Secure Electronic Transaction (SET) is a communications protocol standard for securing credit card transactions over networks, specifically, the Internet.SET was not itself a payment system, but rather a set of security protocols and formats that enabled users to employ the existing credit card payment infrastructure on an open network in a secure fashion.
Grey relational analysis. Grey relational analysis ( GRA) was developed by Deng Julong of Huazhong University of Science and Technology. It is one of the most widely used models of grey system theory. GRA uses a specific concept of information. It defines situations with no information as black, and those with perfect information as white.
In graph theory, a dominating set for a graph G is a subset D of its vertices, such that any vertex of G is in D, or has a neighbor in D. The domination number γ (G) is the number of vertices in a smallest dominating set for G . The dominating set problem concerns testing whether γ (G) ≤ K for a given graph G and input K; it is a classical ...
Website. www .gra .gov .gh. The Ghana Revenue Authority (GRA) is the Ghana administration charged with the task of assessing, collecting and accounting for tax revenue in Ghana. [1] [2] As part of efforts to improve compliance, the Authority is required to assist taxpayers to understand and meet their tax obligations by providing robust and ...
Private set intersection. Private set intersection is a secure multiparty computation cryptographic technique [1] that allows two parties holding sets to compare encrypted versions of these sets in order to compute the intersection. In this scenario, neither party reveals anything to the counterparty except for the elements in the intersection.
Security holograms are labels with a hologram printed onto it for sale security reasons. It is argued by the International Hologram Manufacturers Association that holograms on security labels are difficult to forge because they are replicated from a master hologram which requires expensive specialized and technologically advanced equipment.

A secure element (SE) is a secure operating system (OS) in a tamper-resistant processor chip or secure component. It can protect assets (root of trust, sensitive data, keys, certificates, applications) against high-level software and hardware attacks. Applications that process this sensitive data on an SE are isolated and so operate within a ...
3-D Secure is a protocol designed to be an additional security layer for online credit and debit card transactions. The name refers to the "three domains" which interact using the protocol: the merchant/acquirer domain, the issuer domain, and the interoperability domain. [1]
