Printer Steganography
A Machine Identification Code (MIC), also known as printer steganography, yellow dots, tracking dots or secret dots, is a digital watermark which certain color laser printers and copiers leave on every printed page, allowing identification of the device which was used to print a document and giving clues to the originator. Developed by Xerox and Canon in the mid-1980s, its existence became public only in 2004. In 2018, scientists developed privacy software to anonymize prints in order to support whistleblowers publishing their work. History In the mid-1980s Xerox pioneered an encoding mechanism for a unique number represented by tiny dots spread over the entire print area. Xerox developed the machine identification code "to assuage fears that their color copiers could be used to counterfeit bills" and received U.S. Patent No 5515451 describing the use of the yellow dots to identify the source of a copied or printed document. The public first became aware of MIC in October 2004, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Reality Winner
Reality Leigh Winner (born December 4, 1991) is an American former enlisted US Air Force member and NSA translator. In 2018, she was given the longest prison sentence ever imposed for unauthorized release of government information to the media after she leaked an intelligence report about Russian interference in the 2016 United States elections. She was sentenced to five years and three months in federal prison. On June 3, 2017, while employed by the military contractor Pluribus International Corporation, Winner was arrested on suspicion of leaking an intelligence report about Russian interference in the 2016 United States elections from the National Security Agency (NSA) to the news website ''The Intercept''. The report indicated that Russian hackers accessed voter registration rolls in the United States with an email phishing operation, though it was unclear whether any changes had been made. Concerns were raised that ''The Intercept''s handling of the material exposed her as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Intercept
''The Intercept'' is an American left-wing news website founded by Glenn Greenwald, Jeremy Scahill, Laura Poitras and funded by billionaire eBay co-founder Pierre Omidyar. Its current editor is Betsy Reed. The publication initially reported on documents released by Edward Snowden and was considered to be "activist voice for privacy and civil liberties". Co-founders Greenwald and Poitras subsequently left amid public disagreements about the leadership and direction of the organization. In recent years, the website's editorial stance has become more closely aligned with the hard-left of the Democratic Party. It was among the first to report on the campaign of Alexandria Ocasio-Cortez, and often criticizes moderate democrats from a left-wing perspective. Its editorial policy explicitly rejects "mandating balance" when covering stories. ''The Intercept'' has published in English since its founding, and in Portuguese since the 2016 launch of the Brazilian edition staffed b ...

Defense Advanced Research Projects Agency
The Defense Advanced Research Projects Agency (DARPA) is a research and development agency of the United States Department of Defense responsible for the development of emerging technologies for use by the military. Originally known as the Advanced Research Projects Agency (ARPA), the agency was created on February 7, 1958, by President Dwight D. Eisenhower in response to the Soviet launching of Sputnik 1 in 1957. By collaborating with academia, industry, and government partners, DARPA formulates and executes research and development projects to expand the frontiers of technology and science, often beyond immediate U.S. military requirements.Dwight D. Eisenhower and Science & Technology, (2008). Dwight D. Eisenhower Memorial CommissionSource ''The Economist'' has called DARPA the agency "that shaped the modern world," and pointed out that " Moderna's COVID-19 vaccine sits alongside weather satellites, GPS, drones, stealth technology, voice interfaces, the personal computer ...

DARPA Shredder Challenge 2011
DARPA Shredder Challenge 2011 was a prize competition for exploring methods to reconstruct documents shredded by a variety of paper shredding techniques. The aim of the challenge was to "assess potential capabilities that could be used by the U.S. warfighters operating in war zones, but might also identify vulnerabilities to sensitive information that is protected by shredding practices throughout the U.S. national security community". The competition was sponsored by the Defense Advanced Research Projects Agency (DARPA), a research organization of the United States Department of Defense. Congress authorized DARPA to award cash prizes to further DARPA’s mission to sponsor revolutionary, high-payoff research that bridges the gap between fundamental discoveries and their use for national security. Under the rules of the competition, the $50,000 challenge award would be granted to the first team to submit the answers to questions relating to a hidden mystery. The mystery verified ...

Visible Spectrum
The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called ''visible light'' or simply light. A typical human eye will respond to wavelengths from about 380 to about 750 nanometers. In terms of frequency, this corresponds to a band in the vicinity of 400–790 terahertz. These boundaries are not sharply defined and may vary per individual. Under optimal conditions these limits of human perception can extend to 310 nm (ultraviolet) and 1100 nm (near infrared). The optical spectrum is sometimes considered to be the same as the visible spectrum, but some authors define the term more broadly, to include the ultraviolet and infrared parts of the electromagnetic spectrum as well. The spectrum does not contain all the colors that the human visual system can distinguish. '' Unsaturated colors'' such as pink, or purple variations like magenta, for example, are a ...

Bank Note
A banknote—also called a bill (North American English), paper money, or simply a note—is a type of negotiable promissory note, made by a bank or other licensed authority, payable to the bearer on demand. Banknotes were originally issued by commercial banks, which were legally required to redeem the notes for legal tender (usually gold or silver coin) when presented to the chief cashier of the originating bank. These commercial banknotes only traded at face value in the market served by the issuing bank. Commercial banknotes have primarily been replaced by national banknotes issued by central banks or monetary authorities. National banknotes are often – but not always – legal tender, meaning that courts of law are required to recognize them as satisfactory payment of money debts. Historically, banks sought to ensure that they could always pay customers in coins when they presented banknotes for payment. This practice of "backing" notes with something of substance is ...

Steganographic
Steganography ( ) is the practice of representing information within another message or physical object, in such a manner that the presence of the information is not evident to human inspection. In computing/electronic contexts, a computer file, message, image, or video is concealed within another file, message, image, or video. The word ''steganography'' comes from Greek ''steganographia'', which combines the words ''steganós'' (), meaning "covered or concealed", and ''-graphia'' () meaning "writing". The first recorded use of the term was in 1499 by Johannes Trithemius in his '' Steganographia'', a treatise on cryptography and steganography, disguised as a book on magic. 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 shared secret are ...
