Verification and validation, in engineering or quality management systems, is the act of reviewing, inspecting or testing, in order to establish and document that a product, service or system meets regulatory or technical standards
Verifier can refer to: A machine, such as the IBM 056, used in two pass verification; The Verifier, a type of fuel gauge; See also. Verification (disambiguation)
Verification is intended to check that a product, service, or system meets a set of design specifications. [6] [7] In the development phase, verification procedures involve performing special tests to model or simulate a portion, or the entirety, of a product, service, or system, then performing a review or analysis of the modeling results.
In the context of hardware and software systems, formal verification is the act of proving or disproving the correctness of a system with respect to a certain formal specification or property, using formal methods of mathematics. [1]
A broad definition of verification makes it related to software testing. In that case, there are two fundamental approaches to verification: Dynamic verification, also known as experimentation, dynamic testing or, simply testing. - This is good for finding faults (software bugs).
The definition of M&S validation focuses on the accuracy with which the M&S represents the real-world intended use(s). Determining the degree of M&S accuracy is required because all M&S are approximations of reality, and it is usually critical to determine if the degree of approximation is acceptable for the intended use(s).
The issuer and holder trust each other, the holder trusts the verifier, and the verifier trusts the issuer. Any role in the triangle can be played by a person, an institution, or an IoT device. Verifiable credentials (VCs) are digital credentials which follow the relevant World Wide Web Consortium open standards .
Data verification is a process in which different types of data are checked for accuracy and inconsistencies after data migration is done. [1] In some domains it is referred to Source Data Verification (SDV), such as in clinical trials.
