User data encryption and decryption method and device and electronic equipment

Abstract

The invention provides a user data encryption and decryption method and device and electronic equipment, and the encryption method comprises the steps: receiving input to-be-encrypted first video data which is uncompressed data; selecting a frame of image with specific characteristics from the first video data to generate secret key image data, and determining an encryption secret key according to the secret key image data and a gray scale level; compressing the to-be-encrypted first video data to obtain second video data, and symmetrically encrypting the second video data according to the encryption key to obtain encrypted data; inserting the image with the specific feature into the encrypted data according to a preset rule to form a ciphertext so as to form a message request frame according to the ciphertext; and sending the ciphertext in response to the received response message. According to the method provided by the invention, the security of data transmission is ensured, in addition, the feature information of the video can be judged without decrypting the data, and the waste of decryption resources caused by transmission errors is avoided.

[0003] In order to ensure the authenticity and real-time of operating users, verification methods such as pictures and text are difficult to meet high-security scenarios. The more reliable verification method is to verify by recording videos in real time. Depending on the usage scenario, it may be necessary to record corresponding videos. As a credential for identity authentication, since the recorded data needs to be sent to the server for interpretation, security issues during data transmission are more prominent. In order to ensure safe transmission, video data needs to be encrypted, but unlike other types of data, video is usually There is a large amount of data, encryption is complex due to high complexity, and if it is encrypted first and then compressed, the compression efficiency will be reduced, and the use of a unified secret key for encryption will also reduce security
