No. There are algorithms out there that can survive compression[1] by encoding statistically over an image instead of just bit manipulation. You can also embed data in the audio channel by alternating between two imperceptible echo kernels for 1/0[2]. This is extremely compression resistant. 1: http://ieeexplore.ieee.org/xpl/articleDetails.jsp?tp=&arnumber=4428921&url=http%3A%2F%2Fieeexplore.ieee.org%2Fxpls%2Fabs_all.jsp%3Farnumber%3D4428921 http://ieeexplore.ieee.org/xpl/articleDetails.jsp?tp=&arnumb... 2: http://www.slidefinder.net/a/audio_steganography_echo_data_hiding/jeff_england_audio_steganography/24367218 http://www.slidefinder.net/a/audio_steganography_echo_data_h...
