Biometrics are body measurements and calculations related to human characteristics and features. Biometric 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.

Web Authentication (WebAuthn) is a web standard published by the World Wide Web Consortium (W3C). It defines an API that websites use to authenticate with WebAuthn credentials (passkeys) and outlines what WebAuthn authenticators should do. It solves many of the issues of traditional password-based authentication by verifying the user's identity with digital signatures. Although WebAuthn is often touted as a complete replacement for passwords, most websites that implement it continue to use passwords in some capacity.

The eIDAS Regulation (for "electronic IDentification, Authentication and trust Services") is an EU regulation with the stated purpose of governing "electronic identification and trust services for electronic transactions". It passed in 2014 and its provisions came into effect between 2016 and 2018.

Microprinting is the production of recognizable patterns or characters in a printed medium at a scale that typically requires magnification to read with the naked eye. To the unaided eye, the text may appear as a solid line. Attempts to reproduce by methods of photocopy, image scanning, or pantograph typically translate as a dotted or solid line, unless the reproduction method can identify and recreate patterns to such scale. Microprint is predominantly used as an anti-counterfeiting technique, due to its inability to be easily reproduced by widespread digital methods.

Huaya ("flower seal"; ; ; , Vietnamese: , chữ Hán: ) are stylized signatures or marks used in East Asian cultures in place of a fully written signature. Originating from China, the huaya was historically used by prominent figures such as government officials, monks, artists, and craftsmen. The use of stamp seals gradually replaced the huaya, though they are still used occasionally in modern times by important people.
