The present invention relates to the field of image communication technology between computer terminals, and in particular, to a computer image communication method, device and image communication equipment.
Background
With the development of internet technology, instant messaging tools have become an indispensable tool in daily life, work and study of people. The instant communication tool is installed in the computer intelligent terminal and transmits signals through a wired network or a wireless network. When a user sends an image (such as a picture or a video file) through the instant messaging tool, the sending end sends an image signal to the service end, and the service end sends the image signal to the receiving end.
In the group chat of the instant messaging tool, the sending end sends a signal belonging to a point-to-multipoint transmission signal, so that the privacy of the sent file cannot be ensured, and if the point-to-point transmission signal is required, the sending end can only send the signal independently. For example, in group chat, an image sent by one sending end is received by multiple receiving ends at the same time, if a user wants to receive only part of the receiving ends, only single-point-to-single-point sending can be performed on the receiving ends separately, or group chat is re-created, and in either way, the user needs to perform cumbersome operation, so that the user has poor experience on an instant messaging tool.

Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
In instant messaging applications, users can create a group chat, when users send pictures or video files on the group chat interface, all users in the group can view the pictures or video files on the group chat interface, and if the pictures or video files which the users want to send are only viewed by certain specific users (other users in the group cannot view), the pictures or video files can only be sent to the users individually or the group chat can be re-created.
Taking on-line teaching as an example, the on-line teaching takes an intelligent terminal as a carrier, and the homework of students is also sent to teachers through the intelligent terminal. If students need to be grouped in the teaching process and learning contents of different groups are different, a teacher needs to create a group chat for each group in the instant messaging application or send the learning contents of each group to a class group, the former is complex in operation, and the latter is easy to cause confusion. In addition, the homework of students is usually required to be sent to the teacher in the form of pictures, if the homework sent by the students only needs to be seen by the teacher, but not by other students, the homework can only be sent to the teacher independently, and in the homework received by the teacher, part of the homework is from a class group, part of the homework is from friends, and the homework completion condition is difficult to count.
Aiming at the problems that the prior instant messaging application cannot enable users to send pictures or video files to certain specific users in group chat, so that the operation is complicated and the user experience is poor in certain scenes, the invention provides a computer image communication method which allows the users to send the pictures or video files on a group chat interface of the instant messaging application, and designates certain users to view, wherein the users which are not designated cannot view the pictures or video files.
Fig. 1 shows a schematic diagram of a computer image communication system 100 according to one embodiment of the invention. As shown in fig. 1, the system 100 includes a first service end 110, a second service end 120, and a plurality of terminals 130.
In the embodiment of the present invention, the computer refers to a broad-sense computer, including a narrow-sense computer and intelligent terminals such as a mobile phone and a tablet.
The first service end 110 is a message service end, and is used for storing a message sent by a user. Taking WeChat as an example, the first server 110 is an IM server, which is also called WeChat communication server. The second server 120 is a file server, and is configured to store files sent by a user, including pictures, videos, voices, and the like. When one terminal 130 (hereinafter referred to as a transmitting end) transmits a file, such as a picture, to another terminal (hereinafter referred to as a receiving end), the picture is first uploaded to the second server 120, then the second server 120 returns the storage address of the picture at the second server 120 to the transmitting end, the transmitting end encapsulates the storage address and transmits the encapsulated storage address to the receiving end through the first server 110, after the receiving end receives a data packet, the picture is downloaded to the second server 120 according to the address carried by the data packet, and after the downloading is completed, a user can view the picture at the receiving end.
In an embodiment of the present invention, the second server 120 is adapted to perform a computer image communication method. The computer image communication method 300 of the present invention will be described in detail below.
In one embodiment, the second server 120 of the present invention may be implemented as an image communication device, so that the computer image communication method of the present invention may be performed in the image communication device.
Fig. 2 shows a block diagram of an image communication apparatus 200 according to an embodiment of the present invention. As shown in fig. 2, the image communication apparatus 200 includes a hard disk 210, a processor 220, a memory 230, and a network communication module 240, and communication is performed between the hard disk 210, the processor 220, the memory 230, and the network communication module 240 through a bus.
The hard disk 210 stores therein an instant messaging application 211 and program instructions 212 for executing a computer image communication method. These program instructions may instruct the processor 204 to perform the computer image communication method 300 of the present invention so that the image communication apparatus 200 performs the computer image communication method 300 of the present invention.
A computer image communication method 300 of an embodiment of the present invention provides its functionality in the form of a plug-in.
A computer image communication method 300 according to an embodiment of the present invention includes: receiving a data packet which is simultaneously transmitted to a plurality of second terminals by a first terminal, and extracting original image data in the data packet; copying the original image data to obtain two identical original image data; processing one original image data to obtain processed image data, so that the original image data cannot be displayed on a second terminal which receives the processed image data; and sending another original image data to the appointed second terminal according to the information of the appointed second terminal carried in the data packet, and simultaneously sending the processed image data to the second terminals which are not appointed in the plurality of second terminals.
Fig. 3 shows a flow chart of a computer image communication method 300 according to one embodiment of the invention. The method 300 is performed in an image communication device, such as the image communication device 200 described previously. As shown in fig. 3, the method 300 begins at S310.
In S310, a data packet transmitted by a first terminal to a plurality of second terminals at the same time is received, and original image data and information of the designated second terminals in the data packet are extracted.
In this embodiment, the first terminal is a transmitting end, the second terminal is a receiving end, a user corresponding to the first terminal is referred to as a first user, a user corresponding to the second terminal is referred to as a second user, and the first user and the second user refer to users in the same group chat of the instant messaging application.
The first user sends the image in the group chat interface through the first terminal, and the image in the embodiment includes a picture file and a video file, and the first user sends the image file or the video file.
Before sending an image, the first user needs to specify a user in the group chat who is allowed to view the image, or to specify a user in the group chat who is not allowed to view the image. Assuming that the first user designates a user allowed to view the image in the group chat, the first terminal encapsulates the image transmitted by the first user and the designated user ID into a data packet, and uploads the data packet to a server (e.g., the aforementioned second server 120).
The server (e.g., the aforementioned second server 120) receives the data packet from the first terminal and extracts the specified user ID and image data, also referred to herein as raw image data, from the data packet.
Next, in S320, the original image data is copied to obtain two identical copies of the original image data. Here, two identical pieces of original image data are referred to as first original image data and second original image data, respectively.
Next, in S330, one of the original image data is processed to obtain processed image data, so that the original image data cannot be displayed on the second terminal that received the processed image data.
When the image is a picture file, the processing of the second original image data may be modifying pixel values of the second original image data to obtain the second image data. The pixel values may be changed randomly, or all the pixel values may be changed to a certain fixed value, where the fixed value may be a preset fixed value, or may be a fixed value selected randomly, or may be changed in other manners, and the embodiment of the present invention does not limit the manner of changing the pixel values. The preferred mode is to change all pixel values of the image to a preset fixed value, for example, change the image to a pure gray image, and the mode has simple data processing process and low consumption of computational resources, and the user cannot judge the content of the original image according to the changed image.
When the image is a video file, the processing of the second original image data may be to use any one frame image in the video file instead of the second original image data, and use this frame image instead of the second original image data as the second image data. Instead of the second original image data, a solid-color picture may be used, and this solid-color picture may be used as the second image data.
Next, in S340, another original image data is transmitted to the designated second terminal according to the information of the designated second terminal carried in the data packet, and the processed image data is transmitted to the second terminal which is not designated among the plurality of second terminals.
Through S330, the first original image data is unchanged, and the second original image data has been changed to the second image data. In S340, the designated second terminal is a terminal corresponding to the user designated by the first user to allow viewing of the image, and in fact, the ID of the user is designated here. And the server determines the ID of the user capable of viewing the image and the ID of the user incapable of viewing the image in the group chat according to the information of the designated second terminal carried in the data packet, then sends the first original image data to the user capable of viewing the image, and simultaneously sends the second image data to the user incapable of viewing the image. When each user in the group chat views the chat interface at the terminal, the first user and the designated user capable of viewing the image can view the first original image data at the group chat interface, while other users in the group chat view the image data (e.g. a solid-color picture) completely different from the first original image data.
Assuming that a user a logs in an instant messaging application on a terminal and sends a video in a group chat, wherein the group chat has A, B, C, D, E total five members, when the user a sends the video, designating a user B and a user D as users capable of viewing the video, the terminal compresses the video sent by the user a, encapsulates the compressed video file, the ID of the user B, the ID of the user D and the ID of the group chat into a data packet, and then uploads the data packet to a server. The server extracts the video file, the ID of the group chat, and the IDs of the user B and the user D from the data packet. Then, the server may temporarily split the group chat into one group and two groups (related information of the temporarily split group is stored in a cache of the server, and after the subsequent image file is sent, the cache is cleared), where a group includes three members of user a, user B, and user D, and a second group includes two members of user C and user E, and copies the video file, and then processes one of the video files. In practice, the copying process may be omitted for video files, but instead a solid-color picture may be used directly as the second image. Then, the server sends the original video file to a group and sends the solid-color picture to two groups, so that the user A, the user B and the user D can view the complete video file in the group chat interface, and the user C and the user E can only see one solid-color picture.
When the server sends a file to the receiving end, the second server may refer to the system 100, after receiving the file by the second server, store the first original image data to the second server, after processing the second original image data, store the second image data to the second server, then return the storage address of the first original image data and the storage address of the second image to the first user, the first client encapsulates the storage address of the first original image data and the storage address of the second image respectively, and sends the encapsulated storage address of the first original image data to the first server, the first server sends the storage address of the first original image data to a group in a group chat, sends the storage address of the second image to a second group in the group chat, the user in the group views the file and downloads the downloaded file into the second server according to the corresponding address, the downloaded file is the original video file (i.e. the video file sent by the first user), and the address obtained by the user in the second group is the address of the second image, and the downloaded file is the second image (i.e. a pure color picture).
When the user finishes transmitting the image, if the designated user needs to be changed, the user can select the transmitted image on the group chat interface and request retransmission, and when the retransmission is requested, the user capable of viewing the image needs to be designated again. When the server receives the retransmission request, it needs to determine the information of the designated second terminal carried by the retransmission request, that is, the ID of the designated user, and then compare the ID of the designated user carried by the retransmission request with the ID of the designated user carried by the data packet transmitted for the first time (hereinafter referred to as the original designated user), where the comparison result may have the following cases:
(1) The users designated in the resending request contain the original designated users, and new designated users are added;
(2) The user specified in the resend request is a part of the originally specified users;
(3) The user users specified in the resend request include a part of the originally specified users, and new specified users are added.
In the case of (1), the server may retransmit the image to the new designated user in the group chat.
For the case (2), it is necessary to withdraw the image received by some of the originally designated users, for example, user B and user D, and the user designated in the retransmission request is user B, and then it is necessary to withdraw the image received by user D. It should be noted that, the premise of withdrawal is that the user does not view the image, if a certain user has viewed the image on the terminal, it means that the image has been downloaded locally, and at this time, withdrawal cannot be performed;
for case (3), the image received by the corresponding user is withdrawn, and at the same time, the image is retransmitted to the corresponding user. For example, the originally designated users are user B and user D, and the users designated in the retransmission request are user B and user C, so that the server needs to withdraw the image received by user D and send the image to user C on the premise that user D does not view the image.
The method 300 of the embodiment of the invention allows the user to set the users which are allowed to view the image and are not allowed to view the image in the group chat, the user does not need to send the image to other users separately or re-establish the group, and the user is allowed to resend, so that the privacy of the file can be ensured, and complicated operation can not be brought to the user.
Based on the concepts of method 300, the files in method 300 may also be expanded such that method 300 may also be adapted for transmission of other files (e.g., documents or audio files, etc.) or text messages.
