Ecash
Ecash was conceived by David Chaum as an anonymous cryptographic electronic money or electronic cash system in 1983. It was realized through his corporation Digicash and used as micropayment system at one US bank from 1995 to 1998. Design Chaum published the idea of anonymous electronic money in a 1983 paper; eCash software on the user's local computer stored money in a digital format, cryptographically signed by a bank. The user could spend the digital money at any shop accepting eCash, without having to open an account with the vendor first, or transmitting credit card numbers. Security was ensured by public key digital signature schemes. The RSA blind signatures achieved unlinkability between withdrawal and spend transactions. Depending on the payment transactions, one distinguishes between on-line and off-line electronic cash: If the payee has to contact a third party (e.g., the bank or the credit-card company acting as an acquirer) before accepting a payment, the system is cal ...

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 ...

Digital Currencies
Digital currency (digital money, electronic money or electronic currency) is any currency, money, or money-like asset that is primarily managed, stored or exchanged on digital computer systems, especially over the internet. Types of digital currencies include cryptocurrency, virtual currency and central bank digital currency. Digital currency may be recorded on a distributed database on the internet, a centralized electronic Database, computer database owned by a company or bank, within Computer file, digital files or even on a stored-value card. Digital currencies exhibit properties similar to traditional currencies, but generally do not have a classical physical form of fiat currency historically that you can directly hold in your hand, like currencies with printed banknotes or minted coins - however they do have a physical form in an unclassical sense coming from the computer to computer and computer to human interactions and the information and processing power of the serve ...

David Chaum
David Lee Chaum (born 1955) is an American computer scientist, cryptographer, and inventor. He is known as a pioneer in cryptography and privacy-preserving technologies, and widely recognized as the inventor of digital cash. His 1982 dissertation "Computer Systems Established, Maintained, and Trusted by Mutually Suspicious Groups" is the first known proposal for a blockchain protocol. Complete with the code to implement the protocol, Chaum's dissertation proposed all but one element of the blockchain later detailed in the Bitcoin whitepaper. He has been referred to as "the father of online anonymity", and "the godfather of cryptocurrency". He is also known for developing ecash, an electronic cash application that aims to preserve a user's anonymity, and inventing many cryptographic protocols like the blind signature, mix networks and the Dining cryptographers protocol. In 1995 his company DigiCash created the first digital currency with eCash.Greenberg, Andy (2012). ''This M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cryptographic Protocols
A security protocol (cryptographic protocol or encryption protocol) is an abstract or concrete protocol that performs a security-related function and applies cryptographic methods, often as sequences of cryptographic primitives. A protocol describes how the algorithms should be used and includes details about data structures and representations, at which point it can be used to implement multiple, interoperable versions of a program. Cryptographic protocols are widely used for secure application-level data transport. A cryptographic protocol usually incorporates at least some of these aspects: * Key agreement or establishment * Entity authentication * Symmetric encryption and message authentication material construction * Secured application-level data transport * Non-repudiation methods * Secret sharing methods * Secure multi-party computation Secure multi-party computation (also known as secure computation, multi-party computation (MPC) or privacy-preserving computation) is a ...

E-commerce
E-commerce (electronic commerce) is the activity of electronically buying or selling of products on online services or over the Internet. E-commerce draws on technologies such as mobile commerce, electronic funds transfer, supply chain management, Internet marketing, online transaction processing, electronic data interchange (EDI), inventory management systems, and automated data collection systems. E-commerce is in turn driven by the technological advances of the semiconductor industry, and is the largest sector of the electronics industry. Defining e-commerce The term was coined and first employed by Dr. Robert Jacobson, Principal Consultant to the California State Assembly's Utilities & Commerce Committee, in the title and text of California's Electronic Commerce Act, carried by the late Committee Chairwoman Gwen Moore (D-L.A.) and enacted in 1984. E-commerce typically uses the web for at least a part of a transaction's life cycle although it may also use other techno ...

Blucora
Infospace, Inc. was an American company that offered private label search engine, online directory, and provider of metadata feeds. The company's flagship metasearch site was Dogpile and its other notable consumer brands were WebCrawler and MetaCrawler. After a 2012 rename to Blucora, the InfoSpace business unit was sold to data management company OpenMail. History The company was founded in March 1996 by Naveen Jain after he left Microsoft. The company started with six employees, and Jain served as CEO until 2000. InfoSpace provided content and services, such as phone directories, maps, games and information on the stock market, to websites and mobile device manufacturers. The company grew at low cost without funding using co-branding strategies. Rather than try to get traffic to an InfoSpace website, sites like Lycos, Excite and Playboy embedded InfoSpace's features and content into their site and added an InfoSpace icon to it. InfoSpace then earned money by taking a small perce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
