Description

Streaming conference device and audio and video data storage method thereof

The present disclosure relates to a streaming conferencing device and a method for storing audio and video data therein, and more particularly to a streaming conferencing device and a method for storing audio and video data therein that are capable of processing and storing digital audio and video data on a cloud platform.

With the rapid development of our modern world, today's work models increasingly include a high volume of online meetings, leading to a constant need for meeting recording. Furthermore, after a meeting concludes, the digital video data is stored on the conference system host. If a user needs to access the digital video data, the conference system host generates a digital video recording file for viewing or downloading.

However, conference digital image data files are large, easily occupying a large amount of disk space on the conference system host. Furthermore, the storage and processing of digital image data on the conference system host can easily consume the performance of the conference system host, thereby placing a burden on the conference system host. Furthermore, the digital image data generated by the conference system host is not encrypted, which can easily lead to the leakage of sensitive data. Furthermore, because the digital image data of the conference is stored on the conference system host, the conference system host is at risk of being infiltrated. Therefore, it is necessary to provide a streaming conferencing device and its audio and video data storage method to avoid the above-mentioned technical problems.

One aspect of the present disclosure discloses a method for storing audio and video data for a streaming conferencing device, comprising: receiving digital audio and video data from a conference system host via a conversion server to confirm whether the digital audio and video data contains audio data, image data, desktop sharing data, and timestamp data, wherein the conversion server is independent of the conference system host; if the digital audio and video data contains audio data, image data, desktop sharing data, and timestamp data, synthesizing the digital audio and video data into video file data via the conversion server; encrypting the video file data to generate encrypted video file data via the conversion server; and transmitting the encrypted video file data to a storage module via the conversion server, wherein the storage module is independent of the conference system host.

Another aspect of the present disclosure discloses a streaming conferencing device. The streaming conferencing device includes a conversion server and a video file transmission module. The conversion server includes an image confirmation module, an image synthesis module, and a video file encryption module. The image confirmation module is used to receive digital audio and video data from a conference system host to confirm whether the digital audio and video data has audio data, image data, desktop sharing data, and timestamp data, wherein the conversion server is independent of the conference system host. The image synthesis module is coupled to the image confirmation module and is used to synthesize the digital audio and video data from the image confirmation module into video file data. The video file encryption module is coupled to the image synthesis module and is used to encrypt the video file data from the image synthesis module to generate encrypted video file data. The video file transmission module is used to transmit encrypted video file data to the storage module, which is independent of the conference system host.

Therefore, through the streaming conference device and its audio and video data storage method disclosed herein, the digital audio and video data of the conference system host is transferred to the streaming conference device's conversion server for audio and video processing and encryption. The processed encrypted video file data can be transmitted to the storage module for storage through the conversion server. The encrypted video file data stored in the storage module can be managed through retention time data to reduce the disk space occupied by digital audio and video data on the conference system host, reduce the system burden of the conference system host, reduce the burden on the administrator of the conference system host, and improve the security of the conference system host and the storage security of sensitive data.

It should be noted that the above explanation and subsequent detailed description are provided to illustrate the present invention in the form of embodiments and to assist in the interpretation and understanding of the claimed invention.

The following disclosure provides numerous different embodiments or examples for implementing various features of this disclosure. Components and configurations from specific examples are used in the following discussion to simplify the disclosure. Any examples discussed are for illustrative purposes only and are not intended to limit the scope or meaning of this disclosure or its examples in any way. Where appropriate, identical reference numbers are used throughout the drawings and accompanying text to represent identical or similar elements.

Please refer to FIG. 1 , which illustrates a functional block diagram of a streaming conferencing device 100, a conferencing system 200, and a storage system 300 according to an embodiment of the present disclosure. As shown in FIG. 1 , the streaming conferencing device 100 is communicatively connected between the conferencing system 200 and the storage system 300.

In some embodiments, conferencing system 200 is a server for conducting online meetings. User devices can log in to conferencing system 200 and execute corresponding online conferencing applications (such as Skype, Google Meeting, WebEx, etc.). After the online meeting ends, the digital audio and video data of the meeting is typically stored on the conferencing system host 220 of conferencing system 200. However, the digital audio and video data files of the meeting are large, which may occupy a large amount of disk space on the conferencing system host 220, easily consume the performance of the conferencing system host 220, and cause a burden on the conferencing system host 220. There is even the risk of the conferencing system host 220 being infiltrated and sensitive data being leaked. Therefore, the streaming conferencing device 100 proposes a method for processing digital audio and video data, so that the digital audio and video data of the conferencing system host 220 is stored in a storage system 300 outside the conferencing system host 220 after video processing and encryption. This reduces the disk space occupied by the digital audio and video data on the conferencing system host 220, reduces the system burden on the conferencing system host 220, improves the security of the conferencing system host 220 and the storage security of sensitive data, and reduces the burden on the administrator of the conferencing system host 220.

For ease of explanation, the following sections primarily focus on the streaming conferencing device 100. In the embodiment shown in FIG. 1 , the streaming conferencing device 100 includes a conversion server 120 , which includes an image verification module 122 , an image synthesis module 124 , and a video file encryption module 126 . In one embodiment, the image verification module 122 , the image synthesis module 124 , and the video file encryption module 126 can each be independently configured.

In one embodiment, the conversion server 120 may include but is not limited to a system host on a cloud platform (e.g., Google Cloud Platform (GCP) or other similar cloud computing platforms) or any network server with image storage and processing capabilities, the image confirmation module 122 may include but is not limited to a medium attachment unit (MAU) or any transceiver with image receiving capabilities, the image synthesis module 124 may include but is not limited to a central processing unit (CPU) or any processor with image synthesis capabilities, and the video file encryption module 126 may include but is not limited to an encryption algorithm module with image encryption capabilities (e.g., an AES 256 algorithm module or other similar encryption algorithm modules), but the present disclosure is not limited to this.

For technical details regarding the functions and operations of the conversion server 120 and its image verification module 122 , image synthesis module 124 , and video file encryption module 126 of the streaming conferencing device 100 , please refer to the following description.

The image verification module 122 is used to receive digital video data V1 from the conference system host 220 of the conference system 200 and verify whether the digital video data V1 contains audio data V11, image data V12, desktop sharing data V13, and timestamp data V14. Specifically, the conference system host 220 sets the storage path of the digital video data V1 to the conversion server 120 (i.e., the image verification module 122), so that the image verification module 122 can receive the digital video data V1 through the image transmission module 240 of the conference system 200 and verify whether the digital video data V1 contains audio data V11, image data V12, desktop sharing data V13, and timestamp data V14. In one embodiment, the conversion server 120 is independent of the conference system host 220. In one embodiment, the conference system host 220 is located on a cloud platform. In one embodiment, the audio data V11 may include, but is not limited to, audio source data generated by a microphone (not shown) of the conference system host 220. The image data V12 may include, but is not limited to, user image data generated by a webcam (not shown) of the conference system host 220. The desktop sharing data V13 may include, but is not limited to, desktop image data generated by a desktop sharing module (not shown) of the conference system host 220. However, the present disclosure is not limited thereto. In one embodiment, timestamp data V14 may include, but is not limited to, multiple timestamps generated based on audio data V11, image data V12, and desktop sharing data V13. For example, timestamp data V14 may include a timestamp when a conference participant turns on a microphone (not shown) on conference system host 220 to speak, a timestamp when a conference participant turns on a webcam (not shown) on conference system host 220 to take a photo, and a timestamp when a conference participant turns on a desktop sharing module (not shown) on conference system host 220, but the present disclosure is not limited thereto. In one embodiment, image transmission module 240 may include, but is not limited to, a MAU unit or any transceiver with image transmission capabilities, but the present disclosure is not limited thereto.

The image synthesis module 124 is coupled to the image verification module 122 and is used to synthesize the digital audio and video data V1 from the image verification module 122 into the video file data V2. For example, the image synthesis module 124 integrates the audio data V11, image data V12, desktop sharing data V13 and time stamp data V14 of the digital audio and video data V1 to generate the video file data V2.

The video file encryption module 126 is coupled to the image synthesis module 124 and is configured to encrypt the video file data V2 from the image synthesis module 124 according to an encryption algorithm (e.g., the AES 256 algorithm) to generate encrypted video file data V3. In one embodiment, the video file encryption module 126 encrypts the video file data V2 according to the DES algorithm or any other image encryption algorithm to generate encrypted video file data V3.

In one embodiment, the streaming conferencing device 100 further includes a video file transmission module 140. The video file transmission module 140 is used to transmit the encrypted video file data V3 from the conversion server 120 to the storage module 340 of the storage system 300. Specifically, the conversion server 120 uses a mounting tool to mount the storage module 340, allowing the video file encryption module 126 of the conversion server 120 to transmit the encrypted video file data V3 to the storage module 340 via the video file transmission module 140. In one embodiment, the video file transmission module 140 may include, but is not limited to, a MAU unit or any transceiver with image transmission capabilities. The mounting tool may include, but is not limited to, the Gcsfuse tool, but the present disclosure is not limited thereto. In one embodiment, the storage module 340 is independent of the conference system host 220 and may include but is not limited to a cloud storage space (Google Cloud Storage, GCS) or any database with data storage.

In one embodiment, the video file transmission module 140 further generates a decryption key D1 based on the encrypted video file data V3 transmitted from the conversion server 120, and transmits the encrypted video file data V3 and the decryption key D1 to the user interface module 320 of the storage system 300. The user interface module 320 then records the decryption key D1 and transmits the encrypted video file data V3 to the storage module 340. Therefore, a user (e.g., user 500 in FIG. 3 ) can obtain the decryption key D1 through the user interface module 320 and use the decryption key D1 to decrypt the encrypted video file data V3 in the storage module 340 and obtain the video data content.

In one embodiment, the storage module 340 receives retention time data L1 and manages the encrypted video file data V3 according to the retention time data L1. The retention time data L1 defines the retention period of the encrypted video file data V3. For example, if the retention time data L1 defines the retention period of the encrypted video file data V3 as 6 months, the encrypted video file data V3 stored in the storage module 340 will be stored for 6 months and will be automatically deleted after 6 months.

In one embodiment, storage module 340 obtains retention time data L1 from a user (e.g., user 500 in FIG. 3 ) to manage stored encrypted video file data V3. For example, the user logs in through a login module (not shown) and inputs the retention time data L1 to storage module 340, causing storage module 340 to manage stored encrypted video file data V3 based on the received retention time data L1.

Therefore, through the streaming conferencing device 100 of Figure 1, the digital audio and video data V1 of the conferencing system host 220 can be transferred to the conversion server 120 of the streaming conferencing device 100 for audio and video processing and encryption. The processed encrypted video file data V3 can be transmitted to the storage module 340 for storage through the conversion server 120. The encrypted video file data V3 stored in the storage module 340 can be managed through the retention time data L1 to reduce the disk space occupied by the digital audio and video data V1 on the conferencing system host 220, reduce the system burden of the conferencing system host 220, reduce the burden on the administrator of the conferencing system host 220, and improve the security of the conferencing system host 220 and the storage security of sensitive data. Please also refer to FIG. 2 , which shows a flow chart of a method 400 for storing video data in the streaming conference device 100 of FIG. The method 400 for storing video data in FIG. 2 can be executed by the conversion server 120 of the streaming conference device 100 .

As shown in FIG2 , step S20 is executed, and the conversion server 120 receives the digital video data V1 and determines whether the digital video data V1 contains audio data V11, image data V12, desktop sharing data V13, and timestamp data V14. Specifically, in step S20, the conference system host 220 sets the storage path of the digital video data V1 to the conversion server 120. The conversion server 120 receives the digital video data V1 through the image verification module 122 and determines whether the digital video data V1 contains audio data V11, image data V12, desktop sharing data V13, and timestamp data V14. If so, step S22 is executed; if not, the video data storage method 400 ends.

If the digital video data V1 includes audio data V11, image data V12, desktop sharing data V13, and time stamp data V14, step S22 is executed, and the conversion server 120 synthesizes the digital video data V1 into video file data V2.

Next, step S24 is executed, where the conversion server 120 encrypts the video file data V2 to generate encrypted video file data V3. Specifically, in step S24, the conversion server 120 encrypts the video file data V2 according to an encryption algorithm to generate encrypted video file data V3.

Next, step S26 is executed, and the conversion server 120 transmits the encrypted video file data V3 to the storage module 340. Specifically, in step S26, the conversion server 120 uses a mounting tool to mount the storage module 340 to transmit the encrypted video file data V3 to the storage module 340 via the video file transmission module 140.

In one embodiment, during step S26, the video file transmission module 140 also generates a decryption key D1 based on the encrypted video file data V3 transmitted from the conversion server 120, and transmits the encrypted video file data V3 and the decryption key D1 to the user interface module 320, so that the user interface module 320 records the decryption key D1 and transmits the encrypted video file data V3 to the storage module 340.

In one embodiment, the audio and video data storage method 400 further includes step S28.

After step S26, step S28 is executed, where the storage module 340 receives the retention time data L1 and manages the encrypted video file data V3 according to the retention time data L1. For example, in step S28, a user (e.g., user 500 in FIG. 3 ) can log in through a login module (not shown) and input the retention time data L1 to the storage module 340, causing the storage module 340 to manage the stored encrypted video file data V3 according to the received retention time data L1.

Therefore, through the audio and video data storage method 400 of Figure 2, the digital audio and video data V1 of the conference system host 220 can be processed and encrypted through the conversion server 120 of the streaming conference device 100, and the processed encrypted video file data V3 can be transmitted to the storage module 340 for storage through the conversion server 120. The encrypted video file data V3 stored in the storage module 340 can be managed through the retention time data L1 to reduce the disk space of the conference system host 220 occupied by the digital audio and video data V1, reduce the system burden of the conference system host 220, reduce the burden on the administrator of the conference system host 220, and improve the security of the conference system host 220 and the storage security of sensitive data.

Please refer to FIG. 3 , which illustrates an operation flow chart for the streaming conferencing device 100 of FIG. 1 and the video and audio data storage method 400 of FIG. 2 . As shown in Figure 3, digital audio and video data V1 from the conference system 200 (i.e., the conference system host 220) is transmitted to the conversion server 120 of the streaming conference device 100. The conversion server 120 generates encrypted video file data V3 based on the digital audio and video data V1 and transmits the encrypted video file data V3 to the storage module 340 of the storage system 300 for storage. After the user 500 logs in and verifies through a login module (not shown), the user can use the decryption key D1 generated by the video file transmission module 140 of the streaming conference device 100 to download and decrypt the encrypted video file data V3 to obtain the audio and video data content of the encrypted video file data V3.

Therefore, by using the streaming conferencing device 100 and its audio and video data storage method 400 disclosed herein, the disk space occupied by the digital audio and video data V1 on the conference system host 220 can be reduced, thereby reducing the system burden on the conference system host 220 and the burden on the administrator of the conference system host 220. This can also improve the security of the conference system host 220 and the storage security of sensitive data.

Although specific embodiments of the present disclosure have been described with reference to the above-described embodiments, these embodiments are not intended to limit the present disclosure. Various substitutions and modifications may be made by those skilled in the relevant art without departing from the principles and spirit of the present disclosure. Therefore, the scope of protection of the present disclosure is determined by the appended patent applications.
