Here's a few.
'strip scowl broil drink spate' - It's not hard to find plenty more,
'cookie'
At 1st, the only obvious similarity that I saw was...
OWL could be all around us, like AIR
........ NOT via rot13 but via skip ciphers. Skip ciphers are a nifty
way to embed secrets in ordinary text; they were in common use 420 years
ago during the Golden Age of the London theater.
i recently learned of this word
steganography (veiled-writing, hiding a message in plain sight)
________________________
Steganography is the practice of hiding secret messages, data, or code
within another seemingly ordinary file or medium so that its very
existence goes completely unnoticed. Unlike cryptography, which
scrambles a message to make it unreadable, steganography conceals the
message in plain sight. [1, 2, 3, 4, 5]
Here are some of the most common and fascinating real-world examples of steganography, broken down by medium:
Efu+N+A Digital Media
rCo Least Significant Bit (LSB): In digital images or audio, secret text
or data can be embedded by modifying the last bit of the bytes that make
up a file's pixels or sound waves. These color or audio shifts are so
tiny that the naked eye or human ear cannot detect the change.
rCo Audio Spectrograms: Some musicians or artists secretly encode images
or text into a song's audio track. If you play the song normally, it
sounds fine, but if you look at the track's visual audio frequency (spectrogram), the hidden image or text appears.
rCo Metadata & Headers: Secrets can be concealed by altering file
headers, appending data to the very end of an executable (EXE) file, or
hiding data in an image's EXIF data. [14, 15, 16, 17, 18]
Efu?N+A Physical & Hardware
rCo Printer Steganography: Many color laser printers silently print a
tracking pattern of microscopic, pale yellow dots (Machine
Identification Codes) on every page. Invisible to the naked eye, these
dots contain encoded timestamps and the printer's serial number to trace documents.
rCo Invisible Ink & Microdots: Classic espionage techniques, such as
using chemical compounds that only appear under UV light/heat, or
reducing a full-page document into a tiny dot attached to innocent
paperwork. [21, 22]
EfA+ Cybersecurity
rCo Malware Obfuscation: Hackers frequently use image steganography to
hide malicious payloads inside an innocent-looking JPEG photo. Because
the image appears safe, it can easily bypass firewalls and antivirus
software, only releasing the malicious code once it is inside the target system.
rCo Digital Watermarks: Photographers and companies embed hidden, copyright-protecting data into the pixels of their digital art to prove ownership. [11, 24]
rLeN+A Text & Linguistics
rCo Acrostics: Writing an innocent-seeming message, but ensuring the
first or last letters of each sentence or paragraph spell out a hidden
word (e.g., hiding the word "HELP" in a letter using the first letter of
each sentence).
rCo Linguistic Substitutions: Swapping certain words for functionally equivalent synonyms to hide data, such as mapping specific verbs or
structures to act as binary 0s or 1s. [14, 26, 27, 28]
If you want to dive deeper into how these techniques are applied, you
can explore the List of steganography techniques - Wikipedia or read
through the Steganography: Hiding Data In Plain Sight lecture from UNC
Computer Science. [19, 29, 30]
If you'd like, I can:
rCo Provide a mathematical breakdown of how the LSB algorithm works.
rCo Explain the difference between steganography and cryptography in
detail.
rCo Recommend popular ethical hacking tools used to embed/extract hidden
data. [6, 23, 24, 31, 32]
