The commet thingy sounds interesting, and makes a lot more sense than going around playing with file formats.. i'll go check it out.

The gif->jpg transition would go something like:

1. Generate gif
2. Convert to jpg
3. Bit fiddle
4. send to browser

The advantage i can see in this, is if the output jpg is modified the fingerprint is destroyed, hence the modified jpg is a fake.

the downside is it's an expensive process..
