Description

[0001] This application is a divisional application of the invention patent application with application number 2023114300848, application date October 31, 2023, entitled "A content sharing method based on an electronic paper display and related equipment thereto". Technical Field

[0002] This application relates to the field of communication technology, and more specifically, to a content sharing system based on an electronic paper display. Background Technology

[0003] Reading excellent books and watching excellent video content can improve residents' quality of life. Currently, the promotion of excellent books and videos relies mainly on official channels, which has limited effectiveness. Therefore, it is necessary to find a system that makes it convenient for the public to recommend and share excellent content. Summary of the Invention

[0004] The purpose of this application is to provide a content sharing system based on an electronic paper display, which can facilitate the public to recommend and share high-quality content information.

[0005] This application provides a content sharing system based on an electronic paper display, including a server, multiple public electronic paper displays distributed in a target area, and user terminals, wherein the user terminals are communicatively connected to the server. The user terminal is used to send a sharing request to the server; the sharing request includes information about the sharing recipient and information about the reason for sharing. When the server receives a sharing request from a user terminal, it extracts the sharing object information and sharing reason information from the sharing request information, determines whether the content of the sharing object contains inappropriate information based on the sharing object information, and generates link information and authorization information for the sharing object when the content of the sharing object does not contain inappropriate information. The authorization information is used to grant the user terminal the permission to publish the sharing object information, the link information, and the sharing reason information on the public electronic paper display, and sends the link information and authorization information to the user terminal so that the user terminal can publish the sharing object information, the link information, and the sharing reason information on the public electronic paper display. The user terminal is also used to publish the sharing object information, the link information, and the sharing reason information on the public electronic paper display using the authorization information.

[0006] Beneficial effects: The content sharing system based on electronic paper displays provided in this application allows the public to send a sharing request containing information about the object of sharing and the reason for sharing to the server using a user terminal. The server analyzes the information about the object of sharing and, after determining that the object does not contain inappropriate information, authorizes the user terminal to publish the information about the object of sharing, the reason for sharing, and the link information of the object of sharing on a public electronic paper display. This allows others to access the content of the object of sharing through the link information on the public electronic paper display, thereby facilitating the public to recommend and share high-quality content.

[0010] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0011] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0012] Please refer to Figure 1 , Figure 1 This application describes a content sharing method based on an electronic paper display, implemented through a content sharing system for electronic paper displays. Applied to a server, the method includes the following steps: A1. Upon receiving a sharing request from a user terminal, extract the sharing recipient information and the sharing reason information from the sharing request information; A2. Determine whether the content shared by the recipient contains inappropriate information based on the recipient's information; A3. When the content of the shared object does not contain inappropriate information, generate the link information and authorization information of the shared object; the authorization information is used to grant the user terminal the permission to publish the shared object information, link information and sharing reason information on the public electronic paper display; A4. Send the link information and authorization information to the user terminal so that the user terminal can publish the sharing object information, link information and sharing reason information on the public electronic paper display.

[0013] After the public sends a sharing request containing information about the object of the sharing and the reason for sharing to the server using a user terminal, the server analyzes the information about the object of the sharing. If it determines that the object of the sharing does not contain harmful information, it authorizes the user terminal to publish the information about the object of the sharing, the reason for sharing, and the link information of the object of the sharing on a public electronic paper display, so that others can access the content of the object of the sharing through the link information on the public electronic paper display; thus, it is convenient for the public to recommend and share good content information.

[0014] This content sharing method based on electronic paper displays can be applied to, for example... Figure 2 The server 100 of the content sharing system based on electronic paper display shown.

[0015] The shared object can be, but is not limited to, books, articles, videos, etc. The shared object information is the identification information of the shared object, such as book title, article title, video title, etc.

[0016] The sharing reason information is the reason why the user recommends the shared object, which may include the user's evaluation of the shared object, the insights or inspiration the user gained from the shared object, etc.

[0017] Users can input information about the recipient and the reason for sharing in their mobile devices via an app or mini-program. The user device will then generate a sharing request containing the recipient and reason for sharing and send it to the server.

[0018] Step A2 includes: obtaining the content of the sharing object based on the sharing object information, and performing inappropriate information detection on the content of the sharing object to determine whether it contains inappropriate information. This can be achieved by using at least one of the following methods: keyword detection, comparison with a list of inappropriate information recorded in an inappropriate content information database, or comparison with a list of good information recorded in a good content information database.

[0019] For example, in some embodiments, the step of detecting inappropriate information in the content of the shared object to determine whether it contains inappropriate information includes: Compare the information of the shared object with the directory of excellent information recorded in the excellent content information database to determine whether the information of the shared object is included in the directory of excellent information; If the information of the shared object is included in the directory of good information, then it is determined that the content of the shared object does not contain harmful information; If the information about the shared object is not included in the directory of good information, then the information about the shared object is compared with the directory of bad information recorded in the database of bad content to determine whether the information about the shared object is included in the directory of bad information. If the information of the shared object is included in the directory of harmful information, then the content of the shared object is determined to contain harmful information. If the information to be shared is not included in the list of harmful information, then keyword detection technology is used to detect whether the information to be shared contains harmful information (this is existing technology and will not be described in detail).

[0020] First, compare the content with the directories of good and bad information, and then perform keyword detection to determine whether bad information is included. Compared with direct keyword detection, this approach is more effective in avoiding misjudging good content as bad content and vice versa.

[0021] Among these features, the information of the sharing objects requested by users can be reviewed periodically to determine whether the corresponding sharing objects are good or bad content information, and then the good information directory and bad information directory can be updated.

[0022] In step A3, the link information of the shared object is used to retrieve the content of the shared object. This link information can be a QR code or a website. The public can scan the QR code with a mobile device to extract the corresponding content, or enter the website address into a browser to obtain the corresponding content. Compared with directly publishing the content of the shared object on a public electronic paper display, this method can significantly reduce the amount of data transmission and allows the public to conveniently view the content of the shared object using their own mobile devices. The public does not need to stay at the public electronic paper display to view the content, which is more conducive to the promotion of high-quality content.

[0023] When a user terminal obtains authorization information, it can transmit the authorization information, sharing object information, link information, and sharing reason information to a public electronic paper display via wireless communication (such as Bluetooth connection, WIFI connection, NFC connection, etc.). The public electronic paper display will then verify the validity of the authorization information and display the sharing object information, link information, and sharing reason information.

[0024] In some implementations, the authorization information is used to grant the user terminal the permission to publish and share information, link information, and sharing reason information on any N public electronic paper displays; N is a preset positive integer (which can be set according to actual needs).

[0025] Users only need to obtain authorization once to post information about the sharing recipient, the reason for sharing, and a link on any N public e-paper displays, making it easier for the public to recommend and share high-quality content. When N is greater than 1, when a user shares the same content on multiple different public e-paper displays, they do not need to fill in the sharing recipient and reason information each time, improving convenience. Furthermore, users do not need to send sharing requests to specific public e-paper displays; they can make sharing requests anytime, anywhere (without needing to be near the public e-paper display). After obtaining authorization, they can freely choose the public e-paper displays to post the information, further enhancing ease of use.

[0026] Furthermore, after step A1 and before step A2, the following steps are also included: A5. If authorization information for the same sharing object has been granted to the same user terminal within the first preset time period before the current time, then the sharing request is rejected; otherwise, steps A2-A4 are executed.

[0027] Some people may post and share information on a large number of public electronic paper displays in a short period of time for commercial or other malicious purposes. Here, the same user terminal is limited to one authorization for the same sharing object within a first preset time period (which can be set according to actual needs). Therefore, it is not possible to post and share information on a large number of public electronic paper displays in a short period of time, thereby preventing users from using public electronic paper displays for malicious recommendations (such as recommendations and sharing for commercial purposes).

[0028] In other implementations, the sharing request information includes identification information of the target public electronic paper display; the authorization information is used to grant the user terminal permission to publish sharing object information, link information and sharing reason information on the target public electronic paper display.

[0029] Therefore, once a user terminal is authorized, it can only publish information on the requested target public electronic paper display, so as to more effectively prevent users from using public electronic paper displays for malicious recommendations.

[0030] For example, the identification information of a public electronic paper display may include, but is not limited to, serial number, MAC code, ID number, etc. This identification information may be contained in a QR code, which may be displayed or printed on the public electronic paper display. The user terminal triggers a sharing request operation procedure by scanning the QR code of the target public electronic paper display. In response to the sharing request operation procedure, the user inputs information about the object to be shared and information about the reason for sharing. The user terminal generates a sharing request information based on the input information about the object to be shared and information about the reason for sharing, as well as the identification information obtained from the QR code, and sends it to the server.

[0031] Furthermore, after step A1 and before step A2, the following steps are also included: A6. Based on the user terminal's sharing history information of the sharing object, determine whether the current sharing request is an abnormal request. If so, reject the sharing request; otherwise, proceed with steps A2-A4. The sharing history information includes the number of times and the sharing location of information for the same sharing object within a second preset time period (which can be set according to actual needs) before the current time from the same user terminal; the sharing location is the location of the corresponding target public electronic paper display.

[0032] Specifically, refusing to share a request may include not generating authorization information, or sending a notification message to the user terminal indicating that authorization is not granted.

[0033] The location of the target public electronic paper display can be obtained by querying the local database (which records the identification information and corresponding location of each public electronic paper display) based on the identification information of the target public electronic paper display, or it can be obtained by the user terminal through the positioning module when sending the sharing request information and sent to the server.

[0034] Some people may post and share information on a large number of public e-paper displays in a short period of time for commercial or other malicious purposes. Here, we first use the sharing history information of the user terminal for the same sharing object to determine whether the current sharing request is an abnormal request. Only when the current sharing request is not an abnormal request will sharing be allowed, thereby preventing users from using public e-paper displays to make malicious recommendations (such as recommendations and sharing for commercial purposes).

[0035] Preferably, the step of determining whether the current sharing request is an abnormal request based on the user terminal's sharing history of information about the sharing object includes: If the number of times a user terminal shares the same information about the same object exceeds the first preset threshold (which can be set according to actual needs) within the second preset time period before the current time, then the current sharing request is determined to be an abnormal request. If the number of times a user terminal shares the same information about the same shared object within the second preset time period before the current time does not exceed the first preset threshold, then the sharing request is determined as an abnormal request based on the sharing location of the user terminal sharing the same information about the same shared object within the second preset time period before the current time.

[0036] Generally, when users make normal sharing recommendations, they usually only post information on public electronic paper displays in places they frequently visit. Moreover, most people's daily routines involve relatively fixed areas, rarely spreading across various preset zones. Conversely, if a user posts information for commercial or other malicious purposes, they will post it over a wider area, resulting in a wide distribution of sharing locations. Based on this characteristic, in some embodiments, the step of determining whether a sharing request is abnormal based on the sharing location of the same shared object information within a second preset time period before the current moment includes: Each sharing location is determined by a preset partition, which is called the publishing area. The preset partition is a sub-region obtained by dividing the target area (such as a community, street, city, or other administrative area) for deploying public electronic paper displays in advance. Calculate the total area of ​​all publishing areas (the area of ​​the same publishing area is only added once); If the total area of ​​all published areas accounts for more than the percentage of the total area of ​​the target area, the sharing request is determined to be an abnormal request. If the proportion of the total area of ​​all publishing areas in the total area of ​​the target area does not exceed the preset first proportion threshold and is greater than the preset second proportion threshold (the second proportion threshold is smaller than the first proportion threshold, and can be set according to actual needs), then the sharing locations are clustered to obtain the locations of multiple cluster centers. The average distance between each pair of these cluster centers is calculated. If the average value exceeds the preset distance threshold (which can be set according to actual needs), then the sharing request is determined to be an abnormal request. If the average value does not exceed the preset distance threshold, then the sharing request is determined to be not an abnormal request. If the total area of ​​all published areas accounts for no more than the percentage of the total area of ​​the target area, then the sharing request is determined to be not an abnormal request.

[0037] As can be seen from the above, this content sharing method based on electronic paper displays, upon receiving a sharing request from a user terminal, extracts the sharing object information and sharing reason information from the sharing request information; determines whether the content of the sharing object contains inappropriate information based on the sharing object information; if the content of the sharing object does not contain inappropriate information, generates link information and authorization information for the sharing object; the authorization information is used to grant the user terminal the permission to publish the sharing object information, link information, and sharing reason information on a public electronic paper display; and sends the link information and authorization information to the user terminal so that the user terminal can publish the sharing object information, link information, and sharing reason information on a public electronic paper display; thereby facilitating the public to recommend and share high-quality content information.

[0038] refer to Figure 2 The present application provides a content sharing system based on electronic paper displays, including a server 100, multiple public electronic paper displays 200 distributed in a target area (such as a community, street, urban area, or other administrative area), and user terminals 300, wherein the user terminals 300 are communicatively connected to the server 100. User terminal 300 is used to send sharing request information to server 100; the sharing request information includes sharing object information and sharing reason information; When server 100 receives a sharing request from user terminal 300, it extracts the sharing object information and sharing reason information from the sharing request information. Based on the sharing object information, it determines whether the content of the sharing object contains inappropriate information. If the content of the sharing object does not contain inappropriate information, it generates link information and authorization information for the sharing object. The authorization information is used to grant user terminal 300 the permission to publish the sharing object information, link information, and sharing reason information on the public electronic paper display 200. The link information and authorization information are then sent to user terminal 300 so that user terminal 300 can publish the sharing object information, link information, and sharing reason information on the public electronic paper display 200 (for details, refer to the previous section on content sharing methods based on electronic paper displays). User terminal 300 is also used to publish information about the sharing object, link information, and reason for sharing on public electronic paper display 200 using authorization information.

[0039] After the public sends a sharing request containing information about the object of sharing and the reason for sharing to the server 100 via user terminal 300, the server 100 analyzes the information about the object of sharing. If it determines that the object of sharing does not contain harmful information, it authorizes the user terminal 300 to publish the information about the object of sharing, the reason for sharing, and the link information of the object of sharing on the public electronic paper display 200, so that others can access the content of the object of sharing through the link information on the public electronic paper display 200. This makes it convenient for the public to recommend and share good content information.

[0040] Preferably, when the user terminal 300 publishes the sharing object information, link information and sharing reason information on the public electronic paper display using the authorization information, it transmits the authorization information, sharing object information, link information and sharing reason information to the public electronic paper display 200 via NFC transmission. The public electronic paper display 200 is used to verify the validity of the authorization information when it receives authorization information, sharing object information, link information, and sharing reason information, and to display the sharing object information, link information, and sharing reason information when the authorization information is valid.

[0041] The user terminal 300 may transmit authorization information, sharing object information, link information and sharing reason information to the public electronic paper display 200 via NFC transmission, or via wireless transmission methods such as Bluetooth and WIFI.

[0042] The public electronic paper display 200 can also communicate with the server 100.

[0043] Furthermore, the public electronic paper display 200 can display sharing object information, link information, and sharing reason information corresponding to multiple sharing objects. At this time, the display duration of each sharing object can be adjusted according to the recommendation value of each sharing object. The higher the recommendation value, the longer the display duration. The recommendation value is sent from the server 100 to the public electronic paper display 200. Specifically, the server 100 obtains the recommendation value of each sharing object according to preset scoring rules (such as calculating the recommendation value based on parameters such as the number of views, the proportion of positive reviews, and the proportion of negative reviews, but not limited to these) or through manual scoring, and sends it to the corresponding public electronic paper display 200.

[0044] In some implementations, the authorization information is used to grant the user terminal the permission to publish and share information, link information, and sharing reason information on any N public electronic paper displays; N is a preset positive integer (which can be set according to actual needs).

[0045] Furthermore, after extracting the sharing object information and sharing reason information from the sharing request information, server 100 executes: If authorization for sharing information with the same target was granted to the same user terminal within the first preset time period prior to the current moment, the sharing request will be rejected; otherwise, subsequent steps will be executed.

[0046] In other implementations, the sharing request information includes identification information of the target public electronic paper display; the authorization information is used to grant the user terminal 300 permission to publish sharing object information, link information and sharing reason information on the target public electronic paper display.

[0047] For example, the identification information of the public electronic paper display 200 may be, but is not limited to, number information, MAC code, ID number, etc., and this identification information may be contained in a QR code, which may be displayed or printed on the public electronic paper display 200; the user terminal 300 triggers a sharing request operation procedure by scanning the QR code of the target public electronic paper display, and the user responds to the sharing request operation procedure by inputting the sharing object information and the sharing reason information, and the user terminal 300 generates sharing request information based on the input sharing object information, sharing reason information and the identification information obtained from the QR code and sends it to the server 100.

[0048] Furthermore, after extracting the sharing object information and sharing reason information from the sharing request information, server 100 executes: Based on the sharing history information of the user terminal 300 for the sharing object information, determine whether the current sharing request is an abnormal request. If it is, reject the sharing request; otherwise, proceed with the subsequent steps. The sharing history information includes the number of times and the sharing location of the same user terminal 300 sharing information for the same sharing object within a second preset time period (which can be set according to actual needs) before the current time; the sharing location is the location of the corresponding target public electronic paper display.

[0049] Specifically, refusing to share a request may include not generating authorization information, or sending a notification message to the user terminal 300 indicating that authorization is not granted.

[0050] The location of the target public electronic paper display can be obtained by querying the local database (which records the identification information and corresponding location of each public electronic paper display) based on the identification information of the target public electronic paper display, or it can be obtained by the user terminal 300 through the positioning module when sending the sharing request information and sent to the server 100.

[0051] Preferably, the step of determining whether the current sharing request is an abnormal request based on the sharing history information of the sharing object information of the user terminal 300 includes: If the number of times the user terminal 300 shares the same information about the same sharing object exceeds the first preset threshold (which can be set according to actual needs) within the second preset time period before the current time, then the current sharing request is determined to be an abnormal request. If the number of times the user terminal 300 shares the same information about the same shared object within the second preset time period before the current time does not exceed the first preset threshold, then the sharing position of the user terminal 300 in sharing the same information about the same shared object within the second preset time period before the current time will be used to determine whether the current sharing request is an abnormal request.

[0052] In some embodiments, the step of determining whether the current sharing request is an abnormal request based on the sharing location of the user terminal 300 sharing the same sharing object information within a second preset time period before the current time includes: Each sharing location is determined by a preset partition, which is called the publishing area. The preset partition is a sub-region obtained by dividing the target area (such as a community, street, city, or other administrative area) for deploying public electronic paper displays in advance. Calculate the total area of ​​all publishing areas (the area of ​​the same publishing area is only added once); If the total area of ​​all published areas accounts for more than the percentage of the total area of ​​the target area, the sharing request is determined to be an abnormal request. If the proportion of the total area of ​​all publishing areas in the total area of ​​the target area does not exceed the preset first proportion threshold and is greater than the preset second proportion threshold (the second proportion threshold is smaller than the first proportion threshold, and can be set according to actual needs), then the sharing locations are clustered to obtain the locations of multiple cluster centers. The average distance between each pair of these cluster centers is calculated. If the average value exceeds the preset distance threshold (which can be set according to actual needs), then the sharing request is determined to be an abnormal request. If the average value does not exceed the preset distance threshold, then the sharing request is determined to be not an abnormal request. If the total area of ​​all published areas accounts for no more than the percentage of the total area of ​​the target area, then the sharing request is determined to be not an abnormal request.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
