For a recorder which is verified to upload illegal data, relevant personnel need to review clearly and solve problems, and then have the authority to upload video again.
In another embodiment of the present invention, when the encrypted real-time video is transmitted by infrasonic waves, the server platform may receive the encrypted real-time video in the middle of transmitting the encrypted real-time video, which may result in incomplete reception of the ciphertext, and may misjudge the video as an illegal video. In order to solve the problem, after ciphertext data are obtained in the step A1, N binary opening codes are added in front of the ciphertext data so that the integrity of the ciphertext data can be verified by a platform, the ciphertext data and the opening codes are transmitted to an infrasonic wave generator by a control center MCU, and the infrasonic wave generator superposes the infrasonic wave generator on infrasonic waves with certain frequency to be transmitted.
As shown in fig. 3, in step a2, the server platform verifies the real-time video, separates infrasonic data from the sound data of the real-time video, and if the infrasonic data can be separated, ciphertext data will be obtained, which is different from fig. 2:
if the front of the obtained ciphertext data is N binary open codes, the ciphertext data is judged to be complete ciphertext data, the received complete ciphertext data is decrypted and verified, and whether the ciphertext data is legal or not is judged.
If the front of the obtained ciphertext data is not N binary open codes, the obtained ciphertext data is judged to be incomplete ciphertext data, and the server platform continues to wait for the verification of the next complete ciphertext data.
Preferably, the N binary on codes are set to 8 1 binary on codes.
Preferably, before the infrasonic wave sends the ciphertext data, 8 1 binary open codes are sent first, so that the server platform receives the 8 1 binary open codes and judges that the complete ciphertext data is behind the 1 binary open codes. If 8 opening codes are not received, if the video is uploaded in midway, the data is judged to be incomplete ciphertext data, and the next opening code is waited, and then the ciphertext is received for verification.
The control center MCU constantly controls the infrasonic generator to transmit the ciphertext data binary code, taking the ciphertext data 3252195127371235 as an example, the infrasonic generator transmits the corresponding binary code: 1011100011011101101010101111010011101010010111100011, after the front face 10111000 is transmitted, real-time video uploading is carried out, 11011101101010101111010011101010010111100011 is when the server platform receives infrasonic data, the infrasonic generator does not add an opening code before the ciphertext data, if the beginning of the infrasonic data received by the server platform is not 11111111, the data is considered to be incomplete, the data is judged to be incomplete ciphertext data, and the server platform continues to wait for receiving the infrasonic data of which the opening code is 11111111111. Adding 8 binary 1 turn-on codes, and transmitting binary codes: 111111111011100011011101101010101111010011101010010111100011, when the beginning of the infrasonic data received by the server platform is 11111111, the data is considered to be complete, the data immediately below is complete ciphertext data, and the subsequent decoding verification work can be carried out to judge whether the data is legal data; after the reception is completed, the reception of the infrasonic data whose on code is 11111111 is continuously waited.
This application adopts the encryption signal of infrasonic wave transmission real-time video, has utilized following characteristics:
the infrasonic wave is lower than the auditory frequency range of human ears, and has strong concealment. Meanwhile, infrasonic waves are not easy to attenuate and absorbed by water and air, and can be well recorded by a recorder.
