Tokenization (data Security)
Tokenization, when applied to data security, is the process of substituting a sensitive data element with a non-sensitive equivalent, referred to as a Security token, token, that has no intrinsic or exploitable meaning or value. The token is a reference (i.e. identifier) that maps back to the sensitive data through a tokenization system. The mapping from original data to a token uses methods that render tokens infeasible to reverse in the absence of the tokenization system, for example using tokens created from Random number generation, random numbers. A one-way cryptographic function is used to convert the original data into tokens, making it difficult to recreate the original data without obtaining entry to the tokenization system's resources. To deliver such services, the system maintains a vault database of tokens that are connected to the corresponding sensitive data. Protecting the system vault is vital to the system, and improved processes must be put in place to offer dat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Currency
A currency is a standardization of money in any form, in use or circulation as a medium of exchange, for example banknotes and coins. A more general definition is that a currency is a ''system of money'' in common use within a specific environment over time, especially for people in a nation state. Under this definition, the British Pound sterling (£), euros (€), Japanese yen (¥), and U.S. dollars (US$) are examples of (government-issued) fiat currencies. Currencies may act as stores of value and be traded between nations in foreign exchange markets, which determine the relative values of the different currencies. Currencies in this sense are either chosen by users or decreed by governments, and each type has limited boundaries of acceptance; i.e., legal tender laws may require a particular unit of account for payments to government agencies. Other definitions of the term ''currency'' appear in the respective synonymous articles: banknote, coin, and money. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Payment Card
Payment cards are part of a payment system issued by financial institutions, such as a bank, to a customer that enables its owner (the cardholder) to access the funds in the customer's designated bank accounts, or through a credit account and make payments by electronic transfer with a payment terminal and access automated teller machines (ATMs). Such cards are known by a variety of names, including bank cards, ATM cards, client cards, key cards or cash cards. There are a number of types of payment cards, the most common being credit cards, debit cards, charge cards, and prepaid cards. Most commonly, a payment card is electronically linked to an account or accounts belonging to the cardholder. These accounts may be deposit accounts or loan or credit accounts, and the card is a means of authenticating the cardholder. However, stored-value cards store money on the card itself and are not necessarily linked to an account at a financial institution. The largest global card pa ...

Surrogate Key
A surrogate key (or synthetic key, pseudokey, entity identifier, factless key, or technical key) in a database is a unique identifier for either an ''entity'' in the modeled world or an ''object'' in the database. The surrogate key is ''not'' derived from application data, unlike a ''natural'' (or ''business'') key. Definition There are at least two definitions of a surrogate: ; Surrogate (1) – Hall, Owlett and Todd (1976): A surrogate represents an ''entity'' in the outside world. The surrogate is internally generated by the system but is nevertheless visible to the user or application. ; Surrogate (2) – Wieringa and De Jonge (1991): A surrogate represents an ''object'' in the database itself. The surrogate is internally generated by the system and is invisible to the user or application. The ''Surrogate (1)'' definition relates to a data model rather than a storage model and is used throughout this article. See Date (1998). An important distinction between a s ...

Exonumia
Exonumia are numismatic items (such as tokens, medals, or scrip) other than coins and paper money. This includes "Good For" tokens, badges, counterstamped coins, elongated coins, encased coins, souvenir medallions, tags, wooden nickels and other similar items. It is an aspect of numismatics and many coin collectors are also exonumists. Besides the above strict definition, others extend it to include non-coins which may or may not be legal tenders such as cheques, credit cards and similar paper. These can also be considered notaphily or scripophily. Etymology The noun ''exonumia'' is derived from two classical roots: ''exo'', meaning "out-of" in Greek, and '' nummus'', meaning "coin" in Latin (from Greek νοῦμμος – ''noummos'', "coin"); thus, "out ideof- he categoryoins". The equivalent British term, paranumismatica, may also be used. The words ''exonumist'' and ''exonumia'' were coined in July 1960 by Russell Rulau, a recognized authority and author on th ...
