Join Director of Product Management Todd OBoyle on April 26th as he covers the key elements of a phishing protection program. Whether you’re an old hat at phishing education or considering starting a program -- we'll discuss critical components that should be in any program.
f.e. Color nuances are fuzzy (so you can hide data to some extend in a jpeg), just don;t use a picture multiple times (ie also not publishing am original).
You can define a much higher resolution version in the color spectrum than can actualy be seen. So you can slip in bits which are
humans can distinguish about 64 levels of color shades at most. So having a space of 256 levels gives you room to fix 2 bits per pixel that go indistinguishable. (24bit colourspace)
Structured data is a problem. The only imprecise stuff in a programming language/xml is the naming of constants & variables.
But if you change them in one part you need to change it in a lot of parts in a consistent way, otherwise it could be detectable wit a simple build task...?
but do you get enough free bits with that? At least variable names need te be meaningless rather long names to start with...
At least in a movie you might get more bits as the stream has a lot more bits i.e. you can use less bits per image which would avoid some detection.
