Detailed Description
To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1 and 2, a conference synchronization method of the present invention is schematically shown, including the following steps:
step S1, performing device performance detection on the receiving terminal to estimate the time that the receiving terminal needs to spend in decrypting and obtain the decrypting time of the receiving terminal, and the receiving terminal feeds back the decrypting time to the sending terminal. The conference synchronization method is compatible with receiving terminals of different brands and models, and the equipment performance detection of the receiving terminals includes but is not limited to obtaining hardware parameters of the receiving terminals and detecting the data processing performance of the receiving terminals through existing equipment performance test software.
In step S10, the plurality of receiving terminals receive the conference file transmitted by the sending terminal, and the receiving terminal encrypts the conference file to obtain an encrypted file, so that the plurality of receiving terminals can download and transmit the conference file first, but the conference file is encrypted to be the encrypted file, and therefore, the user cannot read the encrypted file. Of course, the encryption means for the conference file include, but are not limited to, the existing DES encryption algorithm, RSA encryption algorithm, and AES encryption algorithm. Note that the conference file includes office documents, audio, video, and the like.
And step 20, after the receiving terminal completes the encryption of the conference file, the receiving terminal sends encryption feedback information to the sending terminal, and the sending terminal can know the encryption condition of each receiving terminal.
In order to avoid the whole file transmission process from being jammed due to encryption timeout, the method further comprises the following steps:
step S21, judging whether the time for sending the encryption feedback information by the receiving terminal exceeds a time threshold, if so, outputting error prompt information to prompt a user of the sending terminal and a user of the receiving terminal to process transmission errors in time; otherwise, execution continues with step S22.
And step S22, judging whether the sending terminal requests to withdraw the conference file, if so, deleting the encrypted file by the receiving terminal, otherwise, executing step S30. This step enables the user of the sending terminal to actively request revocation of the conference file, providing more operability for the user.
And step S30, after receiving the encryption feedback information of the plurality of receiving terminals, the sending terminal transmits decryption data to the receiving terminals, the decryption data comprises decryption delay information generated according to the decryption time, and the receiving terminals decrypt the encrypted file according to the decryption data to obtain the conference file. The decryption delay information is used for unifying the decryption completion time of each receiving terminal.
For example, the transmitting terminal transmits a conference file to the first receiving terminal and the second receiving terminal, the device performance of the first receiving terminal is superior to that of the second receiving terminal, namely the decryption time of the first receiving terminal is less than the decryption time of the second receiving terminal, the first receiving terminal and the second receiving terminal encrypt respective conference files and feed back encryption feedback information, the sending terminal synchronously sends decryption data to the first receiving terminal and the second receiving terminal, the decryption delay information received by the first receiving terminal indicates the first receiving terminal to delay a yield time for decryption operation, the yielding time is an absolute value of a difference between the decryption time of the first receiving terminal and the decryption time of the second receiving terminal, and the decryption delay information received by the second receiving terminal instructs the second receiving terminal to immediately perform the decryption operation, so that the decryption completion time of the first receiving terminal and the second receiving terminal is basically the same.
And step S40, the receiving terminal sends the decryption feedback information to the sending terminal, and the user of the sending terminal can know that the user of the receiving terminal can read the conference file.
Because the data volume of the decrypted data is far smaller than that of the conference file, the transmission time of the decrypted data between the sending terminal and the receiving terminal is extremely short, so that users of a plurality of receiving terminals can synchronously obtain the reading and access rights of the conference file.
In order to solve the same technical problem, as shown in fig. 3, the present invention further provides a conference synchronization apparatus, including:
the encryption module 100 is configured to encrypt the conference file to obtain an encrypted file.
And an encryption feedback module 200, configured to send the encryption feedback information to the sending terminal.
And the decryption module 300 is configured to decrypt the encrypted file according to the decryption data to obtain the conference file.
A delay information generating module 400, configured to generate decryption delay information according to the decryption time.
And a decryption feedback module 500, configured to send decryption feedback information to the sending terminal.
In order to solve the same technical problem, the present invention further provides an electronic device, which includes a processor, a memory, and a computer program stored on the memory and executable on the processor, wherein the processor implements the conference synchronization method when executing the computer program.
In order to solve the same technical problem, the present invention also provides a computer readable storage medium storing computer instructions, which when executed by a processor implement the steps of the conference synchronization method described above.
Compared with the prior art, the invention has the beneficial effects that:
the receiving terminals encrypt the conference files after receiving the conference files and wait for decryption data of the sending terminal, so that the receiving terminals can download and transmit the conference files first, the sending terminal synchronously sends the decryption data to the receiving terminals after receiving the encryption feedback information, the receiving terminals synchronously decrypt the encrypted files, and conference participants with the receiving terminals can synchronously obtain access rights of the conference files to synchronously acquire the conference files.
