The present invention is applied to the field of monitoring, and provides a private data transmission method and system. The method includes the following steps: the data sending terminal performs encrypt packing to the private data, and transmits a data packet bearing private data to a data receiving terminal, wherein the data packet includes an encryption algorithm ID encrypting the private data and cipher key ID; the data receiving terminal resolves the data packet bearing private data, acquires decipher cipher key and corresponding decipher method from the server according to the encryption algorithm ID and cipher key ID carried by the data packet, to decipher the private data. In the present invention, the existing mature encryption algorithm is used to encrypt the private data and a RTP packet is used to transmit the private data, the data receiving terminal acquires decipher cipher key and decipher method from the server according to the encrypt method ID and cipher key ID carried by the RTP packet, pl
