It relates to a method, apparatus and system for protecting portrait rights.

Recently, with the development of information technology and the introduction of ubiquitous computing, modern society has gone beyond the infrastructure based on public service networks (electricity, gas, water and sewage, etc.) connected by various pipes or physical lines to public services, content and new additions. We are paying attention to cutting-edge information and communication networks that can deliver high added value by delivering services.

In addition, as society develops, crimes are becoming more intelligent and faster, and violent and unmotivated crimes are also becoming more frequent. Due to the nature of these crimes, it is not easy to find witnesses or evidence, and there are many difficulties in securing statements.

CCTV (Closed-Circuit Television) cameras have been introduced to monitor crime in such situations and to improve social safety issues. It is gradually expanding.

CCTV cameras can be used as evidence of crime by taking action when an incident occurs while monitoring and storing images in real time by using a monitor agent for a wide area or by searching the stored images after an incident occurs.

In addition, recently, a system that uses a vehicle black box to photograph an accident that occurs during driving or parking requested by a vehicle is used for purposes such as CCTV.

However, since these CCTVs or black boxes are for shooting an unspecified number of people, they are included in the video even if the person does not want to be photographed in the video, and may be unintentionally disclosed if necessary.

Therefore, it is difficult to guarantee the right of portrait of an individual who does not want to be disclosed. Recently, for the protection of personal portrait rights, a technology has been developed in which the person in charge of image processing mosaics all other people except for the part to be disclosed in the image and covers the face, but this consumes a lot of human and time, and reveals whose face and whose face is disclosed. There is a problem that the person in charge has to check whether the face is covered or not.

The user identification information may be an ID corresponding to the user's account. The portrait image information may be one or a plurality of photos or moving pictures of a user's portrait. The portrait image information may be used as basis data for identifying the user in the image photographed by the image capturing unit 30 .

The portrait disclosure setting information corresponding to the user is information for setting whether to disclose or not disclose the user's portrait in the image captured by the image capturing unit 30, for example, "public/private", "True" /False", "Yes/No", "Non-Hidden/Hidden", etc. can be set.

Next, the server 20 may store the received user identification information corresponding to the user, the user's portrait image information, and the portrait public setting information corresponding to the user in the database 26 (step: S2).

Meanwhile, the image capturing unit 30 may capture an image, and the captured image may include a small image of the user. The image capturing unit 30 may transmit the captured image to the server 20 , and the server 20 may receive the captured image from the image capturing unit 30 (step: S3 ).

Next, the server 20 may detect the user's portrait among the objects in the received image based on the user's portrait image information stored in the database 26 or learned by artificial intelligence. (Step: S4).

The server 20 may perform a hidden process on the detected portrait of the user based on the portrait disclosure setting information (step: S5). For example, when the portrait disclosure setting information is set to not disclose a portrait corresponding to the user, the server 20 may perform a hidden process so that the user's portrait is not shown. On the other hand, when the portrait disclosure setting information is set to disclose a portrait corresponding to the user, the server 20 may not perform hidden processing on the user's portrait.

The hidden processing for the user's portrait is to cover the user's portrait so that the user's portrait is not shown when the captured image is reproduced, and may be, for example, mosaic processing, block processing, or the like.

Meanwhile, the server 20 may receive contact information corresponding to the user from the user terminal 10 and store it in association with user identification information in the database 26 , and information related to whether or not to perform hidden processing based on the stored contact information By sending the , it is possible to inform the user of the relevant contents. For example, when the user terminal 10 is a mobile phone, the contact number may be a phone number corresponding to the user terminal 10 . The server 20 may inform the user terminal 10 of the processing result through text, messenger, voice guidance, etc. .

Meanwhile, the server 20 may receive a request for information about the user's portrait that has been hidden from the image reproducing unit 40 . In this case, the server 20 may transmit at least one of user identification information corresponding to the user, portrait image information of the user, and contact information corresponding to the user to the image reproducing unit 40 in response to the information request. there is.

For example, if you want to check the identity of the user in order to check whether there is a relationship between the user and the criminal while the video playback unit 40 reproduces the captured image to check the CCTV during the investigation of theft case, the video playback unit 40 transmits a request for information about the user's portrait, and the server 20 reproduces image information such as user identification information corresponding to the user, portrait image information of the user, and contact information corresponding to the user in response to the request It is to be transmitted to the unit (40).

Meanwhile, the server 20 may store the part of the user's portrait hidden in the captured image with the user identification information and stored in the database 26 . For example, since it is not possible to visually determine who the user's portrait part is covered by after the hidden processing, the server 20 stores the hidden part of the user's portrait in case it is necessary to check the user. It associates user identification information.

4 is a flowchart illustrating a flow of an image processing method for protecting portrait rights according to a preferred embodiment of the present invention. Hereinafter, a method of disclosing or disclosing a portrait for each individual in an image in which a plurality of portraits are captured will be described.

As shown in FIG. 4 , the server 20 may receive the captured image from the image capturing unit 30 through the interface (step: S11 ). In this case, it may be assumed that the captured image includes portraits corresponding to a plurality of users. Then, the processor of the server 20 may identify a plurality of portraits in the captured image (step: S12). Next, the server 20 may detect a plurality of user identification information corresponding to the identified plurality of portraits (step: S13).

5 is a flowchart exemplarily illustrating a process of detecting a plurality of pieces of user identification information by the server 20 .

Referring to FIG. 5 , for example, the server 20 searches the database 26 storing portrait image information for each user and detects a plurality of users' portrait image information that matches the identified plurality of portraits. There is (step: S21). Subsequently, the server 20 may detect a plurality of user identification information corresponding to the detected portrait image information of the plurality of users (step: S22). The user-specific portrait image information may be at least one of a user-specific photo and video.

Next, the server 20 may perform a hidden process on at least one portrait based on the plurality of portrait disclosure setting information corresponding to the detected plurality of user identification information (step: S14).

6 is a flowchart for exemplarily explaining a process in which a hidden process for at least one portrait is performed by the server 20 . As shown in FIG. 6 , the server 20 may detect at least one portrait set to not reveal the portrait among the plurality of portraits based on the plurality of portrait public availability setting information (step: S31) ). Subsequently, the server 20 may perform a hidden process on the detected at least one portrait (step: S32).

7 is an exemplary diagram illustrating a state in which a hidden process is performed on at least one portrait in an image captured by the image reproducing unit 40 .

As shown in FIG. 7 , the captured image includes portraits of four users, for example, a portrait of a first user (U1), a portrait of a second user (U2), a portrait of a third user (U3), and the second 4 User portraits (U4) are included.

Among them, the portrait disclosure setting information corresponding to the first user and the portrait disclosure setting information corresponding to the fourth user do not matter if the portrait is published, and it corresponds to the portrait disclosure setting information corresponding to the second user and the third user. If it is assumed that the portrait disclosure setting information is set to not reveal the portrait, as in the example shown in FIG. 7 , the portraits of the first and fourth users are public, while the portraits of the second and third users are public. can be reproduced by mosaic processing.

Meanwhile, the server 20 may receive a request to release the hidden for the hidden-processed portrait from the image reproducing unit 40 . In response to the request for information, the server 20 may release hidden processing for the requested portrait to be displayed.

8 is an exemplary diagram for explaining an example in which the hidden release is performed by the server 20 that has received the hidden release request.

Referring to FIG. 8 , for example, when a third user who was checking the playback image shown in FIG. 7 wants to check the hidden-processed appearance of the user and inputs the previously set password using the third user terminal, the hidden The release request may be transmitted to the server 20 .

Then, in response to the request for releasing the hidden information from the third user terminal, the server 20 may release the hidden processing for the requested portrait to be displayed. Accordingly, as shown in FIG. 8 , the portrait U3 of the third user is hidden from the captured image according to the authenticated request from the third user terminal and is normally displayed.

Meanwhile, the server 20 may receive a request for information about the hidden-processed portrait from the image reproducing unit 40 . In response to the information request, the server 20 retrieves at least one of user identification information corresponding to the hidden-processed portrait, portrait image information corresponding to the hidden-processed ancestor, and contact information corresponding to the hidden-processed portrait. It can be transmitted to the image playback unit (40).

Meanwhile, the server 20 may store in the database 26 the part of the user-specific portrait that has been hidden in the captured image in association with the corresponding user identification information. For example, since it is not possible to know who is covered by the portrait part for each user after the hidden process, the server 20 stores the hidden part of the user's portrait part in case it is necessary to identify a specific user. It associates identification information.

Although the present invention has been described by exemplifying preferred embodiments thereof, those skilled in the art can variously modify and change the present invention within the scope without departing from the technical matters and scope of the present invention described in the claims below.
