I agree with Viva, distortion makes the most sense here.

Wait, is this really how steganography works? Seems odd.

Definitely the cover generation technique!

I think it's the substitution technique, not distortion.

Sounds like the distortion technique to me!

I’m leaning towards the spread spectrum technique, but I can't recall exactly how it differs from the others in terms of altering the cover.

This sounds similar to a practice question I did on steganography, and I think the cover generation technique was about creating new covers, not modifying existing ones.

I'm not entirely sure, but I remember something about the substitution technique being related to replacing parts of the cover.

I think this might be the distortion technique since it involves changing the cover object to hide information.

I'm pretty confident the answer is B, the substitution technique. The question describes Victor changing the cover object to hide information, which is exactly what the substitution technique does - it replaces parts of the cover with the hidden data.

Okay, let me think this through. The question says Victor is changing the cover object to hide information, and that the secret info is recovered by comparing the changed cover to the original. That makes me think the distortion technique might be the right answer, since that involves modifying the cover in a way that hides the message.

Hmm, I'm a bit unsure about this one. The question mentions Victor is using a "certain steganography technique," but doesn't specify which one. I'll need to carefully consider each of the options to determine the best fit based on the information given.

This seems like a straightforward steganography question. I think the key is to focus on the details provided - Victor is using a cover object and changing it to hide information, which is then recovered by comparing the changed cover to the original. Based on that, I'm leaning towards the substitution technique.

I heard Victor's using the 'secret handshake' technique. You know, where he's just tapping out the message in Morse code on the cover object. Gotta keep it old school, am I right?

The distortion technique? That's a new one to me. I bet Victor is trying to confuse the heck out of his friend with that one!

Hmm, the cover generation technique seems interesting. I wonder if Victor is creating a completely new cover object to hide the message.

The spread spectrum technique sounds like it could be the answer. It's all about dispersing the secret data across the cover object, making it harder to detect.

I think Victor is using the substitution technique. It's a classic steganography method where he changes the cover object to hide the secret information.
