication method below. For example, processor 220 and components of processor 220 may be implemented to execute instructions according to operating system code and at least one program code that memory 210 contains.

Here, the components of processor 220 may be representations of different functions that are performed by processor 220 according to instructions provided by program code recorded on computer device 200.

Processor 220 may read the necessary instructions from memory 210 loaded with instructions related to controlling computer device 200 . In this case, the loaded instructions may include instructions for controlling the processor 220 to perform the steps described below.

The steps included in the image authentication method described below may be performed in a different order than shown in the figures, and some steps may be omitted or additional steps may be included. .

Although the steps included in the image authentication method may be performed on the client, at least some of the steps may be performed on the server 150 in some embodiments.

FIG. 3 is a flowchart illustrating an example of a method that may be performed by a computing device in an embodiment of the invention.

Referring to FIG. 3, at step 310, processor 220 may utilize a camera event in a chat room on Messenger to authenticate the direct capture of an image captured by a camera. When the processor 220 identifies an image that the user wants to send in the messenger, the processor 220 may check whether the image is an image taken directly by a camera of the electronic device on which the messenger is installed. As an example, if an image is captured by executing a camera function configured in the in-app format of Messenger in a chat room, the processor 220 may determine that the image is an image captured directly by the event that executed the in-app camera. You can certify that something is true. As another example, if the image is taken by running the system camera of the electronic device on which Messenger is installed, the processor 220 may determine whether the image is an image taken directly by a camera event provided by the operating system (OS). You may authenticate that it is.

In step 320, if the user requests the transmission of the image in the chat room after capturing the image, the processor 220 may transmit the image including an authentication mark of direct shooting authentication. That is, the processor 220 may send an image directly taken by the user to a messenger server (e.g., server 150, etc.), which causes the messenger server to send the image directly to the electronic device of the member participating in the corresponding chat room. You may submit images that include the Direct Photography Certification Mark. As another example, the processor 220 may generate an image that includes a certification mark for an image taken directly by the user, and place the certification mark of the shooting directly on the electronic device of a member participating in the relevant chat room. You may send an image containing it. Subsequently, the processor 220 sends at least one of image information of the photographed image, meta information of the photographed image, encryption information of the photographed image, or certification mark information of the image including the certification mark to the messenger server. (for example, server 150, etc.). It is of course possible to send an image with the certification mark directly included in the image, but it is also possible to send the image with the authentication result of direct photography included in the metadata instead of the certification mark.

The processor 220 may provide editing functionality for directly captured images in a chat room, and in the case of directly captured images, may provide editing functionality limited to a range where the content of the image is not corrupted. For example, editing functions that do not transform the image itself, such as resize, crop, rotate, and display correction, are allowed, but additions such as doodles and image filters are allowed. Editing functions such as (image filter) that modify the contents of an image may be restricted (prohibited). In addition to restricting editing functions for directly photographed images, edited images that provide free editing functions but whose original content has been modified beyond a certain level are excluded from certification as directly photographed images. You can do it like this.

In step 330, when displaying the image requested by the user in the chat room, if the image is directly taken by the user, the processor 220 may display the image together with a certification mark for the direct shooting. When the processor 220 directly sends and receives a photographed image in a chat room, the processor 220 uses the UI (user interface) in the chat room to easily recognize that the image has been authenticated as having been directly photographed. Images may be displayed in sections.

FIG. 4 is a diagram illustrating an example of a chat room screen that displays directly photographed images in an embodiment of the present invention.

Referring to FIG. 4, when the user sends an image 410 directly taken by the user using the camera of the electronic device installed with Messenger in the chat room 400 on Messenger, the processor 220 converts the image 410 sent by the user into the chat room 400 on the messenger. When displayed in the chat room 400, an authentication mark 411 may be displayed to certify that the image 410 was directly taken by the user.

Processor 220 may be configured to transmit image 410 from chat room 400 to another chat room, or to transmit image 410 through a different medium than the messenger in which chat room 400 was included (e.g., other messenger, text service, other social service, etc.). ), the authentication mark 411 may be removed from the image 410. That is, when the image 410 with the direct photography authentication mark 411 is retransmitted or shared externally, the image 410 may be sent with the direct photography authentication mark 411 removed.

As another example, if the image 410 taken directly by a user is sent by this user to other chat rooms within Messenger or shared on other media in conjunction with Messenger, the processor 220 may directly The image may be transmitted while the photographing authentication mark 411 is maintained.

FIG. 5 is a diagram illustrating a process of issuing an NFT for an image according to an embodiment of the present invention.

Referring to FIG. 5, in step 501, the processor 220 may issue an automatic blockchain-based NFT for the image for which the direct capture is authenticated if the image is requested to be sent in the chat room after capturing the image. . Processor 220 may issue naming rights in the NF that are proprietary to the original author of the image. The processor 220 captures the image by recording on the blockchain a smart contract that includes a contract address, a token ID, and a token URI (Uniform Resource Identifier) for the image that has been authenticated for direct capture. You may issue an NFT indicating the right to display your name.

In step 502, the processor 220 may attach NFT information issued for the image to the meta information of the image requested by the user, and transmit the meta information to the messenger server. That is, the processor 220 may support authentication of the image by attaching NFT information to meta information such as an exchangeable image file format (EXIF) of the image. An image sent in a chat room may include NFT information for this image, and may include identifying information about the original author of the image (e.g., profile URL on Messenger, account ID, etc.) for purposes of querying within Messenger. You can let me. NFT information may be queried from images sent in chat rooms.

Although the above-described NFT issuance process is described as being executed on a client in which Messenger is installed, the NFT issuance process is not limited thereto, and may be executed on the server 150 depending on the embodiment.

FIG. 6 is a diagram illustrating another example of a chat room screen displaying a directly photographed image according to an embodiment of the present invention.

The processor 220 may add authentication using a watermark to the image directly taken and sent by the user.

Referring to FIG. 6, when the user sends an image 410 directly taken using the camera of an electronic device in which Messenger is installed in a chat room 400 on Messenger, the processor 220 converts the image 410 sent by the user into a chat room 400 on Messenger. When displayed in the chat room 400, a watermark 611 may be displayed to authenticate that the image 410 was directly taken by the user.

Processor 220 may transmit and display a watermark 611 that includes NFT information (eg, token ID) on image 410 itself. When displaying the image 410 in the chat room 400, a watermark 611 may be used to indicate that the image 410 is an image that has been authenticated for direct capture and for which an NFT has been issued.

Watermark 611 may be added to be displayed on image 410 itself so that the authentication information is maintained even if the image 410's metadata is deleted. When attaching authentication information for shooting directly to the metadata of the image 410, the authentication information may be lost during the process of changing or updating the metadata, so a watermark 611 is inserted on the image (410). Authentication information for direct photography may be maintained in a manner that

In the case of a video, a watermark 611 may be added to each key frame included in the video.

Although not shown in the figure, the processor 220 may further display an NFT-related UI on the image 410 indicating that the NFT is issued in connection with direct photography. If such an NFT-related UI is selected, processor 220 queries NFT issuance history through a messenger server (e.g., server 150, etc.) or an NFT management server (e.g., server 160, etc.) to determine image generation and previous related information may be displayed in pop-ups or other pages. This can provide historical information regarding the user who originally captured or distributed the image.

FIG. 7 is a diagram for explaining the process of displaying original author information on an image in an embodiment of the present invention.

Referring to FIG. 7, in step 701, the processor 220 may check the original author information included in the directly captured image when receiving and displaying the image in the chat room. As an example, in the case of a directly photographed image, identification information of the original author may be sent along with the NFT information, and the original author of this image may be able to communicate with the user on Messenger (e.g., friend relationship, registration relationship). etc.) is the set user (hereinafter referred to as a "friend").

In step 702, if the image received in the chat room is a directly captured image and the original author of this image is a friend who has established a relationship with the user on Messenger, the processor 220 displays a friend mark along with a friend mark. You may display this image in the chat room. The processor 220 may display a friend mark with the image to distinguish when the original author of the image sent in the chat room on Messenger is a friend of the messenger from a case where the original author is not a friend of the messenger. If the original author of the image sent in the chat room on Messenger is a friend of the messenger, the processor 220 may display the friend status through a UI associated with the image so that the original author can be easily identified. . At this time, the processor 220 may display the Messenger profile of the friend who is the original author with a friend mark for the directly photographed image sent by the Messenger friend. In some embodiments, display elements (eg, image frames, etc.) of images sent by friends on Messenger may be highlighted instead of the friend mark to distinguish them from general images. In such cases, the additional information on the image would indicate that the original author of the image is a friend. For example, if a user selects an image with a highlighted display element in a chat room, the original author's Messenger profile may be provided in a pop-up to indicate that the original author is a friend as additional information for the image.

FIG. 8 is a diagram illustrating an example of a chat room screen displaying a directly photographed image including original author information, according to an embodiment of the present invention.

Referring to FIG. 8, the processor 220 displays the image 410 received in the chat room, and at this time, if the image 410 is authenticated as a directly captured image, the processor 220 checks the original author information and the original author is displayed on the messenger. If the user is a friend of the original author, a friend mark 811 composed of the original author's profile image may be displayed so that the original author can be easily recognized.

When displaying the image 410 in the chat room 400, this image 410 is a directly photographed image, and a friend mark 811 may be used to indicate that the friend on the messenger is the original author.

The authentication of direct image capture according to the present invention can be utilized for personal identification when conducting second-hand transactions or financial transactions. For example, it can be used to authenticate that you actually own the item when making a second-hand transaction. In addition, it can be used not only for authentication to prove that the content of the image is original, that it is an unaltered image, and the time when the image was taken, but also for the original source of the image leaked on the Internet. It can also be used to prove authorship.

As described above, according to the embodiments of the present invention, when an image is photographed and transmitted, it is possible to solve problems such as image forgery and theft by providing an authentication result for the photographed image. Further, according to the embodiment of the present invention, by issuing a blockchain-based NFT for a directly photographed image, the right to display the original author's name can be guaranteed.
