Not with a one-time pad or a similar derivative like you have developed. I
limit my claims to the following three points.
- Steganography is detectable.
- Simple encryption is brute-force crackable.
- Cipher codes are statistically decodeable.
I do not claim any weakness in one-time pads, extremely small messages, or
trigger signals that do not contain the actual data.
However, I am still waiting for someone to send me undetectable
steganography. This was the original topic of this thread. I have already
accepted (nonmonetary) challenges on that score. Thus far, I have correctly
identified seven pictures sent to me. They were admittedly trivial to
detect. I have not received any "serious" attempts at undetectable
I remain undefeated at detecting steganography. I would love to get a real
challenge that is not trivial to detect. I would even enjoy failing such a
challenge, because it might signal hope for the development of undetectable
steganography. Thus far, however, I see no evidence that undetectable
steganography is even theoretically possible.
