A secure image transmission scheme based on JPEG2000 codec is proposed in this paper, which combines encryption with encoding and is suitable for real-time applications. In this scheme, the sensitive data are self-authenticated, then partial-encrypted during compression process, and the compressed data are encrypted by the lightweight encryption algorithm combined with error-correction codec. The self-authentication process can detect malicious tampering or transmission errors. The encryption process obtains suitable tradeoff between security and time-efficiency through encrypting data adaptively, and keeps the original system's error-robustness. The decryption process is symmetric to the encryption process. Experimental results show that this scheme obtains high perception security and time efficiency, and is thus suitable for secure image transmission over network.
