Sensitive data efficient transmission system based on data pre-identification

The invention provides a sensitive data efficient transmission system based on data pre-identification. The transmission system is used for data transmission and processing between a user terminal and a processor. The transmission system comprises an input module, a pre-identification module and a data encryption module which are arranged in a user terminal, the input module is used for a user to input data, the pre-identification module is used for classifying the input data, and the data encryption module is used for differentially encrypting the classified data; the transmission system further comprises a decryption module arranged in the processor, the decryption module is used for decrypting the encrypted data, on one hand, the sensitive data can be pre-screened, and on the other hand, the sensitive data can be subjected to hierarchical encryption processing in a targeted mode; and the high efficiency of sensitive data transmission is improved, and the security of sensitive data transmission is ensured a
