And S2, setting the authority level of the participating device, wherein the participating device can operate the file based on the authority level, and the operation comprises uploading, consulting and downloading.
When the authority level of the participating device is higher than the authority level of the participating device, setting the priority level of the participating device according to the priority level of the participating device, wherein the priority level of the participating device is set by a host; for example, a company's high-level administration, which gives the highest priority, can perform all operations on a file.
S3, constructing a shared file library, wherein the shared file library comprises a plurality of levels of file repositories, and the file repositories correspond to the authority levels of the participating devices one to one;
the shared file library is essentially a database, and mysql, oracle, sqlserver, sqlite, etc. can be used.
The authority levels of the file repositories correspond to the authority levels of the participating devices one by one, and the high-priority participating devices can perform all operations on the file repositories with low priorities; the authority of the low-priority participant equipment is set to be only uploaded, the low-priority participant equipment can only upload the authority for the high-priority participant equipment to operate, and only the participant equipment with the same priority can not refer to the storage file library with the same priority; the file can be protected to a certain extent, and the situation that the file is divulged is prevented.
S4, traversing all file input ports to obtain file input conditions;
if the file input is detected, storing the input file into a corresponding file storage based on the authority level of the participating equipment;
and if the file input is not detected, continuously traversing the file input port.
Through traversing the file input port, when the participating device uploads the file, the corresponding file can be automatically stored in the corresponding file storage library, and the conference host does not need to operate the file by distraction, so that the working content of the conference host can be reduced, and the efficiency of the online conference can be improved.
And if the file uploaded by the low-priority participating device needs higher security effect, the conference host can transfer the file from the low-priority file storage library to the high-priority file storage library so as to improve the authority of the file.
In the process of the online conference, if a part of files need to be shared; and acquiring a retrieval instruction of the host, retrieving the shared document library based on the retrieval instruction, extracting the documents in the shared document library and issuing the documents to the participating equipment with the appointed authority level. By setting the permission level, the participating devices can be grouped, and the host can find the required files more quickly through the retrieval instruction.
The retrieval instruction can be field retrieval, participant equipment retrieval, keyword retrieval or file type retrieval, through the retrieval instruction, the host can accurately position the required file, and through permission grouping, the retrieved file can be issued to the participant equipment with corresponding permission levels by one key, so that the conference system is more convenient to use, and the conference efficiency can be further improved.
Collecting audio and video information input by the participants, separating and identifying voice (audio) information in the audio and video information, converting the audio and video information into text information, and preprocessing the text information; the preprocessing method comprises the steps of deleting, marking and associating, deleting and deleting invalid information in the text information; marking, namely marking the text information based on the identification and the authority level of the participating equipment; and associating the plurality of pieces of text information with the same mark.
Establishing a conference summary database in the shared file database, and storing the preprocessed text information into the conference summary database; when storing, the mark is used as a main key for storage, so as to facilitate retrieval. The indicia is associated with identity information of the conference participants.
The conference summary database can acquire the sound characteristic information and the identity information of each participant in advance, and store the acquired sound characteristic information and the acquired identity information in the sound characteristic database in a correlated manner. For example, a piece of audio/video information of each participant can be acquired before a meeting; for example, each participant reads the same sentence, and extracts the sound characteristic information of the participant from the audio and video information. The voice feature information and the identity information stored in the voice feature library have a one-to-one correspondence relationship with the marks.
When the audio and video information of the user is collected in the conference process, the sound characteristic information of the user can be extracted from the collected audio and video information, and the extracted sound characteristic information is matched and compared with the sound characteristic information stored in the sound characteristic library; and if the similarity between the extracted sound characteristic information and the target sound characteristic information stored in the sound characteristic library is satisfied, taking the identity information which is stored in the sound characteristic library and is associated with the target sound characteristic information as the mark of the user.
When an online conference is carried out, audio and video information of participants can be collected through the participant equipment; after the audio and video information is collected, the audio and video information is identified and processed, and the voice information in the audio and video information is converted into text information, and the identification processing can adopt a common voice identification method in the prior art, such as a voice identification method disclosed in chinese patent document with application publication No. CN109215637A, which is not described herein again.
