Cryptography
Cryptography, or cryptology (from grc, , translit=kryptós "hidden, secret"; and ''graphein'', "to write", or ''-logia'', "study", respectively), is the practice and study of techniques for secure communication in the presence of adversarial behavior. More generally, cryptography is about constructing and analyzing 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 ( data confidentiality, data integrity, authentication, and non-repudiation) are also central to cryptography. Practical applications of cryptography include electronic commerce, chip-based payment cards, digital currencies, computer passwords, and military communications. Cryptography prior to the modern age was effectively synonymo ...

Electronic Privacy Information Center
Electronic Privacy Information Center (EPIC) is an independent nonprofit research center in Washington, D.C. EPIC's mission is to focus public attention on emerging privacy and related human rights issues. EPIC works to protect privacy, freedom of expression, and democratic values, and to promote the Public Voice in decisions concerning the future of the Internet. EPIC pursues a wide range of civil liberties, consumer protection, and human rights issues. EPIC has pursued several successful consumer privacy complaints with the US Federal Trade Commission, concerning Snapchat (faulty privacy technology), WhatsApp (privacy policy after acquisition by Facebook), Facebook (changes in user privacy settings), Google (roll-out of Google Buzz), Microsoft (Hailstorm log-in), and Choicepoint (sale of personal information to identity thieves). EPIC has also prevailed in significant Freedom of Information Act cases against the CIA, the DHS, the Dept. of Education, the Federal Bureau of Invest ...

DigiCash
DigiCash Inc. was an electronic money corporation founded by David Chaum in 1989. DigiCash transactions were unique in that they were anonymous due to a number of cryptographic protocols developed by its founder. DigiCash declared bankruptcy in 1998 and subsequently sold its assets to eCash Technologies, another digital currency company, which was acquired by InfoSpace on Feb. 19, 2002. History David Chaum is associated with the invention of Blind Signature Technology. In 1982, while studying at the University of California, Berkeley, Chaum wrote a paper describing the technological advancements to public and private key technology, in order to create this Blind Signature Technology. Chaum's Blind Signature Technology was designed to ensure the complete privacy of users who conduct online transactions. Chaum was concerned with the public nature and open access to online payments and personal information. He then proposed to construct a system of cryptographic protocols, in which ...

U-Prove
U-Prove is a free and open-source technology and accompanying SDK for user-centric identity management. The underlying cryptographic protocols were designed by Dr. Stefan Brands and further developed by Credentica and, subsequently, Microsoft. The technology was developed to allow internet users to disclose only the minimum amount of personal data when making electronic transactions as a way to reduce the likelihood of privacy violations. Security expert Bruce Schneier praised the cryptography behind U-Prove. Overview U-Prove enables application developers to reconcile seemingly conflicting security and privacy objectives (including anonymity), and allows for digital identity claims to be efficiently tied to the use of tamper-resistant devices such as smart cards. Application areas of particular interest include cross-domain enterprise identity and access management, e-government SSO and data sharing, electronic health records, anonymous electronic voting, policy-based digital ri ...
