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 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 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 database integrity and physical security. ...

Currency
A currency, "in circulation", from la, currens, -entis, literally meaning "running" or "traversing" 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 "c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
End-to-end Encryption
End-to-end encryption (E2EE) is a system of communication where only the communicating users can read the messages. In principle, it prevents potential eavesdroppers – including telecommunications service providers, telecom providers, Internet providers, malicious actors, and even the provider of the communication service – from being able to access the Key (cryptography), cryptographic keys needed to Encryption, decrypt the conversation. End-to-end encryption is intended to prevent data being read or secretly modified, other than by the true sender and recipient(s). The messages are encrypted by the sender but the third party does not have a means to decrypt them, and stores them encrypted. The recipients retrieve the encrypted data and decrypt it themselves. Because no third parties can decipher the data being communicated or stored, for example, companies that provide end-to-end encryption are unable to hand over texts of their customers' messages to the authorities.

In response, he launched United Bank Card in his parents' basement in Far Hills, New Jersey. At the time, it generally took merchants about one month to set up a payment system and merchants had to pay for their credit card readers and sign a lengthy application. As an alternative, Isaacman's new company cut the ... [...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 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. It can also be a smart card that contains a unique card ...

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 ...

Scrip
A scrip (or ''chit'' in India) is any substitute for legal tender. It is often a form of credit. Scrips have been created and used for a variety of reasons, including exploitive payment of employees under truck systems; or for use in local commerce at times when regular currency was unavailable, for example in remote coal towns, military bases, ships on long voyages, or occupied countries in wartime. Besides company scrip, other forms of scrip include land scrip, vouchers, token coins such as subway tokens, IOUs, arcade tokens and tickets, and points on some credit cards. Scrips have gained historical importance and become a subject of study in numismatics and exonumia due to their wide variety and recurring use. Scrip behaves similarly to a currency, and as such can be used to study monetary economics. History A variety of forms of scrip were used at various times in the 19th and 20th centuries. Company scrip Company scrip was a credit against the accrued wages of e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 related to numismatics (concerned with coins which have been legal tender), 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". Usually, the term "exonumia" is applied to these objects in the United States, while the equivalent British term is paranumismatica. The words '' ...

Banknote
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 t ...
