The same image viewed by white, blue, green, and red lights reveals different hidden numbers. Steganography (/ ˌ s t ɛ ɡ ə ˈ n ɒ ɡ r ə f i / ⓘ STEG-ə-NOG-rə-fee) is the practice of representing information within another message or physical object, in such a manner that the presence of the concealed information would not be evident to an unsuspecting person's examination.
In 2020, Zhongliang Yang et al. discovered that for text generative steganography, when the quality of the generated steganographic text is optimized to a certain extent, it may make the overall statistical distribution characteristics of the generated steganographic text more different from the normal text, making it easier to be recognized.
The word 'steganography', encoded with quotation marks, where standard text represents "typeface 1" and text in boldface represents "typeface 2": To encode a message each letter of the plaintext is replaced by a group of five of the letters 'A' or 'B'. The pattern of standard and boldface letters is:

Printer tracking dots, also known as printer steganography, DocuColor tracking dots, yellow dots, secret dots, or a machine identification code (MIC), is a digital watermark which many color laser printers and photocopiers produce on every printed page that identifies the specific device that was used to print the document.
In classical cryptography, a null is an extra character intended to confuse the cryptanalyst.In the most common form of a null cipher, the plaintext is included within the ciphertext and one needs to discard certain characters in order to decrypt the message (such as first letter, last letter, third letter of every second word, etc.) [1] Most characters in such a cryptogram are nulls, only ...
However, since the publication of a decryption key to the first two volumes in 1606, they were discovered to be actually concerned with cryptography and steganography. Until 1996, the third volume was widely believed to be solely about magic, but the "magical" formulas have now been shown to be covertexts for yet more material on cryptography.
For example, a common artifact in JPEG compression is "edge ringing", where high-frequency components (such as the high-contrast edges of black text on a white background) distort neighboring pixels. This distortion is predictable, and simple steganographic encoding algorithms will produce artifacts that are detectably unlikely.
