The invention discloses a multimedia information safe transmission method based on wireless communication technology. After receiving the multimedia source information, a source information acquisition module performs asymmetric encryption operation on the source information through an encryption algorithm, and the asymmetric encryption operation obtains an asymmetric public key and a private key,and the public key encrypts and protects the source information. Sending the encrypted information out and transmitting the encrypted information to the target node through the information transmission module. The access monitoring module is used for monitoring and comparing the target information in the transmission path during the transmission process, and the information inquiry module is usedto explore the transmission path of encrypted security information and the interference of external information. The encrypted information transmitted to the target node is decrypted by the private key, and the encrypted information is transmitted to the information instruction execution unit after being verified to be correct. The invention can strengthen the privacy in the multimedia information transmission process, and can intercept the interference information in the transmission path, ensure the safety in the information transmission process, and prevent the information from being lost.
