Baconian Cipher
Bacon's cipher or the Baconian cipher is a method of steganographic message encoding devised by Francis Bacon in 1605. In steganography, a message is concealed in the presentation of text, rather than its content. Baconian ciphers are categorized as both a substitution cipher (in plain code) and a concealment cipher (using the two typefaces). Cipher details To encode a message, each letter of the plaintext is replaced by a group of five of the letters 'A' or 'B'. This replacement is a 5-bit binary encoding and is done according to the alphabet of the Baconian cipher (from the Latin Alphabet), shown below: A second version of Bacon's cipher uses a unique code for each letter. In other words, ''I'', ''J'', ''U'' and ''V'' each have their own pattern in this variant: The writer must make use of two different typefaces for this cipher. After preparing a false message with the same number of letters as all of the ''As'' and ''Bs'' in the real, secret message, two typefaces are c ...

First Folio
''Mr. William Shakespeare's Comedies, Histories, & Tragedies'' is a collection of plays by William Shakespeare, commonly referred to by modern scholars as the First Folio, published in 1623, about seven years after Shakespeare's death. It is considered one of the most influential books ever published. Printed in Folio (printing), folio format and containing 36 of Shakespeare's plays#Canonical plays, Shakespeare's plays, it was prepared by Shakespeare's colleagues John Heminges and Henry Condell. It was dedication (publishing), dedicated to the "incomparable pair of brethren" William Herbert, 3rd Earl of Pembroke, and his brother Philip Herbert, 4th Earl of Pembroke, Philip Herbert, Earl of Montgomery (later 4th Earl of Pembroke). Although 19 of Shakespeare's plays had been published in quarto before 1623, the First Folio is arguably the only reliable text for about 20 of the plays, and a valuable source text for many of those previously published. Eighteen of the plays in the Fir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

William Friedman
William Frederick Friedman (September 24, 1891 – November 2, 1969) was a United States Army, US Army cryptography, cryptographer who ran the research division of the Army's Signal Intelligence Service (SIS) in the 1930s, and parts of its follow-on services into the 1950s. In 1940, subordinates of his led by Frank Rowlett broke Japan's Purple (cipher machine), PURPLE cipher, thus disclosing Japanese diplomatic secrets before America's entrance into World War II. Early life Friedman was born Wolf Friedman (, ), in Kishinev, Bessarabia Governorate, Bessarabia, the son of Frederick Friedman, a Jew from Bucharest who worked as a translator and linguist for the Russian Postal Service, and the daughter of a well-to-do wine merchant. Friedman's family left Kishinev in 1892 on account of anti-Semitic persecution, ending up in Pittsburgh, Pennsylvania. Three years later, his first name was changed to William.

Baudot Code
The Baudot code () is an early character encoding for telegraphy invented by Émile Baudot in the 1870s. It was the predecessor to the International Telegraph Alphabet No. 2 (ITA2), the most common teleprinter code in use before ASCII. Each character in the alphabet is represented by a series of five bits, sent over a communication channel such as a telegraph wire or a radio signal by asynchronous serial communication. The symbol rate measurement is known as baud, and is derived from the same name. History Baudot code (ITA1) In the below table, Columns I, II, III, IV, and V show the code; the Let. and Fig. columns show the letters and numbers for the Continental and UK versions; and the sort keys present the table in the order: alphabetical, Gray and UK Baudot developed his first multiplexed telegraph in 1872 [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cryptography
Cryptography, or cryptology (from "hidden, secret"; and ''graphein'', "to write", or ''-logy, -logia'', "study", respectively), is the practice and study of techniques for secure communication in the presence of Adversary (cryptography), adversarial behavior. More generally, cryptography is about constructing and analyzing Communication protocol, protocols that prevent third parties or the public from reading private messages. Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, information security, electrical engineering, digital signal processing, physics, and others. Core concepts related to information security (confidentiality, data confidentiality, data integrity, authentication, and non-repudiation) are also central to cryptography. Practical applications of cryptography include electronic commerce, Smart card#EMV, chip-based payment cards, digital currencies, password, computer passwords, and military communications. ...

Steganography
Steganography ( ) 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 computing/electronic contexts, a computer file, message, image, or video is concealed within another file, message, image, or video. Generally, the hidden messages appear to be (or to be part of) something else: images, articles, shopping lists, or some other cover text. For example, the hidden message may be in invisible ink between the visible lines of a private letter. Some implementations of steganography that lack a formal shared secret are forms of security through obscurity, while key-dependent steganographic schemes try to adhere to Kerckhoffs's principle. The word ''steganography'' comes from Greek ''steganographia'', which combines the words ''steganós'' (), meaning "covered or concealed", and ''-graphia'' () meaning "writing". The fir ...

Baconian Theory Of Shakespeare Authorship
The Baconian theory of Shakespearean authorship contends that Francis Bacon, Sir Francis Bacon, philosopher, essayist and scientist, wrote the Shakespeare's plays, plays that are attributed to William Shakespeare. Various explanations are offered for this alleged subterfuge, most commonly that Bacon's rise to high office might have been hindered if it became known that he wrote plays for the public stage. The plays are credited to Shakespeare, who, supporters of the theory claim, was merely a front to shield the identity of Bacon. All but a few academic Shakespeare scholars reject the arguments for Bacon authorship, as well as those for all List of Shakespeare authorship candidates, other alternative authors. The theory was first put forth in the mid-nineteenth century, based on perceived correspondences between the philosophical ideas found in Bacon’s writings and the works of Shakespeare. Legal and autobiographical allusions and cryptographic ciphers and codes were later fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Typeface
A typeface (or font family) is a design of Letter (alphabet), letters, Numerical digit, numbers and other symbols, to be used in printing or for electronic display. Most typefaces include variations in size (e.g., 24 point), weight (e.g., light, bold), slope (e.g., italic), width (e.g., condensed), and so on. Each of these variations of the typeface is a font. There are list of typefaces, thousands of different typefaces in existence, with new ones being developed constantly. The art and craft of designing typefaces is called type design. Designers of typefaces are called type designers and are often employed by type foundry, type foundries. In desktop publishing, type designers are sometimes also called "font developers" or "font designers" (a typographer is someone who ''uses'' typefaces to design a page layout). Every typeface is a collection of glyphs, each of which represents an individual letter, number, punctuation mark, or other symbol. The same glyph may be used for ch ...
