Biometrics is the technical term for body measurements and calculations.

It refers to metrics related to human characteristics.

Biometrics authentication (or realistic authentication) is used in computer science as a form of identification and access control.

It is also used to identify individuals in groups that are under surveillance.

SMS (short message service) is a text messaging service component of most telephone, internet, and mobile-device systems.

It uses standardized communication protocols to enable mobile devices to exchange short text messages.

An intermediary service can facilitate a text-to-voice conversion to be sent to landlines.

Authentication (from authentikos, "real, genuine", from αὐθέντης authentes, "author") is the act of confirming the truth of an attribute of a single piece of data claimed true by an entity.

In contrast with identification, which refers to the act of stating or otherwise indicating a claim purportedly attesting to a person or thing's identity, authentication is the process of actually confirming that identity.

It might involve confirming the identity of a person by validating their identity documents, verifying the authenticity of a website with a digital certificate, determining the age of an artifact by carbon dating, or ensuring that a product is what its packaging and labeling claim to be.

In other words, authentication often involves verifying the validity of at least one form of identification.

A one-time password or pin (OTP) is a password that is valid for only one login session or transaction, on a computer system or other digital device.

OTPs avoid a number of shortcomings that are associated with traditional (static) password-based authentication; a number of implementations also incorporate two factor authentication by ensuring that the one-time password requires access to something a person has (such as a small keyring fob device with the OTP calculator built into it, or a smartcard or specific cellphone) as well as something a person knows (such as a PIN).

Cryptography or cryptology (from "hidden, secret"; and graphein, "to write", or -logia, "study", respectively) is the practice and study of techniques for secure communication in the presence of third parties called adversaries.

More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages; various aspects in information security such as data confidentiality, data integrity, authentication, and non-repudiation are central to modern cryptography.

Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, electrical engineering, communication science, and physics.

Applications of cryptography include electronic commerce, chip-based payment cards, digital currencies, computer passwords, and military communications.
