Puff is a free steganography and authoring program.
Obviously steganography is not a new idea, but you can check out the steganography interface that Puff has, designed for people who know what they need.
Bits selection level:
You can process each kind of carrier in 7 different ways: unhiding complexity grows by 7 per kind of carrier used.
Encryption algorhythm:
16 different encryption algorhythms, with 16 subvariants, that makes 256. Exactly every possible byte value!
Moreover, algorhythms sequence is random-generated.
PASSWORD ENCRYPTION:
Password encryption algorhythm has been designed to produce a high amount of fixed redundant values. Obviously this increases unallowed unhiding attempts complexity.
CARRIERS CHAINS:
Hiding data is split among many carrier. Only the correct carrier sequence enables unhiding: unhiding complexity grows by n!, where n is carriers number. Moreover, up to 256Mb can be hidden, if you have enough carriers at disposal. Last carrier will be filled with random bits in order to make it undistinguishable from others.
n=01 >> n!=1
n=02 >> n!=2
n=03 >> n!=6
n=04 >> n!=24
n=05 >> n!=120
n=06 >> n!=720
n=07 >> n!=5040
n=08 >> n!=40320
n=09 >> n!=362880
n=10 >> n!=3628800
etc...
Alphabetical processing:
At hiding time, carriers are processed in alphabetical order. No low-level physical mark of their logical order will hence be available.
SUMMARY:
Someone could be able to debug this program and discover the cryptographic algorhythm (it would be a huge, not impossible, but enormous work). Even in this case a simple 20-carriers chain with 3 different kinds of carrier could need 4e+19 unhiding tries by unallowed people, password protection left out of count! High performances can be achieved only with full understanding of all the tricky options that are offered to you.
AUTHORING:
Simplified version of hiding process is available for authoring. One more chance to sign your work!
Each carrier will work as a single carrier chain.
Carrier bits will be filled with your copyright mark.
No password protection, encryption or compressing will be performed.
Puff will work as a public interface for checking copyright integrity. The only required setting is bits selection level used at authoring time.
Puff supports images (BMP, JPG, PCX, PNG, TGA), audios (AIFF, MP3, NEXT/SUN, WAV) and Win PE modules.
