Hereinafter, methods and/or systems for protecting a content copyright in a chatroom according to some example embodiments is described.

The term “chatroom” used herein may refer to an interface screen for providing messages exchanged between users for example, an interface screen of a chat function capable of exchanging messages through a communication session established between accounts of users in a messenger or a social network service (SNS), and an interface screen of an open chat function capable of making an immediate chat using a link (e.g., a uniform resource locator (URL) without a friend addition function using a telephone number or an identifier (ID). An open chat link may include a function capable of executing a chatroom of a corresponding link by automatically executing a messenger to immediately initiate a chat in response to a click on the link.

Hereinafter, although description is made based on an example of a chatroom of a messenger, it is provided as an example only. Any type of chat-based interfaces of a service in which a plurality of users participate and newly joins frequently occurs using an account or a telephone number of a user as well as a link.

FIG. 3 is a diagram illustrating an example of components includable in a processor of an electronic device according to at least one example embodiment.

A content protection system implemented by a computer may be configured in the electronic device 110. For example, the content protection system may be configured in a form of a program that independently operates or in an in-app form of a specific application to be operable on the specific application and may provide a messaging service through interaction with the server 150.

The content protection system configured in the electronic device 110 may perform the following content protection method in response to an instruction provided from an application installed on the electronic device 110.

Referring to FIG. 3, to perform the content protection method according to some example embodiments, the processor 212 of the electronic device 110 may include an event recognizer 310, a notification forwarder 320, a marker 330, a function executer 340, and a content manager 350 as components of the processor 212. Depending on some example embodiments, the components of the processor 212 may be selectively included in or excluded from the processor 212. Also, depending on some example embodiments, the components of the processor 212 may be separated or merged for functional representation of the processor 212.

The processor 212 and the components of the processor 212 may control the electronic device 110 to perform operations included in the content protection method. For example, the processor 212 and the components of the processor 212 may be configured to execute an instruction according to a code of at least one program and/or a code of an OS included in the memory 211.

Here, the components of the processor 212 may be representations of different functions of the processor 212 performed by the processor 212 in response to an instruction (e.g., an instruction provided from an application executed on the electronic device 110) provided from a program code stored in the electronic device 110. For example, the event recognizer 310 may be used as a functional representation of the processor 212 that controls the electronic device 110 to recognize an input event associated with content in a chatroom in response to the instruction.

The processor 212 may read a desired instruction from the memory 211 to which instructions associated with control of the electronic device 110 are loaded. In this case, the read instruction may include an instruction for controlling the processor 212 to perform the content protection method.

FIG. 4 is a flowchart illustrating an example of a content protection method performed by an electronic device according to at least one example embodiment.

Referring to FIG. 4, in operation S410, the event recognizer 310 may recognize an input event associated with or predefined in association with content in a chatroom (hereinafter, briefly referred to as a chatroom) of a messenger installed on the electronic device 110. Here, the content may be a target (hereinafter, a copyright protection target) of which a copyright is to be protected, and may inclusively refer to any types of data exchanged between users through the chatroom, for example, a text, an image, a video, and an audio. Herein, to protect a content copyright by preventing image-based content sent in a chatroom or captured image content from being indiscreetly shared, an upload request, a screenshot request, and a sharing request of content among input events in the chatroom may be defined as an instruction for calling a copyright protection function. That is, the event recognizer 310 may recognize the upload request, the screenshot request, and the sharing request that are input events associated with the content in the chatroom as the instruction for calling the copyright protection function.

In operation S420, in response to recognizing the input event corresponding to the instruction for calling the copyright protection function in the chatroom, the marker 330 may add, to content that is a copyright protection target, a mark that includes chatroom information for identifying the chatroom. The mark relates to protecting a copyright for original data (e.g., a text, an image, a video, or an audio) and may be created using a method capable of containing information in a desired pattern, for example, an image and a watermark, a quick read (QR) code, or a barcode. Here, the mark may be created in an image or pattern form recognizable at the server 150 that is capable of tracking a copyright protection target through interaction with the electronic device as represented by 110 in FIG. 2. For example, the marker 330 may create a mark that includes information capable of identifying a chatroom, for example, an ID or a link (e.g., a uniform resource locator (URL)) of a chatroom in which an input event is recognized and may add the mark to content that is specified as the copyright protection target in response to the input event. In response to an upload request, content selected to be uploaded to the chatroom may be specified as the copyright protection target. In response to a screenshot request, content included in a screenshot range of the chatroom may be specified as the copyright protection target. In response to a sharing request, content selected to be shared with another chatroom or another medium through the chatroom may be specified as the copyright protection target. As another example, the marker 330 may create and add a mark that includes information (e.g., a user ID) about an original content creator with chatroom information about the content specified as the copyright protection target. Here, the original content creator may refer to a user that sends an original version of the content specified as the copyright protection target in the chatroom as a content included in the chatroom. Content sent and received through the chatroom may be managed using a unique identifier (a message ID) of a message type. Through this, the marker 330 may identify the content specified as the copyright protection target and the original content creator, and may add the mark that includes information about the original content creator to the specified content. Here, every time the input event is recognized, the marker 330 may receive a mark addition request from the user of the electronic device 110. Depending on some example embodiments, a request for adding a mark to uploaded content may be received in advance as a mark setting.

In operation S430, the function executer 340 may execute a function, for example, an upload function, a screenshot function, and a sharing function, corresponding to the input event recognized in operation S410. That is, in response to the input event recognized in the chatroom, the function executer 340 may upload or capture the content specified as the copyright protection target in a state in which the mark is added and thereby may store or share the content in the chatroom.

Therefore, in response to recognizing the input event, for example, the upload request, the screenshot request, and the sharing request, associated with the content in the chatroom, the processor 212 may add the mark that includes the chatroom information to the content and may perform a function corresponding to the input event using the content to which the mark is added.

FIGS. 5 and 6 illustrate an example of a process of adding a QR code to content according to at least one example embodiment.

Referring to FIG. 5, the marker 330 may add a QR code 501 that includes chatroom information to content 500 specified as a copyright protection target, for example, content to be uploaded to chatroom, content included in screenshot range, or content to share with another chatroom or medium.

Referring to FIG. 6, the marker 330 may provide an edit user interface (UI) 610 for adjusting a size or a position of the QR code 501 added to the content 500. Therefore, the user may directly adjust the size or the position of the QR code 501 added to the content 500 using the edit UI 610. As another example, in addition to allowing the user to directly adjust the size or the position of the QR code 501, the marker 330 may automatically determine the size or the position of the QR code 501 based on a result of analyzing the content 500 using an image-based analysis method. For example, the marker 330 may extract an area in which significant information (e.g., a text or image object) is absent or a background area and may add the QR code 501 to be in the extracted area.

FIG. 7 illustrates an example of a process of adding a watermark to content according to at least one example embodiment.

Referring to FIG. 7, the marker 330 may add a mark that includes chatroom information to the content 500 specified as the copyright protection target. Here, the marker 330 may add a watermark 701 as a different type mark, instead of using a QR code. Likewise, the marker 330 may provide an edit UI that allows the user to directly adjust a size or a position of the watermark 701 added to the content 500, and may automatically determine a size or a position of the watermark 701 based on a result of analyzing an image of the content 500.

Although the description is made by using a QR code and a watermark as some examples of a mark, it is provided as examples only. Any types of marks capable of including chatroom information and protecting a content copyright or tracking the content may apply.

FIGS. 8 and 9 illustrate examples of using content to which a QR code is added according to at least one example embodiment.

Referring to FIG. 8, the electronic device 120 of the user sharing the content 500 to which the QR code 501 is added may provide an access to a chatroom 800 that is a source of the content 500 based on the chatroom information included in the QR code 501, in response to a selection on the content 500 on a screen 80 of the electronic device 120 or recognition of the QR code 501 in the content 500 from a camera of the electronic device 120. If the user of the electronic device 120 is participating in or has joined the chatroom 800, the user may be immediately directed to the chatroom 800. Otherwise, a chatroom introduction screen may be initially provided. A name, a tag, operator information, and a number of participants of the chatroom may be displayed on the chatroom introduction screen. The chatroom introduction screen may include a join request interface for inputting a join request. Therefore, if users not joining the chatroom 800 desire to use the content 500 to which the QR code 501 is added, an introduction screen of the chatroom 800 that is a source of the content 500 may be provided. Because the chatroom information is included in the QR code 501, the QR code 501 may be used for content protection or tracking and also may be used as a method of promoting the chatroom 800.

Referring to FIG. 9, the electronic device 120 of the user sharing the content 500 to which the QR code 501 is added may provide a sharing screen 900 for the content 500 through interaction with the server 150 in response to a selection on the content 500 on the screen 80 of the electronic device 120 or recognition of the QR code 501 in the content 500 from a camera of the electronic device 120. The sharing screen 900 may include tracking information 910 provided from the server 150 for a sharing path of the content 500. Here, the tracking information 910 may include a list of chatrooms having a history of sharing the content 500 and a shortcut link 911 that allows a user to immediately connect to a corresponding chatroom included in the list of chatrooms. Each chatroom may be set to a public state in which access using the QR code 501 is allowed by an administrator (admin) or a private state in which the access using the QR code 501 is disallowed. A chatroom set to the private state in which the access using the QR code 501 is disallowed may be provided with the shortcut link 911 being removed.

If the user selects the shortcut link 911 of the specific chatroom on the sharing screen 900, the electronic device 120 may provide an access to the selected specific chatroom. Here, if the user of the electronic device 120 is participating in or has joined the selected specific chatroom, the user may be immediately directed to the selected specific chatroom. Otherwise, a chatroom introduction screen may be initially provided.

Although description is made based on an example of using content to which a QR code is added, a method of using content to which a different type mark, for example, a watermark, is added may apply in the same or similar manner.

FIG. 10 is a flowchart illustrating another example of a content protection method performed by an electronic device according to at least one example embodiment.

For example, operations S1040 and S1050 included in the content protection method of FIG. 10 may be included in the content protection method of FIG. 4.

Referring to FIG. 10, in operation S1040, the content manager 350 may access a storage space in which a screenshot is stored at a point in time at which a desired period of time (e.g., 10 seconds) elapses based on a point in time at which a screenshot event is recognized. Here, a screenshot storage space may refer to a local storage space allocated to the messenger.

In operation S1050, the content manager 350 may delete content to which a mark is not added, aside from content to which the mark is added from among contents stored in the screenshot storage space during a desired period of time.

Therefore, in response to a screenshot request as the input event associated with the chatroom, the content manager 350 may access the screenshot storage space after a desired period of time elapses and may delete a remaining screenshot excluding the content to which the mark is added.

As another example, the content manager 350 may analyze contents stored in the screenshot storage space and may delete content to which a mark is not added, aside from content to which the mark is added from among contents between which a similarity is greater than or equal to a desired level based on an analysis result. For example, the content manager 350 may classify images stored in the screenshot storage space into similar images based on an image analysis result and may delete a remaining image excluding an image to which a mark is added from among the classified similar images.

The content manager 350 may also access a storage space associated with the chatroom in addition to the screenshot storage space. The storage space is a space in which contents exchanged between users are stored periodically or at a desired point in time. The content manager 350 may delete remaining content excluding content to which a mark is added from among the contents stored in the corresponding space.

FIG. 11 is a flowchart illustrating an example of a content protection method performed by an electronic device according to at least one example embodiment.

Referring to FIG. 11, in operation S1110, the event recognizer 310 may recognize a screenshot request or a sharing request as an input event for content included in a chatroom in the chatroom. Herein, the screenshot request or the sharing request among input events in the chatroom for content copyright protection may be defined as an instruction for calling a copyright protection function. That is, the event recognizer 310 may recognize the screenshot request or the sharing request that is an input event associated with the content as the instruction for calling the copyright protection function in the chatroom.

In operation S1120, in response to recognizing the input event corresponding to the instruction for calling the copyright protection function in the chatroom, the notification forwarder 320 may forward, to an original content creator, a notification for content specified as a copyright protection target for a chatroom content protection. In the case of the screenshot request, content included in a screenshot range of the chatroom may be specified as the copyright protection target. In the case of the sharing request, content selected to share with another chatroom or another medium may be specified as the copyright protection target. Here, the notification forwarder 320 may forward the notification for the screenshot request or the sharing request to an original content creator of the content specified as the copyright protection target. The notification may include chatroom information capable of identifying the chatroom, for example, an ID or a URL of the chatroom in which the input event is recognized. The notification may be forwarded to the electronic device 120 of the original content creator through a separate chatroom or a notification page by interacting with the server 150.

Content sent and received through the chatroom may be managed using a unique identifier of a message type. Therefore, the notification forwarder 320 may identify the content specified as the copyright protection target and may identify a user, that is, the original content creator, which sends an original version of the identified content. At least two original content creators may be identified based on the content specified as the copyright protection target. For example, referring to FIG. 12, the user of the electronic device 110 may designate a screenshot range 1210 with respect to chat contents included in a chatroom 1200. Here, the notification forwarder 320 may select a contact that has sent a message included in the screenshot range 1210 as a target to which a notification is to be forwarded. For example, if a message sent from a user A and a message sent from a user B are included in the screenshot range 1210, the notification forwarder 320 may forward a screenshot notification by the user of the electronic device 110 to the user A and the user B. As another example, the notification forwarder 320 may analyze messages (e.g., chat contents) included in the screenshot range 1210, may identify a simple responder, and may forward a notification to an original content creator who is not the simple responder. The notification forwarder 320 may identify the simple responder who has sent a short or simple reply for example, “ok,” “I see,” “Thanks,” or “Thank you,” among chat contacts having sent messages included in the screenshot range 1210. For example, if a message sent from the user A and a message sent from the user B are included in the screenshot range 1210, the notification forwarder 320 may forward a notification to the user A that provides significant information and may exclude (e.g., may not forward to) the user B that is the simple responder from notification targets.

Referring again to FIG. 11, in operation 51130, once the notification is forwarded to the original content creator of the content specified as the copyright protection target, the function executer 340 may execute a function, for example, a screenshot function or a sharing function, corresponding to the input event recognized in operation S1110. That is, after the notification is forwarded to the original content creator, the function executer 340 may capture and store or share the content specified as the copyright protection target in response to the input event recognized in the chatroom.

Therefore, in response to recognizing an input event, for example, a screenshot request or a sharing request, corresponding to an instruction for calling a copyright protection function in the chatroom, the processor 212 may provide a notification to the original content creator having sent an original version of the content specified as the copyright protection target and then perform a function corresponding to the input event. The original content creator may recognize use of the content by another user, for example, screenshot or sharing of his or her content through the notification. If the original content creator selects the notification, the original content creator may be directed to the chatroom to which the content is sent based on the chatroom information.

FIG. 13 is a flowchart illustrating another example of a content protection method performed by an electronic device according to at least one example embodiment.

Referring to FIG. 13, in operation S1310, the event recognizer 310 may recognize a screenshot request or a sharing request as an input event for content included in a chatroom in the chatroom. That is, the event recognizer 310 may recognize the screenshot request or the sharing request that is an input event associated with the content as an instruction for calling a copyright protection function in the chatroom.

In operation S1320, in response to recognizing the input event corresponding to the instruction for calling the copyright protection function in the chatroom, the notification forwarder 320 may forward, to an original content creator, a notification for content specified as a copyright protection target for a chatroom content protection. In the case of the screenshot request, content included in a screenshot range of the chatroom may be specified as the copyright protection target. In the case of the sharing request, content selected to share with another chatroom or another medium may be specified as the copyright protection target. Here, the notification forwarder 320 may forward the notification for the screenshot request or the sharing request to an original content creator of the content specified as the copyright protection target. The notification may include chatroom information capable of identifying the chatroom, for example, an ID or a URL of the chatroom in which the input event is recognized.

In operation S1330, the marker 330 may add a mark that includes chatroom information to the content specified as the copyright protection target. For example, the marker 330 may create a QR code that includes information (e.g., an ID or a URL of the chatroom) capable of identifying the chatroom in which the input event is recognized, and may add the QR code to the content specified as the copyright protection target in response to the input event.

In operation S1340, once the notification is forwarded to the original content creator of the content specified as the copyright protection target, the function executer 340 may execute a function, for example, a screenshot function or a sharing function, corresponding to the input event recognized in operation S1310 for the content to which the mark is added. That is, in response to the input event for the chatroom, the function executer 340 may capture and store or share the content specified as the copyright protection target in a state in which the mark is added to the content.

Therefore, in response to recognizing an input event, for example, a screenshot request or a sharing request, corresponding to an instruction for calling a copyright protection function in the chatroom, the processor 212 may provide a notification to the original content creator having sent an original version of the content specified as the copyright protection target and also add, to the content, the mark that includes chatroom information and then perform a function corresponding to the input event using the content to which the mark is added.

FIG. 14 is a flowchart illustrating another example of a content protection method performed by an electronic device according to at least one example embodiment.

Referring to FIG. 14, in operation S1410, the event recognizer 310 may recognize a screenshot request or a sharing request as an input event for content included in a chatroom in the chatroom. That is, the event recognizer 310 may recognize the screenshot request or the sharing request that is an input event associated with content as an instruction for calling a copyright protection function in the chatroom.

In operation S1420, in response to recognizing the input event corresponding to the instruction for calling the copyright protection function in the chatroom, the notification forwarder 320 may forward, to an original content creator, a notification for content specified as a copyright protection target for a chatroom content protection. In the case of the screenshot request, content included in a screenshot range of the chatroom may be specified as the copyright protection target. In the case of the sharing request, content selected to share with another chatroom or another medium may be specified as the copyright protection target. Here, the notification forwarder 320 may forward the notification for the screenshot request or the sharing request to an original content creator of the content specified as the copyright protection target. The notification may include chatroom information capable of identifying the chatroom, for example, an ID or a URL of the chatroom in which the input event is recognized. In some example embodiments, the notification may include a callback URL for responding with an approval intent from the original content creator to allow the other user to use the content.

In operation S1430, the marker 330 may determine whether the original content creator approves use of the content specified as the copyright protection target through the notification. The marker 330 may receive an approval intent or a disapproval intent of the original content creator for the use of the content from the electronic device 120 of the original content creator through the notification forwarded to the original content creator.

In operation S1440, in response to receiving the approval intent from the electronic device 120 of the original content creator with respect to the content specified as the copyright protection target, the marker 330 may add, to the content, the mark that includes chatroom information. For example, the marker 330 may create a mark that includes information capable of identifying the chatroom in which the input event is recognized, for example, an ID or a URL of the chatroom, and may add the mark to the content specified as the copyright protection target in response to the input event.

In operation S1450, once the notification is forwarded to the original content creator of the content specified as the copyright protection target, the function executer 340 may execute a function, for example, a screenshot function or a sharing function, corresponding to the input event recognized in operation S1410 for the content to which the mark is added. That is, in response to the input event for the chatroom, the function executer 340 may capture and store or share the content specified as the copyright protection target in a state in which the mark is added to the content.

If the original content creator disapproves the use of the content in operation S1430, the processor 212 may process a screenshot or sharing of the corresponding content to be disallowed. For example, if the original content creator disapproves the use of the content, the processor 212 may determine that the screenshot or sharing of the content is impossible (or is not allowed) and may output a message that rejects the screenshot request or the sharing request.

Also, if the notification is forwarded to at least two original content creators, the processor 212 may add a mark to content of an original content creator that sends an approval intent and may process a screenshot or sharing to be disallowed for content of an original content creator that sends a disapproval intent. For example, as described above with reference to FIG. 12, if chat contents included in the screenshot range 1210 relates to messages of the user A and the user B, a notification may be forwarded to the user A and the user B. Here, if the user A approves use of content and the user B disapproves use of content, the processor 212 may execute screenshot or sharing by excluding the message of the user B and by adding a mark only to the message of the user A.

Therefore, in response to an input event, for example, a screenshot request or a sharing request, corresponding to an instruction for calling a copyright protection function in the chatroom, the processor 212 may provide a notification to an original content creator having sent an original version of the content specified as the copyright protection target and also add, only to the content of which use is approved by the original content creator, the mark that includes chatroom information and capture and store or share the content to which the mark is added through the notification.

Although the description is made based on an example of adding a mark to content in response to an input event corresponding to each of an upload request, a screenshot request, and a sharing request, the mark may be added to the content in an initial stage (e.g., an upload or screenshot stage), or in a final stage (e.g., a sharing stage) depending on some example embodiments. That is, the mark may be added to the content in the upload stage and then screenshot or sharing may be allowed only to the content to which the mark is added. In some example embodiments, the mark may be added to the content in the screenshot stage and then sharing may be allowed only to the content to which the mark is added. In some other example embodiments, the mark may be added to the content in the sharing stage for sharing the uploaded or screenshotted content such that the content may be shared in a state in which the mark is added.

According to example embodiments, it is possible to add a mark (e.g., a QR code and a watermark) including chatroom information to content to be uploaded, screenshotted, or shared in a chatroom for protecting contents in the chatroom, or to provide a notification for use of content to an original content creator having sent an original version of the content in response to a screenshot request or a sharing request for the content in the chatroom. The processor 212 may protect copyrights in the chatroom using the mark or the notification and may track the use of the content of which a copyright is to be protected through interaction with the server 150.

Although it is described that the content protection method is performed by the electronic device 110 in response to an instruction provided from an application (e.g., a messenger) installed on the electronic device 110, it is provided as an example only. According to some example embodiments, at least a portion of the content protection method may be performed on the side of the server 150 through interaction with the application (e.g., the messenger) installed on the electronic device 110.

For example, the processor 222 of the server 150 may include an event recognizer, a notification forwarder, a marker, a function executer, and a content manager such that the server 150 may perform at least a portion of the content protection method. Depending on example embodiments, the event recognizer, the notification forwarder, marker, the function executer, and the content manager may be selectively included in or excluded from the processor 222 of the server 150 and may be separated or merged for functional representation of the processor 222.

The event recognizer, the notification forwarder, the marker, the function executer, and the content manager included in the processor 222 of the server 150 perform the functionality identical or corresponding to the event recognizer 310, the notification forwarder 320, the marker 330, the function executer 340, and the content manager 350 of FIG. 3. Therefore, further description is omitted.

According to some example embodiments, it is possible to add a mark that includes chatroom information to content to be uploaded to a chatroom, and to provide an access to the chatroom that is a source of content using the mark added to the content. According to some example embodiments, in response to a screenshot request or a sharing request for content in a chatroom, it is possible to add a mark to the content and to store as a screenshot or share the content to which the mark is added. According to some example embodiments, in response to a screenshot request or a sharing requesting for content in a chatroom, it is possible to forward a notification to an original content creator and to execute screenshot or sharing according to approval of the original content creator for the content.
