The phrase “graphical identification and authentication” does not appear to correspond to a widely recognized, standalone concept in established encyclopedic references. Consequently, there is no dedicated entry describing it as a distinct field or technology.
Possible interpretation
The wording combines two common security‑related ideas:
-
Graphical identification – the use of visual elements (images, icons, patterns, or sketches) to represent or verify a user’s identity. Examples include avatar selection, visual cues on biometric devices, or image‑based user profiles.
-
Authentication – the process of confirming that a user or system is who or what it claims to be, typically through something the user knows (a password), has (a token), or is (biometrics).
When coupled, “graphical identification and authentication” is plausibly used to describe authentication schemes that rely on images rather than alphanumeric passwords. In the security literature, such approaches are more commonly referred to as graphical passwords, picture‑based authentication, or visual authentication. Research prototypes have explored methods like “draw‑a‑secret,” “pass‑points,” and “cued click‑points,” where users must recognize or recreate a previously chosen image pattern to gain access.
Contextual usage
Some academic papers and technical reports may employ the phrase loosely to denote a class of image‑oriented authentication mechanisms. However, it lacks a standardized definition, formal specifications, or widespread adoption comparable to established terms such as “graphical password” or “visual cryptography.”
Conclusion
Because the term is not documented as a distinct, widely acknowledged concept in reliable encyclopedic sources, the entry provides only a brief contextual explanation of how it may be interpreted within the broader domain of image‑based security methods.
