Now the methodology I used just exposes the type of hidden message and not the message itself. The message unfortunatly for us appears to be hidden in the JPHIDE which utilizes a password based encryption so without the password it will be impossible to figure out the message. Although we do know that there is something there.


****disclaimer: the way the analysis tools that I have scan the data it looks for missing voids in repeating color sections of the photo (complex photos with lots of colors are best for hiding). When I tested with normal sensitivity I didn't see any result, but on cranking up the sensitivity I found proof of an encryption. With all things like this it is possible to get a false positive, but since this is all for fun anyway we can just assume it is there.



so what do we think the password is? I might try to make a dictionary and brute force it later after I am done with the bench top test of the new control system.

In my opinions this was just a fish picture scanned from a book with very thin paper so the words are backwards because they are on next page. Onion skin paper and <40gsm paper like bible paper is common for big dictionary like books.
