You could go the computer game approach and use a custom binary packing 
algorithm where you compress all of that data into a single file which your 
program then unpacks when it runs everything. That is assuming that you have a 
sort of main program that runs the system. People *might* reverse-engineer your 
format (ie. the DOOM WAD file), but probably the number of people interested in 
doing so will be small.

Since pd patches are just text files, you could use any text to binary encoding 
format etc. This of course starts heading into encryption territory, but that’s 
a whole other thing there...

Re: [PD] Obfuscate patch?

[Mario Mey]

Thanks everybody.

Why would you want to do something like that?


I live in Argentina and I'm going to work with an agent in Spain. I 
developed and I offer the service of "Digital Puppeteers". So, this 
agent will offer the same service and he will contact me when he find a 
client. So, I prepare "the files" and I send him... and he pay to me.


Now, "the files" are the important thing here. They are Blender, Python, 
JSON and PureData files. Somehow, no-one of that formats can be compiled 
to send him the binary. Also, I can't afford contracting a hardware key 
system... or pay a programmer to make some online validation code.


If I send the files as they are in my computer (clean code, 
documentation, etc), in the worst case, he could never call me back... 
and start using the files for him, changing a few graphic files, audio 
files, code lines, patches, etc.


So, the only thing I can do... is to obfuscate as much I can.

Python: strings, keys, values, functions, classes, etc
Blender: objects, bones, scenes, materials and textures names, inserting 
extra scenes, textures, etc

JSON: everything.
PureData: send/receive names, messages from/to Blender, moving boxes, 
adding extra objects, etc.


And, of course, all that obfuscated names have to be the same between 
the files.



What about simply changing all object coords other than inlet/outlet to (0, 0)?

Good one.

yes, iirc multiple times.
- [parazit] (used to be shipped with Pd-extended)
- i remember a few patches from the local pd~graz gang around 2004 that
would go into that direction (including self-destruction)
- personally i have used self-replicating, self-renaming and moving
objects in a number of performances [sinusoiddreams]
(much of the iemguts development was driven to implement those systems).

I'll look at them!

kinda antithetical to the ethos of Pure Data
I posted my biggest PureData project in PatchStorage (and the old one, 
too). This patch is very specific.

among other reasons, http://www.ioccc.org/
When I saw inside the code files... it made sense to me. They made me 
laught.

I am an external patch obfuscator; nobody can understand the things that I 
write in PD.

I will hire you! :D

Ok in that sense, sure... Maybe I was biased by the other thread about 
"commercial" Pd projects...


Still the OP hasn't revealed their real intentions, maybe in an attempt 
to obfuscate them :)

that's a Max problem, fixed in Pd, the only thing is that you should be
careful with the outlet positions of abstractions. The order could change.

i agree - kinda antithetical to the ethos of Pure Data, really. i think you
could use Heavy to turn a patch into rather voluminous C++ code. i remember
from the devs that they said the code output wasn't supposed to be edited
or analyzed by humans, but rather existed to be wrapped to work in a number
of environments as sort of a black box or code blob. but obfuscating a PD
patch itself seems stupid. i'm sure you could name subpatches and
abstractions randomly and maybe even rearrange the physical placement using
the method Jonathan refers to, though i believe that could affect signal
flow and execution order, wouldn't it?

best,
scott
