The invention relates to the technical field of information hiding, and particularly relates to a JPEG image robustness steganography method based on a serial concatenated code and a DCT coefficient relative relationship. The JPEG image robustness steganography method based on the serial concatenated code and the DCT coefficient relative relationship comprises the steps of determining a modification area; designing a corresponding distortion function; encoding a to-be-embedded message by using an error correcting code; embedding the error correcting code through robustness steganography; performing JPEG compression; obtaining an information stream containing errors by using steganographic translated code, and correcting errors by using a translated code of the error correcting code; and obtaining the original embedded message. JPEG compression attacks of different quality factors can be defended in a larger range, the embedded message can be extracted completely at a higher probability, further, for same secret information, the method has higher detection resistance.
